-/**
- * The BreakIterator class implements methods for finding the location
- * of boundaries in text. BreakIterator is an abstract base class.
- * Instances of BreakIterator maintain a current position and scan over
- * text returning the index of characters where boundaries occur.
- * <p>
- * Line boundary analysis determines where a text string can be broken
- * when line-wrapping. The mechanism correctly handles punctuation and
- * hyphenated words.
- * <p>
- * Sentence boundary analysis allows selection with correct
- * interpretation of periods within numbers and abbreviations, and
- * trailing punctuation marks such as quotation marks and parentheses.
- * <p>
- * Word boundary analysis is used by search and replace functions, as
- * well as within text editing applications that allow the user to
- * select words with a double click. Word selection provides correct
- * interpretation of punctuation marks within and following
- * words. Characters that are not part of a word, such as symbols or
- * punctuation marks, have word-breaks on both sides.
- * <p>
- * Character boundary analysis allows users to interact with
- * characters as they expect to, for example, when moving the cursor
- * through a text string. Character boundary analysis provides correct
- * navigation of through character strings, regardless of how the
- * character is stored. For example, an accented character might be
- * stored as a base character and a diacritical mark. What users
- * consider to be a character can differ between languages.
- * <p>
- * The text boundary positions are found according to the rules
- * described in Unicode Standard Annex #29, Text Boundaries, and
- * Unicode Standard Annex #14, Line Breaking Properties. These
- * are available at http://www.unicode.org/reports/tr14/ and
- * http://www.unicode.org/reports/tr29/.
- * <p>
- * In addition to the C++ API defined in this header file, a
- * plain C API with equivalent functionality is defined in the
- * file ubrk.h
- * <p>
- * Code snippits illustrating the use of the Break Iterator APIs
- * are available in the ICU User Guide,
- * http://icu-project.org/userguide/boundaryAnalysis.html
- * and in the sample program icu/source/samples/break/break.cpp"

+/**
+ * The BreakIterator class implements methods for finding the location
+ * of boundaries in text. BreakIterator is an abstract base class.
+ * Instances of BreakIterator maintain a current position and scan over
+ * text returning the index of characters where boundaries occur.
+ * <p>
+ * Line boundary analysis determines where a text string can be broken
+ * when line-wrapping. The mechanism correctly handles punctuation and
+ * hyphenated words.
+ * <p>
+ * Sentence boundary analysis allows selection with correct
+ * interpretation of periods within numbers and abbreviations, and
+ * trailing punctuation marks such as quotation marks and parentheses.
+ * <p>
+ * Word boundary analysis is used by search and replace functions, as
+ * well as within text editing applications that allow the user to
+ * select words with a double click. Word selection provides correct
+ * interpretation of punctuation marks within and following
+ * words. Characters that are not part of a word, such as symbols or
+ * punctuation marks, have word-breaks on both sides.
+ * <p>
+ * Character boundary analysis allows users to interact with
+ * characters as they expect to, for example, when moving the cursor
+ * through a text string. Character boundary analysis provides correct
+ * navigation of through character strings, regardless of how the
+ * character is stored. For example, an accented character might be
+ * stored as a base character and a diacritical mark. What users
+ * consider to be a character can differ between languages.
+ * <p>
+ * The text boundary positions are found according to the rules
+ * described in Unicode Standard Annex #29, Text Boundaries, and
+ * Unicode Standard Annex #14, Line Breaking Properties. These
+ * are available at http://www.unicode.org/reports/tr14/ and
+ * http://www.unicode.org/reports/tr29/.
+ * <p>
+ * In addition to the C++ API defined in this header file, a
+ * plain C API with equivalent functionality is defined in the
+ * file ubrk.h
+ * <p>
+ * Code snippits illustrating the use of the Break Iterator APIs
+ * are available in the ICU User Guide,
+ * http://icu-project.org/userguide/boundaryAnalysis.html
+ * and in the sample program icu/source/samples/break/break.cpp"

-/**
- * <code>Calendar</code> is an abstract base class for converting between
- * a <code>UDate</code> object and a set of integer fields such as
- * <code>YEAR</code>, <code>MONTH</code>, <code>DAY</code>, <code>HOUR</code>,
- * and so on. (A <code>UDate</code> object represents a specific instant in
- * time with millisecond precision. See UDate
- * for information about the <code>UDate</code> class.)
- *
- * <p>
- * Subclasses of <code>Calendar</code> interpret a <code>UDate</code>
- * according to the rules of a specific calendar system.
- * The most commonly used subclass of <code>Calendar</code> is
- * <code>GregorianCalendar</code>. Other subclasses could represent
- * the various types of lunar calendars in use in many parts of the world.
- *
- * <p>
- * <b>NOTE</b>: (ICU 2.6) The subclass interface should be considered unstable
- * - it WILL change.
- *
- * <p>
- * Like other locale-sensitive classes, <code>Calendar</code> provides a
- * static method, <code>createInstance</code>, for getting a generally useful
- * object of this type. <code>Calendar</code>'s <code>createInstance</code> method
- * returns the appropriate <code>Calendar</code> subclass whose
- * time fields have been initialized with the current date and time:
- * \htmlonly<blockquote>\endhtmlonly
- * <pre>
- * Calendar *rightNow = Calendar::createInstance(errCode);
- * </pre>
- * \htmlonly</blockquote>\endhtmlonly
- *
- * <p>
- * A <code>Calendar</code> object can produce all the time field values
- * needed to implement the date-time formatting for a particular language
- * and calendar style (for example, Japanese-Gregorian, Japanese-Traditional).
- *
- * <p>
- * When computing a <code>UDate</code> from time fields, two special circumstances
- * may arise: there may be insufficient information to compute the
- * <code>UDate</code> (such as only year and month but no day in the month),
- * or there may be inconsistent information (such as "Tuesday, July 15, 1996"
- * -- July 15, 1996 is actually a Monday).
- *
- * <p>
- * <strong>Insufficient information.</strong> The calendar will use default
- * information to specify the missing fields. This may vary by calendar; for
- * the Gregorian calendar, the default for a field is the same as that of the
- * start of the epoch: i.e., YEAR = 1970, MONTH = JANUARY, DATE = 1, etc.
- *
- * <p>
- * <strong>Inconsistent information.</strong> If fields conflict, the calendar
- * will give preference to fields set more recently. For example, when
- * determining the day, the calendar will look for one of the following
- * combinations of fields. The most recent combination, as determined by the
- * most recently set single field, will be used.
- *
- * \htmlonly<blockquote>\endhtmlonly
- * <pre>
- * MONTH + DAY_OF_MONTH
- * MONTH + WEEK_OF_MONTH + DAY_OF_WEEK
- * MONTH + DAY_OF_WEEK_IN_MONTH + DAY_OF_WEEK
- * DAY_OF_YEAR
- * DAY_OF_WEEK + WEEK_OF_YEAR
- * </pre>
- * \htmlonly</blockquote>\endhtmlonly
- *
- * For the time of day:
- *
- * \htmlonly<blockquote>\endhtmlonly
- * <pre>
- * HOUR_OF_DAY
- * AM_PM + HOUR
- * </pre>
- * \htmlonly</blockquote>\endhtmlonly
- *
- * <p>
- * <strong>Note:</strong> for some non-Gregorian calendars, different
- * fields may be necessary for complete disambiguation. For example, a full
- * specification of the historial Arabic astronomical calendar requires year,
- * month, day-of-month <em>and</em> day-of-week in some cases.
- *
- * <p>
- * <strong>Note:</strong> There are certain possible ambiguities in
- * interpretation of certain singular times, which are resolved in the
- * following ways:
- * <ol>
- * <li> 24:00:00 "belongs" to the following day. That is,
- * 23:59 on Dec 31, 1969 < 24:00 on Jan 1, 1970 < 24:01:00 on Jan 1, 1970
- *
- * <li> Although historically not precise, midnight also belongs to "am",
- * and noon belongs to "pm", so on the same day,
- * 12:00 am (midnight) < 12:01 am, and 12:00 pm (noon) < 12:01 pm
- * </ol>
- *
- * <p>
- * The date or time format strings are not part of the definition of a
- * calendar, as those must be modifiable or overridable by the user at
- * runtime. Use {@link DateFormat}
- * to format dates.
- *
- * <p>
- * <code>Calendar</code> provides an API for field "rolling", where fields
- * can be incremented or decremented, but wrap around. For example, rolling the
- * month up in the date <code>December 12, <b>1996</b></code> results in
- * <code>January 12, <b>1996</b></code>.
- *
- * <p>

+/**
+ * <code>Calendar</code> is an abstract base class for converting between
+ * a <code>UDate</code> object and a set of integer fields such as
+ * <code>YEAR</code>, <code>MONTH</code>, <code>DAY</code>, <code>HOUR</code>,
+ * and so on. (A <code>UDate</code> object represents a specific instant in
+ * time with millisecond precision. See UDate
+ * for information about the <code>UDate</code> class.)
+ *
+ * <p>
+ * Subclasses of <code>Calendar</code> interpret a <code>UDate</code>
+ * according to the rules of a specific calendar system.
+ * The most commonly used subclass of <code>Calendar</code> is
+ * <code>GregorianCalendar</code>. Other subclasses could represent
+ * the various types of lunar calendars in use in many parts of the world.
+ *
+ * <p>
+ * <b>NOTE</b>: (ICU 2.6) The subclass interface should be considered unstable
+ * - it WILL change.
+ *
+ * <p>
+ * Like other locale-sensitive classes, <code>Calendar</code> provides a
+ * static method, <code>createInstance</code>, for getting a generally useful
+ * object of this type. <code>Calendar</code>'s <code>createInstance</code> method
+ * returns the appropriate <code>Calendar</code> subclass whose
+ * time fields have been initialized with the current date and time:
+ * \htmlonly<blockquote>\endhtmlonly
+ * <pre>
+ * Calendar *rightNow = Calendar::createInstance(errCode);
+ * </pre>
+ * \htmlonly</blockquote>\endhtmlonly
+ *
+ * <p>
+ * A <code>Calendar</code> object can produce all the time field values
+ * needed to implement the date-time formatting for a particular language
+ * and calendar style (for example, Japanese-Gregorian, Japanese-Traditional).
+ *
+ * <p>
+ * When computing a <code>UDate</code> from time fields, two special circumstances
+ * may arise: there may be insufficient information to compute the
+ * <code>UDate</code> (such as only year and month but no day in the month),
+ * or there may be inconsistent information (such as "Tuesday, July 15, 1996"
+ * -- July 15, 1996 is actually a Monday).
+ *
+ * <p>
+ * <strong>Insufficient information.</strong> The calendar will use default
+ * information to specify the missing fields. This may vary by calendar; for
+ * the Gregorian calendar, the default for a field is the same as that of the
+ * start of the epoch: i.e., YEAR = 1970, MONTH = JANUARY, DATE = 1, etc.
+ *
+ * <p>
+ * <strong>Inconsistent information.</strong> If fields conflict, the calendar
+ * will give preference to fields set more recently. For example, when
+ * determining the day, the calendar will look for one of the following
+ * combinations of fields. The most recent combination, as determined by the
+ * most recently set single field, will be used.
+ *
+ * \htmlonly<blockquote>\endhtmlonly
+ * <pre>
+ * MONTH + DAY_OF_MONTH
+ * MONTH + WEEK_OF_MONTH + DAY_OF_WEEK
+ * MONTH + DAY_OF_WEEK_IN_MONTH + DAY_OF_WEEK
+ * DAY_OF_YEAR
+ * DAY_OF_WEEK + WEEK_OF_YEAR
+ * </pre>
+ * \htmlonly</blockquote>\endhtmlonly
+ *
+ * For the time of day:
+ *
+ * \htmlonly<blockquote>\endhtmlonly
+ * <pre>
+ * HOUR_OF_DAY
+ * AM_PM + HOUR
+ * </pre>
+ * \htmlonly</blockquote>\endhtmlonly
+ *
+ * <p>
+ * <strong>Note:</strong> for some non-Gregorian calendars, different
+ * fields may be necessary for complete disambiguation. For example, a full
+ * specification of the historial Arabic astronomical calendar requires year,
+ * month, day-of-month <em>and</em> day-of-week in some cases.
+ *
+ * <p>
+ * <strong>Note:</strong> There are certain possible ambiguities in
+ * interpretation of certain singular times, which are resolved in the
+ * following ways:
+ * <ol>
+ * <li> 24:00:00 "belongs" to the following day. That is,
+ * 23:59 on Dec 31, 1969 < 24:00 on Jan 1, 1970 < 24:01:00 on Jan 1, 1970
+ *
+ * <li> Although historically not precise, midnight also belongs to "am",
+ * and noon belongs to "pm", so on the same day,
+ * 12:00 am (midnight) < 12:01 am, and 12:00 pm (noon) < 12:01 pm
+ * </ol>
+ *
+ * <p>
+ * The date or time format strings are not part of the definition of a
+ * calendar, as those must be modifiable or overridable by the user at
+ * runtime. Use {@link DateFormat}
+ * to format dates.
+ *
+ * <p>
+ * <code>Calendar</code> provides an API for field "rolling", where fields
+ * can be incremented or decremented, but wrap around. For example, rolling the
+ * month up in the date <code>December 12, <b>1996</b></code> results in
+ * <code>January 12, <b>1996</b></code>.
+ *
+ * <p>
+ * <code>Calendar</code> also provides a date arithmetic function for
+ * adding the specified (signed) amount of time to a particular time field.
+ * For example, subtracting 5 days from the date <code>September 12, 1996</code>
+ * results in <code>September 7, 1996</code>.

- */
-
-U_NAMESPACE_BEGIN
-/**
- * Abstract class that defines an API for forward-only iteration
- * on text objects.
- * This is a minimal interface for iteration without random access
- * or backwards iteration. It is especially useful for wrapping
- * streams with converters into an object for collation or
- * normalization.
- *
- * <p>Characters can be accessed in two ways: as code units or as
- * code points.
- * Unicode code points are 21-bit integers and are the scalar values
- * of Unicode characters. ICU uses the type UChar32 for them.
- * Unicode code units are the storage units of a given
- * Unicode/UCS Transformation Format (a character encoding scheme).
- * With UTF-16, all code points can be represented with either one
- * or two code units ("surrogates").
- * String storage is typically based on code units, while properties
- * of characters are typically determined using code point values.
- * Some processes may be designed to work with sequences of code units,
- * or it may be known that all characters that are important to an
- * algorithm can be represented with single code units.
- * Other processes will need to use the code point access functions.</p>
- *
- * <p>ForwardCharacterIterator provides nextPostInc() to access
- * a code unit and advance an internal position into the text object,
- * similar to a <code>return text[position++]</code>.<br>
- * It provides next32PostInc() to access a code point and advance an internal
- * position.</p>
- *
- * <p>next32PostInc() assumes that the current position is that of
- * the beginning of a code point, i.e., of its first code unit.
- * After next32PostInc(), this will be true again.
- * In general, access to code units and code points in the same
- * iteration loop should not be mixed. In UTF-16, if the current position
- * is on a second code unit (Low Surrogate), then only that code unit
- * is returned even by next32PostInc().</p>
- *
- * <p>For iteration with either function, there are two ways to
- * check for the end of the iteration. When there are no more
- * characters in the text object:
- * <ul>
- * <li>The hasNext() function returns FALSE.</li>
- * <li>nextPostInc() and next32PostInc() return DONE
- * when one attempts to read beyond the end of the text object.</li>
- * </ul>
- *
- * Example:
- * \code
- * void function1(ForwardCharacterIterator &it) {
- * UChar32 c;
- * while(it.hasNext()) {
- * c=it.next32PostInc();
- * // use c
- * }
- * }
- *
- * void function1(ForwardCharacterIterator &it) {
- * UChar c;
- * while((c=it.nextPostInc())!=ForwardCharacterIterator::DONE) {
- * // use c
- * }
- * }
- * \endcode
- * </p>

-/**
- * Abstract class that defines an API for iteration
- * on text objects.
- * This is an interface for forward and backward iteration
- * and random access into a text object.
- *
- * <p>The API provides backward compatibility to the Java and older ICU
- * CharacterIterator classes but extends them significantly:
- * <ol>
- * <li>CharacterIterator is now a subclass of ForwardCharacterIterator.</li>
- * <li>While the old API functions provided forward iteration with
- * "pre-increment" semantics, the new one also provides functions
- * with "post-increment" semantics. They are more efficient and should
- * be the preferred iterator functions for new implementations.
- * The backward iteration always had "pre-decrement" semantics, which
- * are efficient.</li>
- * <li>Just like ForwardCharacterIterator, it provides access to
- * both code units and code points. Code point access versions are available
- * for the old and the new iteration semantics.</li>
- * <li>There are new functions for setting and moving the current position
- * without returning a character, for efficiency.</li>
- * </ol>
- *
- * See ForwardCharacterIterator for examples for using the new forward iteration
- * functions. For backward iteration, there is also a hasPrevious() function
- * that can be used analogously to hasNext().
- * The old functions work as before and are shown below.</p>
- *
- * <p>Examples for some of the new functions:</p>
- *
- * Forward iteration with hasNext():
- * \code
- * void forward1(CharacterIterator &it) {
- * UChar32 c;
- * for(it.setToStart(); it.hasNext();) {
- * c=it.next32PostInc();
- * // use c
- * }
- * }
- * \endcode
- * Forward iteration more similar to loops with the old forward iteration,
- * showing a way to convert simple for() loops:
- * \code
- * void forward2(CharacterIterator &it) {
- * UChar c;
- * for(c=it.firstPostInc(); c!=CharacterIterator::DONE; c=it.nextPostInc()) {
- * // use c
- * }
- * }
- * \endcode
- * Backward iteration with setToEnd() and hasPrevious():
- * \code
- * void backward1(CharacterIterator &it) {
- * UChar32 c;
- * for(it.setToEnd(); it.hasPrevious();) {
- * c=it.previous32();
- * // use c
- * }
- * }
- * \endcode
- * Backward iteration with a more traditional for() loop:
- * \code
- * void backward2(CharacterIterator &it) {
- * UChar c;
- * for(c=it.last(); c!=CharacterIterator::DONE; c=it.previous()) {
- * // use c
- * }
- * }
- * \endcode
- *
- * Example for random access:
- * \code
- * void random(CharacterIterator &it) {
- * // set to the third code point from the beginning
- * it.move32(3, CharacterIterator::kStart);
- * // get a code point from here without moving the position
- * UChar32 c=it.current32();
- * // get the position
- * int32_t pos=it.getIndex();
- * // get the previous code unit
- * UChar u=it.previous();
- * // move back one more code unit
- * it.move(-1, CharacterIterator::kCurrent);
- * // set the position back to where it was
- * // and read the same code point c and move beyond it
- * it.setIndex(pos);
- * if(c!=it.next32PostInc()) {
- * exit(1); // CharacterIterator inconsistent
- * }
- * }
- * \endcode
- *
- * <p>Examples, especially for the old API:</p>
- *
- * Function processing characters, in this example simple output
- * <pre>
- * \code
- * void processChar( UChar c )
- * {
- * cout << " " << c;
- * }
- * \endcode
- * </pre>
- * Traverse the text from start to finish
- * <pre>
- * \code
- * void traverseForward(CharacterIterator& iter)
- * {
- * for(UChar c = iter.first(); c != CharacterIterator.DONE; c = iter.next()) {
- * processChar(c);
- * }
- * }
- * \endcode
- * </pre>
- * Traverse the text backwards, from end to start
- * <pre>
- * \code
- * void traverseBackward(CharacterIterator& iter)
- * {
- * for(UChar c = iter.last(); c != CharacterIterator.DONE; c = iter.previous()) {
- * processChar(c);
- * }
- * }
- * \endcode
- * </pre>
- * Traverse both forward and backward from a given position in the text.
- * Calls to notBoundary() in this example represents some additional stopping criteria.
- * <pre>
- * \code
- * void traverseOut(CharacterIterator& iter, int32_t pos)
- * {
- * UChar c;
- * for (c = iter.setIndex(pos);
- * c != CharacterIterator.DONE && (Unicode::isLetter(c) || Unicode::isDigit(c));
- * c = iter.next()) {}
- * int32_t end = iter.getIndex();
- * for (c = iter.setIndex(pos);
- * c != CharacterIterator.DONE && (Unicode::isLetter(c) || Unicode::isDigit(c));
- * c = iter.previous()) {}
- * int32_t start = iter.getIndex() + 1;
- *
- * cout << "start: " << start << " end: " << end << endl;
- * for (c = iter.setIndex(start); iter.getIndex() < end; c = iter.next() ) {
- * processChar(c);
- * }
- * }
- * \endcode
- * </pre>
- * Creating a StringCharacterIterator and calling the test functions
- * <pre>
- * \code
- * void CharacterIterator_Example( void )
- * {
- * cout << endl << "===== CharacterIterator_Example: =====" << endl;
- * UnicodeString text("Ein kleiner Satz.");
- * StringCharacterIterator iterator(text);
- * cout << "----- traverseForward: -----------" << endl;
- * traverseForward( iterator );
- * cout << endl << endl << "----- traverseBackward: ----------" << endl;
- * traverseBackward( iterator );
- * cout << endl << endl << "----- traverseOut: ---------------" << endl;
- * traverseOut( iterator, 7 );
- * cout << endl << endl << "-----" << endl;
- * }

+/**
+ * Abstract class that defines an API for forward-only iteration
+ * on text objects.
+ * This is a minimal interface for iteration without random access
+ * or backwards iteration. It is especially useful for wrapping
+ * streams with converters into an object for collation or
+ * normalization.
+ *
+ * <p>Characters can be accessed in two ways: as code units or as
+ * code points.
+ * Unicode code points are 21-bit integers and are the scalar values
+ * of Unicode characters. ICU uses the type UChar32 for them.
+ * Unicode code units are the storage units of a given
+ * Unicode/UCS Transformation Format (a character encoding scheme).
+ * With UTF-16, all code points can be represented with either one
+ * or two code units ("surrogates").
+ * String storage is typically based on code units, while properties
+ * of characters are typically determined using code point values.
+ * Some processes may be designed to work with sequences of code units,
+ * or it may be known that all characters that are important to an
+ * algorithm can be represented with single code units.
+ * Other processes will need to use the code point access functions.</p>
+ *
+ * <p>ForwardCharacterIterator provides nextPostInc() to access
+ * a code unit and advance an internal position into the text object,
+ * similar to a <code>return text[position++]</code>.<br>
+ * It provides next32PostInc() to access a code point and advance an internal
+ * position.</p>
+ *
+ * <p>next32PostInc() assumes that the current position is that of
+ * the beginning of a code point, i.e., of its first code unit.
+ * After next32PostInc(), this will be true again.
+ * In general, access to code units and code points in the same
+ * iteration loop should not be mixed. In UTF-16, if the current position
+ * is on a second code unit (Low Surrogate), then only that code unit
+ * is returned even by next32PostInc().</p>
+ *
+ * <p>For iteration with either function, there are two ways to
+ * check for the end of the iteration. When there are no more
+ * characters in the text object:
+ * <ul>
+ * <li>The hasNext() function returns FALSE.</li>
+ * <li>nextPostInc() and next32PostInc() return DONE
+ * when one attempts to read beyond the end of the text object.</li>
+ * </ul>
+ *
+ * Example:
+ * \code
+ * void function1(ForwardCharacterIterator &it) {
+ * UChar32 c;
+ * while(it.hasNext()) {
+ * c=it.next32PostInc();
+ * // use c
+ * }
+ * }
+ *
+ * void function1(ForwardCharacterIterator &it) {
+ * UChar c;
+ * while((c=it.nextPostInc())!=ForwardCharacterIterator::DONE) {
+ * // use c
+ * }
+ * }
+ * \endcode

+ * Abstract class that defines an API for iteration
+ * on text objects.
+ * This is an interface for forward and backward iteration
+ * and random access into a text object.
+ *
+ * <p>The API provides backward compatibility to the Java and older ICU
+ * CharacterIterator classes but extends them significantly:
+ * <ol>
+ * <li>CharacterIterator is now a subclass of ForwardCharacterIterator.</li>
+ * <li>While the old API functions provided forward iteration with
+ * "pre-increment" semantics, the new one also provides functions
+ * with "post-increment" semantics. They are more efficient and should
+ * be the preferred iterator functions for new implementations.
+ * The backward iteration always had "pre-decrement" semantics, which
+ * are efficient.</li>
+ * <li>Just like ForwardCharacterIterator, it provides access to
+ * both code units and code points. Code point access versions are available
+ * for the old and the new iteration semantics.</li>
+ * <li>There are new functions for setting and moving the current position
+ * without returning a character, for efficiency.</li>
+ * </ol>
+ *
+ * See ForwardCharacterIterator for examples for using the new forward iteration
+ * functions. For backward iteration, there is also a hasPrevious() function
+ * that can be used analogously to hasNext().
+ * The old functions work as before and are shown below.</p>
+ *
+ * <p>Examples for some of the new functions:</p>
+ *
+ * Forward iteration with hasNext():
+ * \code
+ * void forward1(CharacterIterator &it) {
+ * UChar32 c;
+ * for(it.setToStart(); it.hasNext();) {
+ * c=it.next32PostInc();
+ * // use c
+ * }
+ * }
+ * \endcode
+ * Forward iteration more similar to loops with the old forward iteration,
+ * showing a way to convert simple for() loops:
+ * \code
+ * void forward2(CharacterIterator &it) {
+ * UChar c;
+ * for(c=it.firstPostInc(); c!=CharacterIterator::DONE; c=it.nextPostInc()) {
+ * // use c
+ * }
+ * }
+ * \endcode
+ * Backward iteration with setToEnd() and hasPrevious():
+ * \code
+ * void backward1(CharacterIterator &it) {
+ * UChar32 c;
+ * for(it.setToEnd(); it.hasPrevious();) {
+ * c=it.previous32();
+ * // use c
+ * }
+ * }
+ * \endcode
+ * Backward iteration with a more traditional for() loop:
+ * \code
+ * void backward2(CharacterIterator &it) {
+ * UChar c;
+ * for(c=it.last(); c!=CharacterIterator::DONE; c=it.previous()) {
+ * // use c
+ * }
+ * }
+ * \endcode
+ *
+ * Example for random access:
+ * \code
+ * void random(CharacterIterator &it) {
+ * // set to the third code point from the beginning
+ * it.move32(3, CharacterIterator::kStart);
+ * // get a code point from here without moving the position
+ * UChar32 c=it.current32();
+ * // get the position
+ * int32_t pos=it.getIndex();
+ * // get the previous code unit
+ * UChar u=it.previous();
+ * // move back one more code unit
+ * it.move(-1, CharacterIterator::kCurrent);
+ * // set the position back to where it was
+ * // and read the same code point c and move beyond it
+ * it.setIndex(pos);
+ * if(c!=it.next32PostInc()) {
+ * exit(1); // CharacterIterator inconsistent
+ * }
+ * }
+ * \endcode
+ *
+ * <p>Examples, especially for the old API:</p>
+ *
+ * Function processing characters, in this example simple output
+ * <pre>
+ * \code
+ * void processChar( UChar c )
+ * {
+ * cout << " " << c;
+ * }
+ * \endcode
+ * </pre>
+ * Traverse the text from start to finish
+ * <pre>
+ * \code
+ * void traverseForward(CharacterIterator& iter)
+ * {
+ * for(UChar c = iter.first(); c != CharacterIterator.DONE; c = iter.next()) {
+ * processChar(c);
+ * }
+ * }
+ * \endcode
+ * </pre>
+ * Traverse the text backwards, from end to start
+ * <pre>
+ * \code
+ * void traverseBackward(CharacterIterator& iter)
+ * {
+ * for(UChar c = iter.last(); c != CharacterIterator.DONE; c = iter.previous()) {
+ * processChar(c);
+ * }
+ * }
+ * \endcode
+ * </pre>
+ * Traverse both forward and backward from a given position in the text.
+ * Calls to notBoundary() in this example represents some additional stopping criteria.
+ * <pre>
+ * \code
+ * void traverseOut(CharacterIterator& iter, int32_t pos)
+ * {
+ * UChar c;
+ * for (c = iter.setIndex(pos);
+ * c != CharacterIterator.DONE && (Unicode::isLetter(c) || Unicode::isDigit(c));
+ * c = iter.next()) {}
+ * int32_t end = iter.getIndex();
+ * for (c = iter.setIndex(pos);
+ * c != CharacterIterator.DONE && (Unicode::isLetter(c) || Unicode::isDigit(c));
+ * c = iter.previous()) {}
+ * int32_t start = iter.getIndex() + 1;
+ *
+ * cout << "start: " << start << " end: " << end << endl;
+ * for (c = iter.setIndex(start); iter.getIndex() < end; c = iter.next() ) {
+ * processChar(c);
+ * }
+ * }
+ * \endcode
+ * </pre>
+ * Creating a StringCharacterIterator and calling the test functions
+ * <pre>
+ * \code
+ * void CharacterIterator_Example( void )
+ * {
+ * cout << endl << "===== CharacterIterator_Example: =====" << endl;
+ * UnicodeString text("Ein kleiner Satz.");
+ * StringCharacterIterator iterator(text);
+ * cout << "----- traverseForward: -----------" << endl;

-/**
- * ChoiceFormat converts between ranges of numeric values
- * and string names for those ranges. A <code>ChoiceFormat</code> splits
- * the real number line <code>-Inf</code> to <code>+Inf</code> into two
- * or more contiguous ranges. Each range is mapped to a
- * string. <code>ChoiceFormat</code> is generally used in a
- * <code>MessageFormat</code> for displaying grammatically correct
- * plurals such as "There are 2 files."</p>
- *
- * <p>There are two methods of defining a <code>ChoiceFormat</code>; both
- * are equivalent. The first is by using a string pattern. This is the
- * preferred method in most cases. The second method is through direct
- * specification of the arrays that make up the
- * <code>ChoiceFormat</code>.</p>
- *
- * <p><strong>Patterns</strong></p>
- *
- * <p>In most cases, the preferred way to define a
- * <code>ChoiceFormat</code> is with a pattern. Here is an example of a
- * <code>ChoiceFormat</code> pattern:</p>
- *
- * \htmlonly<pre> 0≤are no files|1≤is one file|1<are many files</pre>\endhtmlonly
- *
- * <p>or equivalently,</p>
- *
- * \htmlonly<pre> 0#are no files|1#is one file|1<are many files</pre>\endhtmlonly
- *
- * <p>The pattern consists of a number or <em>range specifiers</em>
- * separated by vertical bars '|' (U+007C). There is no
- * vertical bar after the last range. Each range specifier is of the
- * form:</p>
- *
- * \htmlonly<blockquote><em>Number Separator String</em></blockquote>\endhtmlonly
- *
- * <p><em>Number</em> is a floating point number that can be parsed by a
- * default <code>NumberFormat</code> for the US locale. It gives the
- * lower limit of this range. The lower limit is either inclusive or
- * exclusive, depending on the <em>separator</em>. The upper limit is
- * given by the lower limit of the next range. The Unicode infinity
- * sign \htmlonly∞ \endhtmlonly (U+221E) is recognized for positive infinity. It may be preceded by
- * '-' (U+002D) to indicate negative infinity.</p>
- *
- * <p><em>String</em> is the format string for this range, with special
- * characters enclosed in single quotes (<code>'The #
- * sign'</code>). Single quotes themselves are indicated by two single
- * quotes in a row (<code>'o''clock'</code>).</p>
- *
- * <p><em>Separator</em> is one of the following single characters:
- *
- * <ul>
- * <li>\htmlonly'≤' \endhtmlonly (U+2264) or '#' (U+0023)
- * indicates that the lower limit given by <em>Number</em> is
- * inclusive. (The two characters are equivalent to ChoiceFormat.)
- * This means that the limit value <em>Number</em> belongs to this
- * range. Another way of saying this is that the corresponding
- * closure is <code>FALSE</code>.</li>
- *
- * <li>'<' (U+003C) indicates that the lower limit given by
- * <em>Number</em> is exclusive. This means that the value
- * <em>Number</em> belongs to the prior range.</li> Another way of
- * saying this is that the corresponding closure is
- * <code>TRUE</code>.
- * </ul>
- *
- * <p>See below for more information about closures.</p>
- *
- * <p><strong>Arrays</strong></p>
- *
- * <p>A <code>ChoiceFormat</code> defining <code>n</code> intervals
- * (<code>n</code> >= 2) is specified by three arrays of
- * <code>n</code> items:
- *
- * <ul>
- * <li><code>double limits[]</code> gives the start of each
- * interval. This must be a non-decreasing list of values, none of
- * which may be <code>NaN</code>.</li>
- * <li><code>UBool closures[]</code> determines whether each limit
- * value is contained in the interval below it or in the interval
- * above it. If <code>closures[i]</code> is <code>FALSE</code>, then
- * <code>limits[i]</code> is a member of interval
- * <code>i</code>. Otherwise it is a member of interval
- * <code>i+1</code>. If no closures array is specified, this is
- * equivalent to having all closures be <code>FALSE</code>. Closures
- * allow one to specify half-open, open, or closed intervals.</li>
- * <li><code>UnicodeString formats[]</code> gives the string label
- * associated with each interval.</li>
- * </ul>
- *
- * <p><strong>Formatting and Parsing</strong></p>
- *
- * <p>During formatting, a number is converted to a
- * string. <code>ChoiceFormat</code> accomplishes this by mapping the
- * number to an interval using the following rule. Given a number
- * <code>X</code> and and index value <code>j</code> in the range
- * <code>0..n-1</code>, where <code>n</code> is the number of ranges:</p>
- *
- * \htmlonly<blockquote>\endhtmlonly<code>X</code> matches <code>j</code> if and only if
- * <code>limit[j] <= X < limit[j+1]</code>
- * \htmlonly</blockquote>\endhtmlonly
- *
- * <p>(This assumes that all closures are <code>FALSE</code>. If some
- * closures are <code>TRUE</code> then the relations must be changed to
- * <code><=</code> or <code><</code> as appropriate.) If there is
- * no match, then either the first or last index is used, depending on
- * whether the number is too low or too high. Once a number is mapped to
- * an interval <code>j</code>, the string <code>formats[j]</code> is
- * output.</p>
- *
- * <p>During parsing, a string is converted to a
- * number. <code>ChoiceFormat</code> finds the element
- * <code>formats[j]</code> equal to the string, and returns
- * <code>limits[j]</code> as the parsed value.</p>
- *
- * <p><strong>Notes</strong></p>
- *
- * <p>The first limit value does not define a range boundary. For
- * example, in the pattern \htmlonly"<code>1.0#a|2.0#b</code>"\endhtmlonly, the
- * intervals are [-Inf, 2.0) and [2.0, +Inf]. It appears that the first
- * interval should be [1.0, 2.0). However, since all values that are too
- * small are mapped to range zero, the first interval is effectively
- * [-Inf, 2.0). However, the first limit value <em>is</em> used during
- * formatting. In this example, <code>parse("a")</code> returns
- * 1.0.</p>
- *
- * <p>There are no gaps between intervals and the entire number line is
- * covered. A <code>ChoiceFormat</code> maps <em>all</em> possible
- * double values to a finite set of intervals.</p>
- *
- * <p>The non-number <code>NaN</code> is mapped to interval zero during
- * formatting.</p>
- *
- * <p><strong>Examples</strong></p>
- *
- * <p>Here is an example of two arrays that map the number
- * <code>1..7</code> to the English day of the week abbreviations
- * <code>Sun..Sat</code>. No closures array is given; this is the same as
- * specifying all closures to be <code>FALSE</code>.</p>
- *
- * <pre> {1,2,3,4,5,6,7},
- * {"Sun","Mon","Tue","Wed","Thur","Fri","Sat"}</pre>
- *
- * <p>Here is an example that maps the ranges [-Inf, 1), [1, 1], and (1,
- * +Inf] to three strings. That is, the number line is split into three
- * ranges: x < 1.0, x = 1.0, and x > 1.0.</p>
- *
- * <pre> {0, 1, 1},
- * {FALSE, FALSE, TRUE},
- * {"no files", "one file", "many files"}</pre>
- *
- * <p>Here is a simple example that shows formatting and parsing: </p>
- *
- * \code
- * #include <unicode/choicfmt.h>
- * #include <unicode/unistr.h>
- * #include <iostream.h>
- *
- * int main(int argc, char *argv[]) {
- * double limits[] = {1,2,3,4,5,6,7};
- * UnicodeString monthNames[] = {
- * "Sun","Mon","Tue","Wed","Thu","Fri","Sat"};
- * ChoiceFormat fmt(limits, monthNames, 7);
- * UnicodeString str;
- * char buf[256];
- * for (double x = 1.0; x <= 8.0; x += 1.0) {
- * fmt.format(x, str);
- * str.extract(0, str.length(), buf, 256, "");
- * str.truncate(0);
- * cout << x << " -> "
- * << buf << endl;
- * }
- * cout << endl;
- * return 0;
- * }
- * \endcode
- *
- * <p>Here is a more complex example using a <code>ChoiceFormat</code>
- * constructed from a pattern together with a
- * <code>MessageFormat</code>.</p>
- *
- * \code
- * #include <unicode/choicfmt.h>
- * #include <unicode/msgfmt.h>
- * #include <unicode/unistr.h>
- * #include <iostream.h>
- *
- * int main(int argc, char *argv[]) {
- * UErrorCode status = U_ZERO_ERROR;
- * double filelimits[] = {0,1,2};
- * UnicodeString filepart[] =
- * {"are no files","is one file","are {0} files"};
- * ChoiceFormat* fileform = new ChoiceFormat(filelimits, filepart, 3 );
- * Format* testFormats[] =
- * {fileform, NULL, NumberFormat::createInstance(status)};
- * MessageFormat pattform("There {0} on {1}", status );
- * pattform.adoptFormats(testFormats, 3);
- * Formattable testArgs[] = {0L, "Disk A"};
- * FieldPosition fp(0);
- * UnicodeString str;
- * char buf[256];
- * for (int32_t i = 0; i < 4; ++i) {
- * Formattable fInt(i);
- * testArgs[0] = fInt;
- * pattform.format(testArgs, 2, str, fp, status );
- * str.extract(0, str.length(), buf, "");
- * str.truncate(0);
- * cout << "Output for i=" << i << " : " << buf << endl;
- * }
- * cout << endl;
- * return 0;
- * }
- * \endcode
- *
- * <p><em>User subclasses are not supported.</em> While clients may write
- * subclasses, such code will not necessarily work and will not be
- * guaranteed to work stably from release to release.

+/**
+ * ChoiceFormat converts between ranges of numeric values
+ * and string names for those ranges. A <code>ChoiceFormat</code> splits
+ * the real number line <code>-Inf</code> to <code>+Inf</code> into two
+ * or more contiguous ranges. Each range is mapped to a
+ * string. <code>ChoiceFormat</code> is generally used in a
+ * <code>MessageFormat</code> for displaying grammatically correct
+ * plurals such as "There are 2 files."</p>
+ *
+ * <p>There are two methods of defining a <code>ChoiceFormat</code>; both
+ * are equivalent. The first is by using a string pattern. This is the
+ * preferred method in most cases. The second method is through direct
+ * specification of the arrays that make up the
+ * <code>ChoiceFormat</code>.</p>
+ *
+ * <p><strong>Patterns</strong></p>
+ *
+ * <p>In most cases, the preferred way to define a
+ * <code>ChoiceFormat</code> is with a pattern. Here is an example of a
+ * <code>ChoiceFormat</code> pattern:</p>
+ *
+ * \htmlonly<pre> 0≤are no files|1≤is one file|1<are many files</pre>\endhtmlonly
+ *
+ * <p>or equivalently,</p>
+ *
+ * \htmlonly<pre> 0#are no files|1#is one file|1<are many files</pre>\endhtmlonly
+ *
+ * <p>The pattern consists of a number or <em>range specifiers</em>
+ * separated by vertical bars '|' (U+007C). There is no
+ * vertical bar after the last range. Each range specifier is of the
+ * form:</p>
+ *
+ * \htmlonly<blockquote><em>Number Separator String</em></blockquote>\endhtmlonly
+ *
+ * <p><em>Number</em> is a floating point number that can be parsed by a
+ * default <code>NumberFormat</code> for the US locale. It gives the
+ * lower limit of this range. The lower limit is either inclusive or
+ * exclusive, depending on the <em>separator</em>. The upper limit is
+ * given by the lower limit of the next range. The Unicode infinity
+ * sign \htmlonly∞ \endhtmlonly (U+221E) is recognized for positive infinity. It may be preceded by
+ * '-' (U+002D) to indicate negative infinity.</p>
+ *
+ * <p><em>String</em> is the format string for this range, with special
+ * characters enclosed in single quotes (<code>'The #
+ * sign'</code>). Single quotes themselves are indicated by two single
+ * quotes in a row (<code>'o''clock'</code>).</p>
+ *
+ * <p><em>Separator</em> is one of the following single characters:
+ *
+ * <ul>
+ * <li>\htmlonly'≤' \endhtmlonly (U+2264) or '#' (U+0023)
+ * indicates that the lower limit given by <em>Number</em> is
+ * inclusive. (The two characters are equivalent to ChoiceFormat.)
+ * This means that the limit value <em>Number</em> belongs to this
+ * range. Another way of saying this is that the corresponding
+ * closure is <code>FALSE</code>.</li>
+ *
+ * <li>'<' (U+003C) indicates that the lower limit given by
+ * <em>Number</em> is exclusive. This means that the value
+ * <em>Number</em> belongs to the prior range.</li> Another way of
+ * saying this is that the corresponding closure is
+ * <code>TRUE</code>.
+ * </ul>
+ *
+ * <p>See below for more information about closures.</p>
+ *
+ * <p><strong>Arrays</strong></p>
+ *
+ * <p>A <code>ChoiceFormat</code> defining <code>n</code> intervals
+ * (<code>n</code> >= 2) is specified by three arrays of
+ * <code>n</code> items:
+ *
+ * <ul>
+ * <li><code>double limits[]</code> gives the start of each
+ * interval. This must be a non-decreasing list of values, none of
+ * which may be <code>NaN</code>.</li>
+ * <li><code>UBool closures[]</code> determines whether each limit
+ * value is contained in the interval below it or in the interval
+ * above it. If <code>closures[i]</code> is <code>FALSE</code>, then
+ * <code>limits[i]</code> is a member of interval
+ * <code>i</code>. Otherwise it is a member of interval
+ * <code>i+1</code>. If no closures array is specified, this is
+ * equivalent to having all closures be <code>FALSE</code>. Closures
+ * allow one to specify half-open, open, or closed intervals.</li>
+ * <li><code>UnicodeString formats[]</code> gives the string label
+ * associated with each interval.</li>
+ * </ul>
+ *
+ * <p><strong>Formatting and Parsing</strong></p>
+ *
+ * <p>During formatting, a number is converted to a
+ * string. <code>ChoiceFormat</code> accomplishes this by mapping the
+ * number to an interval using the following rule. Given a number
+ * <code>X</code> and and index value <code>j</code> in the range
+ * <code>0..n-1</code>, where <code>n</code> is the number of ranges:</p>
+ *
+ * \htmlonly<blockquote>\endhtmlonly<code>X</code> matches <code>j</code> if and only if
+ * <code>limit[j] <= X < limit[j+1]</code>
+ * \htmlonly</blockquote>\endhtmlonly
+ *
+ * <p>(This assumes that all closures are <code>FALSE</code>. If some
+ * closures are <code>TRUE</code> then the relations must be changed to
+ * <code><=</code> or <code><</code> as appropriate.) If there is
+ * no match, then either the first or last index is used, depending on
+ * whether the number is too low or too high. Once a number is mapped to
+ * an interval <code>j</code>, the string <code>formats[j]</code> is
+ * output.</p>
+ *
+ * <p>During parsing, a string is converted to a
+ * number. <code>ChoiceFormat</code> finds the element
+ * <code>formats[j]</code> equal to the string, and returns
+ * <code>limits[j]</code> as the parsed value.</p>
+ *
+ * <p><strong>Notes</strong></p>
+ *
+ * <p>The first limit value does not define a range boundary. For
+ * example, in the pattern \htmlonly"<code>1.0#a|2.0#b</code>"\endhtmlonly, the
+ * intervals are [-Inf, 2.0) and [2.0, +Inf]. It appears that the first
+ * interval should be [1.0, 2.0). However, since all values that are too
+ * small are mapped to range zero, the first interval is effectively
+ * [-Inf, 2.0). However, the first limit value <em>is</em> used during
+ * formatting. In this example, <code>parse("a")</code> returns
+ * 1.0.</p>
+ *
+ * <p>There are no gaps between intervals and the entire number line is
+ * covered. A <code>ChoiceFormat</code> maps <em>all</em> possible
+ * double values to a finite set of intervals.</p>
+ *
+ * <p>The non-number <code>NaN</code> is mapped to interval zero during
+ * formatting.</p>
+ *
+ * <p><strong>Examples</strong></p>
+ *
+ * <p>Here is an example of two arrays that map the number
+ * <code>1..7</code> to the English day of the week abbreviations
+ * <code>Sun..Sat</code>. No closures array is given; this is the same as
+ * specifying all closures to be <code>FALSE</code>.</p>
+ *
+ * <pre> {1,2,3,4,5,6,7},
+ * {"Sun","Mon","Tue","Wed","Thur","Fri","Sat"}</pre>
+ *
+ * <p>Here is an example that maps the ranges [-Inf, 1), [1, 1], and (1,
+ * +Inf] to three strings. That is, the number line is split into three
+ * ranges: x < 1.0, x = 1.0, and x > 1.0.</p>
+ *
+ * <pre> {0, 1, 1},
+ * {FALSE, FALSE, TRUE},
+ * {"no files", "one file", "many files"}</pre>
+ *
+ * <p>Here is a simple example that shows formatting and parsing: </p>
+ *
+ * \code
+ * #include <unicode/choicfmt.h>
+ * #include <unicode/unistr.h>
+ * #include <iostream.h>
+ *
+ * int main(int argc, char *argv[]) {
+ * double limits[] = {1,2,3,4,5,6,7};
+ * UnicodeString monthNames[] = {
+ * "Sun","Mon","Tue","Wed","Thu","Fri","Sat"};
+ * ChoiceFormat fmt(limits, monthNames, 7);
+ * UnicodeString str;
+ * char buf[256];
+ * for (double x = 1.0; x <= 8.0; x += 1.0) {
+ * fmt.format(x, str);
+ * str.extract(0, str.length(), buf, 256, "");
+ * str.truncate(0);
+ * cout << x << " -> "
+ * << buf << endl;
+ * }
+ * cout << endl;
+ * return 0;
+ * }
+ * \endcode
+ *
+ * <p>Here is a more complex example using a <code>ChoiceFormat</code>
+ * constructed from a pattern together with a
+ * <code>MessageFormat</code>.</p>
+ *
+ * \code
+ * #include <unicode/choicfmt.h>
+ * #include <unicode/msgfmt.h>
+ * #include <unicode/unistr.h>
+ * #include <iostream.h>
+ *
+ * int main(int argc, char *argv[]) {
+ * UErrorCode status = U_ZERO_ERROR;
+ * double filelimits[] = {0,1,2};
+ * UnicodeString filepart[] =
+ * {"are no files","is one file","are {0} files"};
+ * ChoiceFormat* fileform = new ChoiceFormat(filelimits, filepart, 3 );
+ * Format* testFormats[] =
+ * {fileform, NULL, NumberFormat::createInstance(status)};
+ * MessageFormat pattform("There {0} on {1}", status );
+ * pattform.adoptFormats(testFormats, 3);
+ * Formattable testArgs[] = {0L, "Disk A"};
+ * FieldPosition fp(0);
+ * UnicodeString str;
+ * char buf[256];
+ * for (int32_t i = 0; i < 4; ++i) {
+ * Formattable fInt(i);
+ * testArgs[0] = fInt;
+ * pattform.format(testArgs, 2, str, fp, status );
+ * str.extract(0, str.length(), buf, "");
+ * str.truncate(0);
+ * cout << "Output for i=" << i << " : " << buf << endl;
+ * }

-/**
-* The CollationElementIterator class is used as an iterator to walk through
-* each character of an international string. Use the iterator to return the
-* ordering priority of the positioned character. The ordering priority of a
-* character, which we refer to as a key, defines how a character is collated in
-* the given collation object.
-* For example, consider the following in Spanish:
-* <pre>
-* "ca" -> the first key is key('c') and second key is key('a').
-* "cha" -> the first key is key('ch') and second key is key('a').</pre>
-* And in German,
-* <pre> \htmlonly "æb"-> the first key is key('a'), the second key is key('e'), and
-* the third key is key('b'). \endhtmlonly </pre>
-* The key of a character, is an integer composed of primary order(short),
-* secondary order(char), and tertiary order(char). Java strictly defines the
-* size and signedness of its primitive data types. Therefore, the static
-* functions primaryOrder(), secondaryOrder(), and tertiaryOrder() return
-* int32_t to ensure the correctness of the key value.
-* <p>Example of the iterator usage: (without error checking)
-* <pre>
-* \code
-* void CollationElementIterator_Example()
-* {
-* UnicodeString str = "This is a test";
-* UErrorCode success = U_ZERO_ERROR;
-* RuleBasedCollator* rbc =
-* (RuleBasedCollator*) RuleBasedCollator::createInstance(success);
-* CollationElementIterator* c =
-* rbc->createCollationElementIterator( str );
-* int32_t order = c->next(success);
-* c->reset();
-* order = c->previous(success);
-* delete c;
-* delete rbc;
-* }
-* \endcode
-* </pre>
-* <p>
-* CollationElementIterator::next returns the collation order of the next
-* character based on the comparison level of the collator.
-* CollationElementIterator::previous returns the collation order of the
-* previous character based on the comparison level of the collator.
-* The Collation Element Iterator moves only in one direction between calls to
-* CollationElementIterator::reset. That is, CollationElementIterator::next()
-* and CollationElementIterator::previous can not be inter-used. Whenever

+
+/**
+* The CollationElementIterator class is used as an iterator to walk through
+* each character of an international string. Use the iterator to return the
+* ordering priority of the positioned character. The ordering priority of a
+* character, which we refer to as a key, defines how a character is collated in
+* the given collation object.
+* For example, consider the following in Spanish:
+* <pre>
+* "ca" -> the first key is key('c') and second key is key('a').
+* "cha" -> the first key is key('ch') and second key is key('a').</pre>
+* And in German,
+* <pre> \htmlonly "æb"-> the first key is key('a'), the second key is key('e'), and
+* the third key is key('b'). \endhtmlonly </pre>
+* The key of a character, is an integer composed of primary order(short),
+* secondary order(char), and tertiary order(char). Java strictly defines the
+* size and signedness of its primitive data types. Therefore, the static
+* functions primaryOrder(), secondaryOrder(), and tertiaryOrder() return
+* int32_t to ensure the correctness of the key value.
+* <p>Example of the iterator usage: (without error checking)
+* <pre>
+* \code
+* void CollationElementIterator_Example()
+* {
+* UnicodeString str = "This is a test";
+* UErrorCode success = U_ZERO_ERROR;
+* RuleBasedCollator* rbc =
+* (RuleBasedCollator*) RuleBasedCollator::createInstance(success);
+* CollationElementIterator* c =
+* rbc->createCollationElementIterator( str );
+* int32_t order = c->next(success);
+* c->reset();
+* order = c->previous(success);
+* delete c;
+* delete rbc;
+* }
+* \endcode
+* </pre>
+* <p>
+* CollationElementIterator::next returns the collation order of the next
+* character based on the comparison level of the collator.
+* CollationElementIterator::previous returns the collation order of the
+* previous character based on the comparison level of the collator.
+* The Collation Element Iterator moves only in one direction between calls to
+* CollationElementIterator::reset. That is, CollationElementIterator::next()
+* and CollationElementIterator::previous can not be inter-used. Whenever
+* CollationElementIterator::previous is to be called after
+* CollationElementIterator::next() or vice versa,
+* CollationElementIterator::reset has to be called first to reset the status,
+* shifting pointers to either the end or the start of the string. Hence at the
+* next call of CollationElementIterator::previous or
+* CollationElementIterator::next(), the first or last collation order will be
+* returned.
+* If a change of direction is done without a CollationElementIterator::reset(),
+* the result is undefined.
+* The result of a forward iterate (CollationElementIterator::next) and
+* reversed result of the backward iterate (CollationElementIterator::previous)
+* on the same string are equivalent, if collation orders with the value
+* UCOL_IGNORABLE are ignored.
+* Character based on the comparison level of the collator. A collation order
+* consists of primary order, secondary order and tertiary order. The data

-
-/**
-* The <code>Collator</code> class performs locale-sensitive string
-* comparison.<br>
-* You use this class to build searching and sorting routines for natural
-* language text.<br>
-* <em>Important: </em>The ICU collation service has been reimplemented
-* in order to achieve better performance and UCA compliance.
-* For details, see the
-* <a href="http://source.icu-project.org/repos/icu/icuhtml/trunk/design/collation/ICU_collation_design.htm">
-* collation design document</a>.
-* <p>
-* <code>Collator</code> is an abstract base class. Subclasses implement
-* specific collation strategies. One subclass,
-* <code>RuleBasedCollator</code>, is currently provided and is applicable
-* to a wide set of languages. Other subclasses may be created to handle more
-* specialized needs.
-* <p>
-* Like other locale-sensitive classes, you can use the static factory method,
-* <code>createInstance</code>, to obtain the appropriate
-* <code>Collator</code> object for a given locale. You will only need to
-* look at the subclasses of <code>Collator</code> if you need to
-* understand the details of a particular collation strategy or if you need to
-* modify that strategy.
-* <p>
-* The following example shows how to compare two strings using the
-* <code>Collator</code> for the default locale.
-* \htmlonly<blockquote>\endhtmlonly
-* <pre>
-* \code
-* // Compare two strings in the default locale
-* UErrorCode success = U_ZERO_ERROR;
-* Collator* myCollator = Collator::createInstance(success);
-* if (myCollator->compare("abc", "ABC") < 0)
-* cout << "abc is less than ABC" << endl;
-* else
-* cout << "abc is greater than or equal to ABC" << endl;
-* \endcode
-* </pre>
-* \htmlonly</blockquote>\endhtmlonly
-* <p>
-* You can set a <code>Collator</code>'s <em>strength</em> property to
-* determine the level of difference considered significant in comparisons.
-* Five strengths are provided: <code>PRIMARY</code>, <code>SECONDARY</code>,
-* <code>TERTIARY</code>, <code>QUATERNARY</code> and <code>IDENTICAL</code>.
-* The exact assignment of strengths to language features is locale dependant.
-* For example, in Czech, "e" and "f" are considered primary differences,
-* while "e" and "\u00EA" are secondary differences, "e" and "E" are tertiary
-* differences and "e" and "e" are identical. The following shows how both case
-* and accents could be ignored for US English.
-* \htmlonly<blockquote>\endhtmlonly
-* <pre>
-* \code
-* //Get the Collator for US English and set its strength to PRIMARY
-* UErrorCode success = U_ZERO_ERROR;
-* Collator* usCollator = Collator::createInstance(Locale::US, success);
-* usCollator->setStrength(Collator::PRIMARY);
-* if (usCollator->compare("abc", "ABC") == 0)
-* cout << "'abc' and 'ABC' strings are equivalent with strength PRIMARY" << endl;
-* \endcode
-* </pre>
-* \htmlonly</blockquote>\endhtmlonly
-* <p>
-* For comparing strings exactly once, the <code>compare</code> method
-* provides the best performance. When sorting a list of strings however, it
-* is generally necessary to compare each string multiple times. In this case,
-* sort keys provide better performance. The <code>getSortKey</code> methods
-* convert a string to a series of bytes that can be compared bitwise against
-* other sort keys using <code>strcmp()</code>. Sort keys are written as
-* zero-terminated byte strings. They consist of several substrings, one for
-* each collation strength level, that are delimited by 0x01 bytes.
-* If the string code points are appended for UCOL_IDENTICAL, then they are
-* processed for correct code point order comparison and may contain 0x01
-* bytes but not zero bytes.
-* </p>
-* <p>
-* An older set of APIs returns a <code>CollationKey</code> object that wraps
-* the sort key bytes instead of returning the bytes themselves.
-* Its use is deprecated, but it is still available for compatibility with
-* Java.
-* </p>
-* <p>
-* <strong>Note:</strong> <code>Collator</code>s with different Locale,
-* and CollationStrength settings will return different sort
-* orders for the same set of strings. Locales have specific collation rules,
-* and the way in which secondary and tertiary differences are taken into
-* account, for example, will result in a different sorting order for same
-* strings.

+/**
+* The <code>Collator</code> class performs locale-sensitive string
+* comparison.<br>
+* You use this class to build searching and sorting routines for natural
+* language text.<br>
+* <em>Important: </em>The ICU collation service has been reimplemented
+* in order to achieve better performance and UCA compliance.
+* For details, see the
+* <a href="http://source.icu-project.org/repos/icu/icuhtml/trunk/design/collation/ICU_collation_design.htm">
+* collation design document</a>.
+* <p>
+* <code>Collator</code> is an abstract base class. Subclasses implement
+* specific collation strategies. One subclass,
+* <code>RuleBasedCollator</code>, is currently provided and is applicable
+* to a wide set of languages. Other subclasses may be created to handle more
+* specialized needs.
+* <p>
+* Like other locale-sensitive classes, you can use the static factory method,
+* <code>createInstance</code>, to obtain the appropriate
+* <code>Collator</code> object for a given locale. You will only need to
+* look at the subclasses of <code>Collator</code> if you need to
+* understand the details of a particular collation strategy or if you need to
+* modify that strategy.
+* <p>
+* The following example shows how to compare two strings using the
+* <code>Collator</code> for the default locale.
+* \htmlonly<blockquote>\endhtmlonly
+* <pre>
+* \code
+* // Compare two strings in the default locale
+* UErrorCode success = U_ZERO_ERROR;
+* Collator* myCollator = Collator::createInstance(success);
+* if (myCollator->compare("abc", "ABC") < 0)
+* cout << "abc is less than ABC" << endl;
+* else
+* cout << "abc is greater than or equal to ABC" << endl;
+* \endcode
+* </pre>
+* \htmlonly</blockquote>\endhtmlonly
+* <p>
+* You can set a <code>Collator</code>'s <em>strength</em> property to
+* determine the level of difference considered significant in comparisons.
+* Five strengths are provided: <code>PRIMARY</code>, <code>SECONDARY</code>,
+* <code>TERTIARY</code>, <code>QUATERNARY</code> and <code>IDENTICAL</code>.
+* The exact assignment of strengths to language features is locale dependant.
+* For example, in Czech, "e" and "f" are considered primary differences,
+* while "e" and "\u00EA" are secondary differences, "e" and "E" are tertiary
+* differences and "e" and "e" are identical. The following shows how both case
+* and accents could be ignored for US English.
+* \htmlonly<blockquote>\endhtmlonly
+* <pre>
+* \code
+* //Get the Collator for US English and set its strength to PRIMARY
+* UErrorCode success = U_ZERO_ERROR;
+* Collator* usCollator = Collator::createInstance(Locale::US, success);
+* usCollator->setStrength(Collator::PRIMARY);
+* if (usCollator->compare("abc", "ABC") == 0)
+* cout << "'abc' and 'ABC' strings are equivalent with strength PRIMARY" << endl;
+* \endcode
+* </pre>
+* \htmlonly</blockquote>\endhtmlonly
+* <p>
+* For comparing strings exactly once, the <code>compare</code> method
+* provides the best performance. When sorting a list of strings however, it
+* is generally necessary to compare each string multiple times. In this case,
+* sort keys provide better performance. The <code>getSortKey</code> methods
+* convert a string to a series of bytes that can be compared bitwise against
+* other sort keys using <code>strcmp()</code>. Sort keys are written as
+* zero-terminated byte strings. They consist of several substrings, one for
+* each collation strength level, that are delimited by 0x01 bytes.
+* If the string code points are appended for UCOL_IDENTICAL, then they are
+* processed for correct code point order comparison and may contain 0x01
+* bytes but not zero bytes.
+* </p>
+* <p>
+* An older set of APIs returns a <code>CollationKey</code> object that wraps
+* the sort key bytes instead of returning the bytes themselves.
+* Its use is deprecated, but it is still available for compatibility with
+* Java.
+* </p>
+* <p>
+* <strong>Note:</strong> <code>Collator</code>s with different Locale,
+* and CollationStrength settings will return different sort
+* orders for the same set of strings. Locales have specific collation rules,
+* and the way in which secondary and tertiary differences are taken into
+* account, for example, will result in a different sorting order for same
+* strings.
+* </p>

-/**
- * DateFormat is an abstract class for a family of classes that convert dates and
- * times from their internal representations to textual form and back again in a
- * language-independent manner. Converting from the internal representation (milliseconds
- * since midnight, January 1, 1970) to text is known as "formatting," and converting
- * from text to millis is known as "parsing." We currently define only one concrete
- * subclass of DateFormat: SimpleDateFormat, which can handle pretty much all normal
- * date formatting and parsing actions.
- * <P>
- * DateFormat helps you to format and parse dates for any locale. Your code can
- * be completely independent of the locale conventions for months, days of the
- * week, or even the calendar format: lunar vs. solar.
- * <P>
- * To format a date for the current Locale, use one of the static factory
- * methods:
- * <pre>
- * \code
- * DateFormat* dfmt = DateFormat::createDateInstance();
- * UDate myDate = Calendar::getNow();
- * UnicodeString myString;
- * myString = dfmt->format( myDate, myString );
- * \endcode
- * </pre>
- * If you are formatting multiple numbers, it is more efficient to get the
- * format and use it multiple times so that the system doesn't have to fetch the
- * information about the local language and country conventions multiple times.
- * <pre>
- * \code
- * DateFormat* df = DateFormat::createDateInstance();
- * UnicodeString myString;
- * UDate myDateArr[] = { 0.0, 100000000.0, 2000000000.0 }; // test values
- * for (int32_t i = 0; i < 3; ++i) {
- * myString.remove();
- * cout << df->format( myDateArr[i], myString ) << endl;
- * }
- * \endcode
- * </pre>
- * To get specific fields of a date, you can use UFieldPosition to
- * get specific fields.
- * <pre>
- * \code
- * DateFormat* dfmt = DateFormat::createDateInstance();
- * FieldPosition pos(DateFormat::YEAR_FIELD);
- * UnicodeString myString;
- * myString = dfmt->format( myDate, myString );
- * cout << myString << endl;
- * cout << pos.getBeginIndex() << "," << pos. getEndIndex() << endl;
- * \endcode
- * </pre>
- * To format a date for a different Locale, specify it in the call to
- * createDateInstance().
- * <pre>
- * \code
- * DateFormat* df =
- * DateFormat::createDateInstance( DateFormat::SHORT, Locale::getFrance());
- * \endcode
- * </pre>
- * You can use a DateFormat to parse also.
- * <pre>
- * \code
- * UErrorCode status = U_ZERO_ERROR;
- * UDate myDate = df->parse(myString, status);
- * \endcode
- * </pre>
- * Use createDateInstance() to produce the normal date format for that country.
- * There are other static factory methods available. Use createTimeInstance()
- * to produce the normal time format for that country. Use createDateTimeInstance()
- * to produce a DateFormat that formats both date and time. You can pass in
- * different options to these factory methods to control the length of the
- * result; from SHORT to MEDIUM to LONG to FULL. The exact result depends on the
- * locale, but generally:
- * <ul type=round>
- * <li> SHORT is completely numeric, such as 12/13/52 or 3:30pm
- * <li> MEDIUM is longer, such as Jan 12, 1952
- * <li> LONG is longer, such as January 12, 1952 or 3:30:32pm
- * <li> FULL is pretty completely specified, such as
- * Tuesday, April 12, 1952 AD or 3:30:42pm PST.
- * </ul>
- * You can also set the time zone on the format if you wish. If you want even
- * more control over the format or parsing, (or want to give your users more
- * control), you can try casting the DateFormat you get from the factory methods
- * to a SimpleDateFormat. This will work for the majority of countries; just
- * remember to chck getDynamicClassID() before carrying out the cast.
- * <P>
- * You can also use forms of the parse and format methods with ParsePosition and
- * FieldPosition to allow you to
- * <ul type=round>
- * <li> Progressively parse through pieces of a string.
- * <li> Align any particular field, or find out where it is for selection
- * on the screen.
- * </ul>
- *
- * <p><em>User subclasses are not supported.</em> While clients may write
- * subclasses, such code will not necessarily work and will not be
- * guaranteed to work stably from release to release.

+
+/**
+ * DateFormat is an abstract class for a family of classes that convert dates and
+ * times from their internal representations to textual form and back again in a
+ * language-independent manner. Converting from the internal representation (milliseconds
+ * since midnight, January 1, 1970) to text is known as "formatting," and converting
+ * from text to millis is known as "parsing." We currently define only one concrete
+ * subclass of DateFormat: SimpleDateFormat, which can handle pretty much all normal
+ * date formatting and parsing actions.
+ * <P>
+ * DateFormat helps you to format and parse dates for any locale. Your code can
+ * be completely independent of the locale conventions for months, days of the
+ * week, or even the calendar format: lunar vs. solar.
+ * <P>
+ * To format a date for the current Locale, use one of the static factory
+ * methods:
+ * <pre>
+ * \code
+ * DateFormat* dfmt = DateFormat::createDateInstance();
+ * UDate myDate = Calendar::getNow();
+ * UnicodeString myString;
+ * myString = dfmt->format( myDate, myString );
+ * \endcode
+ * </pre>
+ * If you are formatting multiple numbers, it is more efficient to get the
+ * format and use it multiple times so that the system doesn't have to fetch the
+ * information about the local language and country conventions multiple times.
+ * <pre>
+ * \code
+ * DateFormat* df = DateFormat::createDateInstance();
+ * UnicodeString myString;
+ * UDate myDateArr[] = { 0.0, 100000000.0, 2000000000.0 }; // test values
+ * for (int32_t i = 0; i < 3; ++i) {
+ * myString.remove();
+ * cout << df->format( myDateArr[i], myString ) << endl;
+ * }
+ * \endcode
+ * </pre>
+ * To get specific fields of a date, you can use UFieldPosition to
+ * get specific fields.
+ * <pre>
+ * \code
+ * DateFormat* dfmt = DateFormat::createDateInstance();
+ * FieldPosition pos(DateFormat::YEAR_FIELD);
+ * UnicodeString myString;
+ * myString = dfmt->format( myDate, myString );
+ * cout << myString << endl;
+ * cout << pos.getBeginIndex() << "," << pos. getEndIndex() << endl;
+ * \endcode
+ * </pre>
+ * To format a date for a different Locale, specify it in the call to
+ * createDateInstance().
+ * <pre>
+ * \code
+ * DateFormat* df =
+ * DateFormat::createDateInstance( DateFormat::SHORT, Locale::getFrance());
+ * \endcode
+ * </pre>
+ * You can use a DateFormat to parse also.
+ * <pre>
+ * \code
+ * UErrorCode status = U_ZERO_ERROR;
+ * UDate myDate = df->parse(myString, status);
+ * \endcode
+ * </pre>
+ * Use createDateInstance() to produce the normal date format for that country.
+ * There are other static factory methods available. Use createTimeInstance()
+ * to produce the normal time format for that country. Use createDateTimeInstance()
+ * to produce a DateFormat that formats both date and time. You can pass in
+ * different options to these factory methods to control the length of the
+ * result; from SHORT to MEDIUM to LONG to FULL. The exact result depends on the
+ * locale, but generally:
+ * <ul type=round>
+ * <li> SHORT is completely numeric, such as 12/13/52 or 3:30pm
+ * <li> MEDIUM is longer, such as Jan 12, 1952
+ * <li> LONG is longer, such as January 12, 1952 or 3:30:32pm
+ * <li> FULL is pretty completely specified, such as
+ * Tuesday, April 12, 1952 AD or 3:30:42pm PST.
+ * </ul>
+ * You can also set the time zone on the format if you wish. If you want even
+ * more control over the format or parsing, (or want to give your users more
+ * control), you can try casting the DateFormat you get from the factory methods
+ * to a SimpleDateFormat. This will work for the majority of countries; just
+ * remember to chck getDynamicClassID() before carrying out the cast.
+ * <P>
+ * You can also use forms of the parse and format methods with ParsePosition and
+ * FieldPosition to allow you to
+ * <ul type=round>
+ * <li> Progressively parse through pieces of a string.
+ * <li> Align any particular field, or find out where it is for selection
+ * on the screen.
+ * </ul>
+ *
+ * <p><em>User subclasses are not supported.</em> While clients may write
+ * subclasses, such code will not necessarily work and will not be
+ * guaranteed to work stably from release to release.

- * This class represents the set of symbols needed by DecimalFormat
- * to format numbers. DecimalFormat creates for itself an instance of
- * DecimalFormatSymbols from its locale data. If you need to change any
- * of these symbols, you can get the DecimalFormatSymbols object from
- * your DecimalFormat and modify it.
- * <P>
- * Here are the special characters used in the parts of the
- * subpattern, with notes on their usage.
- * <pre>
- * \code
- * Symbol Meaning
- * 0 a digit
- * # a digit, zero shows as absent
- * . placeholder for decimal separator
- * , placeholder for grouping separator.
- * ; separates formats.
- * - default negative prefix.
- * % divide by 100 and show as percentage
- * X any other characters can be used in the prefix or suffix
- * ' used to quote special characters in a prefix or suffix.
- * \endcode
- * </pre>
- * [Notes]
- * <P>
- * If there is no explicit negative subpattern, - is prefixed to the
- * positive form. That is, "0.00" alone is equivalent to "0.00;-0.00".
- * <P>
- * The grouping separator is commonly used for thousands, but in some
- * countries for ten-thousands. The interval is a constant number of
- * digits between the grouping characters, such as 100,000,000 or 1,0000,0000.
- * If you supply a pattern with multiple grouping characters, the interval
- * between the last one and the end of the integer is the one that is
- * used. So "#,##,###,####" == "######,####" == "##,####,####".
- * <P>
- * This class only handles localized digits where the 10 digits are
- * contiguous in Unicode, from 0 to 9. Other digits sets (such as
- * superscripts) would need a different subclass.

+ * [Notes]
+ * <P>
+ * If there is no explicit negative subpattern, - is prefixed to the
+ * positive form. That is, "0.00" alone is equivalent to "0.00;-0.00".
+ * <P>
+ * The grouping separator is commonly used for thousands, but in some
+ * countries for ten-thousands. The interval is a constant number of
+ * digits between the grouping characters, such as 100,000,000 or 1,0000,0000.
+ * If you supply a pattern with multiple grouping characters, the interval
+ * between the last one and the end of the integer is the one that is
+ * used. So "#,##,###,####" == "######,####" == "##,####,####".
+ * <P>
+ * This class only handles localized digits where the 10 digits are

-/**
- * DecimalFormat is a concrete subclass of NumberFormat that formats decimal
- * numbers. It has a variety of features designed to make it possible to parse
- * and format numbers in any locale, including support for Western, Arabic, or
- * Indic digits. It also supports different flavors of numbers, including
- * integers ("123"), fixed-point numbers ("123.4"), scientific notation
- * ("1.23E4"), percentages ("12%"), and currency amounts ("$123"). All of these
- * flavors can be easily localized.
- *
- * <p>To obtain a NumberFormat for a specific locale (including the default
- * locale) call one of NumberFormat's factory methods such as
- * createInstance(). Do not call the DecimalFormat constructors directly, unless
- * you know what you are doing, since the NumberFormat factory methods may
- * return subclasses other than DecimalFormat.
- *
- * <p><strong>Example Usage</strong>
- *
- * \code
- * // Normally we would have a GUI with a menu for this
- * int32_t locCount;
- * const Locale* locales = NumberFormat::getAvailableLocales(locCount);
- *
- * double myNumber = -1234.56;
- * UErrorCode success = U_ZERO_ERROR;
- * NumberFormat* form;
- *
- * // Print out a number with the localized number, currency and percent
- * // format for each locale.
- * UnicodeString countryName;
- * UnicodeString displayName;
- * UnicodeString str;
- * UnicodeString pattern;
- * Formattable fmtable;
- * for (int32_t j = 0; j < 3; ++j) {
- * cout << endl << "FORMAT " << j << endl;
- * for (int32_t i = 0; i < locCount; ++i) {
- * if (locales[i].getCountry(countryName).size() == 0) {
- * // skip language-only
- * continue;
- * }
- * switch (j) {
- * case 0:
- * form = NumberFormat::createInstance(locales[i], success ); break;
- * case 1:
- * form = NumberFormat::createCurrencyInstance(locales[i], success ); break;
- * default:
- * form = NumberFormat::createPercentInstance(locales[i], success ); break;
- * }
- * if (form) {
- * str.remove();
- * pattern = ((DecimalFormat*)form)->toPattern(pattern);
- * cout << locales[i].getDisplayName(displayName) << ": " << pattern;
- * cout << " -> " << form->format(myNumber,str) << endl;
- * form->parse(form->format(myNumber,str), fmtable, success);
- * delete form;
- * }
- * }
- * }
- * \endcode
- *
- * <p><strong>Patterns</strong>
- *
- * <p>A DecimalFormat consists of a <em>pattern</em> and a set of
- * <em>symbols</em>. The pattern may be set directly using
- * applyPattern(), or indirectly using other API methods which
- * manipulate aspects of the pattern, such as the minimum number of integer
- * digits. The symbols are stored in a DecimalFormatSymbols
- * object. When using the NumberFormat factory methods, the
- * pattern and symbols are read from ICU's locale data.
- *
- * <p><strong>Special Pattern Characters</strong>
- *
- * <p>Many characters in a pattern are taken literally; they are matched during
- * parsing and output unchanged during formatting. Special characters, on the
- * other hand, stand for other characters, strings, or classes of characters.
- * For example, the '#' character is replaced by a localized digit. Often the
- * replacement character is the same as the pattern character; in the U.S. locale,
- * the ',' grouping character is replaced by ','. However, the replacement is
- * still happening, and if the symbols are modified, the grouping character
- * changes. Some special characters affect the behavior of the formatter by
- * their presence; for example, if the percent character is seen, then the
- * value is multiplied by 100 before being displayed.
- *
- * <p>To insert a special character in a pattern as a literal, that is, without
- * any special meaning, the character must be quoted. There are some exceptions to
- * this which are noted below.
- *
- * <p>The characters listed here are used in non-localized patterns. Localized
- * patterns use the corresponding characters taken from this formatter's
- * DecimalFormatSymbols object instead, and these characters lose
- * their special status. Two exceptions are the currency sign and quote, which
- * are not localized.

- *
- * <p>A DecimalFormat pattern contains a postive and negative
- * subpattern, for example, "#,##0.00;(#,##0.00)". Each subpattern has a
- * prefix, a numeric part, and a suffix. If there is no explicit negative
- * subpattern, the negative subpattern is the localized minus sign prefixed to the
- * positive subpattern. That is, "0.00" alone is equivalent to "0.00;-0.00". If there
- * is an explicit negative subpattern, it serves only to specify the negative
- * prefix and suffix; the number of digits, minimal digits, and other
- * characteristics are ignored in the negative subpattern. That means that
- * "#,##0.0#;(#)" has precisely the same result as "#,##0.0#;(#,##0.0#)".
- *
- * <p>The prefixes, suffixes, and various symbols used for infinity, digits,
- * thousands separators, decimal separators, etc. may be set to arbitrary
- * values, and they will appear properly during formatting. However, care must
- * be taken that the symbols and strings do not conflict, or parsing will be
- * unreliable. For example, either the positive and negative prefixes or the
- * suffixes must be distinct for parse() to be able
- * to distinguish positive from negative values. Another example is that the
- * decimal separator and thousands separator should be distinct characters, or
- * parsing will be impossible.
- *
- * <p>The <em>grouping separator</em> is a character that separates clusters of
- * integer digits to make large numbers more legible. It commonly used for
- * thousands, but in some locales it separates ten-thousands. The <em>grouping
- * size</em> is the number of digits between the grouping separators, such as 3
- * for "100,000,000" or 4 for "1 0000 0000". There are actually two different
- * grouping sizes: One used for the least significant integer digits, the
- * <em>primary grouping size</em>, and one used for all others, the
- * <em>secondary grouping size</em>. In most locales these are the same, but
- * sometimes they are different. For example, if the primary grouping interval
- * is 3, and the secondary is 2, then this corresponds to the pattern
- * "#,##,##0", and the number 123456789 is formatted as "12,34,56,789". If a
- * pattern contains multiple grouping separators, the interval between the last
- * one and the end of the integer defines the primary grouping size, and the
- * interval between the last two defines the secondary grouping size. All others
- * are ignored, so "#,##,###,####" == "###,###,####" == "##,#,###,####".
- *
- * <p>Illegal patterns, such as "#.#.#" or "#.###,###", will cause
- * DecimalFormat to set a failing UErrorCode.
- *
- * <p><strong>Pattern BNF</strong>
- *
- * <pre>
- * pattern := subpattern (';' subpattern)?
- * subpattern := prefix? number exponent? suffix?
- * number := (integer ('.' fraction)?) | sigDigits
- * prefix := '\\u0000'..'\\uFFFD' - specialCharacters
- * suffix := '\\u0000'..'\\uFFFD' - specialCharacters
- * integer := '#'* '0'* '0'
- * fraction := '0'* '#'*
- * sigDigits := '#'* '@' '@'* '#'*
- * exponent := 'E' '+'? '0'* '0'
- * padSpec := '*' padChar
- * padChar := '\\u0000'..'\\uFFFD' - quote
- *
- * Notation:
- * X* 0 or more instances of X
- * X? 0 or 1 instances of X
- * X|Y either X or Y
- * C..D any character from C up to D, inclusive
- * S-T characters in S, except those in T
- * </pre>
- * The first subpattern is for positive numbers. The second (optional)
- * subpattern is for negative numbers.
- *
- * <p>Not indicated in the BNF syntax above:
- *
- * <ul><li>The grouping separator ',' can occur inside the integer and
- * sigDigits elements, between any two pattern characters of that
- * element, as long as the integer or sigDigits element is not
- * followed by the exponent element.
- *
- * <li>Two grouping intervals are recognized: That between the
- * decimal point and the first grouping symbol, and that
- * between the first and second grouping symbols. These
- * intervals are identical in most locales, but in some
- * locales they differ. For example, the pattern
- * "#,##,###" formats the number 123456789 as
- * "12,34,56,789".</li>
- *
- * <li>The pad specifier <code>padSpec</code> may appear before the prefix,
- * after the prefix, before the suffix, after the suffix, or not at all.
- *
- * <li>In place of '0', the digits '1' through '9' may be used to
- * indicate a rounding increment.
- * </ul>
- *
- * <p><strong>Parsing</strong>
- *
- * <p>DecimalFormat parses all Unicode characters that represent
- * decimal digits, as defined by u_charDigitValue(). In addition,
- * DecimalFormat also recognizes as digits the ten consecutive
- * characters starting with the localized zero digit defined in the
- * DecimalFormatSymbols object. During formatting, the
- * DecimalFormatSymbols-based digits are output.
- *
- * <p>During parsing, grouping separators are ignored.
- *
- * <p>If parse(UnicodeString&,Formattable&,ParsePosition&)
- * fails to parse a string, it leaves the parse position unchanged.
- * The convenience method parse(UnicodeString&,Formattable&,UErrorCode&)
- * indicates parse failure by setting a failing
- * UErrorCode.
- *
- * <p><strong>Formatting</strong>
- *
- * <p>Formatting is guided by several parameters, all of which can be
- * specified either using a pattern or using the API. The following
- * description applies to formats that do not use <a href="#sci">scientific
- * notation</a> or <a href="#sigdig">significant digits</a>.
- *
- * <ul><li>If the number of actual integer digits exceeds the
- * <em>maximum integer digits</em>, then only the least significant
- * digits are shown. For example, 1997 is formatted as "97" if the
- * maximum integer digits is set to 2.
- *
- * <li>If the number of actual integer digits is less than the
- * <em>minimum integer digits</em>, then leading zeros are added. For
- * example, 1997 is formatted as "01997" if the minimum integer digits
- * is set to 5.
- *
- * <li>If the number of actual fraction digits exceeds the <em>maximum
- * fraction digits</em>, then half-even rounding it performed to the
- * maximum fraction digits. For example, 0.125 is formatted as "0.12"
- * if the maximum fraction digits is 2. This behavior can be changed
- * by specifying a rounding increment and a rounding mode.
- *
- * <li>If the number of actual fraction digits is less than the
- * <em>minimum fraction digits</em>, then trailing zeros are added.
- * For example, 0.125 is formatted as "0.1250" if the mimimum fraction
- * digits is set to 4.
- *
- * <li>Trailing fractional zeros are not displayed if they occur
- * <em>j</em> positions after the decimal, where <em>j</em> is less
- * than the maximum fraction digits. For example, 0.10004 is
- * formatted as "0.1" if the maximum fraction digits is four or less.
- * </ul>
- *
- * <p><strong>Special Values</strong>
- *
- * <p><code>NaN</code> is represented as a single character, typically
- * <code>\\uFFFD</code>. This character is determined by the
- * DecimalFormatSymbols object. This is the only value for which
- * the prefixes and suffixes are not used.
- *
- * <p>Infinity is represented as a single character, typically
- * <code>\\u221E</code>, with the positive or negative prefixes and suffixes
- * applied. The infinity character is determined by the
- * DecimalFormatSymbols object.
- *
- * <a name="sci"><strong>Scientific Notation</strong></a>
- *
- * <p>Numbers in scientific notation are expressed as the product of a mantissa
- * and a power of ten, for example, 1234 can be expressed as 1.234 x 10<sup>3</sup>. The
- * mantissa is typically in the half-open interval [1.0, 10.0) or sometimes [0.0, 1.0),
- * but it need not be. DecimalFormat supports arbitrary mantissas.
- * DecimalFormat can be instructed to use scientific
- * notation through the API or through the pattern. In a pattern, the exponent
- * character immediately followed by one or more digit characters indicates
- * scientific notation. Example: "0.###E0" formats the number 1234 as
- * "1.234E3".
- *
- * <ul>
- * <li>The number of digit characters after the exponent character gives the
- * minimum exponent digit count. There is no maximum. Negative exponents are
- * formatted using the localized minus sign, <em>not</em> the prefix and suffix
- * from the pattern. This allows patterns such as "0.###E0 m/s". To prefix
- * positive exponents with a localized plus sign, specify '+' between the
- * exponent and the digits: "0.###E+0" will produce formats "1E+1", "1E+0",
- * "1E-1", etc. (In localized patterns, use the localized plus sign rather than
- * '+'.)
- *
- * <li>The minimum number of integer digits is achieved by adjusting the
- * exponent. Example: 0.00123 formatted with "00.###E0" yields "12.3E-4". This
- * only happens if there is no maximum number of integer digits. If there is a
- * maximum, then the minimum number of integer digits is fixed at one.
- *
- * <li>The maximum number of integer digits, if present, specifies the exponent
- * grouping. The most common use of this is to generate <em>engineering
- * notation</em>, in which the exponent is a multiple of three, e.g.,
- * "##0.###E0". The number 12345 is formatted using "##0.####E0" as "12.345E3".
- *
- * <li>When using scientific notation, the formatter controls the
- * digit counts using significant digits logic. The maximum number of
- * significant digits limits the total number of integer and fraction
- * digits that will be shown in the mantissa; it does not affect
- * parsing. For example, 12345 formatted with "##0.##E0" is "12.3E3".
- * See the section on significant digits for more details.
- *
- * <li>The number of significant digits shown is determined as
- * follows: If areSignificantDigitsUsed() returns false, then the
- * minimum number of significant digits shown is one, and the maximum
- * number of significant digits shown is the sum of the <em>minimum
- * integer</em> and <em>maximum fraction</em> digits, and is
- * unaffected by the maximum integer digits. If this sum is zero,
- * then all significant digits are shown. If
- * areSignificantDigitsUsed() returns true, then the significant digit
- * counts are specified by getMinimumSignificantDigits() and
- * getMaximumSignificantDigits(). In this case, the number of
- * integer digits is fixed at one, and there is no exponent grouping.
- *
- * <li>Exponential patterns may not contain grouping separators.
- * </ul>
- *
- * <a name="sigdig"><strong>Significant Digits</strong></a>
- *
- * <code>DecimalFormat</code> has two ways of controlling how many
- * digits are shows: (a) significant digits counts, or (b) integer and
- * fraction digit counts. Integer and fraction digit counts are
- * described above. When a formatter is using significant digits
- * counts, the number of integer and fraction digits is not specified
- * directly, and the formatter settings for these counts are ignored.
- * Instead, the formatter uses however many integer and fraction
- * digits are required to display the specified number of significant
- * digits. Examples:
- *
- * <table border=0 cellspacing=3 cellpadding=0>
- * <tr bgcolor="#ccccff">
- * <td align=left>Pattern
- * <td align=left>Minimum significant digits
- * <td align=left>Maximum significant digits
- * <td align=left>Number
- * <td align=left>Output of format()
- * <tr valign=top>
- * <td><code>\@\@\@</code>
- * <td>3
- * <td>3
- * <td>12345
- * <td><code>12300</code>
- * <tr valign=top bgcolor="#eeeeff">
- * <td><code>\@\@\@</code>
- * <td>3
- * <td>3
- * <td>0.12345
- * <td><code>0.123</code>
- * <tr valign=top>
- * <td><code>\@\@##</code>
- * <td>2
- * <td>4
- * <td>3.14159
- * <td><code>3.142</code>
- * <tr valign=top bgcolor="#eeeeff">
- * <td><code>\@\@##</code>
- * <td>2
- * <td>4
- * <td>1.23004
- * <td><code>1.23</code>
- * </table>
- *
- * <ul>
- * <li>Significant digit counts may be expressed using patterns that
- * specify a minimum and maximum number of significant digits. These
- * are indicated by the <code>'@'</code> and <code>'#'</code>
- * characters. The minimum number of significant digits is the number
- * of <code>'@'</code> characters. The maximum number of significant
- * digits is the number of <code>'@'</code> characters plus the number
- * of <code>'#'</code> characters following on the right. For
- * example, the pattern <code>"@@@"</code> indicates exactly 3
- * significant digits. The pattern <code>"@##"</code> indicates from
- * 1 to 3 significant digits. Trailing zero digits to the right of
- * the decimal separator are suppressed after the minimum number of
- * significant digits have been shown. For example, the pattern
- * <code>"@##"</code> formats the number 0.1203 as
- * <code>"0.12"</code>.
- *
- * <li>If a pattern uses significant digits, it may not contain a
- * decimal separator, nor the <code>'0'</code> pattern character.
- * Patterns such as <code>"@00"</code> or <code>"@.###"</code> are
- * disallowed.
- *
- * <li>Any number of <code>'#'</code> characters may be prepended to
- * the left of the leftmost <code>'@'</code> character. These have no
- * effect on the minimum and maximum significant digits counts, but
- * may be used to position grouping separators. For example,
- * <code>"#,#@#"</code> indicates a minimum of one significant digits,
- * a maximum of two significant digits, and a grouping size of three.
- *
- * <li>In order to enable significant digits formatting, use a pattern
- * containing the <code>'@'</code> pattern character. Alternatively,
- * call setSignificantDigitsUsed(TRUE).
- *
- * <li>In order to disable significant digits formatting, use a
- * pattern that does not contain the <code>'@'</code> pattern
- * character. Alternatively, call setSignificantDigitsUsed(FALSE).
- *
- * <li>The number of significant digits has no effect on parsing.
- *
- * <li>Significant digits may be used together with exponential notation. Such
- * patterns are equivalent to a normal exponential pattern with a minimum and
- * maximum integer digit count of one, a minimum fraction digit count of
- * <code>getMinimumSignificantDigits() - 1</code>, and a maximum fraction digit
- * count of <code>getMaximumSignificantDigits() - 1</code>. For example, the
- * pattern <code>"@@###E0"</code> is equivalent to <code>"0.0###E0"</code>.
- *
- * <li>If signficant digits are in use, then the integer and fraction
- * digit counts, as set via the API, are ignored. If significant
- * digits are not in use, then the signficant digit counts, as set via
- * the API, are ignored.
- *
- * </ul>
- *
- * <p><strong>Padding</strong>
- *
- * <p>DecimalFormat supports padding the result of
- * format() to a specific width. Padding may be specified either
- * through the API or through the pattern syntax. In a pattern the pad escape
- * character, followed by a single pad character, causes padding to be parsed
- * and formatted. The pad escape character is '*' in unlocalized patterns, and
- * can be localized using DecimalFormatSymbols::setSymbol() with a
- * DecimalFormatSymbols::kPadEscapeSymbol
- * selector. For example, <code>"$*x#,##0.00"</code> formats 123 to
- * <code>"$xx123.00"</code>, and 1234 to <code>"$1,234.00"</code>.
- *
- * <ul>
- * <li>When padding is in effect, the width of the positive subpattern,
- * including prefix and suffix, determines the format width. For example, in
- * the pattern <code>"* #0 o''clock"</code>, the format width is 10.
- *
- * <li>The width is counted in 16-bit code units (UChars).
- *
- * <li>Some parameters which usually do not matter have meaning when padding is
- * used, because the pattern width is significant with padding. In the pattern
- * "* ##,##,#,##0.##", the format width is 14. The initial characters "##,##,"
- * do not affect the grouping size or maximum integer digits, but they do affect
- * the format width.
- *
- * <li>Padding may be inserted at one of four locations: before the prefix,
- * after the prefix, before the suffix, or after the suffix. If padding is
- * specified in any other location, applyPattern()
- * sets a failing UErrorCode. If there is no prefix,
- * before the prefix and after the prefix are equivalent, likewise for the
- * suffix.
- *
- * <li>When specified in a pattern, the 32-bit code point immediately
- * following the pad escape is the pad character. This may be any character,
- * including a special pattern character. That is, the pad escape
- * <em>escapes</em> the following character. If there is no character after
- * the pad escape, then the pattern is illegal.
- *
- * </ul>
- *
- * <p><strong>Rounding</strong>
- *
- * <p>DecimalFormat supports rounding to a specific increment. For
- * example, 1230 rounded to the nearest 50 is 1250. 1.234 rounded to the
- * nearest 0.65 is 1.3. The rounding increment may be specified through the API
- * or in a pattern. To specify a rounding increment in a pattern, include the
- * increment in the pattern itself. "#,#50" specifies a rounding increment of
- * 50. "#,##0.05" specifies a rounding increment of 0.05.
- *
- * <ul>
- * <li>Rounding only affects the string produced by formatting. It does
- * not affect parsing or change any numerical values.
- *
- * <li>A <em>rounding mode</em> determines how values are rounded; see
- * DecimalFormat::ERoundingMode. Rounding increments specified in
- * patterns use the default mode, DecimalFormat::kRoundHalfEven.
- *
- * <li>Some locales use rounding in their currency formats to reflect the
- * smallest currency denomination.
- *
- * <li>In a pattern, digits '1' through '9' specify rounding, but otherwise
- * behave identically to digit '0'.
- * </ul>
- *
- * <p><strong>Synchronization</strong>
- *
- * <p>DecimalFormat objects are not synchronized. Multiple
- * threads should not access one formatter concurrently.
- *
- * <p><strong>Subclassing</strong>
- *
- * <p><em>User subclasses are not supported.</em> While clients may write
- * subclasses, such code will not necessarily work and will not be
- * guaranteed to work stably from release to release.

+/**
+ * DecimalFormat is a concrete subclass of NumberFormat that formats decimal
+ * numbers. It has a variety of features designed to make it possible to parse
+ * and format numbers in any locale, including support for Western, Arabic, or
+ * Indic digits. It also supports different flavors of numbers, including
+ * integers ("123"), fixed-point numbers ("123.4"), scientific notation
+ * ("1.23E4"), percentages ("12%"), and currency amounts ("$123"). All of these
+ * flavors can be easily localized.
+ *
+ * <p>To obtain a NumberFormat for a specific locale (including the default
+ * locale) call one of NumberFormat's factory methods such as
+ * createInstance(). Do not call the DecimalFormat constructors directly, unless
+ * you know what you are doing, since the NumberFormat factory methods may
+ * return subclasses other than DecimalFormat.
+ *
+ * <p><strong>Example Usage</strong>
+ *
+ * \code
+ * // Normally we would have a GUI with a menu for this
+ * int32_t locCount;
+ * const Locale* locales = NumberFormat::getAvailableLocales(locCount);
+ *
+ * double myNumber = -1234.56;
+ * UErrorCode success = U_ZERO_ERROR;
+ * NumberFormat* form;
+ *
+ * // Print out a number with the localized number, currency and percent
+ * // format for each locale.
+ * UnicodeString countryName;
+ * UnicodeString displayName;
+ * UnicodeString str;
+ * UnicodeString pattern;
+ * Formattable fmtable;
+ * for (int32_t j = 0; j < 3; ++j) {
+ * cout << endl << "FORMAT " << j << endl;
+ * for (int32_t i = 0; i < locCount; ++i) {
+ * if (locales[i].getCountry(countryName).size() == 0) {
+ * // skip language-only
+ * continue;
+ * }
+ * switch (j) {
+ * case 0:
+ * form = NumberFormat::createInstance(locales[i], success ); break;
+ * case 1:
+ * form = NumberFormat::createCurrencyInstance(locales[i], success ); break;
+ * default:
+ * form = NumberFormat::createPercentInstance(locales[i], success ); break;
+ * }
+ * if (form) {
+ * str.remove();
+ * pattern = ((DecimalFormat*)form)->toPattern(pattern);
+ * cout << locales[i].getDisplayName(displayName) << ": " << pattern;
+ * cout << " -> " << form->format(myNumber,str) << endl;
+ * form->parse(form->format(myNumber,str), fmtable, success);
+ * delete form;
+ * }
+ * }
+ * }
+ * \endcode
+ *
+ * <p><strong>Patterns</strong>
+ *
+ * <p>A DecimalFormat consists of a <em>pattern</em> and a set of
+ * <em>symbols</em>. The pattern may be set directly using
+ * applyPattern(), or indirectly using other API methods which
+ * manipulate aspects of the pattern, such as the minimum number of integer
+ * digits. The symbols are stored in a DecimalFormatSymbols
+ * object. When using the NumberFormat factory methods, the
+ * pattern and symbols are read from ICU's locale data.
+ *
+ * <p><strong>Special Pattern Characters</strong>
+ *
+ * <p>Many characters in a pattern are taken literally; they are matched during
+ * parsing and output unchanged during formatting. Special characters, on the
+ * other hand, stand for other characters, strings, or classes of characters.
+ * For example, the '#' character is replaced by a localized digit. Often the
+ * replacement character is the same as the pattern character; in the U.S. locale,
+ * the ',' grouping character is replaced by ','. However, the replacement is
+ * still happening, and if the symbols are modified, the grouping character
+ * changes. Some special characters affect the behavior of the formatter by
+ * their presence; for example, if the percent character is seen, then the
+ * value is multiplied by 100 before being displayed.
+ *
+ * <p>To insert a special character in a pattern as a literal, that is, without
+ * any special meaning, the character must be quoted. There are some exceptions to
+ * this which are noted below.
+ *
+ * <p>The characters listed here are used in non-localized patterns. Localized
+ * patterns use the corresponding characters taken from this formatter's
+ * DecimalFormatSymbols object instead, and these characters lose
+ * their special status. Two exceptions are the currency sign and quote, which
+ * are not localized.

+ *
+ * <p>A DecimalFormat pattern contains a postive and negative
+ * subpattern, for example, "#,##0.00;(#,##0.00)". Each subpattern has a
+ * prefix, a numeric part, and a suffix. If there is no explicit negative
+ * subpattern, the negative subpattern is the localized minus sign prefixed to the
+ * positive subpattern. That is, "0.00" alone is equivalent to "0.00;-0.00". If there
+ * is an explicit negative subpattern, it serves only to specify the negative
+ * prefix and suffix; the number of digits, minimal digits, and other
+ * characteristics are ignored in the negative subpattern. That means that
+ * "#,##0.0#;(#)" has precisely the same result as "#,##0.0#;(#,##0.0#)".
+ *
+ * <p>The prefixes, suffixes, and various symbols used for infinity, digits,
+ * thousands separators, decimal separators, etc. may be set to arbitrary
+ * values, and they will appear properly during formatting. However, care must
+ * be taken that the symbols and strings do not conflict, or parsing will be
+ * unreliable. For example, either the positive and negative prefixes or the
+ * suffixes must be distinct for parse() to be able
+ * to distinguish positive from negative values. Another example is that the
+ * decimal separator and thousands separator should be distinct characters, or
+ * parsing will be impossible.
+ *
+ * <p>The <em>grouping separator</em> is a character that separates clusters of
+ * integer digits to make large numbers more legible. It commonly used for
+ * thousands, but in some locales it separates ten-thousands. The <em>grouping
+ * size</em> is the number of digits between the grouping separators, such as 3
+ * for "100,000,000" or 4 for "1 0000 0000". There are actually two different
+ * grouping sizes: One used for the least significant integer digits, the
+ * <em>primary grouping size</em>, and one used for all others, the
+ * <em>secondary grouping size</em>. In most locales these are the same, but
+ * sometimes they are different. For example, if the primary grouping interval
+ * is 3, and the secondary is 2, then this corresponds to the pattern
+ * "#,##,##0", and the number 123456789 is formatted as "12,34,56,789". If a
+ * pattern contains multiple grouping separators, the interval between the last
+ * one and the end of the integer defines the primary grouping size, and the
+ * interval between the last two defines the secondary grouping size. All others
+ * are ignored, so "#,##,###,####" == "###,###,####" == "##,#,###,####".
+ *
+ * <p>Illegal patterns, such as "#.#.#" or "#.###,###", will cause
+ * DecimalFormat to set a failing UErrorCode.
+ *
+ * <p><strong>Pattern BNF</strong>
+ *
+ * <pre>
+ * pattern := subpattern (';' subpattern)?
+ * subpattern := prefix? number exponent? suffix?
+ * number := (integer ('.' fraction)?) | sigDigits
+ * prefix := '\\u0000'..'\\uFFFD' - specialCharacters
+ * suffix := '\\u0000'..'\\uFFFD' - specialCharacters
+ * integer := '#'* '0'* '0'
+ * fraction := '0'* '#'*
+ * sigDigits := '#'* '@' '@'* '#'*
+ * exponent := 'E' '+'? '0'* '0'
+ * padSpec := '*' padChar
+ * padChar := '\\u0000'..'\\uFFFD' - quote
+ *
+ * Notation:
+ * X* 0 or more instances of X
+ * X? 0 or 1 instances of X
+ * X|Y either X or Y
+ * C..D any character from C up to D, inclusive
+ * S-T characters in S, except those in T
+ * </pre>
+ * The first subpattern is for positive numbers. The second (optional)
+ * subpattern is for negative numbers.
+ *
+ * <p>Not indicated in the BNF syntax above:
+ *
+ * <ul><li>The grouping separator ',' can occur inside the integer and
+ * sigDigits elements, between any two pattern characters of that
+ * element, as long as the integer or sigDigits element is not
+ * followed by the exponent element.
+ *
+ * <li>Two grouping intervals are recognized: That between the
+ * decimal point and the first grouping symbol, and that
+ * between the first and second grouping symbols. These
+ * intervals are identical in most locales, but in some
+ * locales they differ. For example, the pattern
+ * "#,##,###" formats the number 123456789 as
+ * "12,34,56,789".</li>
+ *
+ * <li>The pad specifier <code>padSpec</code> may appear before the prefix,
+ * after the prefix, before the suffix, after the suffix, or not at all.
+ *
+ * <li>In place of '0', the digits '1' through '9' may be used to
+ * indicate a rounding increment.
+ * </ul>
+ *
+ * <p><strong>Parsing</strong>
+ *
+ * <p>DecimalFormat parses all Unicode characters that represent
+ * decimal digits, as defined by u_charDigitValue(). In addition,
+ * DecimalFormat also recognizes as digits the ten consecutive
+ * characters starting with the localized zero digit defined in the
+ * DecimalFormatSymbols object. During formatting, the
+ * DecimalFormatSymbols-based digits are output.
+ *
+ * <p>During parsing, grouping separators are ignored.
+ *
+ * <p>If parse(UnicodeString&,Formattable&,ParsePosition&)
+ * fails to parse a string, it leaves the parse position unchanged.
+ * The convenience method parse(UnicodeString&,Formattable&,UErrorCode&)
+ * indicates parse failure by setting a failing
+ * UErrorCode.
+ *
+ * <p><strong>Formatting</strong>
+ *
+ * <p>Formatting is guided by several parameters, all of which can be
+ * specified either using a pattern or using the API. The following
+ * description applies to formats that do not use <a href="#sci">scientific
+ * notation</a> or <a href="#sigdig">significant digits</a>.
+ *
+ * <ul><li>If the number of actual integer digits exceeds the
+ * <em>maximum integer digits</em>, then only the least significant
+ * digits are shown. For example, 1997 is formatted as "97" if the
+ * maximum integer digits is set to 2.
+ *
+ * <li>If the number of actual integer digits is less than the
+ * <em>minimum integer digits</em>, then leading zeros are added. For
+ * example, 1997 is formatted as "01997" if the minimum integer digits
+ * is set to 5.
+ *
+ * <li>If the number of actual fraction digits exceeds the <em>maximum
+ * fraction digits</em>, then half-even rounding it performed to the
+ * maximum fraction digits. For example, 0.125 is formatted as "0.12"
+ * if the maximum fraction digits is 2. This behavior can be changed
+ * by specifying a rounding increment and a rounding mode.
+ *
+ * <li>If the number of actual fraction digits is less than the
+ * <em>minimum fraction digits</em>, then trailing zeros are added.
+ * For example, 0.125 is formatted as "0.1250" if the mimimum fraction
+ * digits is set to 4.
+ *
+ * <li>Trailing fractional zeros are not displayed if they occur
+ * <em>j</em> positions after the decimal, where <em>j</em> is less
+ * than the maximum fraction digits. For example, 0.10004 is
+ * formatted as "0.1" if the maximum fraction digits is four or less.
+ * </ul>
+ *
+ * <p><strong>Special Values</strong>
+ *
+ * <p><code>NaN</code> is represented as a single character, typically
+ * <code>\\uFFFD</code>. This character is determined by the
+ * DecimalFormatSymbols object. This is the only value for which
+ * the prefixes and suffixes are not used.
+ *
+ * <p>Infinity is represented as a single character, typically
+ * <code>\\u221E</code>, with the positive or negative prefixes and suffixes
+ * applied. The infinity character is determined by the
+ * DecimalFormatSymbols object.
+ *
+ * <a name="sci"><strong>Scientific Notation</strong></a>
+ *
+ * <p>Numbers in scientific notation are expressed as the product of a mantissa
+ * and a power of ten, for example, 1234 can be expressed as 1.234 x 10<sup>3</sup>. The
+ * mantissa is typically in the half-open interval [1.0, 10.0) or sometimes [0.0, 1.0),
+ * but it need not be. DecimalFormat supports arbitrary mantissas.
+ * DecimalFormat can be instructed to use scientific
+ * notation through the API or through the pattern. In a pattern, the exponent
+ * character immediately followed by one or more digit characters indicates
+ * scientific notation. Example: "0.###E0" formats the number 1234 as
+ * "1.234E3".
+ *
+ * <ul>
+ * <li>The number of digit characters after the exponent character gives the
+ * minimum exponent digit count. There is no maximum. Negative exponents are
+ * formatted using the localized minus sign, <em>not</em> the prefix and suffix
+ * from the pattern. This allows patterns such as "0.###E0 m/s". To prefix
+ * positive exponents with a localized plus sign, specify '+' between the
+ * exponent and the digits: "0.###E+0" will produce formats "1E+1", "1E+0",
+ * "1E-1", etc. (In localized patterns, use the localized plus sign rather than
+ * '+'.)
+ *
+ * <li>The minimum number of integer digits is achieved by adjusting the
+ * exponent. Example: 0.00123 formatted with "00.###E0" yields "12.3E-4". This
+ * only happens if there is no maximum number of integer digits. If there is a
+ * maximum, then the minimum number of integer digits is fixed at one.
+ *
+ * <li>The maximum number of integer digits, if present, specifies the exponent
+ * grouping. The most common use of this is to generate <em>engineering
+ * notation</em>, in which the exponent is a multiple of three, e.g.,
+ * "##0.###E0". The number 12345 is formatted using "##0.####E0" as "12.345E3".
+ *
+ * <li>When using scientific notation, the formatter controls the
+ * digit counts using significant digits logic. The maximum number of
+ * significant digits limits the total number of integer and fraction
+ * digits that will be shown in the mantissa; it does not affect
+ * parsing. For example, 12345 formatted with "##0.##E0" is "12.3E3".
+ * See the section on significant digits for more details.
+ *
+ * <li>The number of significant digits shown is determined as
+ * follows: If areSignificantDigitsUsed() returns false, then the
+ * minimum number of significant digits shown is one, and the maximum
+ * number of significant digits shown is the sum of the <em>minimum
+ * integer</em> and <em>maximum fraction</em> digits, and is
+ * unaffected by the maximum integer digits. If this sum is zero,
+ * then all significant digits are shown. If
+ * areSignificantDigitsUsed() returns true, then the significant digit
+ * counts are specified by getMinimumSignificantDigits() and
+ * getMaximumSignificantDigits(). In this case, the number of
+ * integer digits is fixed at one, and there is no exponent grouping.
+ *
+ * <li>Exponential patterns may not contain grouping separators.
+ * </ul>
+ *
+ * <a name="sigdig"><strong>Significant Digits</strong></a>
+ *
+ * <code>DecimalFormat</code> has two ways of controlling how many
+ * digits are shows: (a) significant digits counts, or (b) integer and
+ * fraction digit counts. Integer and fraction digit counts are
+ * described above. When a formatter is using significant digits
+ * counts, the number of integer and fraction digits is not specified
+ * directly, and the formatter settings for these counts are ignored.
+ * Instead, the formatter uses however many integer and fraction
+ * digits are required to display the specified number of significant
+ * digits. Examples:
+ *
+ * <table border=0 cellspacing=3 cellpadding=0>
+ * <tr bgcolor="#ccccff">
+ * <td align=left>Pattern
+ * <td align=left>Minimum significant digits
+ * <td align=left>Maximum significant digits
+ * <td align=left>Number
+ * <td align=left>Output of format()
+ * <tr valign=top>
+ * <td><code>\@\@\@</code>
+ * <td>3
+ * <td>3
+ * <td>12345
+ * <td><code>12300</code>
+ * <tr valign=top bgcolor="#eeeeff">
+ * <td><code>\@\@\@</code>
+ * <td>3
+ * <td>3
+ * <td>0.12345
+ * <td><code>0.123</code>
+ * <tr valign=top>
+ * <td><code>\@\@##</code>
+ * <td>2
+ * <td>4
+ * <td>3.14159
+ * <td><code>3.142</code>
+ * <tr valign=top bgcolor="#eeeeff">
+ * <td><code>\@\@##</code>
+ * <td>2
+ * <td>4
+ * <td>1.23004
+ * <td><code>1.23</code>
+ * </table>
+ *
+ * <ul>
+ * <li>Significant digit counts may be expressed using patterns that
+ * specify a minimum and maximum number of significant digits. These
+ * are indicated by the <code>'@'</code> and <code>'#'</code>
+ * characters. The minimum number of significant digits is the number
+ * of <code>'@'</code> characters. The maximum number of significant
+ * digits is the number of <code>'@'</code> characters plus the number
+ * of <code>'#'</code> characters following on the right. For
+ * example, the pattern <code>"@@@"</code> indicates exactly 3
+ * significant digits. The pattern <code>"@##"</code> indicates from
+ * 1 to 3 significant digits. Trailing zero digits to the right of
+ * the decimal separator are suppressed after the minimum number of
+ * significant digits have been shown. For example, the pattern
+ * <code>"@##"</code> formats the number 0.1203 as
+ * <code>"0.12"</code>.
+ *
+ * <li>If a pattern uses significant digits, it may not contain a
+ * decimal separator, nor the <code>'0'</code> pattern character.
+ * Patterns such as <code>"@00"</code> or <code>"@.###"</code> are
+ * disallowed.
+ *
+ * <li>Any number of <code>'#'</code> characters may be prepended to
+ * the left of the leftmost <code>'@'</code> character. These have no
+ * effect on the minimum and maximum significant digits counts, but
+ * may be used to position grouping separators. For example,
+ * <code>"#,#@#"</code> indicates a minimum of one significant digits,
+ * a maximum of two significant digits, and a grouping size of three.
+ *
+ * <li>In order to enable significant digits formatting, use a pattern
+ * containing the <code>'@'</code> pattern character. Alternatively,
+ * call setSignificantDigitsUsed(TRUE).
+ *
+ * <li>In order to disable significant digits formatting, use a
+ * pattern that does not contain the <code>'@'</code> pattern
+ * character. Alternatively, call setSignificantDigitsUsed(FALSE).
+ *
+ * <li>The number of significant digits has no effect on parsing.
+ *
+ * <li>Significant digits may be used together with exponential notation. Such
+ * patterns are equivalent to a normal exponential pattern with a minimum and
+ * maximum integer digit count of one, a minimum fraction digit count of
+ * <code>getMinimumSignificantDigits() - 1</code>, and a maximum fraction digit
+ * count of <code>getMaximumSignificantDigits() - 1</code>. For example, the
+ * pattern <code>"@@###E0"</code> is equivalent to <code>"0.0###E0"</code>.
+ *
+ * <li>If signficant digits are in use, then the integer and fraction
+ * digit counts, as set via the API, are ignored. If significant
+ * digits are not in use, then the signficant digit counts, as set via
+ * the API, are ignored.
+ *
+ * </ul>
+ *
+ * <p><strong>Padding</strong>
+ *
+ * <p>DecimalFormat supports padding the result of
+ * format() to a specific width. Padding may be specified either
+ * through the API or through the pattern syntax. In a pattern the pad escape
+ * character, followed by a single pad character, causes padding to be parsed
+ * and formatted. The pad escape character is '*' in unlocalized patterns, and
+ * can be localized using DecimalFormatSymbols::setSymbol() with a
+ * DecimalFormatSymbols::kPadEscapeSymbol
+ * selector. For example, <code>"$*x#,##0.00"</code> formats 123 to
+ * <code>"$xx123.00"</code>, and 1234 to <code>"$1,234.00"</code>.
+ *
+ * <ul>
+ * <li>When padding is in effect, the width of the positive subpattern,
+ * including prefix and suffix, determines the format width. For example, in
+ * the pattern <code>"* #0 o''clock"</code>, the format width is 10.
+ *
+ * <li>The width is counted in 16-bit code units (UChars).
+ *
+ * <li>Some parameters which usually do not matter have meaning when padding is
+ * used, because the pattern width is significant with padding. In the pattern
+ * "* ##,##,#,##0.##", the format width is 14. The initial characters "##,##,"
+ * do not affect the grouping size or maximum integer digits, but they do affect
+ * the format width.
+ *
+ * <li>Padding may be inserted at one of four locations: before the prefix,
+ * after the prefix, before the suffix, or after the suffix. If padding is
+ * specified in any other location, applyPattern()
+ * sets a failing UErrorCode. If there is no prefix,
+ * before the prefix and after the prefix are equivalent, likewise for the
+ * suffix.
+ *
+ * <li>When specified in a pattern, the 32-bit code point immediately
+ * following the pad escape is the pad character. This may be any character,
+ * including a special pattern character. That is, the pad escape
+ * <em>escapes</em> the following character. If there is no character after
+ * the pad escape, then the pattern is illegal.
+ *
+ * </ul>
+ *
+ * <p><strong>Rounding</strong>
+ *
+ * <p>DecimalFormat supports rounding to a specific increment. For
+ * example, 1230 rounded to the nearest 50 is 1250. 1.234 rounded to the
+ * nearest 0.65 is 1.3. The rounding increment may be specified through the API
+ * or in a pattern. To specify a rounding increment in a pattern, include the
+ * increment in the pattern itself. "#,#50" specifies a rounding increment of
+ * 50. "#,##0.05" specifies a rounding increment of 0.05.
+ *
+ * <ul>
+ * <li>Rounding only affects the string produced by formatting. It does
+ * not affect parsing or change any numerical values.
+ *
+ * <li>A <em>rounding mode</em> determines how values are rounded; see
+ * DecimalFormat::ERoundingMode. Rounding increments specified in
+ * patterns use the default mode, DecimalFormat::kRoundHalfEven.
+ *
+ * <li>Some locales use rounding in their currency formats to reflect the
+ * smallest currency denomination.
+ *
+ * <li>In a pattern, digits '1' through '9' specify rounding, but otherwise
+ * behave identically to digit '0'.
+ * </ul>
+ *
+ * <p><strong>Synchronization</strong>
+ *
+ * <p>DecimalFormat objects are not synchronized. Multiple
+ * threads should not access one formatter concurrently.
+ *
+ * <p><strong>Subclassing</strong>
+ *
+ * <p><em>User subclasses are not supported.</em> While clients may write
+ * subclasses, such code will not necessarily work and will not be
+ * guaranteed to work stably from release to release.

- * DateFormatSymbols is a public class for encapsulating localizable date-time
- * formatting data -- including timezone data. DateFormatSymbols is used by
- * DateFormat and SimpleDateFormat.
- * <P>
- * Rather than first creating a DateFormatSymbols to get a date-time formatter
- * by using a SimpleDateFormat constructor, clients are encouraged to create a
- * date-time formatter using the getTimeInstance(), getDateInstance(), or
- * getDateTimeInstance() method in DateFormat. Each of these methods can return a
- * date/time formatter initialized with a default format pattern along with the
- * date-time formatting data for a given or default locale. After a formatter is
- * created, clients may modify the format pattern using the setPattern function
- * as so desired. For more information on using these formatter factory
- * functions, see DateFormat.
- * <P>
- * If clients decide to create a date-time formatter with a particular format
- * pattern and locale, they can do so with new SimpleDateFormat(aPattern,
- * new DateFormatSymbols(aLocale)). This will load the appropriate date-time
- * formatting data from the locale.
- * <P>
- * DateFormatSymbols objects are clonable. When clients obtain a
- * DateFormatSymbols object, they can feel free to modify the date-time
- * formatting data as necessary. For instance, clients can
- * replace the localized date-time format pattern characters with the ones that
- * they feel easy to remember. Or they can change the representative cities
- * originally picked by default to using their favorite ones.
- * <P>
- * DateFormatSymbols are not expected to be subclassed. Data for a calendar is
- * loaded out of resource bundles. The 'type' parameter indicates the type of
- * calendar, for example, "gregorian" or "japanese". If the type is not gregorian
- * (or NULL, or an empty string) then the type is appended to the resource name,
- * for example, 'Eras_japanese' instead of 'Eras'. If the resource 'Eras_japanese' did
- * not exist (even in root), then this class will fall back to just 'Eras', that is,
- * Gregorian data. Therefore, the calendar implementor MUST ensure that the root
- * locale at least contains any resources that are to be particularized for the
- * calendar type.

+/**
+ * DateFormatSymbols is a public class for encapsulating localizable date-time
+ * formatting data -- including timezone data. DateFormatSymbols is used by
+ * DateFormat and SimpleDateFormat.
+ * <P>
+ * Rather than first creating a DateFormatSymbols to get a date-time formatter
+ * by using a SimpleDateFormat constructor, clients are encouraged to create a
+ * date-time formatter using the getTimeInstance(), getDateInstance(), or
+ * getDateTimeInstance() method in DateFormat. Each of these methods can return a
+ * date/time formatter initialized with a default format pattern along with the
+ * date-time formatting data for a given or default locale. After a formatter is
+ * created, clients may modify the format pattern using the setPattern function
+ * as so desired. For more information on using these formatter factory
+ * functions, see DateFormat.
+ * <P>
+ * If clients decide to create a date-time formatter with a particular format
+ * pattern and locale, they can do so with new SimpleDateFormat(aPattern,
+ * new DateFormatSymbols(aLocale)). This will load the appropriate date-time
+ * formatting data from the locale.
+ * <P>
+ * DateFormatSymbols objects are clonable. When clients obtain a
+ * DateFormatSymbols object, they can feel free to modify the date-time
+ * formatting data as necessary. For instance, clients can
+ * replace the localized date-time format pattern characters with the ones that
+ * they feel easy to remember. Or they can change the representative cities
+ * originally picked by default to using their favorite ones.
+ * <P>
+ * DateFormatSymbols are not expected to be subclassed. Data for a calendar is
+ * loaded out of resource bundles. The 'type' parameter indicates the type of
+ * calendar, for example, "gregorian" or "japanese". If the type is not gregorian
+ * (or NULL, or an empty string) then the type is appended to the resource name,
+ * for example, 'Eras_japanese' instead of 'Eras'. If the resource 'Eras_japanese' did
+ * not exist (even in root), then this class will fall back to just 'Eras', that is,
+ * Gregorian data. Therefore, the calendar implementor MUST ensure that the root
+ * locale at least contains any resources that are to be particularized for the
+ * calendar type.

-/**
- * DateIntervalFormat is a class for formatting and parsing date
- * intervals in a language-independent manner.
- * Date interval formatting is supported in Gregorian calendar only.
- * And only formatting is supported. Parsing is not supported.
- *
- * <P>
- * Date interval means from one date to another date,
- * for example, from "Jan 11, 2008" to "Jan 18, 2008".
- * We introduced class DateInterval to represent it.
- * DateInterval is a pair of UDate, which is
- * the standard milliseconds since 24:00 GMT, Jan 1, 1970.
- *
- * <P>
- * DateIntervalFormat formats a DateInterval into
- * text as compactly as possible.
- * For example, the date interval format from "Jan 11, 2008" to "Jan 18,. 2008"
- * is "Jan 11-18, 2008" for English.
- * And it parses text into DateInterval,
- * although initially, parsing is not supported.
- *
- * <P>
- * There is no structural information in date time patterns.
- * For any punctuations and string literals inside a date time pattern,
- * we do not know whether it is just a separator, or a prefix, or a suffix.
- * Without such information, so, it is difficult to generate a sub-pattern
- * (or super-pattern) by algorithm.
- * So, formatting a DateInterval is pattern-driven. It is very
- * similar to formatting in SimpleDateFormat.
- * We introduce class DateIntervalInfo to save date interval
- * patterns, similar to date time pattern in SimpleDateFormat.
- *
- * <P>
- * Logically, the interval patterns are mappings
- * from (skeleton, the_largest_different_calendar_field)
- * to (date_interval_pattern).
- *
- * <P>
- * A skeleton
- * <ol>
- * <li>
- * only keeps the field pattern letter and ignores all other parts
- * in a pattern, such as space, punctuations, and string literals.
- * </li>
- * <li>
- * hides the order of fields.
- * </li>
- * <li>
- * might hide a field's pattern letter length.
- * </li>
- * </ol>
- *
- * For those non-digit calendar fields, the pattern letter length is
- * important, such as MMM, MMMM, and MMMMM; EEE and EEEE,
- * and the field's pattern letter length is honored.
- *
- * For the digit calendar fields, such as M or MM, d or dd, yy or yyyy,
- * the field pattern length is ignored and the best match, which is defined
- * in date time patterns, will be returned without honor the field pattern
- * letter length in skeleton.
- *
- * <P>
- * The calendar fields we support for interval formatting are:
- * year, month, date, day-of-week, am-pm, hour, hour-of-day, and minute.
- * Those calendar fields can be defined in the following order:
- * year > month > date > hour (in day) > minute
- *
- * The largest different calendar fields between 2 calendars is the
- * first different calendar field in above order.
- *
- * For example: the largest different calendar fields between "Jan 10, 2007"
- * and "Feb 20, 2008" is year.
- *
- * <P>
- * For other calendar fields, the compact interval formatting is not
- * supported. And the interval format will be fall back to fall-back
- * patterns, which is mostly "{date0} - {date1}".
- *
- * <P>
- * There is a set of pre-defined static skeleton strings.
- * There are pre-defined interval patterns for those pre-defined skeletons
- * in locales' resource files.
- * For example, for a skeleton UDAT_YEAR_ABBR_MONTH_DAY, which is "yMMMd",
- * in en_US, if the largest different calendar field between date1 and date2
- * is "year", the date interval pattern is "MMM d, yyyy - MMM d, yyyy",
- * such as "Jan 10, 2007 - Jan 10, 2008".
- * If the largest different calendar field between date1 and date2 is "month",
- * the date interval pattern is "MMM d - MMM d, yyyy",
- * such as "Jan 10 - Feb 10, 2007".
- * If the largest different calendar field between date1 and date2 is "day",
- * the date interval pattern is ""MMM d-d, yyyy", such as "Jan 10-20, 2007".
- *
- * For date skeleton, the interval patterns when year, or month, or date is
- * different are defined in resource files.
- * For time skeleton, the interval patterns when am/pm, or hour, or minute is
- * different are defined in resource files.
- *
- * <P>
- * If a skeleton is not found in a locale's DateIntervalInfo, which means
- * the interval patterns for the skeleton is not defined in resource file,
- * the interval pattern will falls back to the interval "fallback" pattern
- * defined in resource file.
- * If the interval "fallback" pattern is not defined, the default fall-back
- * is "{date0} - {data1}".
- *
- * <P>
- * For the combination of date and time,
- * The rule to generate interval patterns are:
- * <ol>
- * <li>
- * when the year, month, or day differs, falls back to fall-back
- * interval pattern, which mostly is the concatenate the two original
- * expressions with a separator between,
- * For example, interval pattern from "Jan 10, 2007 10:10 am"
- * to "Jan 11, 2007 10:10am" is
- * "Jan 10, 2007 10:10 am - Jan 11, 2007 10:10am"
- * </li>
- * <li>
- * otherwise, present the date followed by the range expression
- * for the time.
- * For example, interval pattern from "Jan 10, 2007 10:10 am"
- * to "Jan 10, 2007 11:10am" is "Jan 10, 2007 10:10 am - 11:10am"
- * </li>
- * </ol>
- *
- *
- * <P>
- * If two dates are the same, the interval pattern is the single date pattern.
- * For example, interval pattern from "Jan 10, 2007" to "Jan 10, 2007" is
- * "Jan 10, 2007".
- *
- * Or if the presenting fields between 2 dates have the exact same values,
- * the interval pattern is the single date pattern.
- * For example, if user only requests year and month,
- * the interval pattern from "Jan 10, 2007" to "Jan 20, 2007" is "Jan 2007".
- *
- * <P>
- * DateIntervalFormat needs the following information for correct
- * formatting: time zone, calendar type, pattern, date format symbols,
- * and date interval patterns.
- * It can be instantiated in 2 ways:
- * <ol>
- * <li>
- * create an instance using default or given locale plus given skeleton.
- * Users are encouraged to created date interval formatter this way and
- * to use the pre-defined skeleton macros, such as
- * UDAT_YEAR_NUM_MONTH, which consists the calendar fields and
- * the format style.
- * </li>
- * <li>
- * create an instance using default or given locale plus given skeleton
- * plus a given DateIntervalInfo.
- * This factory method is for powerful users who want to provide their own
- * interval patterns.
- * Locale provides the timezone, calendar, and format symbols information.
- * Local plus skeleton provides full pattern information.
- * DateIntervalInfo provides the date interval patterns.
- * </li>
- * </ol>
- *
- * <P>
- * For the calendar field pattern letter, such as G, y, M, d, a, h, H, m, s etc.
- * DateIntervalFormat uses the same syntax as that of
- * DateTime format.
- *
- * <P>
- * Code Sample: general usage
- * <pre>
- * \code
- * // the date interval object which the DateIntervalFormat formats on
- * // and parses into
- * DateInterval* dtInterval = new DateInterval(1000*3600*24, 1000*3600*24*2);
- * UErrorCode status = U_ZERO_ERROR;
- * DateIntervalFormat* dtIntervalFmt = DateIntervalFormat::createInstance(
- * UDAT_YEAR_MONTH_DAY,
- * Locale("en", "GB", ""), status);
- * UnicodeUnicodeString dateIntervalString;
- * FieldPosition pos = 0;
- * // formatting
- * dtIntervalFmt->format(dtInterval, dateIntervalUnicodeString, pos, status);
- * delete dtIntervalFmt;
- * \endcode
- * </pre>

+/**
+ * DateIntervalFormat is a class for formatting and parsing date
+ * intervals in a language-independent manner.
+ * Date interval formatting is supported in Gregorian calendar only.
+ * And only formatting is supported. Parsing is not supported.
+ *
+ * <P>
+ * Date interval means from one date to another date,
+ * for example, from "Jan 11, 2008" to "Jan 18, 2008".
+ * We introduced class DateInterval to represent it.
+ * DateInterval is a pair of UDate, which is
+ * the standard milliseconds since 24:00 GMT, Jan 1, 1970.
+ *
+ * <P>
+ * DateIntervalFormat formats a DateInterval into
+ * text as compactly as possible.
+ * For example, the date interval format from "Jan 11, 2008" to "Jan 18,. 2008"
+ * is "Jan 11-18, 2008" for English.
+ * And it parses text into DateInterval,
+ * although initially, parsing is not supported.
+ *
+ * <P>
+ * There is no structural information in date time patterns.
+ * For any punctuations and string literals inside a date time pattern,
+ * we do not know whether it is just a separator, or a prefix, or a suffix.
+ * Without such information, so, it is difficult to generate a sub-pattern
+ * (or super-pattern) by algorithm.
+ * So, formatting a DateInterval is pattern-driven. It is very
+ * similar to formatting in SimpleDateFormat.
+ * We introduce class DateIntervalInfo to save date interval
+ * patterns, similar to date time pattern in SimpleDateFormat.
+ *
+ * <P>
+ * Logically, the interval patterns are mappings
+ * from (skeleton, the_largest_different_calendar_field)
+ * to (date_interval_pattern).
+ *
+ * <P>
+ * A skeleton
+ * <ol>
+ * <li>
+ * only keeps the field pattern letter and ignores all other parts
+ * in a pattern, such as space, punctuations, and string literals.
+ * </li>
+ * <li>
+ * hides the order of fields.
+ * </li>
+ * <li>
+ * might hide a field's pattern letter length.
+ * </li>
+ * </ol>
+ *
+ * For those non-digit calendar fields, the pattern letter length is
+ * important, such as MMM, MMMM, and MMMMM; EEE and EEEE,
+ * and the field's pattern letter length is honored.
+ *
+ * For the digit calendar fields, such as M or MM, d or dd, yy or yyyy,
+ * the field pattern length is ignored and the best match, which is defined
+ * in date time patterns, will be returned without honor the field pattern
+ * letter length in skeleton.
+ *
+ * <P>
+ * The calendar fields we support for interval formatting are:
+ * year, month, date, day-of-week, am-pm, hour, hour-of-day, and minute.
+ * Those calendar fields can be defined in the following order:
+ * year > month > date > hour (in day) > minute
+ *
+ * The largest different calendar fields between 2 calendars is the
+ * first different calendar field in above order.
+ *
+ * For example: the largest different calendar fields between "Jan 10, 2007"
+ * and "Feb 20, 2008" is year.
+ *
+ * <P>
+ * For other calendar fields, the compact interval formatting is not
+ * supported. And the interval format will be fall back to fall-back
+ * patterns, which is mostly "{date0} - {date1}".
+ *
+ * <P>
+ * There is a set of pre-defined static skeleton strings.
+ * There are pre-defined interval patterns for those pre-defined skeletons
+ * in locales' resource files.
+ * For example, for a skeleton UDAT_YEAR_ABBR_MONTH_DAY, which is "yMMMd",
+ * in en_US, if the largest different calendar field between date1 and date2
+ * is "year", the date interval pattern is "MMM d, yyyy - MMM d, yyyy",
+ * such as "Jan 10, 2007 - Jan 10, 2008".
+ * If the largest different calendar field between date1 and date2 is "month",
+ * the date interval pattern is "MMM d - MMM d, yyyy",
+ * such as "Jan 10 - Feb 10, 2007".
+ * If the largest different calendar field between date1 and date2 is "day",
+ * the date interval pattern is ""MMM d-d, yyyy", such as "Jan 10-20, 2007".
+ *
+ * For date skeleton, the interval patterns when year, or month, or date is
+ * different are defined in resource files.
+ * For time skeleton, the interval patterns when am/pm, or hour, or minute is
+ * different are defined in resource files.
+ *
+ * <P>
+ * If a skeleton is not found in a locale's DateIntervalInfo, which means
+ * the interval patterns for the skeleton is not defined in resource file,
+ * the interval pattern will falls back to the interval "fallback" pattern
+ * defined in resource file.
+ * If the interval "fallback" pattern is not defined, the default fall-back
+ * is "{date0} - {data1}".
+ *
+ * <P>
+ * For the combination of date and time,
+ * The rule to generate interval patterns are:
+ * <ol>
+ * <li>
+ * when the year, month, or day differs, falls back to fall-back
+ * interval pattern, which mostly is the concatenate the two original
+ * expressions with a separator between,
+ * For example, interval pattern from "Jan 10, 2007 10:10 am"
+ * to "Jan 11, 2007 10:10am" is
+ * "Jan 10, 2007 10:10 am - Jan 11, 2007 10:10am"
+ * </li>
+ * <li>
+ * otherwise, present the date followed by the range expression
+ * for the time.
+ * For example, interval pattern from "Jan 10, 2007 10:10 am"
+ * to "Jan 10, 2007 11:10am" is "Jan 10, 2007 10:10 am - 11:10am"
+ * </li>
+ * </ol>
+ *
+ *
+ * <P>
+ * If two dates are the same, the interval pattern is the single date pattern.
+ * For example, interval pattern from "Jan 10, 2007" to "Jan 10, 2007" is
+ * "Jan 10, 2007".
+ *
+ * Or if the presenting fields between 2 dates have the exact same values,
+ * the interval pattern is the single date pattern.
+ * For example, if user only requests year and month,
+ * the interval pattern from "Jan 10, 2007" to "Jan 20, 2007" is "Jan 2007".
+ *
+ * <P>
+ * DateIntervalFormat needs the following information for correct
+ * formatting: time zone, calendar type, pattern, date format symbols,
+ * and date interval patterns.
+ * It can be instantiated in 2 ways:
+ * <ol>
+ * <li>
+ * create an instance using default or given locale plus given skeleton.
+ * Users are encouraged to created date interval formatter this way and
+ * to use the pre-defined skeleton macros, such as
+ * UDAT_YEAR_NUM_MONTH, which consists the calendar fields and
+ * the format style.
+ * </li>
+ * <li>
+ * create an instance using default or given locale plus given skeleton
+ * plus a given DateIntervalInfo.
+ * This factory method is for powerful users who want to provide their own
+ * interval patterns.
+ * Locale provides the timezone, calendar, and format symbols information.
+ * Local plus skeleton provides full pattern information.
+ * DateIntervalInfo provides the date interval patterns.
+ * </li>
+ * </ol>
+ *
+ * <P>
+ * For the calendar field pattern letter, such as G, y, M, d, a, h, H, m, s etc.
+ * DateIntervalFormat uses the same syntax as that of
+ * DateTime format.
+ *
+ * <P>
+ * Code Sample: general usage
+ * <pre>
+ * \code
+ * // the date interval object which the DateIntervalFormat formats on
+ * // and parses into
+ * DateInterval* dtInterval = new DateInterval(1000*3600*24, 1000*3600*24*2);
+ * UErrorCode status = U_ZERO_ERROR;
+ * DateIntervalFormat* dtIntervalFmt = DateIntervalFormat::createInstance(

+ * FieldPosition pos = 0;
+ * // formatting

-/**
- * DateIntervalInfo is a public class for encapsulating localizable
- * date time interval patterns. It is used by DateIntervalFormat.
- *
- * <P>
- * For most users, ordinary use of DateIntervalFormat does not need to create
- * DateIntervalInfo object directly.
- * DateIntervalFormat will take care of it when creating a date interval
- * formatter when user pass in skeleton and locale.
- *
- * <P>
- * For power users, who want to create their own date interval patterns,
- * or want to re-set date interval patterns, they could do so by
- * directly creating DateIntervalInfo and manupulating it.
- *
- * <P>
- * Logically, the interval patterns are mappings
- * from (skeleton, the_largest_different_calendar_field)
- * to (date_interval_pattern).
- *
- * <P>
- * A skeleton
- * <ol>
- * <li>
- * only keeps the field pattern letter and ignores all other parts
- * in a pattern, such as space, punctuations, and string literals.
- * <li>
- * hides the order of fields.
- * <li>
- * might hide a field's pattern letter length.
- *
- * For those non-digit calendar fields, the pattern letter length is
- * important, such as MMM, MMMM, and MMMMM; EEE and EEEE,
- * and the field's pattern letter length is honored.
- *
- * For the digit calendar fields, such as M or MM, d or dd, yy or yyyy,
- * the field pattern length is ignored and the best match, which is defined
- * in date time patterns, will be returned without honor the field pattern
- * letter length in skeleton.
- * </ol>
- *
- * <P>
- * The calendar fields we support for interval formatting are:
- * year, month, date, day-of-week, am-pm, hour, hour-of-day, and minute.
- * Those calendar fields can be defined in the following order:
- * year > month > date > am-pm > hour > minute
- *
- * The largest different calendar fields between 2 calendars is the
- * first different calendar field in above order.
- *
- * For example: the largest different calendar fields between "Jan 10, 2007"
- * and "Feb 20, 2008" is year.
- *
- * <P>
- * There is a set of pre-defined static skeleton strings.
- * There are pre-defined interval patterns for those pre-defined skeletons
- * in locales' resource files.
- * For example, for a skeleton UDAT_YEAR_ABBR_MONTH_DAY, which is "yMMMd",
- * in en_US, if the largest different calendar field between date1 and date2
- * is "year", the date interval pattern is "MMM d, yyyy - MMM d, yyyy",
- * such as "Jan 10, 2007 - Jan 10, 2008".
- * If the largest different calendar field between date1 and date2 is "month",
- * the date interval pattern is "MMM d - MMM d, yyyy",
- * such as "Jan 10 - Feb 10, 2007".
- * If the largest different calendar field between date1 and date2 is "day",
- * the date interval pattern is ""MMM d-d, yyyy", such as "Jan 10-20, 2007".
- *
- * For date skeleton, the interval patterns when year, or month, or date is
- * different are defined in resource files.
- * For time skeleton, the interval patterns when am/pm, or hour, or minute is
- * different are defined in resource files.
- *
- *
- * <P>
- * There are 2 dates in interval pattern. For most locales, the first date
- * in an interval pattern is the earlier date. There might be a locale in which
- * the first date in an interval pattern is the later date.
- * We use fallback format for the default order for the locale.
- * For example, if the fallback format is "{0} - {1}", it means
- * the first date in the interval pattern for this locale is earlier date.
- * If the fallback format is "{1} - {0}", it means the first date is the
- * later date.
- * For a particular interval pattern, the default order can be overriden
- * by prefixing "latestFirst:" or "earliestFirst:" to the interval pattern.
- * For example, if the fallback format is "{0}-{1}",
- * but for skeleton "yMMMd", the interval pattern when day is different is
- * "latestFirst:d-d MMM yy", it means by default, the first date in interval
- * pattern is the earlier date. But for skeleton "yMMMd", when day is different,
- * the first date in "d-d MMM yy" is the later date.
- *
- * <P>
- * The recommended way to create a DateIntervalFormat object is to pass in
- * the locale.
- * By using a Locale parameter, the DateIntervalFormat object is
- * initialized with the pre-defined interval patterns for a given or
- * default locale.
- * <P>
- * Users can also create DateIntervalFormat object
- * by supplying their own interval patterns.
- * It provides flexibility for power users.
- *
- * <P>
- * After a DateIntervalInfo object is created, clients may modify
- * the interval patterns using setIntervalPattern function as so desired.
- * Currently, users can only set interval patterns when the following
- * calendar fields are different: ERA, YEAR, MONTH, DATE, DAY_OF_MONTH,
- * DAY_OF_WEEK, AM_PM, HOUR, HOUR_OF_DAY, and MINUTE.
- * Interval patterns when other calendar fields are different is not supported.
- * <P>
- * DateIntervalInfo objects are cloneable.
- * When clients obtain a DateIntervalInfo object,
- * they can feel free to modify it as necessary.
- * <P>
- * DateIntervalInfo are not expected to be subclassed.
- * Data for a calendar is loaded out of resource bundles.
- * To ICU 4.0, date interval patterns are only supported in Gregorian calendar.

+/**
+ * DateIntervalInfo is a public class for encapsulating localizable
+ * date time interval patterns. It is used by DateIntervalFormat.
+ *
+ * <P>
+ * For most users, ordinary use of DateIntervalFormat does not need to create
+ * DateIntervalInfo object directly.
+ * DateIntervalFormat will take care of it when creating a date interval
+ * formatter when user pass in skeleton and locale.
+ *
+ * <P>
+ * For power users, who want to create their own date interval patterns,
+ * or want to re-set date interval patterns, they could do so by
+ * directly creating DateIntervalInfo and manupulating it.
+ *
+ * <P>
+ * Logically, the interval patterns are mappings
+ * from (skeleton, the_largest_different_calendar_field)
+ * to (date_interval_pattern).
+ *
+ * <P>
+ * A skeleton
+ * <ol>
+ * <li>
+ * only keeps the field pattern letter and ignores all other parts
+ * in a pattern, such as space, punctuations, and string literals.
+ * <li>
+ * hides the order of fields.
+ * <li>
+ * might hide a field's pattern letter length.
+ *
+ * For those non-digit calendar fields, the pattern letter length is
+ * important, such as MMM, MMMM, and MMMMM; EEE and EEEE,
+ * and the field's pattern letter length is honored.
+ *
+ * For the digit calendar fields, such as M or MM, d or dd, yy or yyyy,
+ * the field pattern length is ignored and the best match, which is defined
+ * in date time patterns, will be returned without honor the field pattern
+ * letter length in skeleton.
+ * </ol>
+ *
+ * <P>
+ * The calendar fields we support for interval formatting are:
+ * year, month, date, day-of-week, am-pm, hour, hour-of-day, and minute.
+ * Those calendar fields can be defined in the following order:
+ * year > month > date > am-pm > hour > minute
+ *
+ * The largest different calendar fields between 2 calendars is the
+ * first different calendar field in above order.
+ *
+ * For example: the largest different calendar fields between "Jan 10, 2007"
+ * and "Feb 20, 2008" is year.
+ *
+ * <P>
+ * There is a set of pre-defined static skeleton strings.
+ * There are pre-defined interval patterns for those pre-defined skeletons
+ * in locales' resource files.
+ * For example, for a skeleton UDAT_YEAR_ABBR_MONTH_DAY, which is "yMMMd",
+ * in en_US, if the largest different calendar field between date1 and date2
+ * is "year", the date interval pattern is "MMM d, yyyy - MMM d, yyyy",
+ * such as "Jan 10, 2007 - Jan 10, 2008".
+ * If the largest different calendar field between date1 and date2 is "month",
+ * the date interval pattern is "MMM d - MMM d, yyyy",
+ * such as "Jan 10 - Feb 10, 2007".
+ * If the largest different calendar field between date1 and date2 is "day",
+ * the date interval pattern is ""MMM d-d, yyyy", such as "Jan 10-20, 2007".
+ *
+ * For date skeleton, the interval patterns when year, or month, or date is
+ * different are defined in resource files.
+ * For time skeleton, the interval patterns when am/pm, or hour, or minute is
+ * different are defined in resource files.
+ *
+ *
+ * <P>
+ * There are 2 dates in interval pattern. For most locales, the first date
+ * in an interval pattern is the earlier date. There might be a locale in which
+ * the first date in an interval pattern is the later date.
+ * We use fallback format for the default order for the locale.
+ * For example, if the fallback format is "{0} - {1}", it means
+ * the first date in the interval pattern for this locale is earlier date.
+ * If the fallback format is "{1} - {0}", it means the first date is the
+ * later date.
+ * For a particular interval pattern, the default order can be overriden
+ * by prefixing "latestFirst:" or "earliestFirst:" to the interval pattern.
+ * For example, if the fallback format is "{0}-{1}",
+ * but for skeleton "yMMMd", the interval pattern when day is different is
+ * "latestFirst:d-d MMM yy", it means by default, the first date in interval
+ * pattern is the earlier date. But for skeleton "yMMMd", when day is different,
+ * the first date in "d-d MMM yy" is the later date.
+ *
+ * <P>
+ * The recommended way to create a DateIntervalFormat object is to pass in
+ * the locale.
+ * By using a Locale parameter, the DateIntervalFormat object is
+ * initialized with the pre-defined interval patterns for a given or
+ * default locale.
+ * <P>
+ * Users can also create DateIntervalFormat object
+ * by supplying their own interval patterns.
+ * It provides flexibility for power users.
+ *
+ * <P>
+ * After a DateIntervalInfo object is created, clients may modify
+ * the interval patterns using setIntervalPattern function as so desired.
+ * Currently, users can only set interval patterns when the following
+ * calendar fields are different: ERA, YEAR, MONTH, DATE, DAY_OF_MONTH,
+ * DAY_OF_WEEK, AM_PM, HOUR, HOUR_OF_DAY, and MINUTE.
+ * Interval patterns when other calendar fields are different is not supported.
+ * <P>
+ * DateIntervalInfo objects are cloneable.
+ * When clients obtain a DateIntervalInfo object,
+ * they can feel free to modify it as necessary.
+ * <P>
+ * DateIntervalInfo are not expected to be subclassed.
+ * Data for a calendar is loaded out of resource bundles.
+ * To ICU 4.0, date interval patterns are only supported in Gregorian calendar.

- * <p>
- * <code>FieldPosition</code> keeps track of the position of the
- * field within the formatted output with two indices: the index
- * of the first character of the field and the index of the last
- * character of the field.
- *
- * <p>
- * One version of the <code>format</code> method in the various
- * <code>Format</code> classes requires a <code>FieldPosition</code>
- * object as an argument. You use this <code>format</code> method
- * to perform partial formatting or to get information about the
- * formatted output (such as the position of a field).
- *
- * The FieldPosition class is not suitable for subclassing.
- *
- * <p>
- * Below is an example of using <code>FieldPosition</code> to aid
- * alignment of an array of formatted floating-point numbers on
- * their decimal points:
- * <pre>
- * \code
- * double doubleNum[] = {123456789.0, -12345678.9, 1234567.89, -123456.789,
- * 12345.6789, -1234.56789, 123.456789, -12.3456789, 1.23456789};
- * int dNumSize = (int)(sizeof(doubleNum)/sizeof(double));
- *
- * UErrorCode status = U_ZERO_ERROR;
- * DecimalFormat* fmt = (DecimalFormat*) NumberFormat::createInstance(status);
- * fmt->setDecimalSeparatorAlwaysShown(true);
- *
- * const int tempLen = 20;
- * char temp[tempLen];
- *
- * for (int i=0; i<dNumSize; i++) {
- * FieldPosition pos(NumberFormat::INTEGER_FIELD);
- * UnicodeString buf;
- * char fmtText[tempLen];
- * ToCharString(fmt->format(doubleNum[i], buf, pos), fmtText);
- * for (int j=0; j<tempLen; j++) temp[j] = ' '; // clear with spaces
- * temp[__min(tempLen, tempLen-pos.getEndIndex())] = '\0';
- * cout << temp << fmtText << endl;
- * }
- * delete fmt;
- * \endcode
- * </pre>
- * <p>
- * The code will generate the following output:

-/**
- * Base class for all formats. This is an abstract base class which
- * specifies the protocol for classes which convert other objects or
- * values, such as numeric values and dates, and their string
- * representations. In some cases these representations may be
- * localized or contain localized characters or strings. For example,
- * a numeric formatter such as DecimalFormat may convert a numeric
- * value such as 12345 to the string "$12,345". It may also parse
- * the string back into a numeric value. A date and time formatter
- * like SimpleDateFormat may represent a specific date, encoded
- * numerically, as a string such as "Wednesday, February 26, 1997 AD".
- * <P>
- * Many of the concrete subclasses of Format employ the notion of
- * a pattern. A pattern is a string representation of the rules which
- * govern the interconversion between values and strings. For example,
- * a DecimalFormat object may be associated with the pattern
- * "$#,##0.00;($#,##0.00)", which is a common US English format for
- * currency values, yielding strings such as "$1,234.45" for 1234.45,
- * and "($987.65)" for 987.6543. The specific syntax of a pattern
- * is defined by each subclass.
- * <P>
- * Even though many subclasses use patterns, the notion of a pattern
- * is not inherent to Format classes in general, and is not part of
- * the explicit base class protocol.
- * <P>
- * Two complex formatting classes bear mentioning. These are
- * MessageFormat and ChoiceFormat. ChoiceFormat is a subclass of
- * NumberFormat which allows the user to format different number ranges
- * as strings. For instance, 0 may be represented as "no files", 1 as
- * "one file", and any number greater than 1 as "many files".
- * MessageFormat is a formatter which utilizes other Format objects to
- * format a string containing with multiple values. For instance,
- * A MessageFormat object might produce the string "There are no files
- * on the disk MyDisk on February 27, 1997." given the arguments 0,
- * "MyDisk", and the date value of 2/27/97. See the ChoiceFormat
- * and MessageFormat headers for further information.
- * <P>
- * If formatting is unsuccessful, a failing UErrorCode is returned when
- * the Format cannot format the type of object, otherwise if there is
- * something illformed about the the Unicode replacement character
- * 0xFFFD is returned.
- * <P>
- * If there is no match when parsing, a parse failure UErrorCode is
- * retured for methods which take no ParsePosition. For the method
- * that takes a ParsePosition, the index parameter is left unchanged.
- * <P>
- * <em>User subclasses are not supported.</em> While clients may write
- * subclasses, such code will not necessarily work and will not be
- * guaranteed to work stably from release to release.

-U_NAMESPACE_BEGIN
-
-/**
- * Concrete class which provides the standard calendar used by most of the world.
- * <P>
- * The standard (Gregorian) calendar has 2 eras, BC and AD.
- * <P>
- * This implementation handles a single discontinuity, which corresponds by default to
- * the date the Gregorian calendar was originally instituted (October 15, 1582). Not all
- * countries adopted the Gregorian calendar then, so this cutover date may be changed by
- * the caller.
- * <P>
- * Prior to the institution of the Gregorian Calendar, New Year's Day was March 25. To
- * avoid confusion, this Calendar always uses January 1. A manual adjustment may be made
- * if desired for dates that are prior to the Gregorian changeover and which fall
- * between January 1 and March 24.
- *
- * <p>Values calculated for the <code>WEEK_OF_YEAR</code> field range from 1 to
- * 53. Week 1 for a year is the first week that contains at least
- * <code>getMinimalDaysInFirstWeek()</code> days from that year. It thus
- * depends on the values of <code>getMinimalDaysInFirstWeek()</code>,
- * <code>getFirstDayOfWeek()</code>, and the day of the week of January 1.
- * Weeks between week 1 of one year and week 1 of the following year are
- * numbered sequentially from 2 to 52 or 53 (as needed).
- *
- * <p>For example, January 1, 1998 was a Thursday. If
- * <code>getFirstDayOfWeek()</code> is <code>MONDAY</code> and
- * <code>getMinimalDaysInFirstWeek()</code> is 4 (these are the values
- * reflecting ISO 8601 and many national standards), then week 1 of 1998 starts
- * on December 29, 1997, and ends on January 4, 1998. If, however,
- * <code>getFirstDayOfWeek()</code> is <code>SUNDAY</code>, then week 1 of 1998
- * starts on January 4, 1998, and ends on January 10, 1998; the first three days
- * of 1998 then are part of week 53 of 1997.
- *
- * <p>Example for using GregorianCalendar:
- * <pre>
- * \code
- * // get the supported ids for GMT-08:00 (Pacific Standard Time)
- * UErrorCode success = U_ZERO_ERROR;
- * const StringEnumeration *ids = TimeZone::createEnumeration(-8 * 60 * 60 * 1000);
- * // if no ids were returned, something is wrong. get out.
- * if (ids == 0 || ids->count(success) == 0) {
- * return;
- * }
- *
- * // begin output
- * cout << "Current Time" << endl;
- *
- * // create a Pacific Standard Time time zone
- * SimpleTimeZone* pdt = new SimpleTimeZone(-8 * 60 * 60 * 1000, ids->unext(NULL, success)));
- *
- * // set up rules for daylight savings time
- * pdt->setStartRule(Calendar::APRIL, 1, Calendar::SUNDAY, 2 * 60 * 60 * 1000);
- * pdt->setEndRule(Calendar::OCTOBER, -1, Calendar::SUNDAY, 2 * 60 * 60 * 1000);
- *
- * // create a GregorianCalendar with the Pacific Daylight time zone
- * // and the current date and time
- * Calendar* calendar = new GregorianCalendar( pdt, success );

+
+U_NAMESPACE_BEGIN
+
+/**
+ * Concrete class which provides the standard calendar used by most of the world.
+ * <P>
+ * The standard (Gregorian) calendar has 2 eras, BC and AD.
+ * <P>
+ * This implementation handles a single discontinuity, which corresponds by default to
+ * the date the Gregorian calendar was originally instituted (October 15, 1582). Not all
+ * countries adopted the Gregorian calendar then, so this cutover date may be changed by
+ * the caller.
+ * <P>
+ * Prior to the institution of the Gregorian Calendar, New Year's Day was March 25. To
+ * avoid confusion, this Calendar always uses January 1. A manual adjustment may be made
+ * if desired for dates that are prior to the Gregorian changeover and which fall
+ * between January 1 and March 24.
+ *
+ * <p>Values calculated for the <code>WEEK_OF_YEAR</code> field range from 1 to
+ * 53. Week 1 for a year is the first week that contains at least
+ * <code>getMinimalDaysInFirstWeek()</code> days from that year. It thus
+ * depends on the values of <code>getMinimalDaysInFirstWeek()</code>,
+ * <code>getFirstDayOfWeek()</code>, and the day of the week of January 1.
+ * Weeks between week 1 of one year and week 1 of the following year are
+ * numbered sequentially from 2 to 52 or 53 (as needed).
+ *
+ * <p>For example, January 1, 1998 was a Thursday. If
+ * <code>getFirstDayOfWeek()</code> is <code>MONDAY</code> and
+ * <code>getMinimalDaysInFirstWeek()</code> is 4 (these are the values
+ * reflecting ISO 8601 and many national standards), then week 1 of 1998 starts
+ * on December 29, 1997, and ends on January 4, 1998. If, however,
+ * <code>getFirstDayOfWeek()</code> is <code>SUNDAY</code>, then week 1 of 1998
+ * starts on January 4, 1998, and ends on January 10, 1998; the first three days
+ * of 1998 then are part of week 53 of 1997.
+ *
+ * <p>Example for using GregorianCalendar:
+ * <pre>
+ * \code
+ * // get the supported ids for GMT-08:00 (Pacific Standard Time)
+ * UErrorCode success = U_ZERO_ERROR;
+ * const StringEnumeration *ids = TimeZone::createEnumeration(-8 * 60 * 60 * 1000);
+ * // if no ids were returned, something is wrong. get out.
+ * if (ids == 0 || ids->count(success) == 0) {
+ * return;
+ * }
+ *
+ * // begin output
+ * cout << "Current Time" << endl;
+ *
+ * // create a Pacific Standard Time time zone
+ * SimpleTimeZone* pdt = new SimpleTimeZone(-8 * 60 * 60 * 1000, ids->unext(NULL, success)));
+ *
+ * // set up rules for daylight savings time
+ * pdt->setStartRule(Calendar::APRIL, 1, Calendar::SUNDAY, 2 * 60 * 60 * 1000);
+ * pdt->setEndRule(Calendar::OCTOBER, -1, Calendar::SUNDAY, 2 * 60 * 60 * 1000);

-/**
- * \file
- * \brief C++ API: Locale ID object.
- */
-
-/**
- * A <code>Locale</code> object represents a specific geographical, political,
- * or cultural region. An operation that requires a <code>Locale</code> to perform
- * its task is called <em>locale-sensitive</em> and uses the <code>Locale</code>
- * to tailor information for the user. For example, displaying a number
- * is a locale-sensitive operation--the number should be formatted
- * according to the customs/conventions of the user's native country,
- * region, or culture.
- *
- * The Locale class is not suitable for subclassing.
- *
- * <P>
- * You can create a <code>Locale</code> object using the constructor in
- * this class:
- * \htmlonly<blockquote>\endhtmlonly
- * <pre>
- * Locale( const char* language,
- * const char* country,
- * const char* variant);
- * </pre>
- * \htmlonly</blockquote>\endhtmlonly
- * The first argument to the constructors is a valid <STRONG>ISO
- * Language Code.</STRONG> These codes are the lower-case two-letter
- * codes as defined by ISO-639.
- * You can find a full list of these codes at:
- * <BR><a href ="http://www.loc.gov/standards/iso639-2/">
- * http://www.loc.gov/standards/iso639-2/</a>
- *
- * <P>
- * The second argument to the constructors is a valid <STRONG>ISO Country
- * Code.</STRONG> These codes are the upper-case two-letter codes
- * as defined by ISO-3166.
- * You can find a full list of these codes at a number of sites, such as:
- * <BR><a href="http://www.iso.org/iso/en/prods-services/iso3166ma/index.html">
- * http://www.iso.org/iso/en/prods-services/iso3166ma/index.html</a>
- *
- * <P>
- * The third constructor requires a third argument--the <STRONG>Variant.</STRONG>
- * The Variant codes are vendor and browser-specific.
- * For example, use REVISED for a langauge's revised script orthography, and POSIX for POSIX.
- * Where there are two variants, separate them with an underscore, and
- * put the most important one first. For
- * example, a Traditional Spanish collation might be referenced, with
- * "ES", "ES", "Traditional_POSIX".
- *
- * <P>
- * Because a <code>Locale</code> object is just an identifier for a region,
- * no validity check is performed when you construct a <code>Locale</code>.
- * If you want to see whether particular resources are available for the
- * <code>Locale</code> you construct, you must query those resources. For
- * example, ask the <code>NumberFormat</code> for the locales it supports
- * using its <code>getAvailableLocales</code> method.
- * <BR><STRONG>Note:</STRONG> When you ask for a resource for a particular
- * locale, you get back the best available match, not necessarily
- * precisely what you asked for. For more information, look at
- * <code>ResourceBundle</code>.
- *
- * <P>
- * The <code>Locale</code> class provides a number of convenient constants
- * that you can use to create <code>Locale</code> objects for commonly used
- * locales. For example, the following refers to a <code>Locale</code> object
- * for the United States:
- * \htmlonly<blockquote>\endhtmlonly
- * <pre>
- * Locale::getUS()
- * </pre>
- * \htmlonly</blockquote>\endhtmlonly
- *
- * <P>
- * Once you've created a <code>Locale</code> you can query it for information about
- * itself. Use <code>getCountry</code> to get the ISO Country Code and
- * <code>getLanguage</code> to get the ISO Language Code. You can
- * use <code>getDisplayCountry</code> to get the
- * name of the country suitable for displaying to the user. Similarly,
- * you can use <code>getDisplayLanguage</code> to get the name of
- * the language suitable for displaying to the user. Interestingly,
- * the <code>getDisplayXXX</code> methods are themselves locale-sensitive
- * and have two versions: one that uses the default locale and one
- * that takes a locale as an argument and displays the name or country in
- * a language appropriate to that locale.
- *
- * <P>
- * ICU provides a number of classes that perform locale-sensitive
- * operations. For example, the <code>NumberFormat</code> class formats
- * numbers, currency, or percentages in a locale-sensitive manner. Classes
- * such as <code>NumberFormat</code> have a number of convenience methods
- * for creating a default object of that type. For example, the
- * <code>NumberFormat</code> class provides these three convenience methods
- * for creating a default <code>NumberFormat</code> object:
- * \htmlonly<blockquote>\endhtmlonly
- * <pre>
- * UErrorCode success = U_ZERO_ERROR;
- * Locale myLocale;
- * NumberFormat *nf;
- *
- * nf = NumberFormat::createInstance( success ); delete nf;
- * nf = NumberFormat::createCurrencyInstance( success ); delete nf;
- * nf = NumberFormat::createPercentInstance( success ); delete nf;
- * </pre>
- * \htmlonly</blockquote>\endhtmlonly
- * Each of these methods has two variants; one with an explicit locale
- * and one without; the latter using the default locale.
- * \htmlonly<blockquote>\endhtmlonly
- * <pre>
- * nf = NumberFormat::createInstance( myLocale, success ); delete nf;
- * nf = NumberFormat::createCurrencyInstance( myLocale, success ); delete nf;
- * nf = NumberFormat::createPercentInstance( myLocale, success ); delete nf;
- * </pre>
- * \htmlonly</blockquote>\endhtmlonly
- * A <code>Locale</code> is the mechanism for identifying the kind of object
- * (<code>NumberFormat</code>) that you would like to get. The locale is
- * <STRONG>just</STRONG> a mechanism for identifying objects,
- * <STRONG>not</STRONG> a container for the objects themselves.
- *
- * <P>
- * Each class that performs locale-sensitive operations allows you
- * to get all the available objects of that type. You can sift
- * through these objects by language, country, or variant,
- * and use the display names to present a menu to the user.
- * For example, you can create a menu of all the collation objects
- * suitable for a given language. Such classes implement these
- * three class methods:
- * \htmlonly<blockquote>\endhtmlonly
- * <pre>
- * static Locale* getAvailableLocales(int32_t& numLocales)
- * static UnicodeString& getDisplayName(const Locale& objectLocale,
- * const Locale& displayLocale,
- * UnicodeString& displayName)
- * static UnicodeString& getDisplayName(const Locale& objectLocale,
- * UnicodeString& displayName)
- * </pre>
- * \htmlonly</blockquote>\endhtmlonly

+ */
+
+/**
+ * A <code>Locale</code> object represents a specific geographical, political,
+ * or cultural region. An operation that requires a <code>Locale</code> to perform
+ * its task is called <em>locale-sensitive</em> and uses the <code>Locale</code>
+ * to tailor information for the user. For example, displaying a number
+ * is a locale-sensitive operation--the number should be formatted
+ * according to the customs/conventions of the user's native country,
+ * region, or culture.
+ *
+ * The Locale class is not suitable for subclassing.
+ *
+ * <P>
+ * You can create a <code>Locale</code> object using the constructor in
+ * this class:
+ * \htmlonly<blockquote>\endhtmlonly
+ * <pre>
+ * Locale( const char* language,
+ * const char* country,
+ * const char* variant);
+ * </pre>
+ * \htmlonly</blockquote>\endhtmlonly
+ * The first argument to the constructors is a valid <STRONG>ISO
+ * Language Code.</STRONG> These codes are the lower-case two-letter
+ * codes as defined by ISO-639.
+ * You can find a full list of these codes at:
+ * <BR><a href ="http://www.loc.gov/standards/iso639-2/">
+ * http://www.loc.gov/standards/iso639-2/</a>
+ *
+ * <P>
+ * The second argument to the constructors is a valid <STRONG>ISO Country
+ * Code.</STRONG> These codes are the upper-case two-letter codes
+ * as defined by ISO-3166.
+ * You can find a full list of these codes at a number of sites, such as:
+ * <BR><a href="http://www.iso.org/iso/en/prods-services/iso3166ma/index.html">
+ * http://www.iso.org/iso/en/prods-services/iso3166ma/index.html</a>
+ *
+ * <P>
+ * The third constructor requires a third argument--the <STRONG>Variant.</STRONG>
+ * The Variant codes are vendor and browser-specific.
+ * For example, use REVISED for a langauge's revised script orthography, and POSIX for POSIX.
+ * Where there are two variants, separate them with an underscore, and
+ * put the most important one first. For
+ * example, a Traditional Spanish collation might be referenced, with
+ * "ES", "ES", "Traditional_POSIX".
+ *
+ * <P>
+ * Because a <code>Locale</code> object is just an identifier for a region,
+ * no validity check is performed when you construct a <code>Locale</code>.
+ * If you want to see whether particular resources are available for the
+ * <code>Locale</code> you construct, you must query those resources. For
+ * example, ask the <code>NumberFormat</code> for the locales it supports
+ * using its <code>getAvailableLocales</code> method.
+ * <BR><STRONG>Note:</STRONG> When you ask for a resource for a particular
+ * locale, you get back the best available match, not necessarily
+ * precisely what you asked for. For more information, look at
+ * <code>ResourceBundle</code>.
+ *
+ * <P>
+ * The <code>Locale</code> class provides a number of convenient constants
+ * that you can use to create <code>Locale</code> objects for commonly used
+ * locales. For example, the following refers to a <code>Locale</code> object
+ * for the United States:
+ * \htmlonly<blockquote>\endhtmlonly
+ * <pre>
+ * Locale::getUS()
+ * </pre>
+ * \htmlonly</blockquote>\endhtmlonly
+ *
+ * <P>
+ * Once you've created a <code>Locale</code> you can query it for information about
+ * itself. Use <code>getCountry</code> to get the ISO Country Code and
+ * <code>getLanguage</code> to get the ISO Language Code. You can
+ * use <code>getDisplayCountry</code> to get the
+ * name of the country suitable for displaying to the user. Similarly,
+ * you can use <code>getDisplayLanguage</code> to get the name of
+ * the language suitable for displaying to the user. Interestingly,
+ * the <code>getDisplayXXX</code> methods are themselves locale-sensitive
+ * and have two versions: one that uses the default locale and one
+ * that takes a locale as an argument and displays the name or country in
+ * a language appropriate to that locale.
+ *
+ * <P>
+ * ICU provides a number of classes that perform locale-sensitive
+ * operations. For example, the <code>NumberFormat</code> class formats
+ * numbers, currency, or percentages in a locale-sensitive manner. Classes
+ * such as <code>NumberFormat</code> have a number of convenience methods
+ * for creating a default object of that type. For example, the
+ * <code>NumberFormat</code> class provides these three convenience methods
+ * for creating a default <code>NumberFormat</code> object:
+ * \htmlonly<blockquote>\endhtmlonly
+ * <pre>
+ * UErrorCode success = U_ZERO_ERROR;
+ * Locale myLocale;
+ * NumberFormat *nf;
+ *
+ * nf = NumberFormat::createInstance( success ); delete nf;
+ * nf = NumberFormat::createCurrencyInstance( success ); delete nf;
+ * nf = NumberFormat::createPercentInstance( success ); delete nf;
+ * </pre>
+ * \htmlonly</blockquote>\endhtmlonly
+ * Each of these methods has two variants; one with an explicit locale
+ * and one without; the latter using the default locale.
+ * \htmlonly<blockquote>\endhtmlonly
+ * <pre>
+ * nf = NumberFormat::createInstance( myLocale, success ); delete nf;
+ * nf = NumberFormat::createCurrencyInstance( myLocale, success ); delete nf;
+ * nf = NumberFormat::createPercentInstance( myLocale, success ); delete nf;
+ * </pre>
+ * \htmlonly</blockquote>\endhtmlonly
+ * A <code>Locale</code> is the mechanism for identifying the kind of object
+ * (<code>NumberFormat</code>) that you would like to get. The locale is
+ * <STRONG>just</STRONG> a mechanism for identifying objects,
+ * <STRONG>not</STRONG> a container for the objects themselves.
+ *
+ * <P>

-/**
- *
- * A MessageFormat produces concatenated messages in a
- * language-neutral way. It should be used for all string
- * concatenations that are visible to end users.
- * <P>
- * A MessageFormat contains an array of <EM>subformats</EM> arranged
- * within a <EM>template string</EM>. Together, the subformats and
- * template string determine how the MessageFormat will operate during
- * formatting and parsing.
- * <P>
- * Typically, both the subformats and the template string are
- * specified at once in a <EM>pattern</EM>. By using different
- * patterns for different locales, messages may be localized.
- * <P>
- * During formatting, the MessageFormat takes an array of arguments
- * and produces a user-readable string. Each argument is a
- * Formattable object; they may be passed in in an array, or as a
- * single Formattable object which itself contains an array. Each
- * argument is matched up with its corresponding subformat, which then
- * formats it into a string. The resultant strings are then assembled
- * within the string template of the MessageFormat to produce the
- * final output string.
- * <p>
- * <strong>Note:</strong>
- * In ICU 4.0 MessageFormat supports named arguments. If a named argument
- * is used, all arguments must be named. Names start with a character in
- * <code>UCHAR_ID_START</code> and continue with characters in
- * <code>UCHARID_CONTINUE</code>, in particular they do not start with a digit.
- * If named arguments are used, {@link #usesNamedArguments()} will return true.
- * <p>
- * The other new methods supporting named arguments are
- * {@link #getFormatNames(UErrorCode& status)},
- * {@link #getFormat(const UnicodeString& formatName, UErrorCode& status)}
- * {@link #setFormat(const UnicodeString& formatName, const Format& format, UErrorCode& status)},
- * {@link #adoptFormat(const UnicodeString& formatName, Format* formatToAdopt, UErrorCode& status)},
- * {@link #format(const Formattable* arguments, const UnicodeString *argumentNames, int32_t cnt, UnicodeString& appendTo, FieldPosition& status, int32_t recursionProtection, UErrorCode& success)},
- * {@link #format(const UnicodeString* argumentNames, const Formattable* arguments, int32_t count, UnicodeString& appendTo,UErrorCode& status)}.
- * These methods are all compatible with patterns that do not used named arguments--
- * in these cases the keys in the input or output use <code>UnicodeString</code>s
- * that name the argument indices, e.g. "0", "1", "2"... etc.
- * <p>
- * When named arguments are used, certain methods on MessageFormat that take or
- * return arrays do not perform any action, since it is not possible to
- * identify positions in an array using a name. UErrorCode is set to
- * U_ARGUMENT_TYPE_MISMATCH if there is a status/success field in the method.
- * These methods are
- * {@link #adoptFormats(Format** newFormats, int32_t count)},
- * {@link #setFormats(const Format** newFormats,int32_t count)},
- * {@link #adoptFormat(int32_t n, Format *newFormat)},
- * {@link #getFormats(int32_t& cnt)},
- * {@link #format(const Formattable* source,int32_t cnt,UnicodeString& appendTo, FieldPosition& ignore, UErrorCode& success)},
- * {@link #format(const UnicodeString& pattern,const Formattable* arguments,int32_t cnt,UnicodeString& appendTo,UErrorCode& success)},
- * {@link #format(const Formattable& source, UnicodeString& appendTo,FieldPosition& ignore, UErrorCode& success)},
- * {@link #format(const Formattable* arguments, int32_t cnt, UnicodeString& appendTo, FieldPosition& status, int32_t recursionProtection,UErrorCode& success)},
- * {@link #parse(const UnicodeString& source, ParsePosition& pos,int32_t& count)},
- * {@link #parse(const UnicodeString& source, int32_t& cnt, UErrorCode& status)}
- * <p>
- *
- * <P>
- * During parsing, an input string is matched against the string
- * template of the MessageFormat to produce an array of Formattable
- * objects. Plain text of the template string is matched directly
- * against intput text. At each position in the template string where
- * a subformat is located, the subformat is called to parse the
- * corresponding segment of input text to produce an output argument.
- * In this way, an array of arguments is created which together
- * constitute the parse result.
- * <P>
- * Parsing may fail or produce unexpected results in a number of
- * circumstances.
- * <UL>
- * <LI>If one of the arguments does not occur in the pattern, it
- * will be returned as a default Formattable.
- * <LI>If the format of an argument is loses information, such as with
- * a choice format where a large number formats to "many", then the
- * parse may not correspond to the originally formatted argument.
- * <LI>MessageFormat does not handle ChoiceFormat recursion during
- * parsing; such parses will fail.
- * <LI>Parsing will not always find a match (or the correct match) if
- * some part of the parse is ambiguous. For example, if the pattern
- * "{1},{2}" is used with the string arguments {"a,b", "c"}, it will
- * format as "a,b,c". When the result is parsed, it will return {"a",
- * "b,c"}.
- * <LI>If a single argument is formatted more than once in the string,
- * then the rightmost subformat in the pattern string will produce the
- * parse result; prior subformats with the same argument index will
- * have no effect.
- * </UL>
- * Here are some examples of usage:
- * <P>
- * Example 1:
- * <pre>
- * \code
- * UErrorCode success = U_ZERO_ERROR;
- * GregorianCalendar cal(success);
- * Formattable arguments[] = {
- * 7L,
- * Formattable( (Date) cal.getTime(success), Formattable::kIsDate),
- * "a disturbance in the Force"
- * };
- *
- * UnicodeString result;
- * MessageFormat::format(
- * "At {1,time} on {1,date}, there was {2} on planet {0,number}.",
- * arguments, 3, result, success );
- *
- * cout << "result: " << result << endl;
- * //<output>: At 4:34:20 PM on 23-Mar-98, there was a disturbance
- * // in the Force on planet 7.
- * \endcode
- * </pre>
- * Typically, the message format will come from resources, and the
- * arguments will be dynamically set at runtime.
- * <P>
- * Example 2:
- * <pre>
- * \code
- * success = U_ZERO_ERROR;
- * Formattable testArgs[] = {3L, "MyDisk"};
- *
- * MessageFormat form(
- * "The disk \"{1}\" contains {0} file(s).", success );
- *
- * UnicodeString string;
- * FieldPosition fpos = 0;
- * cout << "format: " << form.format(testArgs, 2, string, fpos, success ) << endl;
- *
- * // output, with different testArgs:
- * // output: The disk "MyDisk" contains 0 file(s).
- * // output: The disk "MyDisk" contains 1 file(s).
- * // output: The disk "MyDisk" contains 1,273 file(s).
- * \endcode
- * </pre>
- *
- * The pattern is of the following form. Legend:
- * <pre>
- * \code
- * {optional item}
- * (group that may be repeated)*
- * \endcode
- * </pre>
- * Do not confuse optional items with items inside quotes braces, such
- * as this: "{". Quoted braces are literals.
- * <pre>
- * \code
- * messageFormatPattern := string ( "{" messageFormatElement "}" string )*
- *
- * messageFormatElement := argumentIndex | argumentName { "," elementFormat }
- *
- * elementFormat := "time" { "," datetimeStyle }
- * | "date" { "," datetimeStyle }
- * | "number" { "," numberStyle }
- * | "choice" "," choiceStyle
- *
- * datetimeStyle := "short"
- * | "medium"
- * | "long"
- * | "full"
- * | dateFormatPattern
- *
- * numberStyle := "currency"
- * | "percent"
- * | "integer"
- * | numberFormatPattern
- *
- * choiceStyle := choiceFormatPattern
- *
- * pluralStyle := pluralFormatPattern
- * \endcode
- * </pre>
- * If there is no elementFormat, then the argument must be a string,
- * which is substituted. If there is no dateTimeStyle or numberStyle,
- * then the default format is used (e.g. NumberFormat::createInstance(),
- * DateFormat::createTimeInstance(DateFormat::kDefault, ...) or DateFormat::createDateInstance(DateFormat::kDefault, ...). For
- * a ChoiceFormat, the pattern must always be specified, since there
- * is no default.
- * <P>
- * In strings, single quotes can be used to quote syntax characters.
- * A literal single quote is represented by '', both within and outside
- * of single-quoted segments. Inside a
- * messageFormatElement, quotes are <EM>not</EM> removed. For example,
- * {1,number,$'#',##} will produce a number format with the pound-sign
- * quoted, with a result such as: "$#31,45".
- * <P>
- * If a pattern is used, then unquoted braces in the pattern, if any,
- * must match: that is, "ab {0} de" and "ab '}' de" are ok, but "ab
- * {0'}' de" and "ab } de" are not.
- * <p>
- * <dl><dt><b>Warning:</b><dd>The rules for using quotes within message
- * format patterns unfortunately have shown to be somewhat confusing.
- * In particular, it isn't always obvious to localizers whether single
- * quotes need to be doubled or not. Make sure to inform localizers about
- * the rules, and tell them (for example, by using comments in resource
- * bundle source files) which strings will be processed by MessageFormat.
- * Note that localizers may need to use single quotes in translated
- * strings where the original version doesn't have them.
- * <br>Note also that the simplest way to avoid the problem is to
- * use the real apostrophe (single quote) character U+2019 (') for
- * human-readable text, and to use the ASCII apostrophe (U+0027 ' )
- * only in program syntax, like quoting in MessageFormat.
- * See the annotations for U+0027 Apostrophe in The Unicode Standard.</p>
- * </dl>
- * <P>
- * The argumentIndex is a non-negative integer, which corresponds to the
- * index of the arguments presented in an array to be formatted. The
- * first argument has argumentIndex 0.
- * <P>
- * It is acceptable to have unused arguments in the array. With missing
- * arguments or arguments that are not of the right class for the
- * specified format, a failing UErrorCode result is set.
- * <P>
- * For more sophisticated patterns, you can use a ChoiceFormat to get
- * output:
- * <pre>
- * \code
- * UErrorCode success = U_ZERO_ERROR;
- * MessageFormat* form("The disk \"{1}\" contains {0}.", success);
- * double filelimits[] = {0,1,2};
- * UnicodeString filepart[] = {"no files","one file","{0,number} files"};
- * ChoiceFormat* fileform = new ChoiceFormat(filelimits, filepart, 3);
- * form.setFormat(1, *fileform); // NOT zero, see below
- *
- * Formattable testArgs[] = {1273L, "MyDisk"};
- *
- * UnicodeString string;
- * FieldPosition fpos = 0;
- * cout << form.format(testArgs, 2, string, fpos, success) << endl;
- *

- * You can either do this programmatically, as in the above example,

- * <P>
- * <EM>Note:</EM> As we see above, the string produced by a ChoiceFormat in
- * MessageFormat is treated specially; occurences of '{' are used to
- * indicated subformats, and cause recursion. If you create both a
- * MessageFormat and ChoiceFormat programmatically (instead of using
- * the string patterns), then be careful not to produce a format that
- * recurses on itself, which will cause an infinite loop.
- * <P>
- * <EM>Note:</EM> Subformats are numbered by their order in the pattern.
- * This is <EM>not</EM> the same as the argumentIndex.
- * <pre>
- * \code
- * For example: with "abc{2}def{3}ghi{0}...",
- *
- * format0 affects the first variable {2}
- * format1 affects the second variable {3}
- * format2 affects the second variable {0}
- * \endcode

- * <p><em>User subclasses are not supported.</em> While clients may write
- * subclasses, such code will not necessarily work and will not be

+/**
+ *
+ * A MessageFormat produces concatenated messages in a
+ * language-neutral way. It should be used for all string
+ * concatenations that are visible to end users.
+ * <P>
+ * A MessageFormat contains an array of <EM>subformats</EM> arranged
+ * within a <EM>template string</EM>. Together, the subformats and
+ * template string determine how the MessageFormat will operate during
+ * formatting and parsing.
+ * <P>
+ * Typically, both the subformats and the template string are
+ * specified at once in a <EM>pattern</EM>. By using different
+ * patterns for different locales, messages may be localized.
+ * <P>
+ * During formatting, the MessageFormat takes an array of arguments
+ * and produces a user-readable string. Each argument is a
+ * Formattable object; they may be passed in in an array, or as a
+ * single Formattable object which itself contains an array. Each
+ * argument is matched up with its corresponding subformat, which then
+ * formats it into a string. The resultant strings are then assembled
+ * within the string template of the MessageFormat to produce the
+ * final output string.
+ * <p>
+ * <strong>Note:</strong>
+ * In ICU 4.0 MessageFormat supports named arguments. If a named argument
+ * is used, all arguments must be named. Names start with a character in
+ * <code>UCHAR_ID_START</code> and continue with characters in
+ * <code>UCHARID_CONTINUE</code>, in particular they do not start with a digit.
+ * If named arguments are used, {@link #usesNamedArguments()} will return true.
+ * <p>
+ * The other new methods supporting named arguments are
+ * {@link #getFormatNames(UErrorCode& status)},
+ * {@link #getFormat(const UnicodeString& formatName, UErrorCode& status)}
+ * {@link #setFormat(const UnicodeString& formatName, const Format& format, UErrorCode& status)},
+ * {@link #adoptFormat(const UnicodeString& formatName, Format* formatToAdopt, UErrorCode& status)},
+ * {@link #format(const Formattable* arguments, const UnicodeString *argumentNames, int32_t cnt, UnicodeString& appendTo, FieldPosition& status, int32_t recursionProtection, UErrorCode& success)},
+ * {@link #format(const UnicodeString* argumentNames, const Formattable* arguments, int32_t count, UnicodeString& appendTo,UErrorCode& status)}.
+ * These methods are all compatible with patterns that do not used named arguments--
+ * in these cases the keys in the input or output use <code>UnicodeString</code>s
+ * that name the argument indices, e.g. "0", "1", "2"... etc.
+ * <p>
+ * When named arguments are used, certain methods on MessageFormat that take or
+ * return arrays do not perform any action, since it is not possible to
+ * identify positions in an array using a name. UErrorCode is set to
+ * U_ARGUMENT_TYPE_MISMATCH if there is a status/success field in the method.
+ * These methods are
+ * {@link #adoptFormats(Format** newFormats, int32_t count)},
+ * {@link #setFormats(const Format** newFormats,int32_t count)},
+ * {@link #adoptFormat(int32_t n, Format *newFormat)},

+ * <p>
+ *
+ * <P>
+ * During parsing, an input string is matched against the string
+ * template of the MessageFormat to produce an array of Formattable
+ * objects. Plain text of the template string is matched directly
+ * against intput text. At each position in the template string where
+ * a subformat is located, the subformat is called to parse the
+ * corresponding segment of input text to produce an output argument.
+ * In this way, an array of arguments is created which together
+ * constitute the parse result.
+ * <P>
+ * Parsing may fail or produce unexpected results in a number of
+ * circumstances.
+ * <UL>
+ * <LI>If one of the arguments does not occur in the pattern, it
+ * will be returned as a default Formattable.
+ * <LI>If the format of an argument is loses information, such as with
+ * a choice format where a large number formats to "many", then the
+ * parse may not correspond to the originally formatted argument.
+ * <LI>MessageFormat does not handle ChoiceFormat recursion during
+ * parsing; such parses will fail.
+ * <LI>Parsing will not always find a match (or the correct match) if
+ * some part of the parse is ambiguous. For example, if the pattern
+ * "{1},{2}" is used with the string arguments {"a,b", "c"}, it will
+ * format as "a,b,c". When the result is parsed, it will return {"a",
+ * "b,c"}.
+ * <LI>If a single argument is formatted more than once in the string,
+ * then the rightmost subformat in the pattern string will produce the
+ * parse result; prior subformats with the same argument index will
+ * have no effect.
+ * </UL>
+ * Here are some examples of usage:
+ * <P>
+ * Example 1:
+ * <pre>
+ * \code
+ * UErrorCode success = U_ZERO_ERROR;
+ * GregorianCalendar cal(success);
+ * Formattable arguments[] = {
+ * 7L,
+ * Formattable( (Date) cal.getTime(success), Formattable::kIsDate),
+ * "a disturbance in the Force"
+ * };
+ *
+ * UnicodeString result;
+ * MessageFormat::format(
+ * "At {1,time} on {1,date}, there was {2} on planet {0,number}.",
+ * arguments, 3, result, success );
+ *
+ * cout << "result: " << result << endl;
+ * //<output>: At 4:34:20 PM on 23-Mar-98, there was a disturbance
+ * // in the Force on planet 7.
+ * \endcode
+ * </pre>
+ * Typically, the message format will come from resources, and the
+ * arguments will be dynamically set at runtime.
+ * <P>
+ * Example 2:
+ * <pre>
+ * \code
+ * success = U_ZERO_ERROR;
+ * Formattable testArgs[] = {3L, "MyDisk"};
+ *
+ * MessageFormat form(
+ * "The disk \"{1}\" contains {0} file(s).", success );
+ *
+ * UnicodeString string;
+ * FieldPosition fpos = 0;
+ * cout << "format: " << form.format(testArgs, 2, string, fpos, success ) << endl;
+ *
+ * // output, with different testArgs:
+ * // output: The disk "MyDisk" contains 0 file(s).
+ * // output: The disk "MyDisk" contains 1 file(s).
+ * // output: The disk "MyDisk" contains 1,273 file(s).
+ * \endcode
+ * </pre>
+ *
+ * The pattern is of the following form. Legend:
+ * <pre>
+ * \code
+ * {optional item}
+ * (group that may be repeated)*
+ * \endcode
+ * </pre>
+ * Do not confuse optional items with items inside quotes braces, such
+ * as this: "{". Quoted braces are literals.
+ * <pre>
+ * \code
+ * messageFormatPattern := string ( "{" messageFormatElement "}" string )*
+ *
+ * messageFormatElement := argumentIndex | argumentName { "," elementFormat }
+ *
+ * elementFormat := "time" { "," datetimeStyle }
+ * | "date" { "," datetimeStyle }
+ * | "number" { "," numberStyle }
+ * | "choice" "," choiceStyle
+ *
+ * datetimeStyle := "short"
+ * | "medium"
+ * | "long"
+ * | "full"
+ * | dateFormatPattern
+ *
+ * numberStyle := "currency"
+ * | "percent"
+ * | "integer"
+ * | numberFormatPattern
+ *
+ * choiceStyle := choiceFormatPattern
+ *
+ * pluralStyle := pluralFormatPattern
+ * \endcode
+ * </pre>
+ * If there is no elementFormat, then the argument must be a string,
+ * which is substituted. If there is no dateTimeStyle or numberStyle,
+ * then the default format is used (e.g. NumberFormat::createInstance(),
+ * DateFormat::createTimeInstance(DateFormat::kDefault, ...) or DateFormat::createDateInstance(DateFormat::kDefault, ...). For
+ * a ChoiceFormat, the pattern must always be specified, since there
+ * is no default.
+ * <P>
+ * In strings, single quotes can be used to quote syntax characters.
+ * A literal single quote is represented by '', both within and outside
+ * of single-quoted segments. Inside a
+ * messageFormatElement, quotes are <EM>not</EM> removed. For example,
+ * {1,number,$'#',##} will produce a number format with the pound-sign
+ * quoted, with a result such as: "$#31,45".
+ * <P>
+ * If a pattern is used, then unquoted braces in the pattern, if any,
+ * must match: that is, "ab {0} de" and "ab '}' de" are ok, but "ab
+ * {0'}' de" and "ab } de" are not.
+ * <p>
+ * <dl><dt><b>Warning:</b><dd>The rules for using quotes within message
+ * format patterns unfortunately have shown to be somewhat confusing.
+ * In particular, it isn't always obvious to localizers whether single
+ * quotes need to be doubled or not. Make sure to inform localizers about
+ * the rules, and tell them (for example, by using comments in resource
+ * bundle source files) which strings will be processed by MessageFormat.
+ * Note that localizers may need to use single quotes in translated
+ * strings where the original version doesn't have them.
+ * <br>Note also that the simplest way to avoid the problem is to
+ * use the real apostrophe (single quote) character U+2019 (') for
+ * human-readable text, and to use the ASCII apostrophe (U+0027 ' )
+ * only in program syntax, like quoting in MessageFormat.
+ * See the annotations for U+0027 Apostrophe in The Unicode Standard.</p>
+ * </dl>
+ * <P>
+ * The argumentIndex is a non-negative integer, which corresponds to the
+ * index of the arguments presented in an array to be formatted. The
+ * first argument has argumentIndex 0.
+ * <P>
+ * It is acceptable to have unused arguments in the array. With missing
+ * arguments or arguments that are not of the right class for the
+ * specified format, a failing UErrorCode result is set.
+ * <P>
+ * For more sophisticated patterns, you can use a ChoiceFormat to get
+ * output:
+ * <pre>
+ * \code
+ * UErrorCode success = U_ZERO_ERROR;
+ * MessageFormat* form("The disk \"{1}\" contains {0}.", success);
+ * double filelimits[] = {0,1,2};
+ * UnicodeString filepart[] = {"no files","one file","{0,number} files"};
+ * ChoiceFormat* fileform = new ChoiceFormat(filelimits, filepart, 3);
+ * form.setFormat(1, *fileform); // NOT zero, see below
+ *
+ * Formattable testArgs[] = {1273L, "MyDisk"};
+ *
+ * UnicodeString string;
+ * FieldPosition fpos = 0;
+ * cout << form.format(testArgs, 2, string, fpos, success) << endl;
+ *
+ * // output, with different testArgs
+ * // output: The disk "MyDisk" contains no files.
+ * // output: The disk "MyDisk" contains one file.
+ * // output: The disk "MyDisk" contains 1,273 files.
+ * \endcode
+ * </pre>
+ * You can either do this programmatically, as in the above example,
+ * or by using a pattern (see ChoiceFormat for more information) as in:
+ * <pre>
+ * \code
+ * form.applyPattern(
+ * "There {0,choice,0#are no files|1#is one file|1<are {0,number,integer} files}.");
+ * \endcode
+ * </pre>
+ * <P>
+ * <EM>Note:</EM> As we see above, the string produced by a ChoiceFormat in
+ * MessageFormat is treated specially; occurences of '{' are used to
+ * indicated subformats, and cause recursion. If you create both a
+ * MessageFormat and ChoiceFormat programmatically (instead of using
+ * the string patterns), then be careful not to produce a format that
+ * recurses on itself, which will cause an infinite loop.
+ * <P>
+ * <EM>Note:</EM> Subformats are numbered by their order in the pattern.
+ * This is <EM>not</EM> the same as the argumentIndex.
+ * <pre>
+ * \code
+ * For example: with "abc{2}def{3}ghi{0}...",
+ *
+ * format0 affects the first variable {2}
+ * format1 affects the second variable {3}
+ * format2 affects the second variable {0}
+ * \endcode
+ * </pre>
+ *
+ * <p><em>User subclasses are not supported.</em> While clients may write
+ * subclasses, such code will not necessarily work and will not be

-/**
- * The Normalizer class supports the standard normalization forms described in
- * <a href="http://www.unicode.org/unicode/reports/tr15/" target="unicode">
- * Unicode Standard Annex #15: Unicode Normalization Forms</a>.
- *
- * The Normalizer class consists of two parts:
- * - static functions that normalize strings or test if strings are normalized
- * - a Normalizer object is an iterator that takes any kind of text and
- * provides iteration over its normalized form
- *
- * The Normalizer class is not suitable for subclassing.
- *
- * The static functions are basically wrappers around the C implementation,
- * using UnicodeString instead of UChar*.
- * For basic information about normalization forms and details about the C API
- * please see the documentation in unorm.h.
- *
- * The iterator API with the Normalizer constructors and the non-static functions
- * uses a CharacterIterator as input. It is possible to pass a string which
- * is then internally wrapped in a CharacterIterator.
- * The input text is not normalized all at once, but incrementally where needed
- * (providing efficient random access).
- * This allows to pass in a large text but spend only a small amount of time
- * normalizing a small part of that text.
- * However, if the entire text is normalized, then the iterator will be
- * slower than normalizing the entire text at once and iterating over the result.
- * A possible use of the Normalizer iterator is also to report an index into the
- * original text that is close to where the normalized characters come from.
- *
- * <em>Important:</em> The iterator API was cleaned up significantly for ICU 2.0.
- * The earlier implementation reported the getIndex() inconsistently,
- * and previous() could not be used after setIndex(), next(), first(), and current().
- *
- * Normalizer allows to start normalizing from anywhere in the input text by
- * calling setIndexOnly(), first(), or last().
- * Without calling any of these, the iterator will start at the beginning of the text.
- *
- * At any time, next() returns the next normalized code point (UChar32),
- * with post-increment semantics (like CharacterIterator::next32PostInc()).
- * previous() returns the previous normalized code point (UChar32),
- * with pre-decrement semantics (like CharacterIterator::previous32()).
- *
- * current() returns the current code point
- * (respectively the one at the newly set index) without moving
- * the getIndex(). Note that if the text at the current position
- * needs to be normalized, then these functions will do that.
- * (This is why current() is not const.)
- * It is more efficient to call setIndexOnly() instead, which does not
- * normalize.
- *
- * getIndex() always refers to the position in the input text where the normalized
- * code points are returned from. It does not always change with each returned
- * code point.
- * The code point that is returned from any of the functions
- * corresponds to text at or after getIndex(), according to the
- * function's iteration semantics (post-increment or pre-decrement).
- *
- * next() returns a code point from at or after the getIndex()
- * from before the next() call. After the next() call, the getIndex()
- * might have moved to where the next code point will be returned from
- * (from a next() or current() call).
- * This is semantically equivalent to array access with array[index++]
- * (post-increment semantics).
- *
- * previous() returns a code point from at or after the getIndex()
- * from after the previous() call.
- * This is semantically equivalent to array access with array[--index]
- * (pre-decrement semantics).
- *
- * Internally, the Normalizer iterator normalizes a small piece of text
- * starting at the getIndex() and ending at a following "safe" index.
- * The normalized results is stored in an internal string buffer, and
- * the code points are iterated from there.
- * With multiple iteration calls, this is repeated until the next piece
- * of text needs to be normalized, and the getIndex() needs to be moved.
- *
- * The following "safe" index, the internal buffer, and the secondary
- * iteration index into that buffer are not exposed on the API.
- * This also means that it is currently not practical to return to
- * a particular, arbitrary position in the text because one would need to
- * know, and be able to set, in addition to the getIndex(), at least also the
- * current index into the internal buffer.
- * It is currently only possible to observe when getIndex() changes
- * (with careful consideration of the iteration semantics),
- * at which time the internal index will be 0.
- * For example, if getIndex() is different after next() than before it,
- * then the internal index is 0 and one can return to this getIndex()
- * later with setIndexOnly().

+/**
+ * The Normalizer class supports the standard normalization forms described in
+ * <a href="http://www.unicode.org/unicode/reports/tr15/" target="unicode">
+ * Unicode Standard Annex #15: Unicode Normalization Forms</a>.
+ *
+ * The Normalizer class consists of two parts:
+ * - static functions that normalize strings or test if strings are normalized
+ * - a Normalizer object is an iterator that takes any kind of text and
+ * provides iteration over its normalized form
+ *
+ * The Normalizer class is not suitable for subclassing.
+ *
+ * The static functions are basically wrappers around the C implementation,
+ * using UnicodeString instead of UChar*.
+ * For basic information about normalization forms and details about the C API
+ * please see the documentation in unorm.h.
+ *
+ * The iterator API with the Normalizer constructors and the non-static functions
+ * uses a CharacterIterator as input. It is possible to pass a string which
+ * is then internally wrapped in a CharacterIterator.
+ * The input text is not normalized all at once, but incrementally where needed
+ * (providing efficient random access).
+ * This allows to pass in a large text but spend only a small amount of time
+ * normalizing a small part of that text.
+ * However, if the entire text is normalized, then the iterator will be
+ * slower than normalizing the entire text at once and iterating over the result.
+ * A possible use of the Normalizer iterator is also to report an index into the
+ * original text that is close to where the normalized characters come from.
+ *
+ * <em>Important:</em> The iterator API was cleaned up significantly for ICU 2.0.
+ * The earlier implementation reported the getIndex() inconsistently,
+ * and previous() could not be used after setIndex(), next(), first(), and current().
+ *
+ * Normalizer allows to start normalizing from anywhere in the input text by
+ * calling setIndexOnly(), first(), or last().
+ * Without calling any of these, the iterator will start at the beginning of the text.
+ *
+ * At any time, next() returns the next normalized code point (UChar32),
+ * with post-increment semantics (like CharacterIterator::next32PostInc()).
+ * previous() returns the previous normalized code point (UChar32),
+ * with pre-decrement semantics (like CharacterIterator::previous32()).
+ *
+ * current() returns the current code point
+ * (respectively the one at the newly set index) without moving
+ * the getIndex(). Note that if the text at the current position
+ * needs to be normalized, then these functions will do that.
+ * (This is why current() is not const.)
+ * It is more efficient to call setIndexOnly() instead, which does not
+ * normalize.
+ *
+ * getIndex() always refers to the position in the input text where the normalized
+ * code points are returned from. It does not always change with each returned
+ * code point.
+ * The code point that is returned from any of the functions
+ * corresponds to text at or after getIndex(), according to the
+ * function's iteration semantics (post-increment or pre-decrement).
+ *
+ * next() returns a code point from at or after the getIndex()
+ * from before the next() call. After the next() call, the getIndex()
+ * might have moved to where the next code point will be returned from
+ * (from a next() or current() call).
+ * This is semantically equivalent to array access with array[index++]
+ * (post-increment semantics).
+ *
+ * previous() returns a code point from at or after the getIndex()
+ * from after the previous() call.
+ * This is semantically equivalent to array access with array[--index]
+ * (pre-decrement semantics).
+ *
+ * Internally, the Normalizer iterator normalizes a small piece of text
+ * starting at the getIndex() and ending at a following "safe" index.
+ * The normalized results is stored in an internal string buffer, and
+ * the code points are iterated from there.
+ * With multiple iteration calls, this is repeated until the next piece
+ * of text needs to be normalized, and the getIndex() needs to be moved.
+ *
+ * The following "safe" index, the internal buffer, and the secondary
+ * iteration index into that buffer are not exposed on the API.
+ * This also means that it is currently not practical to return to
+ * a particular, arbitrary position in the text because one would need to
+ * know, and be able to set, in addition to the getIndex(), at least also the
+ * current index into the internal buffer.
+ * It is currently only possible to observe when getIndex() changes
+ * (with careful consideration of the iteration semantics),
+ * at which time the internal index will be 0.
+ * For example, if getIndex() is different after next() than before it,
+ * then the internal index is 0 and one can return to this getIndex()
+ * later with setIndexOnly().

-/**
- *
- * Abstract base class for all number formats. Provides interface for
- * formatting and parsing a number. Also provides methods for
- * determining which locales have number formats, and what their names
- * are.
- * <P>
- * NumberFormat helps you to format and parse numbers for any locale.
- * Your code can be completely independent of the locale conventions
- * for decimal points, thousands-separators, or even the particular
- * decimal digits used, or whether the number format is even decimal.
- * <P>
- * To format a number for the current Locale, use one of the static
- * factory methods:
- * <pre>
- * \code
- * double myNumber = 7.0;
- * UnicodeString myString;
- * UErrorCode success = U_ZERO_ERROR;
- * NumberFormat* nf = NumberFormat::createInstance(success)
- * nf->format(myNumber, myString);
- * cout << " Example 1: " << myString << endl;
- * \endcode
- * </pre>
- * If you are formatting multiple numbers, it is more efficient to get
- * the format and use it multiple times so that the system doesn't
- * have to fetch the information about the local language and country
- * conventions multiple times.
- * <pre>
- * \code
- * UnicodeString myString;
- * UErrorCode success = U_ZERO_ERROR;
- * nf = NumberFormat::createInstance( success );
- * int32_t a[] = { 123, 3333, -1234567 };
- * const int32_t a_len = sizeof(a) / sizeof(a[0]);
- * myString.remove();
- * for (int32_t i = 0; i < a_len; i++) {
- * nf->format(a[i], myString);
- * myString += " ; ";
- * }
- * cout << " Example 2: " << myString << endl;
- * \endcode
- * </pre>
- * To format a number for a different Locale, specify it in the
- * call to createInstance().
- * <pre>
- * \code
- * nf = NumberFormat::createInstance( Locale::FRENCH, success );
- * \endcode
- * </pre>
- * You can use a NumberFormat to parse also.
- * <pre>
- * \code
- * UErrorCode success;
- * Formattable result(-999); // initialized with error code
- * nf->parse(myString, result, success);
- * \endcode
- * </pre>
- * Use createInstance to get the normal number format for that country.
- * There are other static factory methods available. Use getCurrency
- * to get the currency number format for that country. Use getPercent
- * to get a format for displaying percentages. With this format, a
- * fraction from 0.53 is displayed as 53%.
- * <P>
- * You can also control the display of numbers with such methods as
- * getMinimumFractionDigits. If you want even more control over the
- * format or parsing, or want to give your users more control, you can
- * try casting the NumberFormat you get from the factory methods to a
- * DecimalNumberFormat. This will work for the vast majority of
- * countries; just remember to put it in a try block in case you
- * encounter an unusual one.
- * <P>
- * You can also use forms of the parse and format methods with
- * ParsePosition and FieldPosition to allow you to:
- * <ul type=round>
- * <li>(a) progressively parse through pieces of a string.
- * <li>(b) align the decimal point and other areas.
- * </ul>
- * For example, you can align numbers in two ways.
- * <P>
- * If you are using a monospaced font with spacing for alignment, you
- * can pass the FieldPosition in your format call, with field =
- * INTEGER_FIELD. On output, getEndIndex will be set to the offset
- * between the last character of the integer and the decimal. Add
- * (desiredSpaceCount - getEndIndex) spaces at the front of the
- * string.
- * <P>
- * If you are using proportional fonts, instead of padding with
- * spaces, measure the width of the string in pixels from the start to
- * getEndIndex. Then move the pen by (desiredPixelWidth -
- * widthToAlignmentPoint) before drawing the text. It also works
- * where there is no decimal, but possibly additional characters at
- * the end, e.g. with parentheses in negative numbers: "(12)" for -12.
- * <p>
- * <em>User subclasses are not supported.</em> While clients may write
- * subclasses, such code will not necessarily work and will not be
- * guaranteed to work stably from release to release.

+/**
+ *
+ * Abstract base class for all number formats. Provides interface for
+ * formatting and parsing a number. Also provides methods for
+ * determining which locales have number formats, and what their names
+ * are.
+ * <P>
+ * NumberFormat helps you to format and parse numbers for any locale.
+ * Your code can be completely independent of the locale conventions
+ * for decimal points, thousands-separators, or even the particular
+ * decimal digits used, or whether the number format is even decimal.
+ * <P>
+ * To format a number for the current Locale, use one of the static
+ * factory methods:
+ * <pre>
+ * \code
+ * double myNumber = 7.0;
+ * UnicodeString myString;
+ * UErrorCode success = U_ZERO_ERROR;
+ * NumberFormat* nf = NumberFormat::createInstance(success)
+ * nf->format(myNumber, myString);
+ * cout << " Example 1: " << myString << endl;
+ * \endcode
+ * </pre>
+ * If you are formatting multiple numbers, it is more efficient to get
+ * the format and use it multiple times so that the system doesn't
+ * have to fetch the information about the local language and country
+ * conventions multiple times.
+ * <pre>
+ * \code
+ * UnicodeString myString;
+ * UErrorCode success = U_ZERO_ERROR;
+ * nf = NumberFormat::createInstance( success );
+ * int32_t a[] = { 123, 3333, -1234567 };
+ * const int32_t a_len = sizeof(a) / sizeof(a[0]);
+ * myString.remove();
+ * for (int32_t i = 0; i < a_len; i++) {
+ * nf->format(a[i], myString);
+ * myString += " ; ";
+ * }
+ * cout << " Example 2: " << myString << endl;
+ * \endcode
+ * </pre>
+ * To format a number for a different Locale, specify it in the
+ * call to createInstance().
+ * <pre>
+ * \code
+ * nf = NumberFormat::createInstance( Locale::FRENCH, success );
+ * \endcode
+ * </pre>
+ * You can use a NumberFormat to parse also.
+ * <pre>
+ * \code
+ * UErrorCode success;
+ * Formattable result(-999); // initialized with error code
+ * nf->parse(myString, result, success);
+ * \endcode
+ * </pre>
+ * Use createInstance to get the normal number format for that country.
+ * There are other static factory methods available. Use getCurrency
+ * to get the currency number format for that country. Use getPercent
+ * to get a format for displaying percentages. With this format, a
+ * fraction from 0.53 is displayed as 53%.
+ * <P>
+ * You can also control the display of numbers with such methods as
+ * getMinimumFractionDigits. If you want even more control over the
+ * format or parsing, or want to give your users more control, you can
+ * try casting the NumberFormat you get from the factory methods to a
+ * DecimalNumberFormat. This will work for the vast majority of
+ * countries; just remember to put it in a try block in case you
+ * encounter an unusual one.
+ * <P>
+ * You can also use forms of the parse and format methods with
+ * ParsePosition and FieldPosition to allow you to:
+ * <ul type=round>
+ * <li>(a) progressively parse through pieces of a string.
+ * <li>(b) align the decimal point and other areas.
+ * </ul>
+ * For example, you can align numbers in two ways.
+ * <P>
+ * If you are using a monospaced font with spacing for alignment, you
+ * can pass the FieldPosition in your format call, with field =
+ * INTEGER_FIELD. On output, getEndIndex will be set to the offset
+ * between the last character of the integer and the decimal. Add
+ * (desiredSpaceCount - getEndIndex) spaces at the front of the
+ * string.
+ * <P>
+ * If you are using proportional fonts, instead of padding with
+ * spaces, measure the width of the string in pixels from the start to
+ * getEndIndex. Then move the pen by (desiredPixelWidth -
+ * widthToAlignmentPoint) before drawing the text. It also works
+ * where there is no decimal, but possibly additional characters at
+ * the end, e.g. with parentheses in negative numbers: "(12)" for -12.
+ * <p>
+ * <em>User subclasses are not supported.</em> While clients may write
+ * subclasses, such code will not necessarily work and will not be
+ * guaranteed to work stably from release to release.

-/**
- * <p>
- * <code>PluralFormat</code> supports the creation of internationalized
- * messages with plural inflection. It is based on <i>plural
- * selection</i>, i.e. the caller specifies messages for each
- * plural case that can appear in the users language and the
- * <code>PluralFormat</code> selects the appropriate message based on
- * the number.
- * </p>
- * <h4>The Problem of Plural Forms in Internationalized Messages</h4>
- * <p>
- * Different languages have different ways to inflect
- * plurals. Creating internationalized messages that include plural
- * forms is only feasible when the framework is able to handle plural
- * forms of <i>all</i> languages correctly. <code>ChoiceFormat</code>
- * doesn't handle this well, because it attaches a number interval to
- * each message and selects the message whose interval contains a
- * given number. This can only handle a finite number of
- * intervals. But in some languages, like Polish, one plural case
- * applies to infinitely many intervals (e.g., paucal applies to
- * numbers ending with 2, 3, or 4 except those ending with 12, 13, or
- * 14). Thus <code>ChoiceFormat</code> is not adequate.
- * </p><p>
- * <code>PluralFormat</code> deals with this by breaking the problem
- * into two parts:
- * <ul>
- * <li>It uses <code>PluralRules</code> that can define more complex
- * conditions for a plural case than just a single interval. These plural
- * rules define both what plural cases exist in a language, and to
- * which numbers these cases apply.
- * <li>It provides predefined plural rules for many locales. Thus, the programmer
- * need not worry about the plural cases of a language. On the flip side,
- * the localizer does not have to specify the plural cases; he can simply
- * use the predefined keywords. The whole plural formatting of messages can
- * be done using localized patterns from resource bundles.
- * </ul>
- * </p>
- * <h4>Usage of <code>PluralFormat</code></h4>
- * <p>
- * This discussion assumes that you use <code>PluralFormat</code> with
- * a predefined set of plural rules. You can create one using one of
- * the constructors that takes a <code>locale</code> object. To
- * specify the message pattern, you can either pass it to the
- * constructor or set it explicitly using the
- * <code>applyPattern()</code> method. The <code>format()</code>
- * method takes a number object and selects the message of the
- * matching plural case. This message will be returned.
- * </p>
- * <h5>Patterns and Their Interpretation</h5>
- * <p>
- * The pattern text defines the message output for each plural case of the
- * used locale. The pattern is a sequence of
- * <code><i>caseKeyword</i>{<i>message</i>}</code> clauses, separated by white
- * space characters. Each clause assigns the message <code><i>message</i></code>
- * to the plural case identified by <code><i>caseKeyword</i></code>.
- * </p><p>
- * You always have to define a message text for the default plural case
- * "<code>other</code>" which is contained in every rule set. If the plural
- * rules of the <code>PluralFormat</code> object do not contain a plural case
- * identified by <code><i>caseKeyword</i></code>, U_DEFAULT_KEYWORD_MISSING
- * will be set to status.
- * If you do not specify a message text for a particular plural case, the
- * message text of the plural case "<code>other</code>" gets assigned to this
- * plural case. If you specify more than one message for the same plural case,
- * U_DUPLICATE_KEYWORD will be set to status.
- * <br/>
- * Spaces between <code><i>caseKeyword</i></code> and
- * <code><i>message</i></code> will be ignored; spaces within
- * <code><i>message</i></code> will be preserved.
- * </p><p>
- * The message text for a particular plural case may contain other message
- * format patterns. <code>PluralFormat</code> preserves these so that you
- * can use the strings produced by <code>PluralFormat</code> with other
- * formatters. If you are using <code>PluralFormat</code> inside a
- * <code>MessageFormat</code> pattern, <code>MessageFormat</code> will
- * automatically evaluate the resulting format pattern.<br/>
- * Thus, curly braces (<code>{</code>, <code>}</code>) are <i>only</i> allowed
- * in message texts to define a nested format pattern.<br/>
- * The pound sign (<code>#</code>) will be interpreted as the number placeholder
- * in the message text, if it is not contained in curly braces (to preserve
- * <code>NumberFormat</code> patterns). <code>PluralFormat</code> will
- * replace each of those pound signs by the number passed to the
- * <code>format()</code> method. It will be formatted using a
- * <code>NumberFormat</code> for the <code>PluralFormat</code>'s locale. If you
- * need special number formatting, you have to explicitly specify a
- * <code>NumberFormat</code> for the <code>PluralFormat</code> to use.
- * </p>
- * Example
- * <pre>
- * UErrorCode status = U_ZERO_ERROR;
- * MessageFormat* msgFmt = new MessageFormat(UnicodeString("{0, plural,
- * one{{0, number, C''est #,##0.0# fichier}} other {Ce sont # fichiers}} dans la liste."),
- * Locale("fr"), status);
- * if (U_FAILURE(status)) {
- * return;
- * }
- * Formattable args1[] = {(int32_t)0};
- * Formattable args2[] = {(int32_t)3};
- * FieldPosition ignore(FieldPosition::DONT_CARE);
- * UnicodeString result;
- * msgFmt->format(args1, 1, result, ignore, status);
- * cout << result << endl;
- * result.remove();
- * msgFmt->format(args2, 1, result, ignore, status);
- * cout << result << endl;
- * </pre>
- * Produces the output:<br/>
- * <code>C'est 0,0 fichier dans la liste.</code><br/>
- * <code>Ce sont 3 fichiers dans la liste."</code>
- * <p>
- * <strong>Note:</strong><br/>
- * Currently <code>PluralFormat</code>
- * does not make use of quotes like <code>MessageFormat</code>.
- * If you use plural format strings with <code>MessageFormat</code> and want
- * to use a quote sign "<code>'</code>", you have to write "<code>''</code>".
- * <code>MessageFormat</code> unquotes this pattern and passes the unquoted
- * pattern to <code>PluralFormat</code>. It's a bit trickier if you use
- * nested formats that do quoting. In the example above, we wanted to insert
- * "<code>'</code>" in the number format pattern. Since
- * <code>NumberFormat</code> supports quotes, we had to insert
- * "<code>''</code>". But since <code>MessageFormat</code> unquotes the
- * pattern before it gets passed to <code>PluralFormat</code>, we have to
- * double these quotes, i.e. write "<code>''''</code>".
- * </p>
- * <h4>Defining Custom Plural Rules</h4>
- * <p>If you need to use <code>PluralFormat</code> with custom rules, you can
- * create a <code>PluralRules</code> object and pass it to
- * <code>PluralFormat</code>'s constructor. If you also specify a locale in this
- * constructor, this locale will be used to format the number in the message
- * texts.
- * </p><p>
- * For more information about <code>PluralRules</code>, see
- * {@link PluralRules}.

+/**
+ * <p>
+ * <code>PluralFormat</code> supports the creation of internationalized
+ * messages with plural inflection. It is based on <i>plural
+ * selection</i>, i.e. the caller specifies messages for each
+ * plural case that can appear in the users language and the
+ * <code>PluralFormat</code> selects the appropriate message based on
+ * the number.
+ * </p>
+ * <h4>The Problem of Plural Forms in Internationalized Messages</h4>
+ * <p>
+ * Different languages have different ways to inflect
+ * plurals. Creating internationalized messages that include plural
+ * forms is only feasible when the framework is able to handle plural
+ * forms of <i>all</i> languages correctly. <code>ChoiceFormat</code>
+ * doesn't handle this well, because it attaches a number interval to
+ * each message and selects the message whose interval contains a
+ * given number. This can only handle a finite number of
+ * intervals. But in some languages, like Polish, one plural case
+ * applies to infinitely many intervals (e.g., paucal applies to
+ * numbers ending with 2, 3, or 4 except those ending with 12, 13, or
+ * 14). Thus <code>ChoiceFormat</code> is not adequate.
+ * </p><p>
+ * <code>PluralFormat</code> deals with this by breaking the problem
+ * into two parts:
+ * <ul>
+ * <li>It uses <code>PluralRules</code> that can define more complex
+ * conditions for a plural case than just a single interval. These plural
+ * rules define both what plural cases exist in a language, and to
+ * which numbers these cases apply.
+ * <li>It provides predefined plural rules for many locales. Thus, the programmer
+ * need not worry about the plural cases of a language. On the flip side,
+ * the localizer does not have to specify the plural cases; he can simply
+ * use the predefined keywords. The whole plural formatting of messages can
+ * be done using localized patterns from resource bundles.
+ * </ul>
+ * </p>
+ * <h4>Usage of <code>PluralFormat</code></h4>
+ * <p>
+ * This discussion assumes that you use <code>PluralFormat</code> with
+ * a predefined set of plural rules. You can create one using one of
+ * the constructors that takes a <code>locale</code> object. To
+ * specify the message pattern, you can either pass it to the
+ * constructor or set it explicitly using the
+ * <code>applyPattern()</code> method. The <code>format()</code>
+ * method takes a number object and selects the message of the
+ * matching plural case. This message will be returned.
+ * </p>
+ * <h5>Patterns and Their Interpretation</h5>
+ * <p>
+ * The pattern text defines the message output for each plural case of the
+ * used locale. The pattern is a sequence of
+ * <code><i>caseKeyword</i>{<i>message</i>}</code> clauses, separated by white
+ * space characters. Each clause assigns the message <code><i>message</i></code>
+ * to the plural case identified by <code><i>caseKeyword</i></code>.
+ * </p><p>
+ * You always have to define a message text for the default plural case
+ * "<code>other</code>" which is contained in every rule set. If the plural
+ * rules of the <code>PluralFormat</code> object do not contain a plural case
+ * identified by <code><i>caseKeyword</i></code>, U_DEFAULT_KEYWORD_MISSING
+ * will be set to status.
+ * If you do not specify a message text for a particular plural case, the
+ * message text of the plural case "<code>other</code>" gets assigned to this
+ * plural case. If you specify more than one message for the same plural case,
+ * U_DUPLICATE_KEYWORD will be set to status.
+ * <br/>
+ * Spaces between <code><i>caseKeyword</i></code> and
+ * <code><i>message</i></code> will be ignored; spaces within
+ * <code><i>message</i></code> will be preserved.
+ * </p><p>
+ * The message text for a particular plural case may contain other message
+ * format patterns. <code>PluralFormat</code> preserves these so that you
+ * can use the strings produced by <code>PluralFormat</code> with other
+ * formatters. If you are using <code>PluralFormat</code> inside a
+ * <code>MessageFormat</code> pattern, <code>MessageFormat</code> will
+ * automatically evaluate the resulting format pattern.<br/>
+ * Thus, curly braces (<code>{</code>, <code>}</code>) are <i>only</i> allowed
+ * in message texts to define a nested format pattern.<br/>
+ * The pound sign (<code>#</code>) will be interpreted as the number placeholder
+ * in the message text, if it is not contained in curly braces (to preserve
+ * <code>NumberFormat</code> patterns). <code>PluralFormat</code> will
+ * replace each of those pound signs by the number passed to the
+ * <code>format()</code> method. It will be formatted using a
+ * <code>NumberFormat</code> for the <code>PluralFormat</code>'s locale. If you
+ * need special number formatting, you have to explicitly specify a
+ * <code>NumberFormat</code> for the <code>PluralFormat</code> to use.
+ * </p>
+ * Example
+ * <pre>
+ * UErrorCode status = U_ZERO_ERROR;
+ * MessageFormat* msgFmt = new MessageFormat(UnicodeString("{0, plural,
+ * one{{0, number, C''est #,##0.0# fichier}} other {Ce sont # fichiers}} dans la liste."),
+ * Locale("fr"), status);
+ * if (U_FAILURE(status)) {
+ * return;
+ * }
+ * Formattable args1[] = {(int32_t)0};
+ * Formattable args2[] = {(int32_t)3};
+ * FieldPosition ignore(FieldPosition::DONT_CARE);
+ * UnicodeString result;
+ * msgFmt->format(args1, 1, result, ignore, status);
+ * cout << result << endl;
+ * result.remove();
+ * msgFmt->format(args2, 1, result, ignore, status);
+ * cout << result << endl;
+ * </pre>
+ * Produces the output:<br/>
+ * <code>C'est 0,0 fichier dans la liste.</code><br/>
+ * <code>Ce sont 3 fichiers dans la liste."</code>
+ * <p>
+ * <strong>Note:</strong><br/>
+ * Currently <code>PluralFormat</code>
+ * does not make use of quotes like <code>MessageFormat</code>.
+ * If you use plural format strings with <code>MessageFormat</code> and want
+ * to use a quote sign "<code>'</code>", you have to write "<code>''</code>".
+ * <code>MessageFormat</code> unquotes this pattern and passes the unquoted
+ * pattern to <code>PluralFormat</code>. It's a bit trickier if you use
+ * nested formats that do quoting. In the example above, we wanted to insert
+ * "<code>'</code>" in the number format pattern. Since
+ * <code>NumberFormat</code> supports quotes, we had to insert
+ * "<code>''</code>". But since <code>MessageFormat</code> unquotes the
+ * pattern before it gets passed to <code>PluralFormat</code>, we have to
+ * double these quotes, i.e. write "<code>''''</code>".
+ * </p>
+ * <h4>Defining Custom Plural Rules</h4>
+ * <p>If you need to use <code>PluralFormat</code> with custom rules, you can
+ * create a <code>PluralRules</code> object and pass it to
+ * <code>PluralFormat</code>'s constructor. If you also specify a locale in this
+ * constructor, this locale will be used to format the number in the message
+ * texts.
+ * </p><p>
+ * For more information about <code>PluralRules</code>, see
+ * {@link PluralRules}.

- * keywords. Rules are constructed from a text description, consisting
- * of a series of keywords and conditions. The {@link #select} method
- * examines each condition in order and returns the keyword for the
- * first condition that matches the number. If none match,
- * default rule(other) is returned.
- *
- * Examples:<pre>
- * "one: n is 1; few: n in 2..4"</pre>
- * This defines two rules, for 'one' and 'few'. The condition for
- * 'one' is "n is 1" which means that the number must be equal to
- * 1 for this condition to pass. The condition for 'few' is
- * "n in 2..4" which means that the number must be between 2 and
- * 4 inclusive for this condition to pass. All other numbers
- * are assigned the keyword "other" by the default rule.
- * </p><pre>
- * "zero: n is 0; one: n is 1; zero: n mod 100 in 1..19"</pre>
- * This illustrates that the same keyword can be defined multiple times.
- * Each rule is examined in order, and the first keyword whose condition
- * passes is the one returned. Also notes that a modulus is applied
- * to n in the last rule. Thus its condition holds for 119, 219, 319...
- * </p><pre>
- * "one: n is 1; few: n mod 10 in 2..4 and n mod 100 not in 12..14"</pre>
- * This illustrates conjunction and negation. The condition for 'few'
- * has two parts, both of which must be met: "n mod 10 in 2..4" and
- * "n mod 100 not in 12..14". The first part applies a modulus to n
- * before the test as in the previous example. The second part applies
- * a different modulus and also uses negation, thus it matches all
- * numbers _not_ in 12, 13, 14, 112, 113, 114, 212, 213, 214...
- * </p>
- * <p>
- * Syntax:<pre>
- * rules = rule (';' rule)*
- * rule = keyword ':' condition
- * keyword = <identifier>
- * condition = and_condition ('or' and_condition)*
- * and_condition = relation ('and' relation)*
- * relation = is_relation | in_relation | within_relation | 'n' <EOL>
- * is_relation = expr 'is' ('not')? value
- * in_relation = expr ('not')? 'in' range
- * within_relation = expr ('not')? 'within' range
- * expr = 'n' ('mod' value)?
- * value = digit+
- * digit = 0|1|2|3|4|5|6|7|8|9
- * range = value'..'value
- * </pre></p>
- * <p>
- * The difference between 'in' and 'within' is that 'in' only includes
- * integers in the specified range, while 'within' includes all values.</p>
- * <p>
- * Keywords
- * could be defined by users or from ICU locale data. There are 6
- * predefined values in ICU - 'zero', 'one', 'two', 'few', 'many' and
- * 'other'. Callers need to check the value of keyword returned by
- * {@link #select} method.
- * </p>
- *
- * Examples:<pre>
- * UnicodeString keyword = pl->select(number);
- * if (keyword== UnicodeString("one") {
- * ...
- * }
- * else if ( ... )
- * </pre>

-/**
- * The RuleBasedNumberFormat class formats numbers according to a set of rules. This number formatter is
- * typically used for spelling out numeric values in words (e.g., 25,3476 as
- * "twenty-five thousand three hundred seventy-six" or "vingt-cinq mille trois
- * cents soixante-seize" or
- * "fünfundzwanzigtausenddreihundertsechsundsiebzig"), but can also be used for
- * other complicated formatting tasks, such as formatting a number of seconds as hours,
- * minutes and seconds (e.g., 3,730 as "1:02:10").
- *
- * <p>The resources contain three predefined formatters for each locale: spellout, which
- * spells out a value in words (123 is "one hundred twenty-three"); ordinal, which
- * appends an ordinal suffix to the end of a numeral (123 is "123rd"); and
- * duration, which shows a duration in seconds as hours, minutes, and seconds (123 is
- * "2:03"). The client can also define more specialized <tt>RuleBasedNumberFormat</tt>s
- * by supplying programmer-defined rule sets.</p>
- *
- * <p>The behavior of a <tt>RuleBasedNumberFormat</tt> is specified by a textual description
- * that is either passed to the constructor as a <tt>String</tt> or loaded from a resource
- * bundle. In its simplest form, the description consists of a semicolon-delimited list of <em>rules.</em>
- * Each rule has a string of output text and a value or range of values it is applicable to.
- * In a typical spellout rule set, the first twenty rules are the words for the numbers from
- * 0 to 19:</p>
- *
- * <pre>zero; one; two; three; four; five; six; seven; eight; nine;
- * ten; eleven; twelve; thirteen; fourteen; fifteen; sixteen; seventeen; eighteen; nineteen;</pre>
- *
- * <p>For larger numbers, we can use the preceding set of rules to format the ones place, and
- * we only have to supply the words for the multiples of 10:</p>
- *
- * <pre> 20: twenty[->>];
- * 30: thirty[->>];
- * 40: forty[->>];
- * 50: fifty[->>];
- * 60: sixty[->>];
- * 70: seventy[->>];
- * 80: eighty[->>];
- * 90: ninety[->>];</pre>
- *
- * <p>In these rules, the <em>base value</em> is spelled out explicitly and set off from the
- * rule's output text with a colon. The rules are in a sorted list, and a rule is applicable
- * to all numbers from its own base value to one less than the next rule's base value. The
- * ">>" token is called a <em>substitution</em> and tells the fomatter to
- * isolate the number's ones digit, format it using this same set of rules, and place the
- * result at the position of the ">>" token. Text in brackets is omitted if
- * the number being formatted is an even multiple of 10 (the hyphen is a literal hyphen; 24
- * is "twenty-four," not "twenty four").</p>
- *
- * <p>For even larger numbers, we can actually look up several parts of the number in the
- * list:</p>
- *
- * <pre>100: << hundred[ >>];</pre>
- *
- * <p>The "<<" represents a new kind of substitution. The << isolates
- * the hundreds digit (and any digits to its left), formats it using this same rule set, and
- * places the result where the "<<" was. Notice also that the meaning of
- * >> has changed: it now refers to both the tens and the ones digits. The meaning of
- * both substitutions depends on the rule's base value. The base value determines the rule's <em>divisor,</em>
- * which is the highest power of 10 that is less than or equal to the base value (the user
- * can change this). To fill in the substitutions, the formatter divides the number being
- * formatted by the divisor. The integral quotient is used to fill in the <<
- * substitution, and the remainder is used to fill in the >> substitution. The meaning
- * of the brackets changes similarly: text in brackets is omitted if the value being
- * formatted is an even multiple of the rule's divisor. The rules are applied recursively, so
- * if a substitution is filled in with text that includes another substitution, that
- * substitution is also filled in.</p>
- *
- * <p>This rule covers values up to 999, at which point we add another rule:</p>
- *
- * <pre>1000: << thousand[ >>];</pre>
- *
- * <p>Again, the meanings of the brackets and substitution tokens shift because the rule's
- * base value is a higher power of 10, changing the rule's divisor. This rule can actually be
- * used all the way up to 999,999. This allows us to finish out the rules as follows:</p>
- *
- * <pre> 1,000,000: << million[ >>];
- * 1,000,000,000: << billion[ >>];
- * 1,000,000,000,000: << trillion[ >>];
- * 1,000,000,000,000,000: OUT OF RANGE!;</pre>
- *
- * <p>Commas, periods, and spaces can be used in the base values to improve legibility and
- * are ignored by the rule parser. The last rule in the list is customarily treated as an
- * "overflow rule," applying to everything from its base value on up, and often (as
- * in this example) being used to print out an error message or default representation.
- * Notice also that the size of the major groupings in large numbers is controlled by the
- * spacing of the rules: because in English we group numbers by thousand, the higher rules
- * are separated from each other by a factor of 1,000.</p>
- *
- * <p>To see how these rules actually work in practice, consider the following example:
- * Formatting 25,430 with this rule set would work like this:</p>
- *
- * <table border="0" width="100%">
- * <tr>
- * <td><strong><< thousand >></strong></td>
- * <td>[the rule whose base value is 1,000 is applicable to 25,340]</td>
- * </tr>
- * <tr>
- * <td><strong>twenty->></strong> thousand >></td>
- * <td>[25,340 over 1,000 is 25. The rule for 20 applies.]</td>
- * </tr>
- * <tr>
- * <td>twenty-<strong>five</strong> thousand >></td>
- * <td>[25 mod 10 is 5. The rule for 5 is "five."</td>
- * </tr>
- * <tr>
- * <td>twenty-five thousand <strong><< hundred >></strong></td>
- * <td>[25,340 mod 1,000 is 340. The rule for 100 applies.]</td>
- * </tr>
- * <tr>
- * <td>twenty-five thousand <strong>three</strong> hundred >></td>
- * <td>[340 over 100 is 3. The rule for 3 is "three."]</td>
- * </tr>
- * <tr>
- * <td>twenty-five thousand three hundred <strong>forty</strong></td>
- * <td>[340 mod 100 is 40. The rule for 40 applies. Since 40 divides
- * evenly by 10, the hyphen and substitution in the brackets are omitted.]</td>
- * </tr>
- * </table>
- *
- * <p>The above syntax suffices only to format positive integers. To format negative numbers,
- * we add a special rule:</p>
- *
- * <pre>-x: minus >>;</pre>
- *
- * <p>This is called a <em>negative-number rule,</em> and is identified by "-x"
- * where the base value would be. This rule is used to format all negative numbers. the
- * >> token here means "find the number's absolute value, format it with these
- * rules, and put the result here."</p>
- *
- * <p>We also add a special rule called a <em>fraction rule </em>for numbers with fractional
- * parts:</p>
- *
- * <pre>x.x: << point >>;</pre>
- *
- * <p>This rule is used for all positive non-integers (negative non-integers pass through the
- * negative-number rule first and then through this rule). Here, the << token refers to
- * the number's integral part, and the >> to the number's fractional part. The
- * fractional part is formatted as a series of single-digit numbers (e.g., 123.456 would be
- * formatted as "one hundred twenty-three point four five six").</p>
- *
- * <p>To see how this rule syntax is applied to various languages, examine the resource data.</p>
- *
- * <p>There is actually much more flexibility built into the rule language than the
- * description above shows. A formatter may own multiple rule sets, which can be selected by
- * the caller, and which can use each other to fill in their substitutions. Substitutions can
- * also be filled in with digits, using a DecimalFormat object. There is syntax that can be
- * used to alter a rule's divisor in various ways. And there is provision for much more
- * flexible fraction handling. A complete description of the rule syntax follows:</p>
- *
- * <hr>
- *
- * <p>The description of a <tt>RuleBasedNumberFormat</tt>'s behavior consists of one or more <em>rule
- * sets.</em> Each rule set consists of a name, a colon, and a list of <em>rules.</em> A rule
- * set name must begin with a % sign. Rule sets with names that begin with a single % sign
- * are <em>public:</em> the caller can specify that they be used to format and parse numbers.
- * Rule sets with names that begin with %% are <em>private:</em> they exist only for the use
- * of other rule sets. If a formatter only has one rule set, the name may be omitted.</p>
- *
- * <p>The user can also specify a special "rule set" named <tt>%%lenient-parse</tt>.
- * The body of <tt>%%lenient-parse</tt> isn't a set of number-formatting rules, but a <tt>RuleBasedCollator</tt>
- * description which is used to define equivalences for lenient parsing. For more information
- * on the syntax, see <tt>RuleBasedCollator</tt>. For more information on lenient parsing,
- * see <tt>setLenientParse()</tt>. <em>Note:</em> symbols that have syntactic meaning
- * in collation rules, such as '&', have no particular meaning when appearing outside
- * of the <tt>lenient-parse</tt> rule set.</p>
- *
- * <p>The body of a rule set consists of an ordered, semicolon-delimited list of <em>rules.</em>
- * Internally, every rule has a base value, a divisor, rule text, and zero, one, or two <em>substitutions.</em>
- * These parameters are controlled by the description syntax, which consists of a <em>rule
- * descriptor,</em> a colon, and a <em>rule body.</em></p>
- *
- * <p>A rule descriptor can take one of the following forms (text in <em>italics</em> is the
- * name of a token):</p>
- *
- * <table border="0" width="100%">
- * <tr>
- * <td><em>bv</em>:</td>
- * <td><em>bv</em> specifies the rule's base value. <em>bv</em> is a decimal
- * number expressed using ASCII digits. <em>bv</em> may contain spaces, period, and commas,
- * which are ignored. The rule's divisor is the highest power of 10 less than or equal to
- * the base value.</td>
- * </tr>
- * <tr>
- * <td><em>bv</em>/<em>rad</em>:</td>
- * <td><em>bv</em> specifies the rule's base value. The rule's divisor is the
- * highest power of <em>rad</em> less than or equal to the base value.</td>
- * </tr>
- * <tr>
- * <td><em>bv</em>>:</td>
- * <td><em>bv</em> specifies the rule's base value. To calculate the divisor,
- * let the radix be 10, and the exponent be the highest exponent of the radix that yields a
- * result less than or equal to the base value. Every > character after the base value
- * decreases the exponent by 1. If the exponent is positive or 0, the divisor is the radix
- * raised to the power of the exponent; otherwise, the divisor is 1.</td>

- * </table>
- *
- * <p>A rule set may be either a regular rule set or a <em>fraction rule set,</em> depending
- * on whether it is used to format a number's integral part (or the whole number) or a
- * number's fractional part. Using a rule set to format a rule's fractional part makes it a
- * fraction rule set.</p>
- *
- * <p>Which rule is used to format a number is defined according to one of the following
- * algorithms: If the rule set is a regular rule set, do the following:
- *
- * <ul>
- * <li>If the rule set includes a master rule (and the number was passed in as a <tt>double</tt>),
- * use the master rule. (If the number being formatted was passed in as a <tt>long</tt>,
- * the master rule is ignored.)</li>
- * <li>If the number is negative, use the negative-number rule.</li>
- * <li>If the number has a fractional part and is greater than 1, use the improper fraction
- * rule.</li>
- * <li>If the number has a fractional part and is between 0 and 1, use the proper fraction
- * rule.</li>
- * <li>Binary-search the rule list for the rule with the highest base value less than or equal
- * to the number. If that rule has two substitutions, its base value is not an even multiple
- * of its divisor, and the number <em>is</em> an even multiple of the rule's divisor, use the
- * rule that precedes it in the rule list. Otherwise, use the rule itself.</li>
- * </ul>
- *
- * <p>If the rule set is a fraction rule set, do the following:
- *
- * <ul>
- * <li>Ignore negative-number and fraction rules.</li>
- * <li>For each rule in the list, multiply the number being formatted (which will always be
- * between 0 and 1) by the rule's base value. Keep track of the distance between the result
- * the nearest integer.</li>
- * <li>Use the rule that produced the result closest to zero in the above calculation. In the
- * event of a tie or a direct hit, use the first matching rule encountered. (The idea here is
- * to try each rule's base value as a possible denominator of a fraction. Whichever
- * denominator produces the fraction closest in value to the number being formatted wins.) If
- * the rule following the matching rule has the same base value, use it if the numerator of
- * the fraction is anything other than 1; if the numerator is 1, use the original matching
- * rule. (This is to allow singular and plural forms of the rule text without a lot of extra
- * hassle.)</li>
- * </ul>
- *
- * <p>A rule's body consists of a string of characters terminated by a semicolon. The rule
- * may include zero, one, or two <em>substitution tokens,</em> and a range of text in
- * brackets. The brackets denote optional text (and may also include one or both
- * substitutions). The exact meanings of the substitution tokens, and under what conditions
- * optional text is omitted, depend on the syntax of the substitution token and the context.
- * The rest of the text in a rule body is literal text that is output when the rule matches
- * the number being formatted.</p>
- *
- * <p>A substitution token begins and ends with a <em>token character.</em> The token
- * character and the context together specify a mathematical operation to be performed on the
- * number being formatted. An optional <em>substitution descriptor </em>specifies how the
- * value resulting from that operation is used to fill in the substitution. The position of
- * the substitution token in the rule body specifies the location of the resultant text in
- * the original rule text.</p>
- *
- * <p>The meanings of the substitution token characters are as follows:</p>
- *
- * <table border="0" width="100%">
- * <tr>
- * <td>>></td>
- * <td>in normal rule</td>

- * <li>If you omit the substitution descriptor in a << substitution in a rule in a
- * fraction rule set, format the result using the default rule set for this formatter.</li>
- * </ul>
- * </td>
- * </tr>
- * </table>
- *
- * <p>Whitespace is ignored between a rule set name and a rule set body, between a rule
- * descriptor and a rule body, or between rules. If a rule body begins with an apostrophe,
- * the apostrophe is ignored, but all text after it becomes significant (this is how you can
- * have a rule's rule text begin with whitespace). There is no escape function: the semicolon
- * is not allowed in rule set names or in rule text, and the colon is not allowed in rule set
- * names. The characters beginning a substitution token are always treated as the beginning
- * of a substitution token.</p>
- *
- * <p>See the resource data and the demo program for annotated examples of real rule sets

- *
- * <p><em>User subclasses are not supported.</em> While clients may write
- * subclasses, such code will not necessarily work and will not be
- * guaranteed to work stably from release to release.
- *
- * <p><b>Localizations</b></p>
- * <p>Constructors are available that allow the specification of localizations for the
- * public rule sets (and also allow more control over what public rule sets are available).
- * Localization data is represented as a textual description. The description represents
- * an array of arrays of string. The first element is an array of the public rule set names,
- * each of these must be one of the public rule set names that appear in the rules. Only
- * names in this array will be treated as public rule set names by the API. Each subsequent
- * element is an array of localizations of these names. The first element of one of these
- * subarrays is the locale name, and the remaining elements are localizations of the
- * public rule set names, in the same order as they were listed in the first arrray.</p>
- * <p>In the syntax, angle brackets '<', '>' are used to delimit the arrays, and comma ',' is used
- * to separate elements of an array. Whitespace is ignored, unless quoted.</p>
- * <p>For example:<pre>
- * < < %foo, %bar, %baz >,
- * < en, Foo, Bar, Baz >,
- * < fr, 'le Foo', 'le Bar', 'le Baz' >
- * < zh, \\u7532, \\u4e59, \\u4e19 > >

+/**
+ * The RuleBasedNumberFormat class formats numbers according to a set of rules. This number formatter is
+ * typically used for spelling out numeric values in words (e.g., 25,3476 as
+ * "twenty-five thousand three hundred seventy-six" or "vingt-cinq mille trois
+ * cents soixante-seize" or
+ * "fünfundzwanzigtausenddreihundertsechsundsiebzig"), but can also be used for
+ * other complicated formatting tasks, such as formatting a number of seconds as hours,
+ * minutes and seconds (e.g., 3,730 as "1:02:10").
+ *
+ * <p>The resources contain three predefined formatters for each locale: spellout, which
+ * spells out a value in words (123 is "one hundred twenty-three"); ordinal, which
+ * appends an ordinal suffix to the end of a numeral (123 is "123rd"); and
+ * duration, which shows a duration in seconds as hours, minutes, and seconds (123 is
+ * "2:03"). The client can also define more specialized <tt>RuleBasedNumberFormat</tt>s
+ * by supplying programmer-defined rule sets.</p>
+ *
+ * <p>The behavior of a <tt>RuleBasedNumberFormat</tt> is specified by a textual description
+ * that is either passed to the constructor as a <tt>String</tt> or loaded from a resource
+ * bundle. In its simplest form, the description consists of a semicolon-delimited list of <em>rules.</em>
+ * Each rule has a string of output text and a value or range of values it is applicable to.
+ * In a typical spellout rule set, the first twenty rules are the words for the numbers from
+ * 0 to 19:</p>
+ *
+ * <pre>zero; one; two; three; four; five; six; seven; eight; nine;
+ * ten; eleven; twelve; thirteen; fourteen; fifteen; sixteen; seventeen; eighteen; nineteen;</pre>
+ *
+ * <p>For larger numbers, we can use the preceding set of rules to format the ones place, and
+ * we only have to supply the words for the multiples of 10:</p>
+ *
+ * <pre> 20: twenty[->>];
+ * 30: thirty[->>];
+ * 40: forty[->>];
+ * 50: fifty[->>];
+ * 60: sixty[->>];
+ * 70: seventy[->>];
+ * 80: eighty[->>];
+ * 90: ninety[->>];</pre>
+ *
+ * <p>In these rules, the <em>base value</em> is spelled out explicitly and set off from the
+ * rule's output text with a colon. The rules are in a sorted list, and a rule is applicable
+ * to all numbers from its own base value to one less than the next rule's base value. The
+ * ">>" token is called a <em>substitution</em> and tells the fomatter to
+ * isolate the number's ones digit, format it using this same set of rules, and place the
+ * result at the position of the ">>" token. Text in brackets is omitted if
+ * the number being formatted is an even multiple of 10 (the hyphen is a literal hyphen; 24
+ * is "twenty-four," not "twenty four").</p>
+ *
+ * <p>For even larger numbers, we can actually look up several parts of the number in the
+ * list:</p>
+ *
+ * <pre>100: << hundred[ >>];</pre>
+ *
+ * <p>The "<<" represents a new kind of substitution. The << isolates
+ * the hundreds digit (and any digits to its left), formats it using this same rule set, and
+ * places the result where the "<<" was. Notice also that the meaning of
+ * >> has changed: it now refers to both the tens and the ones digits. The meaning of
+ * both substitutions depends on the rule's base value. The base value determines the rule's <em>divisor,</em>
+ * which is the highest power of 10 that is less than or equal to the base value (the user
+ * can change this). To fill in the substitutions, the formatter divides the number being
+ * formatted by the divisor. The integral quotient is used to fill in the <<
+ * substitution, and the remainder is used to fill in the >> substitution. The meaning
+ * of the brackets changes similarly: text in brackets is omitted if the value being
+ * formatted is an even multiple of the rule's divisor. The rules are applied recursively, so
+ * if a substitution is filled in with text that includes another substitution, that
+ * substitution is also filled in.</p>
+ *
+ * <p>This rule covers values up to 999, at which point we add another rule:</p>
+ *
+ * <pre>1000: << thousand[ >>];</pre>
+ *
+ * <p>Again, the meanings of the brackets and substitution tokens shift because the rule's
+ * base value is a higher power of 10, changing the rule's divisor. This rule can actually be
+ * used all the way up to 999,999. This allows us to finish out the rules as follows:</p>
+ *
+ * <pre> 1,000,000: << million[ >>];
+ * 1,000,000,000: << billion[ >>];
+ * 1,000,000,000,000: << trillion[ >>];
+ * 1,000,000,000,000,000: OUT OF RANGE!;</pre>
+ *
+ * <p>Commas, periods, and spaces can be used in the base values to improve legibility and
+ * are ignored by the rule parser. The last rule in the list is customarily treated as an
+ * "overflow rule," applying to everything from its base value on up, and often (as
+ * in this example) being used to print out an error message or default representation.
+ * Notice also that the size of the major groupings in large numbers is controlled by the
+ * spacing of the rules: because in English we group numbers by thousand, the higher rules
+ * are separated from each other by a factor of 1,000.</p>
+ *
+ * <p>To see how these rules actually work in practice, consider the following example:
+ * Formatting 25,430 with this rule set would work like this:</p>
+ *
+ * <table border="0" width="100%">
+ * <tr>
+ * <td><strong><< thousand >></strong></td>
+ * <td>[the rule whose base value is 1,000 is applicable to 25,340]</td>
+ * </tr>
+ * <tr>
+ * <td><strong>twenty->></strong> thousand >></td>
+ * <td>[25,340 over 1,000 is 25. The rule for 20 applies.]</td>
+ * </tr>
+ * <tr>
+ * <td>twenty-<strong>five</strong> thousand >></td>
+ * <td>[25 mod 10 is 5. The rule for 5 is "five."</td>
+ * </tr>
+ * <tr>
+ * <td>twenty-five thousand <strong><< hundred >></strong></td>
+ * <td>[25,340 mod 1,000 is 340. The rule for 100 applies.]</td>
+ * </tr>
+ * <tr>
+ * <td>twenty-five thousand <strong>three</strong> hundred >></td>
+ * <td>[340 over 100 is 3. The rule for 3 is "three."]</td>
+ * </tr>
+ * <tr>
+ * <td>twenty-five thousand three hundred <strong>forty</strong></td>
+ * <td>[340 mod 100 is 40. The rule for 40 applies. Since 40 divides
+ * evenly by 10, the hyphen and substitution in the brackets are omitted.]</td>
+ * </tr>
+ * </table>
+ *
+ * <p>The above syntax suffices only to format positive integers. To format negative numbers,
+ * we add a special rule:</p>
+ *
+ * <pre>-x: minus >>;</pre>
+ *
+ * <p>This is called a <em>negative-number rule,</em> and is identified by "-x"
+ * where the base value would be. This rule is used to format all negative numbers. the
+ * >> token here means "find the number's absolute value, format it with these
+ * rules, and put the result here."</p>
+ *
+ * <p>We also add a special rule called a <em>fraction rule </em>for numbers with fractional
+ * parts:</p>
+ *
+ * <pre>x.x: << point >>;</pre>
+ *
+ * <p>This rule is used for all positive non-integers (negative non-integers pass through the
+ * negative-number rule first and then through this rule). Here, the << token refers to
+ * the number's integral part, and the >> to the number's fractional part. The
+ * fractional part is formatted as a series of single-digit numbers (e.g., 123.456 would be
+ * formatted as "one hundred twenty-three point four five six").</p>
+ *
+ * <p>To see how this rule syntax is applied to various languages, examine the resource data.</p>
+ *
+ * <p>There is actually much more flexibility built into the rule language than the
+ * description above shows. A formatter may own multiple rule sets, which can be selected by
+ * the caller, and which can use each other to fill in their substitutions. Substitutions can
+ * also be filled in with digits, using a DecimalFormat object. There is syntax that can be
+ * used to alter a rule's divisor in various ways. And there is provision for much more
+ * flexible fraction handling. A complete description of the rule syntax follows:</p>
+ *
+ * <hr>
+ *
+ * <p>The description of a <tt>RuleBasedNumberFormat</tt>'s behavior consists of one or more <em>rule
+ * sets.</em> Each rule set consists of a name, a colon, and a list of <em>rules.</em> A rule
+ * set name must begin with a % sign. Rule sets with names that begin with a single % sign
+ * are <em>public:</em> the caller can specify that they be used to format and parse numbers.
+ * Rule sets with names that begin with %% are <em>private:</em> they exist only for the use
+ * of other rule sets. If a formatter only has one rule set, the name may be omitted.</p>
+ *
+ * <p>The user can also specify a special "rule set" named <tt>%%lenient-parse</tt>.
+ * The body of <tt>%%lenient-parse</tt> isn't a set of number-formatting rules, but a <tt>RuleBasedCollator</tt>
+ * description which is used to define equivalences for lenient parsing. For more information
+ * on the syntax, see <tt>RuleBasedCollator</tt>. For more information on lenient parsing,
+ * see <tt>setLenientParse()</tt>. <em>Note:</em> symbols that have syntactic meaning
+ * in collation rules, such as '&', have no particular meaning when appearing outside
+ * of the <tt>lenient-parse</tt> rule set.</p>
+ *
+ * <p>The body of a rule set consists of an ordered, semicolon-delimited list of <em>rules.</em>
+ * Internally, every rule has a base value, a divisor, rule text, and zero, one, or two <em>substitutions.</em>
+ * These parameters are controlled by the description syntax, which consists of a <em>rule
+ * descriptor,</em> a colon, and a <em>rule body.</em></p>
+ *
+ * <p>A rule descriptor can take one of the following forms (text in <em>italics</em> is the
+ * name of a token):</p>
+ *
+ * <table border="0" width="100%">
+ * <tr>
+ * <td><em>bv</em>:</td>
+ * <td><em>bv</em> specifies the rule's base value. <em>bv</em> is a decimal

+ * the base value.</td>
+ * </tr>
+ * <tr>

+ *
+ * <p>A rule set may be either a regular rule set or a <em>fraction rule set,</em> depending
+ * on whether it is used to format a number's integral part (or the whole number) or a
+ * number's fractional part. Using a rule set to format a rule's fractional part makes it a
+ * fraction rule set.</p>
+ *
+ * <p>Which rule is used to format a number is defined according to one of the following
+ * algorithms: If the rule set is a regular rule set, do the following:
+ *
+ * <ul>
+ * <li>If the rule set includes a master rule (and the number was passed in as a <tt>double</tt>),
+ * use the master rule. (If the number being formatted was passed in as a <tt>long</tt>,
+ * the master rule is ignored.)</li>
+ * <li>If the number is negative, use the negative-number rule.</li>
+ * <li>If the number has a fractional part and is greater than 1, use the improper fraction
+ * rule.</li>
+ * <li>If the number has a fractional part and is between 0 and 1, use the proper fraction
+ * rule.</li>
+ * <li>Binary-search the rule list for the rule with the highest base value less than or equal
+ * to the number. If that rule has two substitutions, its base value is not an even multiple
+ * of its divisor, and the number <em>is</em> an even multiple of the rule's divisor, use the
+ * rule that precedes it in the rule list. Otherwise, use the rule itself.</li>
+ * </ul>
+ *
+ * <p>If the rule set is a fraction rule set, do the following:
+ *
+ * <ul>
+ * <li>Ignore negative-number and fraction rules.</li>
+ * <li>For each rule in the list, multiply the number being formatted (which will always be
+ * between 0 and 1) by the rule's base value. Keep track of the distance between the result
+ * the nearest integer.</li>
+ * <li>Use the rule that produced the result closest to zero in the above calculation. In the
+ * event of a tie or a direct hit, use the first matching rule encountered. (The idea here is
+ * to try each rule's base value as a possible denominator of a fraction. Whichever
+ * denominator produces the fraction closest in value to the number being formatted wins.) If
+ * the rule following the matching rule has the same base value, use it if the numerator of
+ * the fraction is anything other than 1; if the numerator is 1, use the original matching
+ * rule. (This is to allow singular and plural forms of the rule text without a lot of extra
+ * hassle.)</li>
+ * </ul>
+ *
+ * <p>A rule's body consists of a string of characters terminated by a semicolon. The rule
+ * may include zero, one, or two <em>substitution tokens,</em> and a range of text in
+ * brackets. The brackets denote optional text (and may also include one or both
+ * substitutions). The exact meanings of the substitution tokens, and under what conditions
+ * optional text is omitted, depend on the syntax of the substitution token and the context.
+ * The rest of the text in a rule body is literal text that is output when the rule matches
+ * the number being formatted.</p>
+ *
+ * <p>A substitution token begins and ends with a <em>token character.</em> The token
+ * character and the context together specify a mathematical operation to be performed on the
+ * number being formatted. An optional <em>substitution descriptor </em>specifies how the
+ * value resulting from that operation is used to fill in the substitution. The position of
+ * the substitution token in the rule body specifies the location of the resultant text in
+ * the original rule text.</p>
+ *
+ * <p>The meanings of the substitution token characters are as follows:</p>

+ * <p><b>Localizations</b></p>
+ * <p>Constructors are available that allow the specification of localizations for the
+ * public rule sets (and also allow more control over what public rule sets are available).
+ * Localization data is represented as a textual description. The description represents
+ * an array of arrays of string. The first element is an array of the public rule set names,
+ * each of these must be one of the public rule set names that appear in the rules. Only
+ * names in this array will be treated as public rule set names by the API. Each subsequent
+ * element is an array of localizations of these names. The first element of one of these
+ * subarrays is the locale name, and the remaining elements are localizations of the
+ * public rule set names, in the same order as they were listed in the first arrray.</p>
+ * <p>In the syntax, angle brackets '<', '>' are used to delimit the arrays, and comma ',' is used
+ * to separate elements of an array. Whitespace is ignored, unless quoted.</p>
+ * <p>For example:<pre>
+ * < < %foo, %bar, %baz >,
+ * < en, Foo, Bar, Baz >,
+ * < fr, 'le Foo', 'le Bar', 'le Baz' >

- * \file
- * \brief C++ API: Regular Expressions
- *
- * <h2>Regular Expression API</h2>
- *
- * <p>The ICU API for processing regular expressions consists of two classes,
- * <code>RegexPattern</code> and <code>RegexMatcher</code>.
- * <code>RegexPattern</code> objects represent a pre-processed, or compiled
- * regular expression. They are created from a regular expression pattern string,
- * and can be used to create <code>RegexMatcher</code> objects for the pattern.</p>
- *
- * <p>Class <code>RegexMatcher</code> bundles together a regular expression
- * pattern and a target string to which the search pattern will be applied.
- * <code>RegexMatcher</code> includes API for doing plain find or search
- * operations, for search and replace operations, and for obtaining detailed
- * information about bounds of a match. </p>
- *
- * <p>Note that by constructing <code>RegexMatcher</code> objects directly from regular
- * expression pattern strings application code can be simplified and the explicit
- * need for <code>RegexPattern</code> objects can usually be eliminated.
- * </p>

-/**
- * <code>Replaceable</code> is an abstract base class representing a
- * string of characters that supports the replacement of a range of
- * itself with a new string of characters. It is used by APIs that
- * change a piece of text while retaining metadata. Metadata is data
- * other than the Unicode characters returned by char32At(). One
- * example of metadata is style attributes; another is an edit
- * history, marking each character with an author and revision number.
- *
- * <p>An implicit aspect of the <code>Replaceable</code> API is that
- * during a replace operation, new characters take on the metadata of
- * the old characters. For example, if the string "the <b>bold</b>
- * font" has range (4, 8) replaced with "strong", then it becomes "the
- * <b>strong</b> font".
- *
- * <p><code>Replaceable</code> specifies ranges using a start
- * offset and a limit offset. The range of characters thus specified
- * includes the characters at offset start..limit-1. That is, the
- * start offset is inclusive, and the limit offset is exclusive.
- *
- * <p><code>Replaceable</code> also includes API to access characters
- * in the string: <code>length()</code>, <code>charAt()</code>,
- * <code>char32At()</code>, and <code>extractBetween()</code>.
- *
- * <p>For a subclass to support metadata, typical behavior of
- * <code>replace()</code> is the following:
- * <ul>
- * <li>Set the metadata of the new text to the metadata of the first
- * character replaced</li>
- * <li>If no characters are replaced, use the metadata of the
- * previous character</li>
- * <li>If there is no previous character (i.e. start == 0), use the
- * following character</li>
- * <li>If there is no following character (i.e. the replaceable was
- * empty), use default metadata.<br>
- * <li>If the code point U+FFFF is seen, it should be interpreted as
- * a special marker having no metadata<li>
- * </li>
- * </ul>
- * If this is not the behavior, the subclass should document any differences.

- * <tt>SearchIterator</tt> is an abstract base class that provides
- * methods to search for a pattern within a text string. Instances of
- * <tt>SearchIterator</tt> maintain a current position and scans over the
- * target text, returning the indices the pattern is matched and the length
- * of each match.
- * <p>
- * <tt>SearchIterator</tt> defines a protocol for text searching.
- * Subclasses provide concrete implementations of various search algorithms.
- * For example, <tt>StringSearch</tt> implements language-sensitive pattern
- * matching based on the comparison rules defined in a
- * <tt>RuleBasedCollator</tt> object.
- * <p>
- * Other options for searching includes using a BreakIterator to restrict
- * the points at which matches are detected.
- * <p>
- * <tt>SearchIterator</tt> provides an API that is similar to that of
- * other text iteration classes such as <tt>BreakIterator</tt>. Using
- * this class, it is easy to scan through text looking for all occurances of
- * a given pattern. The following example uses a <tt>StringSearch</tt>
- * object to find all instances of "fox" in the target string. Any other
- * subclass of <tt>SearchIterator</tt> can be used in an identical
- * manner.
- * <pre><code>
- * UnicodeString target("The quick brown fox jumped over the lazy fox");
- * UnicodeString pattern("fox");
- *
- * SearchIterator *iter = new StringSearch(pattern, target);
- * UErrorCode error = U_ZERO_ERROR;
- * for (int pos = iter->first(error); pos != USEARCH_DONE;
- * pos = iter->next(error)) {

-/**
- *
- * SimpleDateFormat is a concrete class for formatting and parsing dates in a
- * language-independent manner. It allows for formatting (millis -> text),
- * parsing (text -> millis), and normalization. Formats/Parses a date or time,
- * which is the standard milliseconds since 24:00 GMT, Jan 1, 1970.
- * <P>
- * Clients are encouraged to create a date-time formatter using DateFormat::getInstance(),
- * getDateInstance(), getDateInstance(), or getDateTimeInstance() rather than
- * explicitly constructing an instance of SimpleDateFormat. This way, the client
- * is guaranteed to get an appropriate formatting pattern for whatever locale the
- * program is running in. However, if the client needs something more unusual than
- * the default patterns in the locales, he can construct a SimpleDateFormat directly
- * and give it an appropriate pattern (or use one of the factory methods on DateFormat
- * and modify the pattern after the fact with toPattern() and applyPattern().
- * <P>
- * Date/Time format syntax:
- * <P>
- * The date/time format is specified by means of a string time pattern. In this
- * pattern, all ASCII letters are reserved as pattern letters, which are defined
- * as the following:
- * <pre>
- * \code
- * Symbol Meaning Presentation Example
- * ------ ------- ------------ -------

- * (Text): 4 or more, use full form, <4, use short or abbreviated form if it
- * exists. (e.g., "EEEE" produces "Monday", "EEE" produces "Mon")
- * <P>
- * (Number): the minimum number of digits. Shorter numbers are zero-padded to
- * this amount (e.g. if "m" produces "6", "mm" produces "06"). Year is handled
- * specially; that is, if the count of 'y' is 2, the Year will be truncated to 2 digits.
- * (e.g., if "yyyy" produces "1997", "yy" produces "97".)
- * Unlike other fields, fractional seconds are padded on the right with zero.
- * <P>
- * (Text & Number): 3 or over, use text, otherwise use number. (e.g., "M" produces "1",
- * "MM" produces "01", "MMM" produces "Jan", and "MMMM" produces "January".)
- * <P>
- * Any characters in the pattern that are not in the ranges of ['a'..'z'] and
- * ['A'..'Z'] will be treated as quoted text. For instance, characters
- * like ':', '.', ' ', '#' and '@' will appear in the resulting time text
- * even they are not embraced within single quotes.
- * <P>
- * A pattern containing any invalid pattern letter will result in a failing
- * UErrorCode result during formatting or parsing.
- * <P>
- * Examples using the US locale:
- * <pre>
- * \code
- * Format Pattern Result
- * -------------- -------
- * "yyyy.MM.dd G 'at' HH:mm:ss vvvv" ->> 1996.07.10 AD at 15:08:56 Pacific Time
- * "EEE, MMM d, ''yy" ->> Wed, July 10, '96
- * "h:mm a" ->> 12:08 PM
- * "hh 'o''clock' a, zzzz" ->> 12 o'clock PM, Pacific Daylight Time
- * "K:mm a, vvv" ->> 0:00 PM, PT
- * "yyyyy.MMMMM.dd GGG hh:mm aaa" ->> 1996.July.10 AD 12:08 PM
- * \endcode
- * </pre>
- * Code Sample:
- * <pre>
- * \code
- * UErrorCode success = U_ZERO_ERROR;
- * SimpleTimeZone* pdt = new SimpleTimeZone(-8 * 60 * 60 * 1000, "PST");
- * pdt->setStartRule( Calendar::APRIL, 1, Calendar::SUNDAY, 2*60*60*1000);
- * pdt->setEndRule( Calendar::OCTOBER, -1, Calendar::SUNDAY, 2*60*60*1000);
- *
- * // Format the current time.
- * SimpleDateFormat* formatter
- * = new SimpleDateFormat ("yyyy.MM.dd G 'at' hh:mm:ss a zzz", success );
- * GregorianCalendar cal(success);
- * UDate currentTime_1 = cal.getTime(success);
- * FieldPosition fp(0);
- * UnicodeString dateString;
- * formatter->format( currentTime_1, dateString, fp );
- * cout << "result: " << dateString << endl;
- *
- * // Parse the previous string back into a Date.
- * ParsePosition pp(0);
- * UDate currentTime_2 = formatter->parse(dateString, pp );
- * \endcode
- * </pre>
- * In the above example, the time value "currentTime_2" obtained from parsing
- * will be equal to currentTime_1. However, they may not be equal if the am/pm
- * marker 'a' is left out from the format pattern while the "hour in am/pm"
- * pattern symbol is used. This information loss can happen when formatting the
- * time in PM.
- *
- * <p>
- * When parsing a date string using the abbreviated year pattern ("y" or "yy"),
- * SimpleDateFormat must interpret the abbreviated year
- * relative to some century. It does this by adjusting dates to be
- * within 80 years before and 20 years after the time the SimpleDateFormat
- * instance is created. For example, using a pattern of "MM/dd/yy" and a
- * SimpleDateFormat instance created on Jan 1, 1997, the string
- * "01/11/12" would be interpreted as Jan 11, 2012 while the string "05/04/64"
- * would be interpreted as May 4, 1964.
- * During parsing, only strings consisting of exactly two digits, as defined by
- * <code>Unicode::isDigit()</code>, will be parsed into the default century.
- * Any other numeric string, such as a one digit string, a three or more digit
- * string, or a two digit string that isn't all digits (for example, "-1"), is
- * interpreted literally. So "01/02/3" or "01/02/003" are parsed, using the
- * same pattern, as Jan 2, 3 AD. Likewise, "01/02/-3" is parsed as Jan 2, 4 BC.
- *
- * <p>
- * If the year pattern has more than two 'y' characters, the year is
- * interpreted literally, regardless of the number of digits. So using the
- * pattern "MM/dd/yyyy", "01/11/12" parses to Jan 11, 12 A.D.
- *
- * <p>
- * When numeric fields abut one another directly, with no intervening delimiter
- * characters, they constitute a run of abutting numeric fields. Such runs are
- * parsed specially. For example, the format "HHmmss" parses the input text
- * "123456" to 12:34:56, parses the input text "12345" to 1:23:45, and fails to
- * parse "1234". In other words, the leftmost field of the run is flexible,
- * while the others keep a fixed width. If the parse fails anywhere in the run,
- * then the leftmost field is shortened by one character, and the entire run is
- * parsed again. This is repeated until either the parse succeeds or the
- * leftmost field is one character in length. If the parse still fails at that
- * point, the parse of the run fails.
- *
- * <P>
- * For time zones that have no names, SimpleDateFormat uses strings GMT+hours:minutes or
- * GMT-hours:minutes.
- * <P>
- * The calendar defines what is the first day of the week, the first week of the
- * year, whether hours are zero based or not (0 vs 12 or 24), and the timezone.
- * There is one common number format to handle all the numbers; the digit count
- * is handled programmatically according to the pattern.
- *
- * <p><em>User subclasses are not supported.</em> While clients may write
- * subclasses, such code will not necessarily work and will not be
- * guaranteed to work stably from release to release.

+/**
+ *
+ * SimpleDateFormat is a concrete class for formatting and parsing dates in a
+ * language-independent manner. It allows for formatting (millis -> text),
+ * parsing (text -> millis), and normalization. Formats/Parses a date or time,
+ * which is the standard milliseconds since 24:00 GMT, Jan 1, 1970.
+ * <P>
+ * Clients are encouraged to create a date-time formatter using DateFormat::getInstance(),
+ * getDateInstance(), getDateInstance(), or getDateTimeInstance() rather than
+ * explicitly constructing an instance of SimpleDateFormat. This way, the client
+ * is guaranteed to get an appropriate formatting pattern for whatever locale the
+ * program is running in. However, if the client needs something more unusual than
+ * the default patterns in the locales, he can construct a SimpleDateFormat directly
+ * and give it an appropriate pattern (or use one of the factory methods on DateFormat
+ * and modify the pattern after the fact with toPattern() and applyPattern().
+ * <P>
+ * Date/Time format syntax:
+ * <P>
+ * The date/time format is specified by means of a string time pattern. In this
+ * pattern, all ASCII letters are reserved as pattern letters, which are defined
+ * as the following:
+ * <pre>
+ * \code
+ * Symbol Meaning Presentation Example
+ * ------ ------- ------------ -------
+ * G era designator (Text) AD
+ * y year (Number) 1996
+ * Y year (week of year) (Number) 1997
+ * u extended year (Number) 4601
+ * Q Quarter (Text & Number) Q2 & 02
+ * M month in year (Text & Number) July & 07
+ * d day in month (Number) 10
+ * h hour in am/pm (1~12) (Number) 12
+ * H hour in day (0~23) (Number) 0
+ * m minute in hour (Number) 30
+ * s second in minute (Number) 55
+ * S fractional second (Number) 978
+ * E day of week (Text) Tuesday
+ * e day of week (local 1~7) (Text & Number) Tues & 2
+ * D day in year (Number) 189
+ * F day of week in month (Number) 2 (2nd Wed in July)
+ * w week in year (Number) 27
+ * W week in month (Number) 2
+ * a am/pm marker (Text) PM
+ * k hour in day (1~24) (Number) 24
+ * K hour in am/pm (0~11) (Number) 0
+ * z time zone (Time) Pacific Standard Time
+ * Z time zone (RFC 822) (Number) -0800
+ * v time zone (generic) (Text) Pacific Time
+ * V time zone (abreviation) (Text) PT
+ * VVVV time zone (location) (Text) United States (Los Angeles)
+ * g Julian day (Number) 2451334
+ * A milliseconds in day (Number) 69540000
+ * q stand alone quarter (Text & Number) Q2 & 02
+ * L stand alone month (Text & Number) July & 07
+ * c stand alone day of week (Text & Number) Tuesday & 2
+ * ' escape for text (Delimiter) 'Date='
+ * '' single quote (Literal) 'o''clock'
+ * \endcode
+ * </pre>
+ * The count of pattern letters determine the format.
+ * <P>
+ * (Text): 4 or more, use full form, <4, use short or abbreviated form if it
+ * exists. (e.g., "EEEE" produces "Monday", "EEE" produces "Mon")
+ * <P>
+ * (Number): the minimum number of digits. Shorter numbers are zero-padded to
+ * this amount (e.g. if "m" produces "6", "mm" produces "06"). Year is handled
+ * specially; that is, if the count of 'y' is 2, the Year will be truncated to 2 digits.
+ * (e.g., if "yyyy" produces "1997", "yy" produces "97".)
+ * Unlike other fields, fractional seconds are padded on the right with zero.
+ * <P>
+ * (Text & Number): 3 or over, use text, otherwise use number. (e.g., "M" produces "1",
+ * "MM" produces "01", "MMM" produces "Jan", and "MMMM" produces "January".)
+ * <P>
+ * Any characters in the pattern that are not in the ranges of ['a'..'z'] and
+ * ['A'..'Z'] will be treated as quoted text. For instance, characters
+ * like ':', '.', ' ', '#' and '@' will appear in the resulting time text
+ * even they are not embraced within single quotes.
+ * <P>
+ * A pattern containing any invalid pattern letter will result in a failing
+ * UErrorCode result during formatting or parsing.
+ * <P>
+ * Examples using the US locale:
+ * <pre>
+ * \code
+ * Format Pattern Result
+ * -------------- -------
+ * "yyyy.MM.dd G 'at' HH:mm:ss vvvv" ->> 1996.07.10 AD at 15:08:56 Pacific Time
+ * "EEE, MMM d, ''yy" ->> Wed, July 10, '96
+ * "h:mm a" ->> 12:08 PM
+ * "hh 'o''clock' a, zzzz" ->> 12 o'clock PM, Pacific Daylight Time
+ * "K:mm a, vvv" ->> 0:00 PM, PT
+ * "yyyyy.MMMMM.dd GGG hh:mm aaa" ->> 1996.July.10 AD 12:08 PM
+ * \endcode
+ * </pre>
+ * Code Sample:
+ * <pre>
+ * \code
+ * UErrorCode success = U_ZERO_ERROR;
+ * SimpleTimeZone* pdt = new SimpleTimeZone(-8 * 60 * 60 * 1000, "PST");
+ * pdt->setStartRule( Calendar::APRIL, 1, Calendar::SUNDAY, 2*60*60*1000);
+ * pdt->setEndRule( Calendar::OCTOBER, -1, Calendar::SUNDAY, 2*60*60*1000);
+ *
+ * // Format the current time.
+ * SimpleDateFormat* formatter
+ * = new SimpleDateFormat ("yyyy.MM.dd G 'at' hh:mm:ss a zzz", success );
+ * GregorianCalendar cal(success);
+ * UDate currentTime_1 = cal.getTime(success);
+ * FieldPosition fp(0);
+ * UnicodeString dateString;
+ * formatter->format( currentTime_1, dateString, fp );
+ * cout << "result: " << dateString << endl;
+ *
+ * // Parse the previous string back into a Date.
+ * ParsePosition pp(0);
+ * UDate currentTime_2 = formatter->parse(dateString, pp );
+ * \endcode
+ * </pre>
+ * In the above example, the time value "currentTime_2" obtained from parsing
+ * will be equal to currentTime_1. However, they may not be equal if the am/pm
+ * marker 'a' is left out from the format pattern while the "hour in am/pm"
+ * pattern symbol is used. This information loss can happen when formatting the
+ * time in PM.
+ *
+ * <p>
+ * When parsing a date string using the abbreviated year pattern ("y" or "yy"),
+ * SimpleDateFormat must interpret the abbreviated year
+ * relative to some century. It does this by adjusting dates to be
+ * within 80 years before and 20 years after the time the SimpleDateFormat
+ * instance is created. For example, using a pattern of "MM/dd/yy" and a
+ * SimpleDateFormat instance created on Jan 1, 1997, the string
+ * "01/11/12" would be interpreted as Jan 11, 2012 while the string "05/04/64"
+ * would be interpreted as May 4, 1964.
+ * During parsing, only strings consisting of exactly two digits, as defined by
+ * <code>Unicode::isDigit()</code>, will be parsed into the default century.
+ * Any other numeric string, such as a one digit string, a three or more digit
+ * string, or a two digit string that isn't all digits (for example, "-1"), is
+ * interpreted literally. So "01/02/3" or "01/02/003" are parsed, using the
+ * same pattern, as Jan 2, 3 AD. Likewise, "01/02/-3" is parsed as Jan 2, 4 BC.
+ *
+ * <p>
+ * If the year pattern has more than two 'y' characters, the year is
+ * interpreted literally, regardless of the number of digits. So using the
+ * pattern "MM/dd/yyyy", "01/11/12" parses to Jan 11, 12 A.D.
+ *
+ * <p>
+ * When numeric fields abut one another directly, with no intervening delimiter
+ * characters, they constitute a run of abutting numeric fields. Such runs are
+ * parsed specially. For example, the format "HHmmss" parses the input text
+ * "123456" to 12:34:56, parses the input text "12345" to 1:23:45, and fails to
+ * parse "1234". In other words, the leftmost field of the run is flexible,
+ * while the others keep a fixed width. If the parse fails anywhere in the run,
+ * then the leftmost field is shortened by one character, and the entire run is
+ * parsed again. This is repeated until either the parse succeeds or the
+ * leftmost field is one character in length. If the parse still fails at that
+ * point, the parse of the run fails.
+ *
+ * <P>
+ * For time zones that have no names, SimpleDateFormat uses strings GMT+hours:minutes or
+ * GMT-hours:minutes.
+ * <P>
+ * The calendar defines what is the first day of the week, the first week of the
+ * year, whether hours are zero based or not (0 vs 12 or 24), and the timezone.
+ * There is one common number format to handle all the numbers; the digit count
+ * is handled programmatically according to the pattern.
+ *
+ * <p><em>User subclasses are not supported.</em> While clients may write
+ * subclasses, such code will not necessarily work and will not be
+ * guaranteed to work stably from release to release.

-/**
- *
- * Collation keys are generated by the Collator class. Use the CollationKey objects
- * instead of Collator to compare strings multiple times. A CollationKey
- * preprocesses the comparison information from the Collator object to
- * make the comparison faster. If you are not going to comparing strings
- * multiple times, then using the Collator object is generally faster,
- * since it only processes as much of the string as needed to make a
- * comparison.
- * <p> For example (with strength == tertiary)
- * <p>When comparing "Abernathy" to "Baggins-Smythworthy", Collator
- * only needs to process a couple of characters, while a comparison
- * with CollationKeys will process all of the characters. On the other hand,
- * if you are doing a sort of a number of fields, it is much faster to use
- * CollationKeys, since you will be comparing strings multiple times.
- * <p>Typical use of CollationKeys are in databases, where you store a CollationKey
- * in a hidden field, and use it for sorting or indexing.
- *
- * <p>Example of use:
- * <pre>
- * \code
- * UErrorCode success = U_ZERO_ERROR;
- * Collator* myCollator = Collator::createInstance(success);
- * CollationKey* keys = new CollationKey [3];
- * myCollator->getCollationKey("Tom", keys[0], success );
- * myCollator->getCollationKey("Dick", keys[1], success );
- * myCollator->getCollationKey("Harry", keys[2], success );
- *
- * // Inside body of sort routine, compare keys this way:
- * CollationKey tmp;
- * if(keys[0].compareTo( keys[1] ) > 0 ) {
- * tmp = keys[0]; keys[0] = keys[1]; keys[1] = tmp;
- * }
- * //...
- * \endcode
- * </pre>
- * <p>Because Collator::compare()'s algorithm is complex, it is faster to sort
- * long lists of words by retrieving collation keys with Collator::getCollationKey().
- * You can then cache the collation keys and compare them using CollationKey::compareTo().
- * <p>
- * <strong>Note:</strong> <code>Collator</code>s with different Locale,
- * CollationStrength and DecompositionMode settings will return different
- * CollationKeys for the same set of strings. Locales have specific
- * collation rules, and the way in which secondary and tertiary differences
- * are taken into account, for example, will result in different CollationKeys
- * for same strings.

+/**
+ *
+ * Collation keys are generated by the Collator class. Use the CollationKey objects
+ * instead of Collator to compare strings multiple times. A CollationKey
+ * preprocesses the comparison information from the Collator object to
+ * make the comparison faster. If you are not going to comparing strings
+ * multiple times, then using the Collator object is generally faster,
+ * since it only processes as much of the string as needed to make a
+ * comparison.
+ * <p> For example (with strength == tertiary)
+ * <p>When comparing "Abernathy" to "Baggins-Smythworthy", Collator
+ * only needs to process a couple of characters, while a comparison
+ * with CollationKeys will process all of the characters. On the other hand,
+ * if you are doing a sort of a number of fields, it is much faster to use
+ * CollationKeys, since you will be comparing strings multiple times.
+ * <p>Typical use of CollationKeys are in databases, where you store a CollationKey
+ * in a hidden field, and use it for sorting or indexing.
+ *
+ * <p>Example of use:
+ * <pre>
+ * \code
+ * UErrorCode success = U_ZERO_ERROR;
+ * Collator* myCollator = Collator::createInstance(success);
+ * CollationKey* keys = new CollationKey [3];
+ * myCollator->getCollationKey("Tom", keys[0], success );
+ * myCollator->getCollationKey("Dick", keys[1], success );
+ * myCollator->getCollationKey("Harry", keys[2], success );
+ *
+ * // Inside body of sort routine, compare keys this way:
+ * CollationKey tmp;
+ * if(keys[0].compareTo( keys[1] ) > 0 ) {
+ * tmp = keys[0]; keys[0] = keys[1]; keys[1] = tmp;
+ * }
+ * //...
+ * \endcode
+ * </pre>
+ * <p>Because Collator::compare()'s algorithm is complex, it is faster to sort
+ * long lists of words by retrieving collation keys with Collator::getCollationKey().
+ * You can then cache the collation keys and compare them using CollationKey::compareTo().
+ * <p>
+ * <strong>Note:</strong> <code>Collator</code>s with different Locale,
+ * CollationStrength and DecompositionMode settings will return different
+ * CollationKeys for the same set of strings. Locales have specific
+ * collation rules, and the way in which secondary and tertiary differences
+ * are taken into account, for example, will result in different CollationKeys
+ * for same strings.

- * <p>The model is that the enumeration is over strings maintained by
- * a 'service.' At any point, the service might change, invalidating
- * the enumerator (though this is expected to be rare). The iterator
- * returns an error if this has occurred. Lack of the error is no
- * guarantee that the service didn't change immediately after the
- * call, so the returned string still might not be 'valid' on
- * subsequent use.</p>
- *
- * <p>Strings may take the form of const char*, const UChar*, or const
- * UnicodeString*. The type you get is determine by the variant of
- * 'next' that you call. In general the StringEnumeration is
- * optimized for one of these types, but all StringEnumerations can
- * return all types. Returned strings are each terminated with a NUL.
- * Depending on the service data, they might also include embedded NUL
- * characters, so API is provided to optionally return the true
- * length, counting the embedded NULs but not counting the terminating
- * NUL.</p>
- *

+ * <p>The model is that the enumeration is over strings maintained by
+ * a 'service.' At any point, the service might change, invalidating
+ * the enumerator (though this is expected to be rare). The iterator
+ * returns an error if this has occurred. Lack of the error is no

+ * call, so the returned string still might not be 'valid' on
+ * subsequent use.</p>
+ *
+ * <p>Strings may take the form of const char*, const UChar*, or const
+ * UnicodeString*. The type you get is determine by the variant of
+ * 'next' that you call. In general the StringEnumeration is
+ * optimized for one of these types, but all StringEnumerations can
+ * return all types. Returned strings are each terminated with a NUL.
+ * Depending on the service data, they might also include embedded NUL
+ * characters, so API is provided to optionally return the true
+ * length, counting the embedded NULs but not counting the terminating
+ * NUL.</p>

-/**
- *
- * <tt>StringSearch</tt> is a <tt>SearchIterator</tt> that provides
- * language-sensitive text searching based on the comparison rules defined
- * in a {@link RuleBasedCollator} object.
- * StringSearch ensures that language eccentricity can be
- * handled, e.g. for the German collator, characters ß and SS will be matched
- * if case is chosen to be ignored.
- * See the <a href="http://source.icu-project.org/repos/icu/icuhtml/trunk/design/collation/ICU_collation_design.htm">
- * "ICU Collation Design Document"</a> for more information.
- * <p>
- * The algorithm implemented is a modified form of the Boyer Moore's search.
- * For more information see
- * <a href="http://icu-project.org/docs/papers/efficient_text_searching_in_java.html">
- * "Efficient Text Searching in Java"</a>, published in <i>Java Report</i>
- * in February, 1999, for further information on the algorithm.
- * <p>
- * There are 2 match options for selection:<br>
- * Let S' be the sub-string of a text string S between the offsets start and
- * end <start, end>.
- * <br>
- * A pattern string P matches a text string S at the offsets <start, end>
- * if
- * <pre>
- * option 1. Some canonical equivalent of P matches some canonical equivalent
- * of S'
- * option 2. P matches S' and if P starts or ends with a combining mark,
- * there exists no non-ignorable combining mark before or after S?
- * in S respectively.
- * </pre>
- * Option 2. will be the default.
- * <p>
- * This search has APIs similar to that of other text iteration mechanisms
- * such as the break iterators in <tt>BreakIterator</tt>. Using these
- * APIs, it is easy to scan through text looking for all occurances of
- * a given pattern. This search iterator allows changing of direction by
- * calling a <tt>reset</tt> followed by a <tt>next</tt> or <tt>previous</tt>.
- * Though a direction change can occur without calling <tt>reset</tt> first,
- * this operation comes with some speed penalty.
- * Match results in the forward direction will match the result matches in
- * the backwards direction in the reverse order
- * <p>
- * <tt>SearchIterator</tt> provides APIs to specify the starting position
- * within the text string to be searched, e.g. <tt>setOffset</tt>,
- * <tt>preceding</tt> and <tt>following</tt>. Since the
- * starting position will be set as it is specified, please take note that
- * there are some danger points which the search may render incorrect
- * results:
- * <ul>
- * <li> The midst of a substring that requires normalization.
- * <li> If the following match is to be found, the position should not be the
- * second character which requires to be swapped with the preceding
- * character. Vice versa, if the preceding match is to be found,
- * position to search from should not be the first character which
- * requires to be swapped with the next character. E.g certain Thai and
- * Lao characters require swapping.
- * <li> If a following pattern match is to be found, any position within a
- * contracting sequence except the first will fail. Vice versa if a
- * preceding pattern match is to be found, a invalid starting point
- * would be any character within a contracting sequence except the last.
- * </ul>
- * <p>
- * A breakiterator can be used if only matches at logical breaks are desired.
- * Using a breakiterator will only give you results that exactly matches the
- * boundaries given by the breakiterator. For instance the pattern "e" will
- * not be found in the string "\u00e9" if a character break iterator is used.
- * <p>
- * Options are provided to handle overlapping matches.
- * E.g. In English, overlapping matches produces the result 0 and 2
- * for the pattern "abab" in the text "ababab", where else mutually
- * exclusive matches only produce the result of 0.
- * <p>
- * Though collator attributes will be taken into consideration while
- * performing matches, there are no APIs here for setting and getting the
- * attributes. These attributes can be set by getting the collator
- * from <tt>getCollator</tt> and using the APIs in <tt>coll.h</tt>.
- * Lastly to update StringSearch to the new collator attributes,
- * reset() has to be called.
- * <p>
- * Restriction: <br>
- * Currently there are no composite characters that consists of a
- * character with combining class > 0 before a character with combining
- * class == 0. However, if such a character exists in the future,
- * StringSearch does not guarantee the results for option 1.
- * <p>
- * Consult the <tt>SearchIterator</tt> documentation for information on
- * and examples of how to use instances of this class to implement text
- * searching.
- * <pre><code>
- * UnicodeString target("The quick brown fox jumps over the lazy dog.");
- * UnicodeString pattern("fox");
- *
- * UErrorCode error = U_ZERO_ERROR;
- * StringSearch iter(pattern, target, Locale::getUS(), NULL, status);
- * for (int pos = iter.first(error);
- * pos != USEARCH_DONE;
- * pos = iter.next(error))
- * {
- * printf("Found match at %d pos, length is %d\n", pos,
- * iter.getMatchLength());
- * }
- * </code></pre>
- * <p>
- * Note, StringSearch is not to be subclassed.

+/**
+ *
+ * <tt>StringSearch</tt> is a <tt>SearchIterator</tt> that provides
+ * language-sensitive text searching based on the comparison rules defined
+ * in a {@link RuleBasedCollator} object.
+ * StringSearch ensures that language eccentricity can be
+ * handled, e.g. for the German collator, characters ß and SS will be matched
+ * if case is chosen to be ignored.
+ * See the <a href="http://source.icu-project.org/repos/icu/icuhtml/trunk/design/collation/ICU_collation_design.htm">
+ * "ICU Collation Design Document"</a> for more information.
+ * <p>
+ * The algorithm implemented is a modified form of the Boyer Moore's search.
+ * For more information see
+ * <a href="http://icu-project.org/docs/papers/efficient_text_searching_in_java.html">
+ * "Efficient Text Searching in Java"</a>, published in <i>Java Report</i>
+ * in February, 1999, for further information on the algorithm.
+ * <p>
+ * There are 2 match options for selection:<br>
+ * Let S' be the sub-string of a text string S between the offsets start and
+ * end <start, end>.
+ * <br>
+ * A pattern string P matches a text string S at the offsets <start, end>
+ * if
+ * <pre>
+ * option 1. Some canonical equivalent of P matches some canonical equivalent
+ * of S'
+ * option 2. P matches S' and if P starts or ends with a combining mark,
+ * there exists no non-ignorable combining mark before or after S?
+ * in S respectively.
+ * </pre>
+ * Option 2. will be the default.
+ * <p>
+ * This search has APIs similar to that of other text iteration mechanisms
+ * such as the break iterators in <tt>BreakIterator</tt>. Using these
+ * APIs, it is easy to scan through text looking for all occurances of
+ * a given pattern. This search iterator allows changing of direction by
+ * calling a <tt>reset</tt> followed by a <tt>next</tt> or <tt>previous</tt>.
+ * Though a direction change can occur without calling <tt>reset</tt> first,
+ * this operation comes with some speed penalty.
+ * Match results in the forward direction will match the result matches in
+ * the backwards direction in the reverse order
+ * <p>
+ * <tt>SearchIterator</tt> provides APIs to specify the starting position
+ * within the text string to be searched, e.g. <tt>setOffset</tt>,
+ * <tt>preceding</tt> and <tt>following</tt>. Since the
+ * starting position will be set as it is specified, please take note that
+ * there are some danger points which the search may render incorrect
+ * results:
+ * <ul>
+ * <li> The midst of a substring that requires normalization.
+ * <li> If the following match is to be found, the position should not be the
+ * second character which requires to be swapped with the preceding
+ * character. Vice versa, if the preceding match is to be found,
+ * position to search from should not be the first character which
+ * requires to be swapped with the next character. E.g certain Thai and
+ * Lao characters require swapping.
+ * <li> If a following pattern match is to be found, any position within a
+ * contracting sequence except the first will fail. Vice versa if a
+ * preceding pattern match is to be found, a invalid starting point
+ * would be any character within a contracting sequence except the last.
+ * </ul>
+ * <p>
+ * A breakiterator can be used if only matches at logical breaks are desired.
+ * Using a breakiterator will only give you results that exactly matches the
+ * boundaries given by the breakiterator. For instance the pattern "e" will
+ * not be found in the string "\u00e9" if a character break iterator is used.
+ * <p>
+ * Options are provided to handle overlapping matches.
+ * E.g. In English, overlapping matches produces the result 0 and 2
+ * for the pattern "abab" in the text "ababab", where else mutually
+ * exclusive matches only produce the result of 0.
+ * <p>
+ * Though collator attributes will be taken into consideration while
+ * performing matches, there are no APIs here for setting and getting the
+ * attributes. These attributes can be set by getting the collator
+ * from <tt>getCollator</tt> and using the APIs in <tt>coll.h</tt>.
+ * Lastly to update StringSearch to the new collator attributes,
+ * reset() has to be called.
+ * <p>
+ * Restriction: <br>
+ * Currently there are no composite characters that consists of a
+ * character with combining class > 0 before a character with combining
+ * class == 0. However, if such a character exists in the future,
+ * StringSearch does not guarantee the results for option 1.
+ * <p>
+ * Consult the <tt>SearchIterator</tt> documentation for information on
+ * and examples of how to use instances of this class to implement text
+ * searching.
+ * <pre><code>
+ * UnicodeString target("The quick brown fox jumps over the lazy dog.");
+ * UnicodeString pattern("fox");
+ *
+ * UErrorCode error = U_ZERO_ERROR;
+ * StringSearch iter(pattern, target, Locale::getUS(), NULL, status);
+ * for (int pos = iter.first(error);
+ * pos != USEARCH_DONE;
+ * pos = iter.next(error))
+ * {
+ * printf("Found match at %d pos, length is %d\n", pos,
+ * iter.getMatchLength());
+ * }
+ * </code></pre>
+ * <p>
+ * Note, StringSearch is not to be subclassed.

-* Created by: Helena Shih
-*
-* Modification History:
-*
-* Date Name Description
-* 2/5/97 aliu Added streamIn and streamOut methods. Added
-* constructor which reads RuleBasedCollator object from
-* a binary file. Added writeToFile method which streams
-* RuleBasedCollator out to a binary file. The streamIn
-* and streamOut methods use istream and ostream objects
-* in binary mode.
-* 2/12/97 aliu Modified to use TableCollationData sub-object to
-* hold invariant data.
-* 2/13/97 aliu Moved several methods into this class from Collation.
-* Added a private RuleBasedCollator(Locale&) constructor,
-* to be used by Collator::createDefault(). General
-* clean up.
-* 2/20/97 helena Added clone, operator==, operator!=, operator=, and copy
-* constructor and getDynamicClassID.
-* 3/5/97 aliu Modified constructFromFile() to add parameter
-* specifying whether or not binary loading is to be
-* attempted. This is required for dynamic rule loading.
-* 05/07/97 helena Added memory allocation error detection.
-* 6/17/97 helena Added IDENTICAL strength for compare, changed getRules to
-* use MergeCollation::getPattern.
-* 6/20/97 helena Java class name change.
-* 8/18/97 helena Added internal API documentation.
-* 09/03/97 helena Added createCollationKeyValues().
-* 02/10/98 damiba Added compare with "length" parameter
-* 08/05/98 erm Synched with 1.2 version of RuleBasedCollator.java
-* 04/23/99 stephen Removed EDecompositionMode, merged with
-* Normalizer::EMode
-* 06/14/99 stephen Removed kResourceBundleSuffix
-* 11/02/99 helena Collator performance enhancements. Eliminates the
-* UnicodeString construction and special case for NO_OP.
-* 11/23/99 srl More performance enhancements. Updates to NormalizerIterator
-* internal state management.

- * The RuleBasedCollator class provides the simple implementation of

- * <P>
- * <em>Important: </em>The ICU collation service has been reimplemented
- * in order to achieve better performance and UCA compliance.
- * For details, see the
- * <a href="http://source.icu-project.org/repos/icu/icuhtml/trunk/design/collation/ICU_collation_design.htm">
- * collation design document</a>.
- * <p>
- * RuleBasedCollator is a thin C++ wrapper over the C implementation.
- * <p>
- * For more information about the collation service see
- * <a href="http://icu-project.org/userguide/Collate_Intro.html">the users guide</a>.
- * <p>
- * Collation service provides correct sorting orders for most locales supported in ICU.
- * If specific data for a locale is not available, the orders eventually falls back
- * to the <a href="http://www.unicode.org/unicode/reports/tr10/">UCA sort order</a>.
- * <p>
- * Sort ordering may be customized by providing your own set of rules. For more on
- * this subject see the <a href="http://icu-project.org/userguide/Collate_Customization.html">
- * Collation customization</a> section of the users guide.
- * <p>
- * Note, RuleBasedCollator is not to be subclassed.

+* 2/12/97 aliu Modified to use TableCollationData sub-object to
+* hold invariant data.
+* 2/13/97 aliu Moved several methods into this class from Collation.
+* Added a private RuleBasedCollator(Locale&) constructor,
+* to be used by Collator::createDefault(). General
+* clean up.
+* 2/20/97 helena Added clone, operator==, operator!=, operator=, and copy
+* constructor and getDynamicClassID.
+* 3/5/97 aliu Modified constructFromFile() to add parameter
+* specifying whether or not binary loading is to be
+* attempted. This is required for dynamic rule loading.
+* 05/07/97 helena Added memory allocation error detection.
+* 6/17/97 helena Added IDENTICAL strength for compare, changed getRules to
+* use MergeCollation::getPattern.
+* 6/20/97 helena Java class name change.
+* 8/18/97 helena Added internal API documentation.
+* 09/03/97 helena Added createCollationKeyValues().

+* 04/23/99 stephen Removed EDecompositionMode, merged with
+* Normalizer::EMode
+* 06/14/99 stephen Removed kResourceBundleSuffix
+* 11/02/99 helena Collator performance enhancements. Eliminates the
+* UnicodeString construction and special case for NO_OP.
+* 11/23/99 srl More performance enhancements. Updates to NormalizerIterator

+ * in order to achieve better performance and UCA compliance.
+ * For details, see the
+ * <a href="http://source.icu-project.org/repos/icu/icuhtml/trunk/design/collation/ICU_collation_design.htm">
+ * collation design document</a>.
+ * <p>

+ * For more information about the collation service see
+ * <a href="http://icu-project.org/userguide/Collate_Intro.html">the users guide</a>.
+ * <p>
+ * Collation service provides correct sorting orders for most locales supported in ICU.
+ * If specific data for a locale is not available, the orders eventually falls back
+ * to the <a href="http://www.unicode.org/unicode/reports/tr10/">UCA sort order</a>.
+ * <p>
+ * Sort ordering may be customized by providing your own set of rules. For more on
+ * this subject see the <a href="http://icu-project.org/userguide/Collate_Customization.html">

-/**
- *
- * <code>TimeZone</code> represents a time zone offset, and also figures out daylight
- * savings.
- *
- * <p>
- * Typically, you get a <code>TimeZone</code> using <code>createDefault</code>
- * which creates a <code>TimeZone</code> based on the time zone where the program
- * is running. For example, for a program running in Japan, <code>createDefault</code>
- * creates a <code>TimeZone</code> object based on Japanese Standard Time.
- *
- * <p>
- * You can also get a <code>TimeZone</code> using <code>createTimeZone</code> along
- * with a time zone ID. For instance, the time zone ID for the Pacific
- * Standard Time zone is "PST". So, you can get a PST <code>TimeZone</code> object
- * with:
- * \htmlonly<blockquote>\endhtmlonly
- * <pre>
- * TimeZone *tz = TimeZone::createTimeZone("PST");
- * </pre>
- * \htmlonly</blockquote>\endhtmlonly
- * You can use <code>getAvailableIDs</code> method to iterate through
- * all the supported time zone IDs. You can then choose a
- * supported ID to get a <code>TimeZone</code>.
- * If the time zone you want is not represented by one of the
- * supported IDs, then you can create a custom time zone ID with
- * the following syntax:
- *
- * \htmlonly<blockquote>\endhtmlonly
- * <pre>
- * GMT[+|-]hh[[:]mm]
- * </pre>
- * \htmlonly</blockquote>\endhtmlonly
- *
- * For example, you might specify GMT+14:00 as a custom
- * time zone ID. The <code>TimeZone</code> that is returned
- * when you specify a custom time zone ID does not include
- * daylight savings time.
- *
- * TimeZone is an abstract class representing a time zone. A TimeZone is needed for
- * Calendar to produce local time for a particular time zone. A TimeZone comprises
- * three basic pieces of information:
- * <ul>
- * <li>A time zone offset; that, is the number of milliseconds to add or subtract
- * from a time expressed in terms of GMT to convert it to the same time in that
- * time zone (without taking daylight savings time into account).</li>
- * <li>Logic necessary to take daylight savings time into account if daylight savings
- * time is observed in that time zone (e.g., the days and hours on which daylight
- * savings time begins and ends).</li>
- * <li>An ID. This is a text string that uniquely identifies the time zone.</li>
- * </ul>
- *
- * (Only the ID is actually implemented in TimeZone; subclasses of TimeZone may handle
- * daylight savings time and GMT offset in different ways. Currently we only have one
- * TimeZone subclass: SimpleTimeZone.)
- * <P>
- * The TimeZone class contains a static list containing a TimeZone object for every
- * combination of GMT offset and daylight-savings time rules currently in use in the
- * world, each with a unique ID. Each ID consists of a region (usually a continent or
- * ocean) and a city in that region, separated by a slash, (for example, Pacific
- * Standard Time is "America/Los_Angeles.") Because older versions of this class used
- * three- or four-letter abbreviations instead, there is also a table that maps the older
- * abbreviations to the newer ones (for example, "PST" maps to "America/LosAngeles").
- * Anywhere the API requires an ID, you can use either form.
- * <P>
- * To create a new TimeZone, you call the factory function TimeZone::createTimeZone()
- * and pass it a time zone ID. You can use the createEnumeration() function to
- * obtain a list of all the time zone IDs recognized by createTimeZone().
- * <P>
- * You can also use TimeZone::createDefault() to create a TimeZone. This function uses
- * platform-specific APIs to produce a TimeZone for the time zone corresponding to
- * the client's computer's physical location. For example, if you're in Japan (assuming
- * your machine is set up correctly), TimeZone::createDefault() will return a TimeZone
- * for Japanese Standard Time ("Asia/Tokyo").

+ *
+ * <code>TimeZone</code> represents a time zone offset, and also figures out daylight
+ * savings.
+ *
+ * <p>
+ * Typically, you get a <code>TimeZone</code> using <code>createDefault</code>
+ * which creates a <code>TimeZone</code> based on the time zone where the program
+ * is running. For example, for a program running in Japan, <code>createDefault</code>
+ * creates a <code>TimeZone</code> object based on Japanese Standard Time.
+ *
+ * <p>
+ * You can also get a <code>TimeZone</code> using <code>createTimeZone</code> along
+ * with a time zone ID. For instance, the time zone ID for the Pacific
+ * Standard Time zone is "PST". So, you can get a PST <code>TimeZone</code> object
+ * with:
+ * \htmlonly<blockquote>\endhtmlonly
+ * <pre>
+ * TimeZone *tz = TimeZone::createTimeZone("PST");
+ * </pre>
+ * \htmlonly</blockquote>\endhtmlonly
+ * You can use <code>getAvailableIDs</code> method to iterate through
+ * all the supported time zone IDs. You can then choose a
+ * supported ID to get a <code>TimeZone</code>.
+ * If the time zone you want is not represented by one of the
+ * supported IDs, then you can create a custom time zone ID with
+ * the following syntax:
+ *
+ * \htmlonly<blockquote>\endhtmlonly
+ * <pre>
+ * GMT[+|-]hh[[:]mm]
+ * </pre>
+ * \htmlonly</blockquote>\endhtmlonly
+ *
+ * For example, you might specify GMT+14:00 as a custom
+ * time zone ID. The <code>TimeZone</code> that is returned
+ * when you specify a custom time zone ID does not include
+ * daylight savings time.
+ *
+ * TimeZone is an abstract class representing a time zone. A TimeZone is needed for
+ * Calendar to produce local time for a particular time zone. A TimeZone comprises
+ * three basic pieces of information:
+ * <ul>
+ * <li>A time zone offset; that, is the number of milliseconds to add or subtract
+ * from a time expressed in terms of GMT to convert it to the same time in that
+ * time zone (without taking daylight savings time into account).</li>
+ * <li>Logic necessary to take daylight savings time into account if daylight savings
+ * time is observed in that time zone (e.g., the days and hours on which daylight
+ * savings time begins and ends).</li>
+ * <li>An ID. This is a text string that uniquely identifies the time zone.</li>
+ * </ul>
+ *
+ * (Only the ID is actually implemented in TimeZone; subclasses of TimeZone may handle
+ * daylight savings time and GMT offset in different ways. Currently we only have one
+ * TimeZone subclass: SimpleTimeZone.)
+ * <P>
+ * The TimeZone class contains a static list containing a TimeZone object for every
+ * combination of GMT offset and daylight-savings time rules currently in use in the
+ * world, each with a unique ID. Each ID consists of a region (usually a continent or
+ * ocean) and a city in that region, separated by a slash, (for example, Pacific
+ * Standard Time is "America/Los_Angeles.") Because older versions of this class used
+ * three- or four-letter abbreviations instead, there is also a table that maps the older
+ * abbreviations to the newer ones (for example, "PST" maps to "America/LosAngeles").
+ * Anywhere the API requires an ID, you can use either form.
+ * <P>
+ * To create a new TimeZone, you call the factory function TimeZone::createTimeZone()
+ * and pass it a time zone ID. You can use the createEnumeration() function to
+ * obtain a list of all the time zone IDs recognized by createTimeZone().
+ * <P>
+ * You can also use TimeZone::createDefault() to create a TimeZone. This function uses
+ * platform-specific APIs to produce a TimeZone for the time zone corresponding to
+ * the client's computer's physical location. For example, if you're in Japan (assuming
+ * your machine is set up correctly), TimeZone::createDefault() will return a TimeZone
+ * for Japanese Standard Time ("Asia/Tokyo").

-/**
- *
- * <code>Transliterator</code> is an abstract class that
- * transliterates text from one format to another. The most common
- * kind of transliterator is a script, or alphabet, transliterator.
- * For example, a Russian to Latin transliterator changes Russian text
- * written in Cyrillic characters to phonetically equivalent Latin
- * characters. It does not <em>translate</em> Russian to English!
- * Transliteration, unlike translation, operates on characters, without
- * reference to the meanings of words and sentences.
- *
- * <p>Although script conversion is its most common use, a
- * transliterator can actually perform a more general class of tasks.
- * In fact, <code>Transliterator</code> defines a very general API
- * which specifies only that a segment of the input text is replaced
- * by new text. The particulars of this conversion are determined
- * entirely by subclasses of <code>Transliterator</code>.
- *
- * <p><b>Transliterators are stateless</b>
- *
- * <p><code>Transliterator</code> objects are <em>stateless</em>; they
- * retain no information between calls to
- * <code>transliterate()</code>. (However, this does <em>not</em>
- * mean that threads may share transliterators without synchronizing
- * them. Transliterators are not immutable, so they must be
- * synchronized when shared between threads.) This might seem to
- * limit the complexity of the transliteration operation. In
- * practice, subclasses perform complex transliterations by delaying
- * the replacement of text until it is known that no other
- * replacements are possible. In other words, although the
- * <code>Transliterator</code> objects are stateless, the source text
- * itself embodies all the needed information, and delayed operation
- * allows arbitrary complexity.
- *
- * <p><b>Batch transliteration</b>
- *
- * <p>The simplest way to perform transliteration is all at once, on a
- * string of existing text. This is referred to as <em>batch</em>
- * transliteration. For example, given a string <code>input</code>
- * and a transliterator <code>t</code>, the call
- *
- * \htmlonly<blockquote>\endhtmlonly<code>String result = t.transliterate(input);
- * </code>\htmlonly</blockquote>\endhtmlonly
- *
- * will transliterate it and return the result. Other methods allow
- * the client to specify a substring to be transliterated and to use
- * {@link Replaceable } objects instead of strings, in order to
- * preserve out-of-band information (such as text styles).
- *
- * <p><b>Keyboard transliteration</b>
- *
- * <p>Somewhat more involved is <em>keyboard</em>, or incremental
- * transliteration. This is the transliteration of text that is
- * arriving from some source (typically the user's keyboard) one
- * character at a time, or in some other piecemeal fashion.
- *
- * <p>In keyboard transliteration, a <code>Replaceable</code> buffer
- * stores the text. As text is inserted, as much as possible is
- * transliterated on the fly. This means a GUI that displays the
- * contents of the buffer may show text being modified as each new
- * character arrives.
- *
- * <p>Consider the simple <code>RuleBasedTransliterator</code>:
- *
- * \htmlonly<blockquote>\endhtmlonly<code>
- * th>{theta}<br>
- * t>{tau}
- * </code>\htmlonly</blockquote>\endhtmlonly
- *
- * When the user types 't', nothing will happen, since the
- * transliterator is waiting to see if the next character is 'h'. To
- * remedy this, we introduce the notion of a cursor, marked by a '|'
- * in the output string:
- *
- * \htmlonly<blockquote>\endhtmlonly<code>
- * t>|{tau}<br>
- * {tau}h>{theta}
- * </code>\htmlonly</blockquote>\endhtmlonly
- *
- * Now when the user types 't', tau appears, and if the next character
- * is 'h', the tau changes to a theta. This is accomplished by
- * maintaining a cursor position (independent of the insertion point,
- * and invisible in the GUI) across calls to
- * <code>transliterate()</code>. Typically, the cursor will
- * be coincident with the insertion point, but in a case like the one
- * above, it will precede the insertion point.
- *
- * <p>Keyboard transliteration methods maintain a set of three indices
- * that are updated with each call to
- * <code>transliterate()</code>, including the cursor, start,
- * and limit. Since these indices are changed by the method, they are
- * passed in an <code>int[]</code> array. The <code>START</code> index
- * marks the beginning of the substring that the transliterator will
- * look at. It is advanced as text becomes committed (but it is not
- * the committed index; that's the <code>CURSOR</code>). The
- * <code>CURSOR</code> index, described above, marks the point at
- * which the transliterator last stopped, either because it reached
- * the end, or because it required more characters to disambiguate
- * between possible inputs. The <code>CURSOR</code> can also be
- * explicitly set by rules in a <code>RuleBasedTransliterator</code>.
- * Any characters before the <code>CURSOR</code> index are frozen;
- * future keyboard transliteration calls within this input sequence
- * will not change them. New text is inserted at the
- * <code>LIMIT</code> index, which marks the end of the substring that
- * the transliterator looks at.
- *
- * <p>Because keyboard transliteration assumes that more characters
- * are to arrive, it is conservative in its operation. It only
- * transliterates when it can do so unambiguously. Otherwise it waits
- * for more characters to arrive. When the client code knows that no
- * more characters are forthcoming, perhaps because the user has
- * performed some input termination operation, then it should call
- * <code>finishTransliteration()</code> to complete any
- * pending transliterations.
- *
- * <p><b>Inverses</b>
- *
- * <p>Pairs of transliterators may be inverses of one another. For
- * example, if transliterator <b>A</b> transliterates characters by
- * incrementing their Unicode value (so "abc" -> "def"), and
- * transliterator <b>B</b> decrements character values, then <b>A</b>
- * is an inverse of <b>B</b> and vice versa. If we compose <b>A</b>
- * with <b>B</b> in a compound transliterator, the result is the
- * indentity transliterator, that is, a transliterator that does not
- * change its input text.
- *
- * The <code>Transliterator</code> method <code>getInverse()</code>
- * returns a transliterator's inverse, if one exists, or
- * <code>null</code> otherwise. However, the result of
- * <code>getInverse()</code> usually will <em>not</em> be a true
- * mathematical inverse. This is because true inverse transliterators
- * are difficult to formulate. For example, consider two
- * transliterators: <b>AB</b>, which transliterates the character 'A'
- * to 'B', and <b>BA</b>, which transliterates 'B' to 'A'. It might
- * seem that these are exact inverses, since
- *
- * \htmlonly<blockquote>\endhtmlonly"A" x <b>AB</b> -> "B"<br>
- * "B" x <b>BA</b> -> "A"\htmlonly</blockquote>\endhtmlonly
- *
- * where 'x' represents transliteration. However,
- *
- * \htmlonly<blockquote>\endhtmlonly"ABCD" x <b>AB</b> -> "BBCD"<br>
- * "BBCD" x <b>BA</b> -> "AACD"\htmlonly</blockquote>\endhtmlonly
- *
- * so <b>AB</b> composed with <b>BA</b> is not the
- * identity. Nonetheless, <b>BA</b> may be usefully considered to be
- * <b>AB</b>'s inverse, and it is on this basis that
- * <b>AB</b><code>.getInverse()</code> could legitimately return
- * <b>BA</b>.
- *
- * <p><b>IDs and display names</b>
- *
- * <p>A transliterator is designated by a short identifier string or
- * <em>ID</em>. IDs follow the format <em>source-destination</em>,
- * where <em>source</em> describes the entity being replaced, and
- * <em>destination</em> describes the entity replacing
- * <em>source</em>. The entities may be the names of scripts,
- * particular sequences of characters, or whatever else it is that the
- * transliterator converts to or from. For example, a transliterator
- * from Russian to Latin might be named "Russian-Latin". A
- * transliterator from keyboard escape sequences to Latin-1 characters
- * might be named "KeyboardEscape-Latin1". By convention, system
- * entity names are in English, with the initial letters of words
- * capitalized; user entity names may follow any format so long as
- * they do not contain dashes.
- *
- * <p>In addition to programmatic IDs, transliterator objects have
- * display names for presentation in user interfaces, returned by
- * {@link #getDisplayName }.
- *
- * <p><b>Factory methods and registration</b>
- *
- * <p>In general, client code should use the factory method
- * {@link #createInstance } to obtain an instance of a
- * transliterator given its ID. Valid IDs may be enumerated using
- * <code>getAvailableIDs()</code>. Since transliterators are mutable,
- * multiple calls to {@link #createInstance } with the same ID will
- * return distinct objects.
- *
- * <p>In addition to the system transliterators registered at startup,
- * user transliterators may be registered by calling
- * <code>registerInstance()</code> at run time. A registered instance
- * acts a template; future calls to {@link #createInstance } with the ID
- * of the registered object return clones of that object. Thus any
- * object passed to <tt>registerInstance()</tt> must implement
- * <tt>clone()</tt> propertly. To register a transliterator subclass
- * without instantiating it (until it is needed), users may call
- * {@link #registerFactory }. In this case, the objects are
- * instantiated by invoking the zero-argument public constructor of
- * the class.
- *
- * <p><b>Subclassing</b>
- *
- * Subclasses must implement the abstract method
- * <code>handleTransliterate()</code>. <p>Subclasses should override
- * the <code>transliterate()</code> method taking a
- * <code>Replaceable</code> and the <code>transliterate()</code>
- * method taking a <code>String</code> and <code>StringBuffer</code>
- * if the performance of these methods can be improved over the
- * performance obtained by the default implementations in this class.

+
+/**
+ *
+ * <code>Transliterator</code> is an abstract class that
+ * transliterates text from one format to another. The most common
+ * kind of transliterator is a script, or alphabet, transliterator.
+ * For example, a Russian to Latin transliterator changes Russian text
+ * written in Cyrillic characters to phonetically equivalent Latin
+ * characters. It does not <em>translate</em> Russian to English!
+ * Transliteration, unlike translation, operates on characters, without
+ * reference to the meanings of words and sentences.
+ *
+ * <p>Although script conversion is its most common use, a
+ * transliterator can actually perform a more general class of tasks.
+ * In fact, <code>Transliterator</code> defines a very general API
+ * which specifies only that a segment of the input text is replaced
+ * by new text. The particulars of this conversion are determined
+ * entirely by subclasses of <code>Transliterator</code>.
+ *
+ * <p><b>Transliterators are stateless</b>
+ *
+ * <p><code>Transliterator</code> objects are <em>stateless</em>; they
+ * retain no information between calls to
+ * <code>transliterate()</code>. (However, this does <em>not</em>
+ * mean that threads may share transliterators without synchronizing
+ * them. Transliterators are not immutable, so they must be
+ * synchronized when shared between threads.) This might seem to
+ * limit the complexity of the transliteration operation. In
+ * practice, subclasses perform complex transliterations by delaying
+ * the replacement of text until it is known that no other
+ * replacements are possible. In other words, although the
+ * <code>Transliterator</code> objects are stateless, the source text
+ * itself embodies all the needed information, and delayed operation
+ * allows arbitrary complexity.
+ *
+ * <p><b>Batch transliteration</b>
+ *
+ * <p>The simplest way to perform transliteration is all at once, on a
+ * string of existing text. This is referred to as <em>batch</em>
+ * transliteration. For example, given a string <code>input</code>
+ * and a transliterator <code>t</code>, the call
+ *
+ * \htmlonly<blockquote>\endhtmlonly<code>String result = t.transliterate(input);
+ * </code>\htmlonly</blockquote>\endhtmlonly
+ *
+ * will transliterate it and return the result. Other methods allow
+ * the client to specify a substring to be transliterated and to use
+ * {@link Replaceable } objects instead of strings, in order to
+ * preserve out-of-band information (such as text styles).
+ *
+ * <p><b>Keyboard transliteration</b>
+ *
+ * <p>Somewhat more involved is <em>keyboard</em>, or incremental
+ * transliteration. This is the transliteration of text that is
+ * arriving from some source (typically the user's keyboard) one
+ * character at a time, or in some other piecemeal fashion.
+ *
+ * <p>In keyboard transliteration, a <code>Replaceable</code> buffer
+ * stores the text. As text is inserted, as much as possible is
+ * transliterated on the fly. This means a GUI that displays the
+ * contents of the buffer may show text being modified as each new
+ * character arrives.
+ *
+ * <p>Consider the simple <code>RuleBasedTransliterator</code>:
+ *
+ * \htmlonly<blockquote>\endhtmlonly<code>
+ * th>{theta}<br>
+ * t>{tau}
+ * </code>\htmlonly</blockquote>\endhtmlonly
+ *
+ * When the user types 't', nothing will happen, since the
+ * transliterator is waiting to see if the next character is 'h'. To
+ * remedy this, we introduce the notion of a cursor, marked by a '|'
+ * in the output string:
+ *
+ * \htmlonly<blockquote>\endhtmlonly<code>
+ * t>|{tau}<br>
+ * {tau}h>{theta}
+ * </code>\htmlonly</blockquote>\endhtmlonly
+ *
+ * Now when the user types 't', tau appears, and if the next character
+ * is 'h', the tau changes to a theta. This is accomplished by
+ * maintaining a cursor position (independent of the insertion point,
+ * and invisible in the GUI) across calls to
+ * <code>transliterate()</code>. Typically, the cursor will
+ * be coincident with the insertion point, but in a case like the one
+ * above, it will precede the insertion point.
+ *
+ * <p>Keyboard transliteration methods maintain a set of three indices
+ * that are updated with each call to
+ * <code>transliterate()</code>, including the cursor, start,
+ * and limit. Since these indices are changed by the method, they are
+ * passed in an <code>int[]</code> array. The <code>START</code> index
+ * marks the beginning of the substring that the transliterator will
+ * look at. It is advanced as text becomes committed (but it is not
+ * the committed index; that's the <code>CURSOR</code>). The
+ * <code>CURSOR</code> index, described above, marks the point at
+ * which the transliterator last stopped, either because it reached
+ * the end, or because it required more characters to disambiguate
+ * between possible inputs. The <code>CURSOR</code> can also be
+ * explicitly set by rules in a <code>RuleBasedTransliterator</code>.
+ * Any characters before the <code>CURSOR</code> index are frozen;
+ * future keyboard transliteration calls within this input sequence
+ * will not change them. New text is inserted at the
+ * <code>LIMIT</code> index, which marks the end of the substring that
+ * the transliterator looks at.
+ *
+ * <p>Because keyboard transliteration assumes that more characters
+ * are to arrive, it is conservative in its operation. It only
+ * transliterates when it can do so unambiguously. Otherwise it waits
+ * for more characters to arrive. When the client code knows that no
+ * more characters are forthcoming, perhaps because the user has
+ * performed some input termination operation, then it should call
+ * <code>finishTransliteration()</code> to complete any
+ * pending transliterations.
+ *
+ * <p><b>Inverses</b>
+ *
+ * <p>Pairs of transliterators may be inverses of one another. For
+ * example, if transliterator <b>A</b> transliterates characters by
+ * incrementing their Unicode value (so "abc" -> "def"), and
+ * transliterator <b>B</b> decrements character values, then <b>A</b>
+ * is an inverse of <b>B</b> and vice versa. If we compose <b>A</b>
+ * with <b>B</b> in a compound transliterator, the result is the
+ * indentity transliterator, that is, a transliterator that does not
+ * change its input text.
+ *
+ * The <code>Transliterator</code> method <code>getInverse()</code>
+ * returns a transliterator's inverse, if one exists, or
+ * <code>null</code> otherwise. However, the result of
+ * <code>getInverse()</code> usually will <em>not</em> be a true
+ * mathematical inverse. This is because true inverse transliterators
+ * are difficult to formulate. For example, consider two
+ * transliterators: <b>AB</b>, which transliterates the character 'A'
+ * to 'B', and <b>BA</b>, which transliterates 'B' to 'A'. It might
+ * seem that these are exact inverses, since
+ *
+ * \htmlonly<blockquote>\endhtmlonly"A" x <b>AB</b> -> "B"<br>
+ * "B" x <b>BA</b> -> "A"\htmlonly</blockquote>\endhtmlonly
+ *
+ * where 'x' represents transliteration. However,
+ *
+ * \htmlonly<blockquote>\endhtmlonly"ABCD" x <b>AB</b> -> "BBCD"<br>
+ * "BBCD" x <b>BA</b> -> "AACD"\htmlonly</blockquote>\endhtmlonly
+ *
+ * so <b>AB</b> composed with <b>BA</b> is not the
+ * identity. Nonetheless, <b>BA</b> may be usefully considered to be
+ * <b>AB</b>'s inverse, and it is on this basis that
+ * <b>AB</b><code>.getInverse()</code> could legitimately return
+ * <b>BA</b>.
+ *
+ * <p><b>IDs and display names</b>
+ *
+ * <p>A transliterator is designated by a short identifier string or
+ * <em>ID</em>. IDs follow the format <em>source-destination</em>,
+ * where <em>source</em> describes the entity being replaced, and
+ * <em>destination</em> describes the entity replacing
+ * <em>source</em>. The entities may be the names of scripts,
+ * particular sequences of characters, or whatever else it is that the
+ * transliterator converts to or from. For example, a transliterator
+ * from Russian to Latin might be named "Russian-Latin". A
+ * transliterator from keyboard escape sequences to Latin-1 characters
+ * might be named "KeyboardEscape-Latin1". By convention, system
+ * entity names are in English, with the initial letters of words
+ * capitalized; user entity names may follow any format so long as
+ * they do not contain dashes.
+ *
+ * <p>In addition to programmatic IDs, transliterator objects have
+ * display names for presentation in user interfaces, returned by
+ * {@link #getDisplayName }.
+ *
+ * <p><b>Factory methods and registration</b>
+ *
+ * <p>In general, client code should use the factory method
+ * {@link #createInstance } to obtain an instance of a
+ * transliterator given its ID. Valid IDs may be enumerated using
+ * <code>getAvailableIDs()</code>. Since transliterators are mutable,
+ * multiple calls to {@link #createInstance } with the same ID will
+ * return distinct objects.
+ *
+ * <p>In addition to the system transliterators registered at startup,
+ * user transliterators may be registered by calling
+ * <code>registerInstance()</code> at run time. A registered instance
+ * acts a template; future calls to {@link #createInstance } with the ID
+ * of the registered object return clones of that object. Thus any
+ * object passed to <tt>registerInstance()</tt> must implement
+ * <tt>clone()</tt> propertly. To register a transliterator subclass
+ * without instantiating it (until it is needed), users may call
+ * {@link #registerFactory }. In this case, the objects are
+ * instantiated by invoking the zero-argument public constructor of
+ * the class.
+ *
+ * <p><b>Subclassing</b>
+ *
+ * Subclasses must implement the abstract method
+ * <code>handleTransliterate()</code>. <p>Subclasses should override
+ * the <code>transliterate()</code> method taking a
+ * <code>Replaceable</code> and the <code>transliterate()</code>
+ * method taking a <code>String</code> and <code>StringBuffer</code>
+ * if the performance of these methods can be improved over the
+ * performance obtained by the default implementations in this class.

- * \brief C API: Bidi algorithm
- *
- * <h2>Bidi algorithm for ICU</h2>
- *
- * This is an implementation of the Unicode Bidirectional algorithm.
- * The algorithm is defined in the
- * <a href="http://www.unicode.org/unicode/reports/tr9/">Unicode Standard Annex #9</a>,
- * version 13, also described in The Unicode Standard, Version 4.0 .<p>
- *
- * Note: Libraries that perform a bidirectional algorithm and
- * reorder strings accordingly are sometimes called "Storage Layout Engines".
- * ICU's Bidi and shaping (u_shapeArabic()) APIs can be used at the core of such
- * "Storage Layout Engines".
- *
- * <h3>General remarks about the API:</h3>
- *
- * In functions with an error code parameter,
- * the <code>pErrorCode</code> pointer must be valid
- * and the value that it points to must not indicate a failure before
- * the function call. Otherwise, the function returns immediately.
- * After the function call, the value indicates success or failure.<p>
- *
- * The "limit" of a sequence of characters is the position just after their
- * last character, i.e., one more than that position.<p>
- *
- * Some of the API functions provide access to "runs".
- * Such a "run" is defined as a sequence of characters
- * that are at the same embedding level
- * after performing the Bidi algorithm.<p>
- *
- * @author Markus W. Scherer
- * @version 1.0

- * <h4> Sample code for the ICU Bidi API </h4>
- *
- * <h5>Rendering a paragraph with the ICU Bidi API</h5>
- *
- * This is (hypothetical) sample code that illustrates
- * how the ICU Bidi API could be used to render a paragraph of text.
- * Rendering code depends highly on the graphics system,
- * therefore this sample code must make a lot of assumptions,
- * which may or may not match any existing graphics system's properties.
- *
- * <p>The basic assumptions are:</p>
- * <ul>
- * <li>Rendering is done from left to right on a horizontal line.</li>
- * <li>A run of single-style, unidirectional text can be rendered at once.</li>
- * <li>Such a run of text is passed to the graphics system with
- * characters (code units) in logical order.</li>
- * <li>The line-breaking algorithm is very complicated
- * and Locale-dependent -
- * and therefore its implementation omitted from this sample code.</li>
- * </ul>

- *

- *
- * <p>In other cases, it may be desirable to emulate some variant of the
- * Logical to Visual algorithm (e.g. one used in MS Windows), or perform a
- * Logical to Logical transformation.</p>
- *
- * <ul>
- * <li>When the reordering mode is set to <code>#UBIDI_REORDER_DEFAULT</code>,
- * the standard Bidi Logical to Visual algorithm is applied.</li>
- *
- * <li>When the reordering mode is set to
- * <code>#UBIDI_REORDER_NUMBERS_SPECIAL</code>,
- * the algorithm used to perform Bidi transformations when calling
- * <code>ubidi_setPara</code> should approximate the algorithm used in
- * Microsoft Windows XP rather than strictly conform to the Unicode Bidi
- * algorithm.
- * <br>
- * The differences between the basic algorithm and the algorithm addressed
- * by this option are as follows:
- * <ul>
- * <li>Within text at an even embedding level, the sequence "123AB"
- * (where AB represent R or AL letters) is transformed to "123BA" by the
- * Unicode algorithm and to "BA123" by the Windows algorithm.</li>
- * <li>Arabic-Indic numbers (AN) are handled by the Windows algorithm just
- * like regular numbers (EN).</li>
- * </ul></li>
- *
- * <li>When the reordering mode is set to
- * <code>#UBIDI_REORDER_GROUP_NUMBERS_WITH_R</code>,
- * numbers located between LTR text and RTL text are associated with the RTL
- * text. For instance, an LTR paragraph with content "abc 123 DEF" (where
- * upper case letters represent RTL characters) will be transformed to
- * "abc FED 123" (and not "abc 123 FED"), "DEF 123 abc" will be transformed
- * to "123 FED abc" and "123 FED abc" will be transformed to "DEF 123 abc".
- * This makes the algorithm reversible and makes it useful when round trip
- * (from visual to logical and back to visual) must be achieved without
- * adding LRM characters. However, this is a variation from the standard
- * Unicode Bidi algorithm.<br>
- * The source text should not contain Bidi control characters other than LRM
- * or RLM.</li>
- *
- * <li>When the reordering mode is set to
- * <code>#UBIDI_REORDER_RUNS_ONLY</code>,
- * a "Logical to Logical" transformation must be performed:
- * <ul>
- * <li>If the default text level of the source text (argument <code>paraLevel</code>
- * in <code>ubidi_setPara</code>) is even, the source text will be handled as
- * LTR logical text and will be transformed to the RTL logical text which has
- * the same LTR visual display.</li>
- * <li>If the default level of the source text is odd, the source text
- * will be handled as RTL logical text and will be transformed to the
- * LTR logical text which has the same LTR visual display.</li>
- * </ul>
- * This mode may be needed when logical text which is basically Arabic or
- * Hebrew, with possible included numbers or phrases in English, has to be
- * displayed as if it had an even embedding level (this can happen if the
- * displaying application treats all text as if it was basically LTR).
- * <br>
- * This mode may also be needed in the reverse case, when logical text which is
- * basically English, with possible included phrases in Arabic or Hebrew, has to
- * be displayed as if it had an odd embedding level.
- * <br>
- * Both cases could be handled by adding LRE or RLE at the head of the text,
- * if the display subsystem supports these formatting controls. If it does not,
- * the problem may be handled by transforming the source text in this mode
- * before displaying it, so that it will be displayed properly.<br>
- * The source text should not contain Bidi control characters other than LRM
- * or RLM.</li>
- *
- * <li>When the reordering mode is set to

- * is applied.

- * may need to be surrounded with LRM characters when they are written in
- * reordered sequence (the option <code>#UBIDI_INSERT_LRM_FOR_NUMERIC</code> can
- * be used with function <code>ubidi_writeReordered</code> to this end. This
- * mode is equivalent to calling <code>ubidi_setInverse()</code> with
- * argument <code>isInverse</code> set to <code>TRUE</code>.</li>
- *
- * <li>When the reordering mode is set to
- * <code>#UBIDI_REORDER_INVERSE_LIKE_DIRECT</code>, the "direct" Logical to Visual
- * Bidi algorithm is used as an approximation of an "inverse Bidi" algorithm.
- * This mode is similar to mode <code>#UBIDI_REORDER_INVERSE_NUMBERS_AS_L</code>
- * but is closer to the regular Bidi algorithm.
- * <br>
- * For example, an LTR paragraph with the content "FED 123 456 CBA" (where
- * upper case represents RTL characters) will be transformed to
- * "ABC 456 123 DEF", as opposed to "DEF 123 456 ABC"
- * with mode <code>UBIDI_REORDER_INVERSE_NUMBERS_AS_L</code>.<br>
- * When used in conjunction with option
- * <code>#UBIDI_OPTION_INSERT_MARKS</code>, this mode generally
- * adds Bidi marks to the output significantly more sparingly than mode
- * <code>#UBIDI_REORDER_INVERSE_NUMBERS_AS_L</code> with option
- * <code>#UBIDI_INSERT_LRM_FOR_NUMERIC</code> in calls to
- * <code>ubidi_writeReordered</code>.</li>
- *
- * <li>When the reordering mode is set to
- * <code>#UBIDI_REORDER_INVERSE_FOR_NUMBERS_SPECIAL</code>, the Logical to Visual
- * Bidi algorithm used in Windows XP is used as an approximation of an
- * "inverse Bidi" algorithm.
- * <br>
- * For example, an LTR paragraph with the content "abc FED123" (where
- * upper case represents RTL characters) will be transformed to
- * "abc 123DEF.</li>
- * </ul>
- *
- * <p>In all the reordering modes specifying an "inverse Bidi" algorithm
- * (i.e. those with a name starting with <code>UBIDI_REORDER_INVERSE</code>),
- * output runs should be retrieved using
- * <code>ubidi_getVisualRun()</code>, and the output text with

- * This function takes a piece of plain text containing one or more paragraphs,

- * text and computes the left-right-directionality of each character.<p>
- *
- * If the entire text is all of the same directionality, then
- * the function may not perform all the steps described by the algorithm,
- * i.e., some levels may not be the same as if all steps were performed.
- * This is not relevant for unidirectional text.<br>
- * For example, in pure LTR text with numbers the numbers would get
- * a resolved level of 2 higher than the surrounding text according to
- * the algorithm. This implementation may set all resolved levels to
- * the same value in such a case.<p>
- *
- * The text can be composed of multiple paragraphs. Occurrence of a block
- * separator in the text terminates a paragraph, and whatever comes next starts
- * a new paragraph. The exception to this rule is when a Carriage Return (CR)
- * is followed by a Line Feed (LF). Both CR and LF are block separators, but
- * in that case, the pair of characters is considered as terminating the
- * preceding paragraph, and a new paragraph will be started by a character
- * coming after the LF.

- *
- * @param length is the length of the text; if <code>length==-1</code> then

- *
- * @param paraLevel specifies the default level for the text;

- * If the function shall determine the paragraph level from the text,
- * then <code>paraLevel</code> can be set to
- * either <code>#UBIDI_DEFAULT_LTR</code>
- * or <code>#UBIDI_DEFAULT_RTL</code>; if the text contains multiple
- * paragraphs, the paragraph level shall be determined separately for
- * each paragraph; if a paragraph does not include any strongly typed
- * character, then the desired default is used (0 for LTR or 1 for RTL).
- * Any other value between 0 and <code>#UBIDI_MAX_EXPLICIT_LEVEL</code>
- * is also valid, with odd levels indicating RTL.
- *
- * @param embeddingLevels (in) may be used to preset the embedding and override levels,

+/**
+ *\file
+ * \brief C API: Bidi algorithm
+ *
+ * <h2>Bidi algorithm for ICU</h2>
+ *
+ * This is an implementation of the Unicode Bidirectional algorithm.
+ * The algorithm is defined in the
+ * <a href="http://www.unicode.org/unicode/reports/tr9/">Unicode Standard Annex #9</a>,
+ * version 13, also described in The Unicode Standard, Version 4.0 .<p>
+ *
+ * Note: Libraries that perform a bidirectional algorithm and
+ * reorder strings accordingly are sometimes called "Storage Layout Engines".
+ * ICU's Bidi and shaping (u_shapeArabic()) APIs can be used at the core of such
+ * "Storage Layout Engines".
+ *
+ * <h3>General remarks about the API:</h3>
+ *
+ * In functions with an error code parameter,
+ * the <code>pErrorCode</code> pointer must be valid
+ * and the value that it points to must not indicate a failure before
+ * the function call. Otherwise, the function returns immediately.
+ * After the function call, the value indicates success or failure.<p>
+ *
+ * The "limit" of a sequence of characters is the position just after their
+ * last character, i.e., one more than that position.<p>
+ *
+ * Some of the API functions provide access to "runs".
+ * Such a "run" is defined as a sequence of characters
+ * that are at the same embedding level
+ * after performing the Bidi algorithm.<p>
+ *
+ * @author Markus W. Scherer
+ * @version 1.0

+ *
+ * <h4> Sample code for the ICU Bidi API </h4>
+ *
+ * <h5>Rendering a paragraph with the ICU Bidi API</h5>
+ *
+ * This is (hypothetical) sample code that illustrates
+ * how the ICU Bidi API could be used to render a paragraph of text.
+ * Rendering code depends highly on the graphics system,
+ * therefore this sample code must make a lot of assumptions,
+ * which may or may not match any existing graphics system's properties.
+ *
+ * <p>The basic assumptions are:</p>
+ * <ul>
+ * <li>Rendering is done from left to right on a horizontal line.</li>
+ * <li>A run of single-style, unidirectional text can be rendered at once.</li>
+ * <li>Such a run of text is passed to the graphics system with
+ * characters (code units) in logical order.</li>
+ * <li>The line-breaking algorithm is very complicated
+ * and Locale-dependent -
+ * and therefore its implementation omitted from this sample code.</li>
+ * </ul>

+ *
+ * <p>In other cases, it may be desirable to emulate some variant of the
+ * Logical to Visual algorithm (e.g. one used in MS Windows), or perform a
+ * Logical to Logical transformation.</p>
+ *
+ * <ul>
+ * <li>When the reordering mode is set to <code>#UBIDI_REORDER_DEFAULT</code>,
+ * the standard Bidi Logical to Visual algorithm is applied.</li>
+ *
+ * <li>When the reordering mode is set to
+ * <code>#UBIDI_REORDER_NUMBERS_SPECIAL</code>,
+ * the algorithm used to perform Bidi transformations when calling
+ * <code>ubidi_setPara</code> should approximate the algorithm used in
+ * Microsoft Windows XP rather than strictly conform to the Unicode Bidi
+ * algorithm.
+ * <br>
+ * The differences between the basic algorithm and the algorithm addressed
+ * by this option are as follows:
+ * <ul>
+ * <li>Within text at an even embedding level, the sequence "123AB"
+ * (where AB represent R or AL letters) is transformed to "123BA" by the
+ * Unicode algorithm and to "BA123" by the Windows algorithm.</li>
+ * <li>Arabic-Indic numbers (AN) are handled by the Windows algorithm just
+ * like regular numbers (EN).</li>
+ * </ul></li>
+ *
+ * <li>When the reordering mode is set to
+ * <code>#UBIDI_REORDER_GROUP_NUMBERS_WITH_R</code>,
+ * numbers located between LTR text and RTL text are associated with the RTL
+ * text. For instance, an LTR paragraph with content "abc 123 DEF" (where
+ * upper case letters represent RTL characters) will be transformed to
+ * "abc FED 123" (and not "abc 123 FED"), "DEF 123 abc" will be transformed
+ * to "123 FED abc" and "123 FED abc" will be transformed to "DEF 123 abc".
+ * This makes the algorithm reversible and makes it useful when round trip
+ * (from visual to logical and back to visual) must be achieved without
+ * adding LRM characters. However, this is a variation from the standard
+ * Unicode Bidi algorithm.<br>
+ * The source text should not contain Bidi control characters other than LRM
+ * or RLM.</li>
+ *
+ * <li>When the reordering mode is set to
+ * <code>#UBIDI_REORDER_RUNS_ONLY</code>,
+ * a "Logical to Logical" transformation must be performed:
+ * <ul>
+ * <li>If the default text level of the source text (argument <code>paraLevel</code>
+ * in <code>ubidi_setPara</code>) is even, the source text will be handled as
+ * LTR logical text and will be transformed to the RTL logical text which has
+ * the same LTR visual display.</li>
+ * <li>If the default level of the source text is odd, the source text
+ * will be handled as RTL logical text and will be transformed to the
+ * LTR logical text which has the same LTR visual display.</li>
+ * </ul>
+ * This mode may be needed when logical text which is basically Arabic or
+ * Hebrew, with possible included numbers or phrases in English, has to be
+ * displayed as if it had an even embedding level (this can happen if the
+ * displaying application treats all text as if it was basically LTR).
+ * <br>
+ * This mode may also be needed in the reverse case, when logical text which is
+ * basically English, with possible included phrases in Arabic or Hebrew, has to
+ * be displayed as if it had an odd embedding level.
+ * <br>
+ * Both cases could be handled by adding LRE or RLE at the head of the text,
+ * if the display subsystem supports these formatting controls. If it does not,
+ * the problem may be handled by transforming the source text in this mode
+ * before displaying it, so that it will be displayed properly.<br>
+ * The source text should not contain Bidi control characters other than LRM
+ * or RLM.</li>
+ *
+ * <li>When the reordering mode is set to

+ * is applied.
+ * Runs of text with numeric characters will be treated like LTR letters and

+ * be used with function <code>ubidi_writeReordered</code> to this end. This

+ *
+ * <li>When the reordering mode is set to
+ * <code>#UBIDI_REORDER_INVERSE_LIKE_DIRECT</code>, the "direct" Logical to Visual
+ * Bidi algorithm is used as an approximation of an "inverse Bidi" algorithm.
+ * This mode is similar to mode <code>#UBIDI_REORDER_INVERSE_NUMBERS_AS_L</code>
+ * but is closer to the regular Bidi algorithm.
+ * <br>
+ * For example, an LTR paragraph with the content "FED 123 456 CBA" (where
+ * upper case represents RTL characters) will be transformed to
+ * "ABC 456 123 DEF", as opposed to "DEF 123 456 ABC"
+ * with mode <code>UBIDI_REORDER_INVERSE_NUMBERS_AS_L</code>.<br>
+ * When used in conjunction with option
+ * <code>#UBIDI_OPTION_INSERT_MARKS</code>, this mode generally
+ * adds Bidi marks to the output significantly more sparingly than mode
+ * <code>#UBIDI_REORDER_INVERSE_NUMBERS_AS_L</code> with option
+ * <code>#UBIDI_INSERT_LRM_FOR_NUMERIC</code> in calls to
+ * <code>ubidi_writeReordered</code>.</li>
+ *
+ * <li>When the reordering mode is set to
+ * <code>#UBIDI_REORDER_INVERSE_FOR_NUMBERS_SPECIAL</code>, the Logical to Visual

+ * "inverse Bidi" algorithm.
+ * <br>
+ * For example, an LTR paragraph with the content "abc FED123" (where

+ * <a href="http://www.unicode.org/unicode/reports/tr9/">Unicode Standard Anned #9</a>,
+ * version 13,
+ * also described in The Unicode Standard, Version 4.0 .<p>
+ *
+ * This function takes a piece of plain text containing one or more paragraphs,
+ * with or without externally specified embedding levels from <i>styled</i>
+ * text and computes the left-right-directionality of each character.<p>
+ *
+ * If the entire text is all of the same directionality, then
+ * the function may not perform all the steps described by the algorithm,
+ * i.e., some levels may not be the same as if all steps were performed.
+ * This is not relevant for unidirectional text.<br>
+ * For example, in pure LTR text with numbers the numbers would get
+ * a resolved level of 2 higher than the surrounding text according to
+ * the algorithm. This implementation may set all resolved levels to
+ * the same value in such a case.<p>
+ *
+ * The text can be composed of multiple paragraphs. Occurrence of a block
+ * separator in the text terminates a paragraph, and whatever comes next starts
+ * a new paragraph. The exception to this rule is when a Carriage Return (CR)
+ * is followed by a Line Feed (LF). Both CR and LF are block separators, but
+ * in that case, the pair of characters is considered as terminating the
+ * preceding paragraph, and a new paragraph will be started by a character
+ * coming after the LF.
+ *
+ * @param pBiDi A <code>UBiDi</code> object allocated with <code>ubidi_open()</code>
+ * which will be set to contain the reordering information,
+ * especially the resolved levels for all the characters in <code>text</code>.
+ *
+ * @param text is a pointer to the text that the Bidi algorithm will be performed on.
+ * This pointer is stored in the UBiDi object and can be retrieved
+ * with <code>ubidi_getText()</code>.<br>
+ * <strong>Note:</strong> the text must be (at least) <code>length</code> long.
+ *
+ * @param length is the length of the text; if <code>length==-1</code> then
+ * the text must be zero-terminated.
+ *
+ * @param paraLevel specifies the default level for the text;
+ * it is typically 0 (LTR) or 1 (RTL).
+ * If the function shall determine the paragraph level from the text,
+ * then <code>paraLevel</code> can be set to
+ * either <code>#UBIDI_DEFAULT_LTR</code>
+ * or <code>#UBIDI_DEFAULT_RTL</code>; if the text contains multiple
+ * paragraphs, the paragraph level shall be determined separately for
+ * each paragraph; if a paragraph does not include any strongly typed
+ * character, then the desired default is used (0 for LTR or 1 for RTL).
+ * Any other value between 0 and <code>#UBIDI_MAX_EXPLICIT_LEVEL</code>
+ * is also valid, with odd levels indicating RTL.
+ *
+ * @param embeddingLevels (in) may be used to preset the embedding and override levels,
+ * ignoring characters like LRE and PDF in the text.
+ * A level overrides the directional property of its corresponding
+ * (same index) character if the level has the
+ * <code>#UBIDI_LEVEL_OVERRIDE</code> bit set.<br><br>
+ * Except for that bit, it must be
+ * <code>paraLevel<=embeddingLevels[]<=UBIDI_MAX_EXPLICIT_LEVEL</code>,
+ * with one exception: a level of zero may be specified for a paragraph
+ * separator even if <code>paraLevel>0</code> when multiple paragraphs
+ * are submitted in the same call to <code>ubidi_setPara()</code>.<br><br>
+ * <strong>Caution: </strong>A copy of this pointer, not of the levels,
+ * will be stored in the <code>UBiDi</code> object;
+ * the <code>embeddingLevels</code> array must not be
+ * deallocated before the <code>UBiDi</code> structure is destroyed or reused,
+ * and the <code>embeddingLevels</code>
+ * should not be modified to avoid unexpected results on subsequent Bidi operations.
+ * However, the <code>ubidi_setPara()</code> and
+ * <code>ubidi_setLine()</code> functions may modify some or all of the levels.<br><br>
+ * After the <code>UBiDi</code> object is reused or destroyed, the caller

- * \brief C API: BreakIterator
- *
- * <h2> BreakIterator C API </h2>
- *
- * The BreakIterator C API defines methods for finding the location
- * of boundaries in text. Pointer to a UBreakIterator maintain a
- * current position and scan over text returning the index of characters
- * where boundaries occur.
- * <p>
- * Line boundary analysis determines where a text string can be broken
- * when line-wrapping. The mechanism correctly handles punctuation and
- * hyphenated words.
- * <p>
- * Sentence boundary analysis allows selection with correct
- * interpretation of periods within numbers and abbreviations, and
- * trailing punctuation marks such as quotation marks and parentheses.
- * <p>
- * Word boundary analysis is used by search and replace functions, as
- * well as within text editing applications that allow the user to
- * select words with a double click. Word selection provides correct
- * interpretation of punctuation marks within and following
- * words. Characters that are not part of a word, such as symbols or
- * punctuation marks, have word-breaks on both sides.
- * <p>
- * Character boundary analysis allows users to interact with
- * characters as they expect to, for example, when moving the cursor
- * through a text string. Character boundary analysis provides correct
- * navigation of through character strings, regardless of how the
- * character is stored. For example, an accented character might be
- * stored as a base character and a diacritical mark. What users
- * consider to be a character can differ between languages.
- * <p>
- * Title boundary analysis locates all positions,
- * typically starts of words, that should be set to Title Case
- * when title casing the text.
- * <p>
- * The text boundary positions are found according to the rules
- * described in Unicode Standard Annex #29, Text Boundaries, and
- * Unicode Standard Annex #14, Line Breaking Properties. These
- * are available at http://www.unicode.org/reports/tr14/ and
- * http://www.unicode.org/reports/tr29/.
- * <p>
- * In addition to the plain C API defined in this header file, an
- * object oriented C++ API with equivalent functionality is defined in the
- * file brkiter.h.
- * <p>
- * Code snippits illustrating the use of the Break Iterator APIs
- * are available in the ICU User Guide,
- * http://icu-project.org/userguide/boundaryAnalysis.html
- * and in the sample program icu/source/samples/break/break.cpp"

+ * \brief C API: BreakIterator
+ *
+ * <h2> BreakIterator C API </h2>
+ *
+ * The BreakIterator C API defines methods for finding the location
+ * of boundaries in text. Pointer to a UBreakIterator maintain a
+ * current position and scan over text returning the index of characters
+ * where boundaries occur.
+ * <p>
+ * Line boundary analysis determines where a text string can be broken
+ * when line-wrapping. The mechanism correctly handles punctuation and
+ * hyphenated words.
+ * <p>
+ * Sentence boundary analysis allows selection with correct
+ * interpretation of periods within numbers and abbreviations, and
+ * trailing punctuation marks such as quotation marks and parentheses.
+ * <p>
+ * Word boundary analysis is used by search and replace functions, as
+ * well as within text editing applications that allow the user to
+ * select words with a double click. Word selection provides correct
+ * interpretation of punctuation marks within and following
+ * words. Characters that are not part of a word, such as symbols or
+ * punctuation marks, have word-breaks on both sides.
+ * <p>
+ * Character boundary analysis allows users to interact with
+ * characters as they expect to, for example, when moving the cursor
+ * through a text string. Character boundary analysis provides correct
+ * navigation of through character strings, regardless of how the
+ * character is stored. For example, an accented character might be
+ * stored as a base character and a diacritical mark. What users
+ * consider to be a character can differ between languages.
+ * <p>
+ * Title boundary analysis locates all positions,
+ * typically starts of words, that should be set to Title Case
+ * when title casing the text.
+ * <p>
+ * The text boundary positions are found according to the rules
+ * described in Unicode Standard Annex #29, Text Boundaries, and
+ * Unicode Standard Annex #14, Line Breaking Properties. These
+ * are available at http://www.unicode.org/reports/tr14/ and
+ * http://www.unicode.org/reports/tr29/.
+ * <p>
+ * In addition to the plain C API defined in this header file, an
+ * object oriented C++ API with equivalent functionality is defined in the
+ * file brkiter.h.
+ * <p>
+ * Code snippits illustrating the use of the Break Iterator APIs
+ * are available in the ICU User Guide,
+ * http://icu-project.org/userguide/boundaryAnalysis.html
+ * and in the sample program icu/source/samples/break/break.cpp"

- * \file
- * \brief C API: Calendar
- *
- * <h2>Calendar C API</h2>
- *
- * UCalendar C API is used for converting between a <code>UDate</code> object
- * and a set of integer fields such as <code>UCAL_YEAR</code>, <code>UCAL_MONTH</code>,
- * <code>UCAL_DAY</code>, <code>UCAL_HOUR</code>, and so on.
- * (A <code>UDate</code> object represents a specific instant in
- * time with millisecond precision. See UDate
- * for information about the <code>UDate</code> .)
- *
- * <p>
- * Types of <code>UCalendar</code> interpret a <code>UDate</code>
- * according to the rules of a specific calendar system. The U_STABLE
- * provides the enum UCalendarType with UCAL_TRADITIONAL and
- * UCAL_GREGORIAN.
- * <p>
- * Like other locale-sensitive C API, calendar API provides a
- * function, <code>ucal_open()</code>, which returns a pointer to
- * <code>UCalendar</code> whose time fields have been initialized
- * with the current date and time. We need to specify the type of
- * calendar to be opened and the timezoneId.
- * \htmlonly<blockquote>\endhtmlonly
- * <pre>
- * \code
- * UCalendar *caldef;
- * UChar *tzId;
- * UErrorCode status;
- * tzId=(UChar*)malloc(sizeof(UChar) * (strlen("PST") +1) );
- * u_uastrcpy(tzId, "PST");
- * caldef=ucal_open(tzID, u_strlen(tzID), NULL, UCAL_TRADITIONAL, &status);
- * \endcode
- * </pre>
- * \htmlonly</blockquote>\endhtmlonly
- *
- * <p>
- * A <code>UCalendar</code> object can produce all the time field values
- * needed to implement the date-time formatting for a particular language
- * and calendar style (for example, Japanese-Gregorian, Japanese-Traditional).
- *
- * <p>
- * When computing a <code>UDate</code> from time fields, two special circumstances
- * may arise: there may be insufficient information to compute the
- * <code>UDate</code> (such as only year and month but no day in the month),
- * or there may be inconsistent information (such as "Tuesday, July 15, 1996"
- * -- July 15, 1996 is actually a Monday).
- *
- * <p>
- * <strong>Insufficient information.</strong> The calendar will use default
- * information to specify the missing fields. This may vary by calendar; for
- * the Gregorian calendar, the default for a field is the same as that of the
- * start of the epoch: i.e., UCAL_YEAR = 1970, UCAL_MONTH = JANUARY, UCAL_DATE = 1, etc.
- *
- * <p>
- * <strong>Inconsistent information.</strong> If fields conflict, the calendar
- * will give preference to fields set more recently. For example, when
- * determining the day, the calendar will look for one of the following
- * combinations of fields. The most recent combination, as determined by the
- * most recently set single field, will be used.
- *
- * \htmlonly<blockquote>\endhtmlonly
- * <pre>
- * \code
- * UCAL_MONTH + UCAL_DAY_OF_MONTH
- * UCAL_MONTH + UCAL_WEEK_OF_MONTH + UCAL_DAY_OF_WEEK
- * UCAL_MONTH + UCAL_DAY_OF_WEEK_IN_MONTH + UCAL_DAY_OF_WEEK
- * UCAL_DAY_OF_YEAR
- * UCAL_DAY_OF_WEEK + UCAL_WEEK_OF_YEAR
- * \endcode
- * </pre>
- * \htmlonly</blockquote>\endhtmlonly
- *
- * For the time of day:
- *
- * \htmlonly<blockquote>\endhtmlonly
- * <pre>
- * \code
- * UCAL_HOUR_OF_DAY
- * UCAL_AM_PM + UCAL_HOUR
- * \endcode
- * </pre>
- * \htmlonly</blockquote>\endhtmlonly
- *
- * <p>
- * <strong>Note:</strong> for some non-Gregorian calendars, different
- * fields may be necessary for complete disambiguation. For example, a full
- * specification of the historial Arabic astronomical calendar requires year,
- * month, day-of-month <em>and</em> day-of-week in some cases.
- *
- * <p>
- * <strong>Note:</strong> There are certain possible ambiguities in
- * interpretation of certain singular times, which are resolved in the
- * following ways:
- * <ol>
- * <li> 24:00:00 "belongs" to the following day. That is,
- * 23:59 on Dec 31, 1969 < 24:00 on Jan 1, 1970 < 24:01:00 on Jan 1, 1970
- *
- * <li> Although historically not precise, midnight also belongs to "am",
- * and noon belongs to "pm", so on the same day,
- * 12:00 am (midnight) < 12:01 am, and 12:00 pm (noon) < 12:01 pm
- * </ol>
- *
- * <p>
- * The date or time format strings are not part of the definition of a
- * calendar, as those must be modifiable or overridable by the user at
- * runtime. Use {@link DateFormat}
- * to format dates.
- *
- * <p>
- * <code>Calendar</code> provides an API for field "rolling", where fields
- * can be incremented or decremented, but wrap around. For example, rolling the
- * month up in the date <code>December 12, <b>1996</b></code> results in
- * <code>January 12, <b>1996</b></code>.
- *
- * <p>
- * <code>Calendar</code> also provides a date arithmetic function for
- * adding the specified (signed) amount of time to a particular time field.
- * For example, subtracting 5 days from the date <code>September 12, 1996</code>
- * results in <code>September 7, 1996</code>.

+ * \brief C API: Calendar
+ *
+ * <h2>Calendar C API</h2>
+ *
+ * UCalendar C API is used for converting between a <code>UDate</code> object
+ * and a set of integer fields such as <code>UCAL_YEAR</code>, <code>UCAL_MONTH</code>,
+ * <code>UCAL_DAY</code>, <code>UCAL_HOUR</code>, and so on.
+ * (A <code>UDate</code> object represents a specific instant in
+ * time with millisecond precision. See UDate
+ * for information about the <code>UDate</code> .)
+ *
+ * <p>
+ * Types of <code>UCalendar</code> interpret a <code>UDate</code>
+ * according to the rules of a specific calendar system. The U_STABLE
+ * provides the enum UCalendarType with UCAL_TRADITIONAL and
+ * UCAL_GREGORIAN.
+ * <p>
+ * Like other locale-sensitive C API, calendar API provides a
+ * function, <code>ucal_open()</code>, which returns a pointer to
+ * <code>UCalendar</code> whose time fields have been initialized
+ * with the current date and time. We need to specify the type of
+ * calendar to be opened and the timezoneId.
+ * \htmlonly<blockquote>\endhtmlonly
+ * <pre>
+ * \code
+ * UCalendar *caldef;
+ * UChar *tzId;
+ * UErrorCode status;
+ * tzId=(UChar*)malloc(sizeof(UChar) * (strlen("PST") +1) );
+ * u_uastrcpy(tzId, "PST");
+ * caldef=ucal_open(tzID, u_strlen(tzID), NULL, UCAL_TRADITIONAL, &status);
+ * \endcode
+ * </pre>
+ * \htmlonly</blockquote>\endhtmlonly
+ *
+ * <p>
+ * A <code>UCalendar</code> object can produce all the time field values
+ * needed to implement the date-time formatting for a particular language
+ * and calendar style (for example, Japanese-Gregorian, Japanese-Traditional).
+ *
+ * <p>
+ * When computing a <code>UDate</code> from time fields, two special circumstances
+ * may arise: there may be insufficient information to compute the
+ * <code>UDate</code> (such as only year and month but no day in the month),
+ * or there may be inconsistent information (such as "Tuesday, July 15, 1996"
+ * -- July 15, 1996 is actually a Monday).
+ *
+ * <p>
+ * <strong>Insufficient information.</strong> The calendar will use default
+ * information to specify the missing fields. This may vary by calendar; for
+ * the Gregorian calendar, the default for a field is the same as that of the
+ * start of the epoch: i.e., UCAL_YEAR = 1970, UCAL_MONTH = JANUARY, UCAL_DATE = 1, etc.
+ *
+ * <p>
+ * <strong>Inconsistent information.</strong> If fields conflict, the calendar
+ * will give preference to fields set more recently. For example, when
+ * determining the day, the calendar will look for one of the following
+ * combinations of fields. The most recent combination, as determined by the
+ * most recently set single field, will be used.
+ *

+ *
+ * <p>
+ * <strong>Note:</strong> for some non-Gregorian calendars, different
+ * fields may be necessary for complete disambiguation. For example, a full
+ * specification of the historial Arabic astronomical calendar requires year,
+ * month, day-of-month <em>and</em> day-of-week in some cases.
+ *
+ * <p>
+ * <strong>Note:</strong> There are certain possible ambiguities in
+ * interpretation of certain singular times, which are resolved in the
+ * following ways:
+ * <ol>
+ * <li> 24:00:00 "belongs" to the following day. That is,
+ * 23:59 on Dec 31, 1969 < 24:00 on Jan 1, 1970 < 24:01:00 on Jan 1, 1970
+ *
+ * <li> Although historically not precise, midnight also belongs to "am",
+ * and noon belongs to "pm", so on the same day,
+ * 12:00 am (midnight) < 12:01 am, and 12:00 pm (noon) < 12:01 pm
+ * </ol>
+ *
+ * <p>
+ * The date or time format strings are not part of the definition of a
+ * calendar, as those must be modifiable or overridable by the user at
+ * runtime. Use {@link DateFormat}
+ * to format dates.
+ *
+ * <p>
+ * <code>Calendar</code> provides an API for field "rolling", where fields
+ * can be incremented or decremented, but wrap around. For example, rolling the
+ * month up in the date <code>December 12, <b>1996</b></code> results in
+ * <code>January 12, <b>1996</b></code>.
+ *
+ * <p>
+ * <code>Calendar</code> also provides a date arithmetic function for
+ * adding the specified (signed) amount of time to a particular time field.
+ * For example, subtracting 5 days from the date <code>September 12, 1996</code>
+ * results in <code>September 7, 1996</code>.

- * \file
- * \brief C API: Message Catalog Wrappers
- *
- * This C API provides look-alike functions that deliberately resemble
- * the POSIX catopen, catclose, and catgets functions. The underlying
- * implementation is in terms of ICU resource bundles, rather than
- * POSIX message catalogs.
- *
- * The ICU resource bundles obey standard ICU inheritance policies.
- * To facilitate this, sets and messages are flattened into one tier.
- * This is done by creating resource bundle keys of the form
- * <set_num>%<msg_num> where set_num is the set number and msg_num is
- * the message number, formatted as decimal strings.
- *
- * Example: Consider a message catalog containing two sets:
- *
- * Set 1: Message 4 = "Good morning."
- * Message 5 = "Good afternoon."
- * Message 7 = "Good evening."
- * Message 8 = "Good night."
- * Set 4: Message 14 = "Please "
- * Message 19 = "Thank you."
- * Message 20 = "Sincerely,"
- *
- * The ICU resource bundle source file would, assuming it is named
- * "greet.txt", would look like this:
- *
- * greet
- * {
- * 1%4 { "Good morning." }
- * 1%5 { "Good afternoon." }
- * 1%7 { "Good evening." }
- * 1%8 { "Good night." }
- *
- * 4%14 { "Please " }
- * 4%19 { "Thank you." }
- * 4%20 { "Sincerely," }
- * }
- *
- * The catgets function is commonly used in combination with functions
- * like printf and strftime. ICU components like message format can
- * be used instead, although they use a different format syntax.
- * There is an ICU package, icuio, that provides some of
- * the POSIX-style formatting API.

+/**
+ * \file
+ * \brief C API: Message Catalog Wrappers
+ *
+ * This C API provides look-alike functions that deliberately resemble
+ * the POSIX catopen, catclose, and catgets functions. The underlying
+ * implementation is in terms of ICU resource bundles, rather than
+ * POSIX message catalogs.
+ *
+ * The ICU resource bundles obey standard ICU inheritance policies.
+ * To facilitate this, sets and messages are flattened into one tier.
+ * This is done by creating resource bundle keys of the form
+ * <set_num>%<msg_num> where set_num is the set number and msg_num is
+ * the message number, formatted as decimal strings.
+ *
+ * Example: Consider a message catalog containing two sets:
+ *
+ * Set 1: Message 4 = "Good morning."
+ * Message 5 = "Good afternoon."
+ * Message 7 = "Good evening."
+ * Message 8 = "Good night."
+ * Set 4: Message 14 = "Please "
+ * Message 19 = "Thank you."
+ * Message 20 = "Sincerely,"
+ *
+ * The ICU resource bundle source file would, assuming it is named
+ * "greet.txt", would look like this:
+ *
+ * greet
+ * {
+ * 1%4 { "Good morning." }
+ * 1%5 { "Good afternoon." }
+ * 1%7 { "Good evening." }
+ * 1%8 { "Good night." }
+ *
+ * 4%14 { "Please " }
+ * 4%19 { "Thank you." }
+ * 4%20 { "Sincerely," }
+ * }
+ *
+ * The catgets function is commonly used in combination with functions
+ * like printf and strftime. ICU components like message format can
+ * be used instead, although they use a different format syntax.
+ * There is an ICU package, icuio, that provides some of
+ * the POSIX-style formatting API.

-/**
- * \file
- * \brief C API: Unicode Properties
- *
- * This C API provides low-level access to the Unicode Character Database.
- * In addition to raw property values, some convenience functions calculate
- * derived properties, for example for Java-style programming.
- *
- * Unicode assigns each code point (not just assigned character) values for
- * many properties.
- * Most of them are simple boolean flags, or constants from a small enumerated list.
- * For some properties, values are strings or other relatively more complex types.
- *
- * For more information see
- * "About the Unicode Character Database" (http://www.unicode.org/ucd/)
- * and the ICU User Guide chapter on Properties (http://icu-project.org/userguide/properties.html).
- *
- * Many functions are designed to match java.lang.Character functions.
- * See the individual function documentation,
- * and see the JDK 1.4 java.lang.Character documentation
- * at http://java.sun.com/j2se/1.4/docs/api/java/lang/Character.html
- *
- * There are also functions that provide easy migration from C/POSIX functions
- * like isblank(). Their use is generally discouraged because the C/POSIX
- * standards do not define their semantics beyond the ASCII range, which means
- * that different implementations exhibit very different behavior.
- * Instead, Unicode properties should be used directly.
- *
- * There are also only a few, broad C/POSIX character classes, and they tend
- * to be used for conflicting purposes. For example, the "isalpha()" class
- * is sometimes used to determine word boundaries, while a more sophisticated
- * approach would at least distinguish initial letters from continuation
- * characters (the latter including combining marks).
- * (In ICU, BreakIterator is the most sophisticated API for word boundaries.)
- * Another example: There is no "istitle()" class for titlecase characters.
- *
- * ICU 3.4 and later provides API access for all twelve C/POSIX character classes.
- * ICU implements them according to the Standard Recommendations in
- * Annex C: Compatibility Properties of UTS #18 Unicode Regular Expressions
- * (http://www.unicode.org/reports/tr18/#Compatibility_Properties).
- *
- * API access for C/POSIX character classes is as follows:
- * - alpha: u_isUAlphabetic(c) or u_hasBinaryProperty(c, UCHAR_ALPHABETIC)
- * - lower: u_isULowercase(c) or u_hasBinaryProperty(c, UCHAR_LOWERCASE)
- * - upper: u_isUUppercase(c) or u_hasBinaryProperty(c, UCHAR_UPPERCASE)
- * - punct: u_ispunct(c)
- * - digit: u_isdigit(c) or u_charType(c)==U_DECIMAL_DIGIT_NUMBER
- * - xdigit: u_isxdigit(c) or u_hasBinaryProperty(c, UCHAR_POSIX_XDIGIT)
- * - alnum: u_hasBinaryProperty(c, UCHAR_POSIX_ALNUM)
- * - space: u_isUWhiteSpace(c) or u_hasBinaryProperty(c, UCHAR_WHITE_SPACE)
- * - blank: u_isblank(c) or u_hasBinaryProperty(c, UCHAR_POSIX_BLANK)
- * - cntrl: u_charType(c)==U_CONTROL_CHAR
- * - graph: u_hasBinaryProperty(c, UCHAR_POSIX_GRAPH)
- * - print: u_hasBinaryProperty(c, UCHAR_POSIX_PRINT)
- *
- * Note: Some of the u_isxyz() functions in uchar.h predate, and do not match,
- * the Standard Recommendations in UTS #18. Instead, they match Java
- * functions according to their API documentation.
- *
- * \htmlonly
- * The C/POSIX character classes are also available in UnicodeSet patterns,
- * using patterns like [:graph:] or \p{graph}.
- * \endhtmlonly
- *
- * Note: There are several ICU whitespace functions.
- * Comparison:
- * - u_isUWhiteSpace=UCHAR_WHITE_SPACE: Unicode White_Space property;
- * most of general categories "Z" (separators) + most whitespace ISO controls
- * (including no-break spaces, but excluding IS1..IS4 and ZWSP)
- * - u_isWhitespace: Java isWhitespace; Z + whitespace ISO controls but excluding no-break spaces
- * - u_isJavaSpaceChar: Java isSpaceChar; just Z (including no-break spaces)
- * - u_isspace: Z + whitespace ISO controls (including no-break spaces)
- * - u_isblank: "horizontal spaces" = TAB + Zs - ZWSP

+/**
+ * \file
+ * \brief C API: Unicode Properties
+ *
+ * This C API provides low-level access to the Unicode Character Database.
+ * In addition to raw property values, some convenience functions calculate
+ * derived properties, for example for Java-style programming.
+ *
+ * Unicode assigns each code point (not just assigned character) values for
+ * many properties.
+ * Most of them are simple boolean flags, or constants from a small enumerated list.
+ * For some properties, values are strings or other relatively more complex types.
+ *
+ * For more information see
+ * "About the Unicode Character Database" (http://www.unicode.org/ucd/)
+ * and the ICU User Guide chapter on Properties (http://icu-project.org/userguide/properties.html).
+ *
+ * Many functions are designed to match java.lang.Character functions.
+ * See the individual function documentation,
+ * and see the JDK 1.4 java.lang.Character documentation
+ * at http://java.sun.com/j2se/1.4/docs/api/java/lang/Character.html
+ *
+ * There are also functions that provide easy migration from C/POSIX functions
+ * like isblank(). Their use is generally discouraged because the C/POSIX
+ * standards do not define their semantics beyond the ASCII range, which means
+ * that different implementations exhibit very different behavior.
+ * Instead, Unicode properties should be used directly.
+ *
+ * There are also only a few, broad C/POSIX character classes, and they tend
+ * to be used for conflicting purposes. For example, the "isalpha()" class
+ * is sometimes used to determine word boundaries, while a more sophisticated
+ * approach would at least distinguish initial letters from continuation
+ * characters (the latter including combining marks).
+ * (In ICU, BreakIterator is the most sophisticated API for word boundaries.)
+ * Another example: There is no "istitle()" class for titlecase characters.
+ *
+ * ICU 3.4 and later provides API access for all twelve C/POSIX character classes.
+ * ICU implements them according to the Standard Recommendations in
+ * Annex C: Compatibility Properties of UTS #18 Unicode Regular Expressions
+ * (http://www.unicode.org/reports/tr18/#Compatibility_Properties).
+ *
+ * API access for C/POSIX character classes is as follows:
+ * - alpha: u_isUAlphabetic(c) or u_hasBinaryProperty(c, UCHAR_ALPHABETIC)
+ * - lower: u_isULowercase(c) or u_hasBinaryProperty(c, UCHAR_LOWERCASE)
+ * - upper: u_isUUppercase(c) or u_hasBinaryProperty(c, UCHAR_UPPERCASE)
+ * - punct: u_ispunct(c)
+ * - digit: u_isdigit(c) or u_charType(c)==U_DECIMAL_DIGIT_NUMBER
+ * - xdigit: u_isxdigit(c) or u_hasBinaryProperty(c, UCHAR_POSIX_XDIGIT)
+ * - alnum: u_hasBinaryProperty(c, UCHAR_POSIX_ALNUM)
+ * - space: u_isUWhiteSpace(c) or u_hasBinaryProperty(c, UCHAR_WHITE_SPACE)
+ * - blank: u_isblank(c) or u_hasBinaryProperty(c, UCHAR_POSIX_BLANK)
+ * - cntrl: u_charType(c)==U_CONTROL_CHAR
+ * - graph: u_hasBinaryProperty(c, UCHAR_POSIX_GRAPH)
+ * - print: u_hasBinaryProperty(c, UCHAR_POSIX_PRINT)
+ *
+ * Note: Some of the u_isxyz() functions in uchar.h predate, and do not match,
+ * the Standard Recommendations in UTS #18. Instead, they match Java
+ * functions according to their API documentation.
+ *
+ * \htmlonly
+ * The C/POSIX character classes are also available in UnicodeSet patterns,
+ * using patterns like [:graph:] or \p{graph}.
+ * \endhtmlonly
+ *
+ * Note: There are several ICU whitespace functions.
+ * Comparison:
+ * - u_isUWhiteSpace=UCHAR_WHITE_SPACE: Unicode White_Space property;
+ * most of general categories "Z" (separators) + most whitespace ISO controls
+ * (including no-break spaces, but excluding IS1..IS4 and ZWSP)
+ * - u_isWhitespace: Java isWhitespace; Z + whitespace ISO controls but excluding no-break spaces
+ * - u_isJavaSpaceChar: Java isSpaceChar; just Z (including no-break spaces)
+ * - u_isspace: Z + whitespace ISO controls (including no-break spaces)

- * Initialize ICU. The description further below applies to ICU 2.6 to ICU 3.4.
- * Starting with ICU 3.4, u_init() needs not be called any more for
- * ensuring thread safety, but it can give an indication for whether ICU
- * can load its data. In ICU 3.4, it will try to load the converter alias table
- * (cnvalias.icu) and give an error code if that fails.
- * This may change in the future.
- * <p>
- * For ensuring the availability of necessary data, an application should

- * and check for error codes there.
- * <p>
- * Documentation for ICU 2.6 to ICU 3.4:
- * <p>
- * This function loads and initializes data items
- * that are required internally by various ICU functions. Use of this explicit
- * initialization is required in multi-threaded applications; in
- * single threaded apps, use is optional, but incurs little additional
- * cost, and is thus recommended.
- * <p>
- * In multi-threaded applications, u_init() should be called in the
- * main thread before starting additional threads, or, alternatively
- * it can be called in each individual thread once, before other ICU
- * functions are called in that thread. In this second scenario, the
- * application must guarantee that the first call to u_init() happen
- * without contention, in a single thread only.
- * <p>
- * If <code>u_setMemoryFunctions()</code> or
- * <code>u_setMutexFunctions</code> are needed (uncommon), they must be
- * called _before_ <code>u_init()</code>.
- * <p>
- * Extra, repeated, or otherwise unneeded calls to u_init() do no harm,
- * other than taking a small amount of time.
- *
- * @param status An ICU UErrorCode parameter. It must not be <code>NULL</code>.
- * An Error will be returned if some required part of ICU data can not
- * be loaded or initialized.
- * The function returns immediately if the input error code indicates a

-/**
- * Clean up the system resources, such as allocated memory or open files,
- * used in all ICU libraries. This will free/delete all memory owned by the
- * ICU libraries, and return them to their original load state. All open ICU
- * items (collators, resource bundles, converters, etc.) must be closed before
- * calling this function, otherwise ICU may not free its allocated memory
- * (e.g. close your converters and resource bundles before calling this
- * function). Generally, this function should be called once just before
- * an application exits. For applications that dynamically load and unload
- * the ICU libraries (relatively uncommon), u_cleanup() should be called
- * just before the library unload.
- * <p>
- * u_cleanup() also clears any ICU heap functions, mutex functions or
- * trace functions that may have been set for the process.
- * This has the effect of restoring ICU to its initial condition, before
- * any of these override functions were installed. Refer to
- * u_setMemoryFunctions(), u_setMutexFunctions and
- * utrace_setFunctions(). If ICU is to be reinitialized after after
- * calling u_cleanup(), these runtime override functions will need to
- * be set up again if they are still required.
- * <p>
- * u_cleanup() is not thread safe. All other threads should stop using ICU
- * before calling this function.
- * <p>
- * Any open ICU items will be left in an undefined state by u_cleanup(),
- * and any subsequent attempt to use such an item will give unpredictable
- * results.
- * <p>
- * After calling u_cleanup(), an application may continue to use ICU by
- * calling u_init(). An application must invoke u_init() first from one single
- * thread before allowing other threads call u_init(). All threads existing
- * at the time of the first thread's call to u_init() must also call
- * u_init() themselves before continuing with other ICU operations.
- * <p>
- * The use of u_cleanup() just before an application terminates is optional,
- * but it should be called only once for performance reasons. The primary
- * benefit is to eliminate reports of memory or resource leaks originating
- * in ICU code from the results generated by heap analysis tools.

+ * (e.g. close your converters and resource bundles before calling this

+ * This has the effect of restoring ICU to its initial condition, before
+ * any of these override functions were installed. Refer to

- * \file
- * \brief C API: Character conversion
- *
- * <h2>Character Conversion C API</h2>
- *
- * <p>This API is used to convert codepage or character encoded data to and
- * from UTF-16. You can open a converter with {@link ucnv_open() }. With that
- * converter, you can get its properties, set options, convert your data and
- * close the converter.</p>
- *
- * <p>Since many software programs recogize different converter names for
- * different types of converters, there are other functions in this API to
- * iterate over the converter aliases. The functions {@link ucnv_getAvailableName() },
- * {@link ucnv_getAlias() } and {@link ucnv_getStandardName() } are some of the
- * more frequently used alias functions to get this information.</p>
- *
- * <p>When a converter encounters an illegal, irregular, invalid or unmappable character
- * its default behavior is to use a substitution character to replace the
- * bad byte sequence. This behavior can be changed by using {@link ucnv_setFromUCallBack() }
- * or {@link ucnv_setToUCallBack() } on the converter. The header ucnv_err.h defines
- * many other callback actions that can be used instead of a character substitution.</p>
- *
- * <p>More information about this API can be found in our
- * <a href="http://icu-project.org/userguide/conversion.html">User's
- * Guide</a>.</p>

-/**
- * Convert a codepage buffer into Unicode one character at a time.
- * The input is completely consumed when the U_INDEX_OUTOFBOUNDS_ERROR is set.
- *
- * Advantage compared to ucnv_toUnicode() or ucnv_toUChars():
- * - Faster for small amounts of data, for most converters, e.g.,
- * US-ASCII, ISO-8859-1, UTF-8/16/32, and most "normal" charsets.
- * (For complex converters, e.g., SCSU, UTF-7 and ISO 2022 variants,
- * it uses ucnv_toUnicode() internally.)
- * - Convenient.
- *
- * Limitations compared to ucnv_toUnicode():
- * - Always assumes flush=TRUE.
- * This makes ucnv_getNextUChar() unsuitable for "streaming" conversion,
- * that is, for where the input is supplied in multiple buffers,
- * because ucnv_getNextUChar() will assume the end of the input at the end
- * of the first buffer.
- * - Does not provide offset output.
- *
- * It is possible to "mix" ucnv_getNextUChar() and ucnv_toUnicode() because
- * ucnv_getNextUChar() uses the current state of the converter
- * (unlike ucnv_toUChars() which always resets first).
- * However, if ucnv_getNextUChar() is called after ucnv_toUnicode()
- * stopped in the middle of a character sequence (with flush=FALSE),
- * then ucnv_getNextUChar() will always use the slower ucnv_toUnicode()
- * internally until the next character boundary.
- * (This is new in ICU 2.6. In earlier releases, ucnv_getNextUChar() had to
- * start at a character boundary.)
- *
- * Instead of using ucnv_getNextUChar(), it is recommended
- * to convert using ucnv_toUnicode() or ucnv_toUChars()
- * and then iterate over the text using U16_NEXT() or a UCharIterator (uiter.h)
- * or a C++ CharacterIterator or similar.
- * This allows streaming conversion and offset output, for example.
- *
- * <p>Handling of surrogate pairs and supplementary-plane code points:<br>
- * There are two different kinds of codepages that provide mappings for surrogate characters:
- * <ul>
- * <li>Codepages like UTF-8, UTF-32, and GB 18030 provide direct representations for Unicode
- * code points U+10000-U+10ffff as well as for single surrogates U+d800-U+dfff.
- * Each valid sequence will result in exactly one returned code point.
- * If a sequence results in a single surrogate, then that will be returned
- * by itself, even if a neighboring sequence encodes the matching surrogate.</li>
- * <li>Codepages like SCSU and LMBCS (and UTF-16) provide direct representations only for BMP code points
- * including surrogates. Code points in supplementary planes are represented with
- * two sequences, each encoding a surrogate.
- * For these codepages, matching pairs of surrogates will be combined into single
- * code points for returning from this function.
- * (Note that SCSU is actually a mix of these codepage types.)</li>
- * </ul></p>
- *
- * @param converter an open UConverter
- * @param source the address of a pointer to the codepage buffer, will be
- * updated to point after the bytes consumed in the conversion call.
- * @param sourceLimit points to the end of the input buffer
- * @param err fills in error status (see ucnv_toUnicode)

- * Convert from one external charset to another using two existing UConverters.
- * Internally, two conversions - ucnv_toUnicode() and ucnv_fromUnicode() -
- * are used, "pivoting" through 16-bit Unicode.
- *
- * Important: For streaming conversion (multiple function calls for successive
- * parts of a text stream), the caller must provide a pivot buffer explicitly,
- * and must preserve the pivot buffer and associated pointers from one
- * call to another. (The buffer may be moved if its contents and the relative
- * pointer positions are preserved.)
- *
- * There is a similar function, ucnv_convert(),
- * which has the following limitations:
- * - it takes charset names, not converter objects, so that
- * - two converters are opened for each call
- * - only single-string conversion is possible, not streaming operation
- * - it does not provide enough information to find out,
- * in case of failure, whether the toUnicode or
- * the fromUnicode conversion failed
- *
- * By contrast, ucnv_convertEx()
- * - takes UConverter parameters instead of charset names
- * - fully exposes the pivot buffer for streaming conversion and complete error handling
- *
- * ucnv_convertEx() also provides further convenience:
- * - an option to reset the converters at the beginning
- * (if reset==TRUE, see parameters;
- * also sets *pivotTarget=*pivotSource=pivotStart)
- * - allow NUL-terminated input
- * (only a single NUL byte, will not work for charsets with multi-byte NULs)
- * (if sourceLimit==NULL, see parameters)
- * - terminate with a NUL on output
- * (only a single NUL byte, not useful for charsets with multi-byte NULs),
- * or set U_STRING_NOT_TERMINATED_WARNING if the output exactly fills
- * the target buffer
- * - the pivot buffer can be provided internally;
- * possible only for whole-string conversion, not streaming conversion;
- * in this case, the caller will not be able to get details about where an
- * error occurred
- * (if pivotStart==NULL, see below)
- *
- * The function returns when one of the following is true:
- * - the entire source text has been converted successfully to the target buffer
- * - a target buffer overflow occurred (U_BUFFER_OVERFLOW_ERROR)
- * - a conversion error occurred
- * (other U_FAILURE(), see description of pErrorCode)
- *
- * Limitation compared to the direct use of
- * ucnv_fromUnicode() and ucnv_toUnicode():
- * ucnv_convertEx() does not provide offset information.
- *
- * Limitation compared to ucnv_fromUChars() and ucnv_toUChars():
- * ucnv_convertEx() does not support preflighting directly.
- *
- * Sample code for converting a single string from
- * one external charset to UTF-8, ignoring the location of errors:
- *
- * \code
- * int32_t
- * myToUTF8(UConverter *cnv,

- * &target, u8+capacity,
- * &s, s+length,
- * NULL, NULL, NULL, NULL,
- * TRUE, TRUE,
- * pErrorCode);
- *
- * myReleaseCachedUTF8Converter(utf8Cnv);
- *
- * // return the output string length, but without preflighting
- * return (int32_t)(target-u8);

+/**
+ * \file
+ * \brief C API: Character conversion
+ *
+ * <h2>Character Conversion C API</h2>
+ *
+ * <p>This API is used to convert codepage or character encoded data to and
+ * from UTF-16. You can open a converter with {@link ucnv_open() }. With that
+ * converter, you can get its properties, set options, convert your data and
+ * close the converter.</p>
+ *
+ * <p>Since many software programs recogize different converter names for
+ * different types of converters, there are other functions in this API to
+ * iterate over the converter aliases. The functions {@link ucnv_getAvailableName() },
+ * {@link ucnv_getAlias() } and {@link ucnv_getStandardName() } are some of the
+ * more frequently used alias functions to get this information.</p>
+ *
+ * <p>When a converter encounters an illegal, irregular, invalid or unmappable character
+ * its default behavior is to use a substitution character to replace the
+ * bad byte sequence. This behavior can be changed by using {@link ucnv_setFromUCallBack() }
+ * or {@link ucnv_setToUCallBack() } on the converter. The header ucnv_err.h defines
+ * many other callback actions that can be used instead of a character substitution.</p>
+ *
+ * <p>More information about this API can be found in our
+ * <a href="http://icu-project.org/userguide/conversion.html">User's
+ * Guide</a>.</p>

+ * (For complex converters, e.g., SCSU, UTF-7 and ISO 2022 variants,

+ * - Convenient.
+ *
+ * Limitations compared to ucnv_toUnicode():
+ * - Always assumes flush=TRUE.
+ * This makes ucnv_getNextUChar() unsuitable for "streaming" conversion,
+ * that is, for where the input is supplied in multiple buffers,

+ * of the first buffer.

+ * (unlike ucnv_toUChars() which always resets first).
+ * However, if ucnv_getNextUChar() is called after ucnv_toUnicode()

+ * then ucnv_getNextUChar() will always use the slower ucnv_toUnicode()

+ * and then iterate over the text using U16_NEXT() or a UCharIterator (uiter.h)
+ * or a C++ CharacterIterator or similar.
+ * This allows streaming conversion and offset output, for example.
+ *
+ * <p>Handling of surrogate pairs and supplementary-plane code points:<br>
+ * There are two different kinds of codepages that provide mappings for surrogate characters:
+ * <ul>
+ * <li>Codepages like UTF-8, UTF-32, and GB 18030 provide direct representations for Unicode
+ * code points U+10000-U+10ffff as well as for single surrogates U+d800-U+dfff.
+ * Each valid sequence will result in exactly one returned code point.
+ * If a sequence results in a single surrogate, then that will be returned
+ * by itself, even if a neighboring sequence encodes the matching surrogate.</li>
+ * <li>Codepages like SCSU and LMBCS (and UTF-16) provide direct representations only for BMP code points
+ * including surrogates. Code points in supplementary planes are represented with
+ * two sequences, each encoding a surrogate.
+ * For these codepages, matching pairs of surrogates will be combined into single
+ * code points for returning from this function.
+ * (Note that SCSU is actually a mix of these codepage types.)</li>

+ * Important: For streaming conversion (multiple function calls for successive

+ * There is a similar function, ucnv_convert(),

+ * - only single-string conversion is possible, not streaming operation
+ * - it does not provide enough information to find out,

+ *
+ * By contrast, ucnv_convertEx()

-/**
- * \file
- * \brief C UConverter functions to aid the writers of callbacks
- *
- * <h2> Callback API for UConverter </h2>
- *
- * These functions are provided here for the convenience of the callback
- * writer. If you are just looking for callback functions to use, please
- * see ucnv_err.h. DO NOT call these functions directly when you are
- * working with converters, unless your code has been called as a callback
- * via ucnv_setFromUCallback or ucnv_setToUCallback !!
- *
- * A note about error codes and overflow. Unlike other ICU functions,
- * these functions do not expect the error status to be U_ZERO_ERROR.
- * Callbacks must be much more careful about their error codes.
- * The error codes used here are in/out parameters, which should be passed
- * back in the callback's error parameter.
- *
- * For example, if you call ucnv_cbfromUWriteBytes to write data out
- * to the output codepage, it may return U_BUFFER_OVERFLOW_ERROR if
- * the data did not fit in the target. But this isn't a failing error,
- * in fact, ucnv_cbfromUWriteBytes may be called AGAIN with the error
- * status still U_BUFFER_OVERFLOW_ERROR to attempt to write further bytes,
- * which will also go into the internal overflow buffers.
- *
- * Concerning offsets, the 'offset' parameters here are relative to the start
- * of SOURCE. For example, Suppose the string "ABCD" was being converted
- * from Unicode into a codepage which doesn't have a mapping for 'B'.
- * 'A' will be written out correctly, but
- * The FromU Callback will be called on an unassigned character for 'B'.
- * At this point, this is the state of the world:
- * Target: A [..] [points after A]
- * Source: A B [C] D [points to C - B has been consumed]
- * 0 1 2 3
- * codePoint = "B" [the unassigned codepoint]
- *
- * Now, suppose a callback wants to write the substitution character '?' to
- * the target. It calls ucnv_cbFromUWriteBytes() to write the ?.
- * It should pass ZERO as the offset, because the offset as far as the
- * callback is concerned is relative to the SOURCE pointer [which points
- * before 'C'.] If the callback goes into the args and consumes 'C' also,
- * it would call FromUWriteBytes with an offset of 1 (and advance the source
- * pointer).

+/**
+ * \file
+ * \brief C UConverter functions to aid the writers of callbacks
+ *
+ * <h2> Callback API for UConverter </h2>
+ *
+ * These functions are provided here for the convenience of the callback
+ * writer. If you are just looking for callback functions to use, please
+ * see ucnv_err.h. DO NOT call these functions directly when you are
+ * working with converters, unless your code has been called as a callback
+ * via ucnv_setFromUCallback or ucnv_setToUCallback !!
+ *
+ * A note about error codes and overflow. Unlike other ICU functions,
+ * these functions do not expect the error status to be U_ZERO_ERROR.
+ * Callbacks must be much more careful about their error codes.
+ * The error codes used here are in/out parameters, which should be passed
+ * back in the callback's error parameter.
+ *
+ * For example, if you call ucnv_cbfromUWriteBytes to write data out
+ * to the output codepage, it may return U_BUFFER_OVERFLOW_ERROR if
+ * the data did not fit in the target. But this isn't a failing error,
+ * in fact, ucnv_cbfromUWriteBytes may be called AGAIN with the error
+ * status still U_BUFFER_OVERFLOW_ERROR to attempt to write further bytes,
+ * which will also go into the internal overflow buffers.
+ *
+ * Concerning offsets, the 'offset' parameters here are relative to the start
+ * of SOURCE. For example, Suppose the string "ABCD" was being converted
+ * from Unicode into a codepage which doesn't have a mapping for 'B'.
+ * 'A' will be written out correctly, but
+ * The FromU Callback will be called on an unassigned character for 'B'.
+ * At this point, this is the state of the world:
+ * Target: A [..] [points after A]
+ * Source: A B [C] D [points to C - B has been consumed]
+ * 0 1 2 3
+ * codePoint = "B" [the unassigned codepoint]
+ *
+ * Now, suppose a callback wants to write the substitution character '?' to
+ * the target. It calls ucnv_cbFromUWriteBytes() to write the ?.
+ * It should pass ZERO as the offset, because the offset as far as the
+ * callback is concerned is relative to the SOURCE pointer [which points
+ * before 'C'.] If the callback goes into the args and consumes 'C' also,
+ * it would call FromUWriteBytes with an offset of 1 (and advance the source
+ * pointer).

-/**
- * \file
- * \brief C UConverter predefined error callbacks
- *
- * <h2>Error Behaviour Functions</h2>
- * Defines some error behaviour functions called by ucnv_{from,to}Unicode
- * These are provided as part of ICU and many are stable, but they
- * can also be considered only as an example of what can be done with
- * callbacks. You may of course write your own.
- *
- * If you want to write your own, you may also find the functions from
- * ucnv_cb.h useful when writing your own callbacks.
- *
- * These functions, although public, should NEVER be called directly.
- * They should be used as parameters to the ucnv_setFromUCallback
- * and ucnv_setToUCallback functions, to set the behaviour of a converter
- * when it encounters ILLEGAL/UNMAPPED/INVALID sequences.
- *
- * usage example: 'STOP' doesn't need any context, but newContext
- * could be set to something other than 'NULL' if needed. The available
- * contexts in this header can modify the default behavior of the callback.
- *
- * \code
- * UErrorCode err = U_ZERO_ERROR;
- * UConverter *myConverter = ucnv_open("ibm-949", &err);
- * const void *oldContext;
- * UConverterFromUCallback oldAction;
- *
- *
- * if (U_SUCCESS(err))
- * {
- * ucnv_setFromUCallBack(myConverter,
- * UCNV_FROM_U_CALLBACK_STOP,
- * NULL,
- * &oldAction,
- * &oldContext,
- * &status);
- * }
- * \endcode
- *
- * The code above tells "myConverter" to stop when it encounters an
- * ILLEGAL/TRUNCATED/INVALID sequences when it is used to convert from
- * Unicode -> Codepage. The behavior from Codepage to Unicode is not changed,
- * and ucnv_setToUCallBack would need to be called in order to change
- * that behavior too.
- *
- * Here is an example with a context:
- *
- * \code
- * UErrorCode err = U_ZERO_ERROR;
- * UConverter *myConverter = ucnv_open("ibm-949", &err);
- * const void *oldContext;
- * UConverterFromUCallback oldAction;
- *
- *
- * if (U_SUCCESS(err))
- * {
- * ucnv_setToUCallBack(myConverter,
- * UCNV_TO_U_CALLBACK_SUBSTITUTE,
- * UCNV_SUB_STOP_ON_ILLEGAL,
- * &oldAction,
- * &oldContext,
- * &status);
- * }
- * \endcode
- *
- * The code above tells "myConverter" to stop when it encounters an
- * ILLEGAL/TRUNCATED/INVALID sequences when it is used to convert from
- * Codepage -> Unicode. Any unmapped and legal characters will be
- * substituted to be the default substitution character.

+/**
+ * \file
+ * \brief C UConverter predefined error callbacks
+ *
+ * <h2>Error Behaviour Functions</h2>
+ * Defines some error behaviour functions called by ucnv_{from,to}Unicode
+ * These are provided as part of ICU and many are stable, but they
+ * can also be considered only as an example of what can be done with
+ * callbacks. You may of course write your own.
+ *
+ * If you want to write your own, you may also find the functions from
+ * ucnv_cb.h useful when writing your own callbacks.
+ *
+ * These functions, although public, should NEVER be called directly.
+ * They should be used as parameters to the ucnv_setFromUCallback
+ * and ucnv_setToUCallback functions, to set the behaviour of a converter
+ * when it encounters ILLEGAL/UNMAPPED/INVALID sequences.
+ *
+ * usage example: 'STOP' doesn't need any context, but newContext
+ * could be set to something other than 'NULL' if needed. The available
+ * contexts in this header can modify the default behavior of the callback.
+ *
+ * \code
+ * UErrorCode err = U_ZERO_ERROR;
+ * UConverter *myConverter = ucnv_open("ibm-949", &err);
+ * const void *oldContext;
+ * UConverterFromUCallback oldAction;
+ *
+ *
+ * if (U_SUCCESS(err))
+ * {
+ * ucnv_setFromUCallBack(myConverter,
+ * UCNV_FROM_U_CALLBACK_STOP,
+ * NULL,
+ * &oldAction,
+ * &oldContext,
+ * &status);
+ * }
+ * \endcode
+ *
+ * The code above tells "myConverter" to stop when it encounters an
+ * ILLEGAL/TRUNCATED/INVALID sequences when it is used to convert from
+ * Unicode -> Codepage. The behavior from Codepage to Unicode is not changed,
+ * and ucnv_setToUCallBack would need to be called in order to change
+ * that behavior too.
+ *
+ * Here is an example with a context:
+ *
+ * \code
+ * UErrorCode err = U_ZERO_ERROR;
+ * UConverter *myConverter = ucnv_open("ibm-949", &err);
+ * const void *oldContext;
+ * UConverterFromUCallback oldAction;
+ *
+ *
+ * if (U_SUCCESS(err))
+ * {
+ * ucnv_setToUCallBack(myConverter,
+ * UCNV_TO_U_CALLBACK_SUBSTITUTE,
+ * UCNV_SUB_STOP_ON_ILLEGAL,
+ * &oldAction,
+ * &oldContext,
+ * &status);
+ * }
+ * \endcode
+ *
+ * The code above tells "myConverter" to stop when it encounters an
+ * ILLEGAL/TRUNCATED/INVALID sequences when it is used to convert from
+ * Codepage -> Unicode. Any unmapped and legal characters will be
+ * substituted to be the default substitution character.

- * <em>Important: </em>The ICU collation service has been reimplemented
- * in order to achieve better performance and UCA compliance.
- * For details, see the

- * <p>
- * Collation service provides correct sorting orders for most locales supported in ICU.
- * If specific data for a locale is not available, the orders eventually falls back
- * to the <a href="http://www.unicode.org/unicode/reports/tr10/">UCA sort order</a>.
- * <p>
- * Sort ordering may be customized by providing your own set of rules. For more on

+ * \brief C API: Collator
+ *
+ * <h2> Collator C API </h2>
+ *
+ * The C API for Collator performs locale-sensitive
+ * string comparison. You use this service to build
+ * searching and sorting routines for natural language text.
+ * <em>Important: </em>The ICU collation service has been reimplemented
+ * in order to achieve better performance and UCA compliance.
+ * For details, see the
+ * <a href="http://source.icu-project.org/repos/icu/icuhtml/trunk/design/collation/ICU_collation_design.htm">
+ * collation design document</a>.
+ * <p>
+ * For more information about the collation service see
+ * <a href="http://icu-project.org/userguide/Collate_Intro.html">the users guide</a>.
+ * <p>
+ * Collation service provides correct sorting orders for most locales supported in ICU.
+ * If specific data for a locale is not available, the orders eventually falls back
+ * to the <a href="http://www.unicode.org/unicode/reports/tr10/">UCA sort order</a>.
+ * <p>
+ * Sort ordering may be customized by providing your own set of rules. For more on
+ * this subject see the
+ * <a href="http://icu-project.org/userguide/Collate_Customization.html">
+ * Collation customization</a> section of the users guide.

- * \file
- * \brief C API: UCollationElements
- *
- * The UCollationElements API is used as an iterator to walk through each
- * character of an international string. Use the iterator to return the
- * ordering priority of the positioned character. The ordering priority of a
- * character, which we refer to as a key, defines how a character is collated
- * in the given collation object.
- * For example, consider the following in Spanish:
- * <pre>
- * . "ca" -> the first key is key('c') and second key is key('a').
- * . "cha" -> the first key is key('ch') and second key is key('a').
- * </pre>
- * And in German,
- * <pre>
- * . "<ae ligature>b"-> the first key is key('a'), the second key is key('e'), and
- * . the third key is key('b').
- * </pre>
- * <p>Example of the iterator usage: (without error checking)
- * <pre>
- * . void CollationElementIterator_Example()
- * . {
- * . UChar *s;
- * . t_int32 order, primaryOrder;
- * . UCollationElements *c;
- * . UCollatorOld *coll;
- * . UErrorCode success = U_ZERO_ERROR;
- * . s=(UChar*)malloc(sizeof(UChar) * (strlen("This is a test")+1) );
- * . u_uastrcpy(s, "This is a test");
- * . coll = ucol_open(NULL, &success);
- * . c = ucol_openElements(coll, str, u_strlen(str), &status);
- * . order = ucol_next(c, &success);
- * . ucol_reset(c);
- * . order = ucol_prev(c, &success);
- * . free(s);
- * . ucol_close(coll);
- * . ucol_closeElements(c);
- * . }
- * </pre>
- * <p>
- * ucol_next() returns the collation order of the next.
- * ucol_prev() returns the collation order of the previous character.
- * The Collation Element Iterator moves only in one direction between calls to
- * ucol_reset. That is, ucol_next() and ucol_prev can not be inter-used.
- * Whenever ucol_prev is to be called after ucol_next() or vice versa,
- * ucol_reset has to be called first to reset the status, shifting pointers to
- * either the end or the start of the string. Hence at the next call of
- * ucol_prev or ucol_next, the first or last collation order will be returned.
- * If a change of direction is done without a ucol_reset, the result is
- * undefined.
- * The result of a forward iterate (ucol_next) and reversed result of the
- * backward iterate (ucol_prev) on the same string are equivalent, if
- * collation orders with the value UCOL_IGNORABLE are ignored.
- * Character based on the comparison level of the collator. A collation order
- * consists of primary order, secondary order and tertiary order. The data
- * type of the collation order is <strong>t_int32</strong>.

+ * The UCollationElements API is used as an iterator to walk through each
+ * character of an international string. Use the iterator to return the
+ * ordering priority of the positioned character. The ordering priority of a
+ * character, which we refer to as a key, defines how a character is collated
+ * in the given collation object.
+ * For example, consider the following in Spanish:
+ * <pre>
+ * . "ca" -> the first key is key('c') and second key is key('a').
+ * . "cha" -> the first key is key('ch') and second key is key('a').
+ * </pre>
+ * And in German,
+ * <pre>
+ * . "<ae ligature>b"-> the first key is key('a'), the second key is key('e'), and
+ * . the third key is key('b').
+ * </pre>
+ * <p>Example of the iterator usage: (without error checking)
+ * <pre>
+ * . void CollationElementIterator_Example()
+ * . {
+ * . UChar *s;
+ * . t_int32 order, primaryOrder;
+ * . UCollationElements *c;
+ * . UCollatorOld *coll;
+ * . UErrorCode success = U_ZERO_ERROR;
+ * . s=(UChar*)malloc(sizeof(UChar) * (strlen("This is a test")+1) );
+ * . u_uastrcpy(s, "This is a test");
+ * . coll = ucol_open(NULL, &success);
+ * . c = ucol_openElements(coll, str, u_strlen(str), &status);
+ * . order = ucol_next(c, &success);
+ * . ucol_reset(c);
+ * . order = ucol_prev(c, &success);
+ * . free(s);
+ * . ucol_close(coll);
+ * . ucol_closeElements(c);
+ * . }
+ * </pre>
+ * <p>
+ * ucol_next() returns the collation order of the next.
+ * ucol_prev() returns the collation order of the previous character.
+ * The Collation Element Iterator moves only in one direction between calls to
+ * ucol_reset. That is, ucol_next() and ucol_prev can not be inter-used.
+ * Whenever ucol_prev is to be called after ucol_next() or vice versa,
+ * ucol_reset has to be called first to reset the status, shifting pointers to
+ * either the end or the start of the string. Hence at the next call of
+ * ucol_prev or ucol_next, the first or last collation order will be returned.
+ * If a change of direction is done without a ucol_reset, the result is
+ * undefined.
+ * The result of a forward iterate (ucol_next) and reversed result of the
+ * backward iterate (ucol_prev) on the same string are equivalent, if
+ * collation orders with the value UCOL_IGNORABLE are ignored.
+ * Character based on the comparison level of the collator. A collation order
+ * consists of primary order, secondary order and tertiary order. The data
+ * type of the collation order is <strong>t_int32</strong>.
+ *

- * This API provides a facility for detecting the
- * charset or encoding of character data in an unknown text format.
- * The input data can be from an array of bytes.
- * <p>
- * Character set detection is at best an imprecise operation. The detection
- * process will attempt to identify the charset that best matches the characteristics

- * <p>
- * For best accuracy in charset detection, the input data should be primarily
- * in a single language, and a minimum of a few hundred bytes worth of plain text
- * in the language are needed. The detection process will attempt to
- * ignore html or xml style markup that could otherwise obscure the content.

- * \file
- * \brief C API: DateFormat
- *
- * <h2> Date Format C API</h2>
- *
- * Date Format C API consists of functions that convert dates and
- * times from their internal representations to textual form and back again in a
- * language-independent manner. Converting from the internal representation (milliseconds
- * since midnight, January 1, 1970) to text is known as "formatting," and converting
- * from text to millis is known as "parsing." We currently define only one concrete
- * structure UDateFormat, which can handle pretty much all normal
- * date formatting and parsing actions.
- * <P>
- * Date Format helps you to format and parse dates for any locale. Your code can
- * be completely independent of the locale conventions for months, days of the
- * week, or even the calendar format: lunar vs. solar.
- * <P>
- * To format a date for the current Locale with default time and date style,
- * use one of the static factory methods:
- * <pre>
- * \code
- * UErrorCode status = U_ZERO_ERROR;
- * UChar *myString;
- * int32_t myStrlen = 0;
- * UDateFormat* dfmt = udat_open(UDAT_DEFAULT, UDAT_DEFAULT, NULL, NULL, -1, NULL, -1, &status);
- * myStrlen = udat_format(dfmt, myDate, NULL, myStrlen, NULL, &status);
- * if (status==U_BUFFER_OVERFLOW_ERROR){
- * status=U_ZERO_ERROR;
- * myString=(UChar*)malloc(sizeof(UChar) * (myStrlen+1) );
- * udat_format(dfmt, myDate, myString, myStrlen+1, NULL, &status);
- * }
- * \endcode
- * </pre>
- * If you are formatting multiple numbers, it is more efficient to get the
- * format and use it multiple times so that the system doesn't have to fetch the
- * information about the local language and country conventions multiple times.
- * <pre>
- * \code
- * UErrorCode status = U_ZERO_ERROR;
- * int32_t i, myStrlen = 0;
- * UChar* myString;
- * char buffer[1024];
- * UDate myDateArr[] = { 0.0, 100000000.0, 2000000000.0 }; // test values
- * UDateFormat* df = udat_open(UDAT_DEFAULT, UDAT_DEFAULT, NULL, NULL, -1, NULL, 0, &status);
- * for (i = 0; i < 3; i++) {
- * myStrlen = udat_format(df, myDateArr[i], NULL, myStrlen, NULL, &status);
- * if(status == U_BUFFER_OVERFLOW_ERROR){
- * status = U_ZERO_ERROR;
- * myString = (UChar*)malloc(sizeof(UChar) * (myStrlen+1) );
- * udat_format(df, myDateArr[i], myString, myStrlen+1, NULL, &status);
- * printf("%s\n", u_austrcpy(buffer, myString) );
- * free(myString);
- * }
- * }
- * \endcode
- * </pre>
- * To get specific fields of a date, you can use UFieldPosition to
- * get specific fields.
- * <pre>
- * \code
- * UErrorCode status = U_ZERO_ERROR;
- * UFieldPosition pos;
- * UChar *myString;
- * int32_t myStrlen = 0;
- * char buffer[1024];
- *
- * pos.field = 1; // Same as the DateFormat::EField enum
- * UDateFormat* dfmt = udat_open(UDAT_DEFAULT, UDAT_DEFAULT, NULL, -1, NULL, 0, &status);
- * myStrlen = udat_format(dfmt, myDate, NULL, myStrlen, &pos, &status);
- * if (status==U_BUFFER_OVERFLOW_ERROR){
- * status=U_ZERO_ERROR;
- * myString=(UChar*)malloc(sizeof(UChar) * (myStrlen+1) );
- * udat_format(dfmt, myDate, myString, myStrlen+1, &pos, &status);
- * }
- * printf("date format: %s\n", u_austrcpy(buffer, myString));
- * buffer[pos.endIndex] = 0; // NULL terminate the string.
- * printf("UFieldPosition position equals %s\n", &buffer[pos.beginIndex]);
- * \endcode
- * </pre>
- * To format a date for a different Locale, specify it in the call to
- * udat_open()
- * <pre>
- * \code
- * UDateFormat* df = udat_open(UDAT_SHORT, UDAT_SHORT, "fr_FR", NULL, -1, NULL, 0, &status);
- * \endcode
- * </pre>
- * You can use a DateFormat API udat_parse() to parse.
- * <pre>
- * \code
- * UErrorCode status = U_ZERO_ERROR;
- * int32_t parsepos=0;
- * UDate myDate = udat_parse(df, myString, u_strlen(myString), &parsepos, &status);
- * \endcode
- * </pre>
- * You can pass in different options for the arguments for date and time style
- * to control the length of the result; from SHORT to MEDIUM to LONG to FULL.
- * The exact result depends on the locale, but generally:
- * see UDateFormatStyle for more details
- * <ul type=round>
- * <li> UDAT_SHORT is completely numeric, such as 12/13/52 or 3:30pm
- * <li> UDAT_MEDIUM is longer, such as Jan 12, 1952
- * <li> UDAT_LONG is longer, such as January 12, 1952 or 3:30:32pm
- * <li> UDAT_FULL is pretty completely specified, such as
- * Tuesday, April 12, 1952 AD or 3:30:42pm PST.
- * </ul>
- * You can also set the time zone on the format if you wish.
- * <P>
- * You can also use forms of the parse and format methods with Parse Position and
- * UFieldPosition to allow you to
- * <ul type=round>
- * <li> Progressively parse through pieces of a string.
- * <li> Align any particular field, or find out where it is for selection
- * on the screen.
- * </ul>

+ * \file
+ * \brief C API: DateFormat
+ *
+ * <h2> Date Format C API</h2>
+ *
+ * Date Format C API consists of functions that convert dates and
+ * times from their internal representations to textual form and back again in a
+ * language-independent manner. Converting from the internal representation (milliseconds
+ * since midnight, January 1, 1970) to text is known as "formatting," and converting
+ * from text to millis is known as "parsing." We currently define only one concrete
+ * structure UDateFormat, which can handle pretty much all normal
+ * date formatting and parsing actions.
+ * <P>
+ * Date Format helps you to format and parse dates for any locale. Your code can
+ * be completely independent of the locale conventions for months, days of the
+ * week, or even the calendar format: lunar vs. solar.
+ * <P>
+ * To format a date for the current Locale with default time and date style,
+ * use one of the static factory methods:
+ * <pre>
+ * \code
+ * UErrorCode status = U_ZERO_ERROR;
+ * UChar *myString;
+ * int32_t myStrlen = 0;
+ * UDateFormat* dfmt = udat_open(UDAT_DEFAULT, UDAT_DEFAULT, NULL, NULL, -1, NULL, -1, &status);
+ * myStrlen = udat_format(dfmt, myDate, NULL, myStrlen, NULL, &status);
+ * if (status==U_BUFFER_OVERFLOW_ERROR){
+ * status=U_ZERO_ERROR;
+ * myString=(UChar*)malloc(sizeof(UChar) * (myStrlen+1) );
+ * udat_format(dfmt, myDate, myString, myStrlen+1, NULL, &status);
+ * }
+ * \endcode
+ * </pre>
+ * If you are formatting multiple numbers, it is more efficient to get the
+ * format and use it multiple times so that the system doesn't have to fetch the
+ * information about the local language and country conventions multiple times.
+ * <pre>
+ * \code
+ * UErrorCode status = U_ZERO_ERROR;
+ * int32_t i, myStrlen = 0;
+ * UChar* myString;
+ * char buffer[1024];
+ * UDate myDateArr[] = { 0.0, 100000000.0, 2000000000.0 }; // test values
+ * UDateFormat* df = udat_open(UDAT_DEFAULT, UDAT_DEFAULT, NULL, NULL, -1, NULL, 0, &status);
+ * for (i = 0; i < 3; i++) {
+ * myStrlen = udat_format(df, myDateArr[i], NULL, myStrlen, NULL, &status);
+ * if(status == U_BUFFER_OVERFLOW_ERROR){
+ * status = U_ZERO_ERROR;
+ * myString = (UChar*)malloc(sizeof(UChar) * (myStrlen+1) );
+ * udat_format(df, myDateArr[i], myString, myStrlen+1, NULL, &status);
+ * printf("%s\n", u_austrcpy(buffer, myString) );
+ * free(myString);
+ * }
+ * }
+ * \endcode
+ * </pre>
+ * To get specific fields of a date, you can use UFieldPosition to
+ * get specific fields.
+ * <pre>
+ * \code
+ * UErrorCode status = U_ZERO_ERROR;
+ * UFieldPosition pos;
+ * UChar *myString;
+ * int32_t myStrlen = 0;
+ * char buffer[1024];
+ *
+ * pos.field = 1; // Same as the DateFormat::EField enum
+ * UDateFormat* dfmt = udat_open(UDAT_DEFAULT, UDAT_DEFAULT, NULL, -1, NULL, 0, &status);
+ * myStrlen = udat_format(dfmt, myDate, NULL, myStrlen, &pos, &status);
+ * if (status==U_BUFFER_OVERFLOW_ERROR){
+ * status=U_ZERO_ERROR;
+ * myString=(UChar*)malloc(sizeof(UChar) * (myStrlen+1) );
+ * udat_format(dfmt, myDate, myString, myStrlen+1, &pos, &status);
+ * }
+ * printf("date format: %s\n", u_austrcpy(buffer, myString));
+ * buffer[pos.endIndex] = 0; // NULL terminate the string.
+ * printf("UFieldPosition position equals %s\n", &buffer[pos.beginIndex]);
+ * \endcode
+ * </pre>
+ * To format a date for a different Locale, specify it in the call to
+ * udat_open()
+ * <pre>
+ * \code
+ * UDateFormat* df = udat_open(UDAT_SHORT, UDAT_SHORT, "fr_FR", NULL, -1, NULL, 0, &status);
+ * \endcode
+ * </pre>
+ * You can use a DateFormat API udat_parse() to parse.
+ * <pre>
+ * \code
+ * UErrorCode status = U_ZERO_ERROR;
+ * int32_t parsepos=0;
+ * UDate myDate = udat_parse(df, myString, u_strlen(myString), &parsepos, &status);
+ * \endcode
+ * </pre>
+ * You can pass in different options for the arguments for date and time style
+ * to control the length of the result; from SHORT to MEDIUM to LONG to FULL.
+ * The exact result depends on the locale, but generally:
+ * see UDateFormatStyle for more details
+ * <ul type=round>
+ * <li> UDAT_SHORT is completely numeric, such as 12/13/52 or 3:30pm
+ * <li> UDAT_MEDIUM is longer, such as Jan 12, 1952
+ * <li> UDAT_LONG is longer, such as January 12, 1952 or 3:30:32pm
+ * <li> UDAT_FULL is pretty completely specified, such as
+ * Tuesday, April 12, 1952 AD or 3:30:42pm PST.
+ * </ul>
+ * You can also set the time zone on the format if you wish.
+ * <P>
+ * You can also use forms of the parse and format methods with Parse Position and
+ * UFieldPosition to allow you to
+ * <ul type=round>
+ * <li> Progressively parse through pieces of a string.
+ * <li> Align any particular field, or find out where it is for selection
+ * on the screen.
+ * </ul>

+ * \brief C API: Wrapper for DateTimePatternGenerator (unicode/dtptngen.h).
+ *
+ * UDateTimePatternGenerator provides flexible generation of date format patterns,
+ * like "yy-MM-dd". The user can build up the generator by adding successive
+ * patterns. Once that is done, a query can be made using a "skeleton", which is
+ * a pattern which just includes the desired fields and lengths. The generator
+ * will return the "best fit" pattern corresponding to that skeleton.
+ * <p>The main method people will use is udatpg_getBestPattern, since normally
+ * UDateTimePatternGenerator is pre-built with data from a particular locale.
+ * However, generators can be built directly from other data as well.
+ * <p><i>Issue: may be useful to also have a function that returns the list of
+ * fields in a pattern, in order, since we have that internally.
+ * That would be useful for getting the UI order of field elements.</i>

- * \brief C API: Internationalized Domain Names in Applications Tranformation
- *
- * UIDNA API implements the IDNA protocol as defined in the IDNA RFC
- * (http://www.ietf.org/rfc/rfc3490.txt).
- * The RFC defines 2 operations: ToASCII and ToUnicode. Domain labels
- * containing non-ASCII code points are required to be processed by
- * ToASCII operation before passing it to resolver libraries. Domain names
- * that are obtained from resolver libraries are required to be processed by
- * ToUnicode operation before displaying the domain name to the user.
- * IDNA requires that implementations process input strings with Nameprep
- * (http://www.ietf.org/rfc/rfc3491.txt),
- * which is a profile of Stringprep (http://www.ietf.org/rfc/rfc3454.txt),
- * and then with Punycode (http://www.ietf.org/rfc/rfc3492.txt).
- * Implementations of IDNA MUST fully implement Nameprep and Punycode;
- * neither Nameprep nor Punycode are optional.
- * The input and output of ToASCII and ToUnicode operations are Unicode
- * and are designed to be chainable, i.e., applying ToASCII or ToUnicode operations
- * multiple times to an input string will yield the same result as applying the operation
- * once.
- * ToUnicode(ToUnicode(ToUnicode...(ToUnicode(string)))) == ToUnicode(string)
- * ToASCII(ToASCII(ToASCII...(ToASCII(string))) == ToASCII(string).

+ * \brief C API: Internationalized Domain Names in Applications Tranformation
+ *
+ * UIDNA API implements the IDNA protocol as defined in the IDNA RFC
+ * (http://www.ietf.org/rfc/rfc3490.txt).
+ * The RFC defines 2 operations: ToASCII and ToUnicode. Domain labels
+ * containing non-ASCII code points are required to be processed by
+ * ToASCII operation before passing it to resolver libraries. Domain names
+ * that are obtained from resolver libraries are required to be processed by
+ * ToUnicode operation before displaying the domain name to the user.
+ * IDNA requires that implementations process input strings with Nameprep
+ * (http://www.ietf.org/rfc/rfc3491.txt),
+ * which is a profile of Stringprep (http://www.ietf.org/rfc/rfc3454.txt),
+ * and then with Punycode (http://www.ietf.org/rfc/rfc3492.txt).
+ * Implementations of IDNA MUST fully implement Nameprep and Punycode;
+ * neither Nameprep nor Punycode are optional.
+ * The input and output of ToASCII and ToUnicode operations are Unicode
+ * and are designed to be chainable, i.e., applying ToASCII or ToUnicode operations
+ * multiple times to an input string will yield the same result as applying the operation
+ * once.
+ * ToUnicode(ToUnicode(ToUnicode...(ToUnicode(string)))) == ToUnicode(string)
+ * ToASCII(ToASCII(ToASCII...(ToASCII(string))) == ToASCII(string).

- * limit, and previous() only checks the current index against the start,
- * to see if the iterator already reached the end of the iteration range.

- * The assumption - in all iterators - is that the index is moved via the API,

- * \brief C API: Locale
- *
- * <h2> ULoc C API for Locale </h2>
- * A <code>Locale</code> represents a specific geographical, political,
- * or cultural region. An operation that requires a <code>Locale</code> to perform
- * its task is called <em>locale-sensitive</em> and uses the <code>Locale</code>
- * to tailor information for the user. For example, displaying a number
- * is a locale-sensitive operation--the number should be formatted
- * according to the customs/conventions of the user's native country,
- * region, or culture. In the C APIs, a locales is simply a const char string.
- *
- * <P>
- * You create a <code>Locale</code> with one of the three options listed below.
- * Each of the component is separated by '_' in the locale string.
- * \htmlonly<blockquote>\endhtmlonly
- * <pre>
- * \code
- * newLanguage
- *
- * newLanguage + newCountry
- *
- * newLanguage + newCountry + newVariant
- * \endcode
- * </pre>
- * \htmlonly</blockquote>\endhtmlonly
- * The first option is a valid <STRONG>ISO
- * Language Code.</STRONG> These codes are the lower-case two-letter
- * codes as defined by ISO-639.
- * You can find a full list of these codes at a number of sites, such as:
- * <BR><a href ="http://www.ics.uci.edu/pub/ietf/http/related/iso639.txt">
- * http://www.ics.uci.edu/pub/ietf/http/related/iso639.txt</a>
- *
- * <P>
- * The second option includes an additonal <STRONG>ISO Country
- * Code.</STRONG> These codes are the upper-case two-letter codes
- * as defined by ISO-3166.
- * You can find a full list of these codes at a number of sites, such as:
- * <BR><a href="http://www.chemie.fu-berlin.de/diverse/doc/ISO_3166.html">
- * http://www.chemie.fu-berlin.de/diverse/doc/ISO_3166.html</a>
- *
- * <P>
- * The third option requires another additonal information--the
- * <STRONG>Variant.</STRONG>
- * The Variant codes are vendor and browser-specific.
- * For example, use WIN for Windows, MAC for Macintosh, and POSIX for POSIX.
- * Where there are two variants, separate them with an underscore, and
- * put the most important one first. For
- * example, a Traditional Spanish collation might be referenced, with
- * "ES", "ES", "Traditional_WIN".
- *
- * <P>
- * Because a <code>Locale</code> is just an identifier for a region,
- * no validity check is performed when you specify a <code>Locale</code>.
- * If you want to see whether particular resources are available for the
- * <code>Locale</code> you asked for, you must query those resources. For
- * example, ask the <code>UNumberFormat</code> for the locales it supports
- * using its <code>getAvailable</code> method.
- * <BR><STRONG>Note:</STRONG> When you ask for a resource for a particular
- * locale, you get back the best available match, not necessarily
- * precisely what you asked for. For more information, look at
- * <code>UResourceBundle</code>.
- *
- * <P>
- * The <code>Locale</code> provides a number of convenient constants
- * that you can use to specify the commonly used
- * locales. For example, the following refers to a locale
- * for the United States:
- * \htmlonly<blockquote>\endhtmlonly
- * <pre>
- * \code
- * ULOC_US
- * \endcode
- * </pre>
- * \htmlonly</blockquote>\endhtmlonly
- *
- * <P>
- * Once you've specified a locale you can query it for information about
- * itself. Use <code>uloc_getCountry</code> to get the ISO Country Code and
- * <code>uloc_getLanguage</code> to get the ISO Language Code. You can
- * use <code>uloc_getDisplayCountry</code> to get the
- * name of the country suitable for displaying to the user. Similarly,
- * you can use <code>uloc_getDisplayLanguage</code> to get the name of
- * the language suitable for displaying to the user. Interestingly,
- * the <code>uloc_getDisplayXXX</code> methods are themselves locale-sensitive
- * and have two versions: one that uses the default locale and one
- * that takes a locale as an argument and displays the name or country in
- * a language appropriate to that locale.
- *
- * <P>
- * The ICU provides a number of services that perform locale-sensitive
- * operations. For example, the <code>unum_xxx</code> functions format
- * numbers, currency, or percentages in a locale-sensitive manner.
- * </P>
- * \htmlonly<blockquote>\endhtmlonly
- * <pre>
- * \code
- * UErrorCode success = U_ZERO_ERROR;
- * UNumberFormat *nf;
- * const char* myLocale = "fr_FR";
- *
- * nf = unum_open( UNUM_DEFAULT, NULL, success );
- * unum_close(nf);
- * nf = unum_open( UNUM_CURRENCY, NULL, success );
- * unum_close(nf);
- * nf = unum_open( UNUM_PERCENT, NULL, success );
- * unum_close(nf);
- * \endcode
- * </pre>
- * \htmlonly</blockquote>\endhtmlonly
- * Each of these methods has two variants; one with an explicit locale
- * and one without; the latter using the default locale.
- * \htmlonly<blockquote>\endhtmlonly
- * <pre>
- * \code
- *
- * nf = unum_open( UNUM_DEFAULT, myLocale, success );
- * unum_close(nf);
- * nf = unum_open( UNUM_CURRENCY, myLocale, success );
- * unum_close(nf);
- * nf = unum_open( UNUM_PERCENT, myLocale, success );
- * unum_close(nf);
- * \endcode
- * </pre>
- * \htmlonly</blockquote>\endhtmlonly
- * A <code>Locale</code> is the mechanism for identifying the kind of services
- * (<code>UNumberFormat</code>) that you would like to get. The locale is
- * <STRONG>just</STRONG> a mechanism for identifying these services.
- *
- * <P>
- * Each international serivce that performs locale-sensitive operations
- * allows you
- * to get all the available objects of that type. You can sift
- * through these objects by language, country, or variant,
- * and use the display names to present a menu to the user.
- * For example, you can create a menu of all the collation objects
- * suitable for a given language. Such classes implement these
- * three class methods:
- * \htmlonly<blockquote>\endhtmlonly
- * <pre>
- * \code
- * const char* uloc_getAvailable(int32_t index);
- * int32_t uloc_countAvailable();
- * int32_t
- * uloc_getDisplayName(const char* localeID,
- * const char* inLocaleID,
- * UChar* result,
- * int32_t maxResultSize,
- * UErrorCode* err);
- *
- * \endcode
- * </pre>
- * \htmlonly</blockquote>\endhtmlonly
- * <P>
- * Concerning POSIX/RFC1766 Locale IDs,
- * the getLanguage/getCountry/getVariant/getName functions do understand
- * the POSIX type form of language_COUNTRY.ENCODING\@VARIANT
- * and if there is not an ICU-stype variant, uloc_getVariant() for example
- * will return the one listed after the \@at sign. As well, the hyphen
- * "-" is recognized as a country/variant separator similarly to RFC1766.
- * So for example, "en-us" will be interpreted as en_US.
- * As a result, uloc_getName() is far from a no-op, and will have the
- * effect of converting POSIX/RFC1766 IDs into ICU form, although it does
- * NOT map any of the actual codes (i.e. russian->ru) in any way.
- * Applications should call uloc_getName() at the point where a locale ID
- * is coming from an external source (user entry, OS, web browser)
- * and pass the resulting string to other ICU functions. For example,
- * don't use de-de\@EURO as an argument to resourcebundle.

+/**
+ * \file
+ * \brief C API: Locale
+ *
+ * <h2> ULoc C API for Locale </h2>
+ * A <code>Locale</code> represents a specific geographical, political,
+ * or cultural region. An operation that requires a <code>Locale</code> to perform
+ * its task is called <em>locale-sensitive</em> and uses the <code>Locale</code>
+ * to tailor information for the user. For example, displaying a number
+ * is a locale-sensitive operation--the number should be formatted
+ * according to the customs/conventions of the user's native country,
+ * region, or culture. In the C APIs, a locales is simply a const char string.
+ *
+ * <P>
+ * You create a <code>Locale</code> with one of the three options listed below.
+ * Each of the component is separated by '_' in the locale string.
+ * \htmlonly<blockquote>\endhtmlonly
+ * <pre>
+ * \code
+ * newLanguage
+ *
+ * newLanguage + newCountry
+ *
+ * newLanguage + newCountry + newVariant
+ * \endcode
+ * </pre>
+ * \htmlonly</blockquote>\endhtmlonly
+ * The first option is a valid <STRONG>ISO
+ * Language Code.</STRONG> These codes are the lower-case two-letter
+ * codes as defined by ISO-639.
+ * You can find a full list of these codes at a number of sites, such as:
+ * <BR><a href ="http://www.ics.uci.edu/pub/ietf/http/related/iso639.txt">
+ * http://www.ics.uci.edu/pub/ietf/http/related/iso639.txt</a>
+ *
+ * <P>
+ * The second option includes an additonal <STRONG>ISO Country
+ * Code.</STRONG> These codes are the upper-case two-letter codes
+ * as defined by ISO-3166.
+ * You can find a full list of these codes at a number of sites, such as:
+ * <BR><a href="http://www.chemie.fu-berlin.de/diverse/doc/ISO_3166.html">
+ * http://www.chemie.fu-berlin.de/diverse/doc/ISO_3166.html</a>
+ *
+ * <P>
+ * The third option requires another additonal information--the
+ * <STRONG>Variant.</STRONG>
+ * The Variant codes are vendor and browser-specific.
+ * For example, use WIN for Windows, MAC for Macintosh, and POSIX for POSIX.
+ * Where there are two variants, separate them with an underscore, and
+ * put the most important one first. For
+ * example, a Traditional Spanish collation might be referenced, with
+ * "ES", "ES", "Traditional_WIN".
+ *
+ * <P>
+ * Because a <code>Locale</code> is just an identifier for a region,
+ * no validity check is performed when you specify a <code>Locale</code>.
+ * If you want to see whether particular resources are available for the
+ * <code>Locale</code> you asked for, you must query those resources. For
+ * example, ask the <code>UNumberFormat</code> for the locales it supports
+ * using its <code>getAvailable</code> method.
+ * <BR><STRONG>Note:</STRONG> When you ask for a resource for a particular
+ * locale, you get back the best available match, not necessarily
+ * precisely what you asked for. For more information, look at
+ * <code>UResourceBundle</code>.
+ *
+ * <P>
+ * The <code>Locale</code> provides a number of convenient constants
+ * that you can use to specify the commonly used
+ * locales. For example, the following refers to a locale
+ * for the United States:
+ * \htmlonly<blockquote>\endhtmlonly
+ * <pre>
+ * \code
+ * ULOC_US
+ * \endcode
+ * </pre>
+ * \htmlonly</blockquote>\endhtmlonly
+ *
+ * <P>
+ * Once you've specified a locale you can query it for information about
+ * itself. Use <code>uloc_getCountry</code> to get the ISO Country Code and
+ * <code>uloc_getLanguage</code> to get the ISO Language Code. You can
+ * use <code>uloc_getDisplayCountry</code> to get the
+ * name of the country suitable for displaying to the user. Similarly,
+ * you can use <code>uloc_getDisplayLanguage</code> to get the name of
+ * the language suitable for displaying to the user. Interestingly,
+ * the <code>uloc_getDisplayXXX</code> methods are themselves locale-sensitive
+ * and have two versions: one that uses the default locale and one
+ * that takes a locale as an argument and displays the name or country in
+ * a language appropriate to that locale.
+ *
+ * <P>
+ * The ICU provides a number of services that perform locale-sensitive
+ * operations. For example, the <code>unum_xxx</code> functions format
+ * numbers, currency, or percentages in a locale-sensitive manner.
+ * </P>
+ * \htmlonly<blockquote>\endhtmlonly
+ * <pre>
+ * \code
+ * UErrorCode success = U_ZERO_ERROR;
+ * UNumberFormat *nf;
+ * const char* myLocale = "fr_FR";
+ *
+ * nf = unum_open( UNUM_DEFAULT, NULL, success );
+ * unum_close(nf);
+ * nf = unum_open( UNUM_CURRENCY, NULL, success );
+ * unum_close(nf);
+ * nf = unum_open( UNUM_PERCENT, NULL, success );
+ * unum_close(nf);
+ * \endcode
+ * </pre>
+ * \htmlonly</blockquote>\endhtmlonly
+ * Each of these methods has two variants; one with an explicit locale
+ * and one without; the latter using the default locale.
+ * \htmlonly<blockquote>\endhtmlonly
+ * <pre>
+ * \code
+ *
+ * nf = unum_open( UNUM_DEFAULT, myLocale, success );
+ * unum_close(nf);
+ * nf = unum_open( UNUM_CURRENCY, myLocale, success );
+ * unum_close(nf);
+ * nf = unum_open( UNUM_PERCENT, myLocale, success );
+ * unum_close(nf);
+ * \endcode
+ * </pre>
+ * \htmlonly</blockquote>\endhtmlonly
+ * A <code>Locale</code> is the mechanism for identifying the kind of services
+ * (<code>UNumberFormat</code>) that you would like to get. The locale is
+ * <STRONG>just</STRONG> a mechanism for identifying these services.
+ *
+ * <P>
+ * Each international serivce that performs locale-sensitive operations
+ * allows you
+ * to get all the available objects of that type. You can sift
+ * through these objects by language, country, or variant,
+ * and use the display names to present a menu to the user.
+ * For example, you can create a menu of all the collation objects
+ * suitable for a given language. Such classes implement these
+ * three class methods:
+ * \htmlonly<blockquote>\endhtmlonly
+ * <pre>
+ * \code
+ * const char* uloc_getAvailable(int32_t index);
+ * int32_t uloc_countAvailable();
+ * int32_t
+ * uloc_getDisplayName(const char* localeID,
+ * const char* inLocaleID,
+ * UChar* result,
+ * int32_t maxResultSize,
+ * UErrorCode* err);
+ *
+ * \endcode
+ * </pre>
+ * \htmlonly</blockquote>\endhtmlonly
+ * <P>
+ * Concerning POSIX/RFC1766 Locale IDs,
+ * the getLanguage/getCountry/getVariant/getName functions do understand
+ * the POSIX type form of language_COUNTRY.ENCODING\@VARIANT
+ * and if there is not an ICU-stype variant, uloc_getVariant() for example
+ * will return the one listed after the \@at sign. As well, the hyphen
+ * "-" is recognized as a country/variant separator similarly to RFC1766.
+ * So for example, "en-us" will be interpreted as en_US.
+ * As a result, uloc_getName() is far from a no-op, and will have the
+ * effect of converting POSIX/RFC1766 IDs into ICU form, although it does
+ * NOT map any of the actual codes (i.e. russian->ru) in any way.
+ * Applications should call uloc_getName() at the point where a locale ID
+ * is coming from an external source (user entry, OS, web browser)
+ * and pass the resulting string to other ICU functions. For example,
+ * don't use de-de\@EURO as an argument to resourcebundle.

- * <h2>Message Format C API </h2>
- *
- * Provides means to produce concatenated messages in language-neutral way.
- * Use this for all concatenations that show up to end users.
- * <P>
- * Takes a set of objects, formats them, then inserts the formatted
- * strings into the pattern at the appropriate places.
- * <P>
- * Here are some examples of usage:
- * Example 1:
- * <pre>
- * \code
- * UChar *result, *tzID, *str;
- * UChar pattern[100];
- * int32_t resultLengthOut, resultlength;
- * UCalendar *cal;
- * UDate d1;
- * UDateFormat *def1;
- * UErrorCode status = U_ZERO_ERROR;
- *
- * str=(UChar*)malloc(sizeof(UChar) * (strlen("disturbance in force") +1));
- * u_uastrcpy(str, "disturbance in force");
- * tzID=(UChar*)malloc(sizeof(UChar) * 4);
- * u_uastrcpy(tzID, "PST");
- * cal=ucal_open(tzID, u_strlen(tzID), "en_US", UCAL_TRADITIONAL, &status);
- * ucal_setDateTime(cal, 1999, UCAL_MARCH, 18, 0, 0, 0, &status);
- * d1=ucal_getMillis(cal, &status);
- * u_uastrcpy(pattern, "On {0, date, long}, there was a {1} on planet {2,number,integer}");
- * resultlength=0;
- * resultLengthOut=u_formatMessage( "en_US", pattern, u_strlen(pattern), NULL, resultlength, &status, d1, str, 7);
- * if(status==U_BUFFER_OVERFLOW_ERROR){
- * status=U_ZERO_ERROR;
- * resultlength=resultLengthOut+1;
- * result=(UChar*)realloc(result, sizeof(UChar) * resultlength);
- * u_formatMessage( "en_US", pattern, u_strlen(pattern), result, resultlength, &status, d1, str, 7);
- * }
- * printf("%s\n", austrdup(result) );//austrdup( a function used to convert UChar* to char*)
- * //output>: "On March 18, 1999, there was a disturbance in force on planet 7
- * \endcode
- * </pre>
- * Typically, the message format will come from resources, and the
- * arguments will be dynamically set at runtime.
- * <P>
- * Example 2:
- * <pre>
- * \code
- * UChar* str;
- * UErrorCode status = U_ZERO_ERROR;
- * UChar *result;
- * UChar pattern[100];
- * int32_t resultlength, resultLengthOut, i;
- * double testArgs= { 100.0, 1.0, 0.0};
- *
- * str=(UChar*)malloc(sizeof(UChar) * 10);
- * u_uastrcpy(str, "MyDisk");
- * u_uastrcpy(pattern, "The disk {1} contains {0,choice,0#no files|1#one file|1<{0,number,integer} files}");
- * for(i=0; i<3; i++){
- * resultlength=0;
- * resultLengthOut=u_formatMessage( "en_US", pattern, u_strlen(pattern), NULL, resultlength, &status, testArgs[i], str);
- * if(status==U_BUFFER_OVERFLOW_ERROR){
- * status=U_ZERO_ERROR;
- * resultlength=resultLengthOut+1;
- * result=(UChar*)malloc(sizeof(UChar) * resultlength);
- * u_formatMessage( "en_US", pattern, u_strlen(pattern), result, resultlength, &status, testArgs[i], str);
- * }
- * printf("%s\n", austrdup(result) ); //austrdup( a function used to convert UChar* to char*)
- * free(result);
- * }
- * // output, with different testArgs:
- * // output: The disk "MyDisk" contains 100 files.
- * // output: The disk "MyDisk" contains one file.
- * // output: The disk "MyDisk" contains no files.
- * \endcode
- * </pre>
- *
- * The pattern is of the following form. Legend:
- * <pre>
- * \code
- * {optional item}
- * (group that may be repeated)*
- * \endcode
- * </pre>
- * Do not confuse optional items with items inside quotes braces, such
- * as this: "{". Quoted braces are literals.
- * <pre>
- * \code
- * messageFormatPattern := string ( "{" messageFormatElement "}" string )*
- *
- * messageFormatElement := argument { "," elementFormat }
- *
- * elementFormat := "time" { "," datetimeStyle }
- * | "date" { "," datetimeStyle }
- * | "number" { "," numberStyle }
- * | "choice" "," choiceStyle
- *
- * datetimeStyle := "short"
- * | "medium"
- * | "long"
- * | "full"
- * | dateFormatPattern
- *
- * numberStyle := "currency"
- * | "percent"
- * | "integer"
- * | numberFormatPattern
- *
- * choiceStyle := choiceFormatPattern
- * \endcode
- * </pre>
- * If there is no elementFormat, then the argument must be a string,
- * which is substituted. If there is no dateTimeStyle or numberStyle,
- * then the default format is used (e.g. NumberFormat.getInstance(),
- * DateFormat.getDefaultTime() or DateFormat.getDefaultDate(). For
- * a ChoiceFormat, the pattern must always be specified, since there
- * is no default.
- * <P>
- * In strings, single quotes can be used to quote the "{" sign if
- * necessary. A real single quote is represented by ''. Inside a
- * messageFormatElement, quotes are [not] removed. For example,
- * {1,number,$'#',##} will produce a number format with the pound-sign
- * quoted, with a result such as: "$#31,45".
- * <P>
- * If a pattern is used, then unquoted braces in the pattern, if any,
- * must match: that is, "ab {0} de" and "ab '}' de" are ok, but "ab
- * {0'}' de" and "ab } de" are not.
- * <p>
- * <dl><dt><b>Warning:</b><dd>The rules for using quotes within message
- * format patterns unfortunately have shown to be somewhat confusing.
- * In particular, it isn't always obvious to localizers whether single
- * quotes need to be doubled or not. Make sure to inform localizers about
- * the rules, and tell them (for example, by using comments in resource
- * bundle source files) which strings will be processed by MessageFormat.
- * Note that localizers may need to use single quotes in translated
- * strings where the original version doesn't have them.
- * <br>Note also that the simplest way to avoid the problem is to
- * use the real apostrophe (single quote) character U+2019 (') for
- * human-readable text, and to use the ASCII apostrophe (U+0027 ' )
- * only in program syntax, like quoting in MessageFormat.
- * See the annotations for U+0027 Apostrophe in The Unicode Standard.</p>
- * </dl>
- * <P>
- * The argument is a number from 0 to 9, which corresponds to the
- * arguments presented in an array to be formatted.
- * <P>
- * It is ok to have unused arguments in the array. With missing
- * arguments or arguments that are not of the right class for the
- * specified format, a failing UErrorCode result is set.
- * <P>
-
- * <P>
- * [Note:] As we see above, the string produced by a choice Format in
- * MessageFormat is treated specially; occurances of '{' are used to
- * indicated subformats.
- * <P>
- * [Note:] Formats are numbered by order of variable in the string.
- * This is [not] the same as the argument numbering!
- * <pre>
- * \code
- * For example: with "abc{2}def{3}ghi{0}...",
- *
- * format0 affects the first variable {2}
- * format1 affects the second variable {3}
- * format2 affects the second variable {0}
- * \endcode
- * </pre>
- * and so on.

+ * // output: The disk "MyDisk" contains one file.
+ * // output: The disk "MyDisk" contains no files.
+ * \endcode
+ * </pre>
+ *
+ * The pattern is of the following form. Legend:
+ * <pre>
+ * \code
+ * {optional item}
+ * (group that may be repeated)*
+ * \endcode
+ * </pre>
+ * Do not confuse optional items with items inside quotes braces, such
+ * as this: "{". Quoted braces are literals.
+ * <pre>
+ * \code
+ * messageFormatPattern := string ( "{" messageFormatElement "}" string )*
+ *
+ * messageFormatElement := argument { "," elementFormat }
+ *
+ * elementFormat := "time" { "," datetimeStyle }
+ * | "date" { "," datetimeStyle }
+ * | "number" { "," numberStyle }
+ * | "choice" "," choiceStyle
+ *
+ * datetimeStyle := "short"
+ * | "medium"
+ * | "long"
+ * | "full"
+ * | dateFormatPattern
+ *
+ * numberStyle := "currency"
+ * | "percent"
+ * | "integer"
+ * | numberFormatPattern
+ *
+ * choiceStyle := choiceFormatPattern
+ * \endcode
+ * </pre>
+ * If there is no elementFormat, then the argument must be a string,
+ * which is substituted. If there is no dateTimeStyle or numberStyle,
+ * then the default format is used (e.g. NumberFormat.getInstance(),
+ * DateFormat.getDefaultTime() or DateFormat.getDefaultDate(). For
+ * a ChoiceFormat, the pattern must always be specified, since there
+ * is no default.
+ * <P>
+ * In strings, single quotes can be used to quote the "{" sign if
+ * necessary. A real single quote is represented by ''. Inside a
+ * messageFormatElement, quotes are [not] removed. For example,
+ * {1,number,$'#',##} will produce a number format with the pound-sign
+ * quoted, with a result such as: "$#31,45".
+ * <P>
+ * If a pattern is used, then unquoted braces in the pattern, if any,
+ * must match: that is, "ab {0} de" and "ab '}' de" are ok, but "ab
+ * {0'}' de" and "ab } de" are not.
+ * <p>
+ * <dl><dt><b>Warning:</b><dd>The rules for using quotes within message
+ * format patterns unfortunately have shown to be somewhat confusing.
+ * In particular, it isn't always obvious to localizers whether single
+ * quotes need to be doubled or not. Make sure to inform localizers about
+ * the rules, and tell them (for example, by using comments in resource
+ * bundle source files) which strings will be processed by MessageFormat.
+ * Note that localizers may need to use single quotes in translated
+ * strings where the original version doesn't have them.
+ * <br>Note also that the simplest way to avoid the problem is to
+ * use the real apostrophe (single quote) character U+2019 (') for
+ * human-readable text, and to use the ASCII apostrophe (U+0027 ' )
+ * only in program syntax, like quoting in MessageFormat.
+ * See the annotations for U+0027 Apostrophe in The Unicode Standard.</p>
+ * </dl>
+ * <P>
+ * The argument is a number from 0 to 9, which corresponds to the
+ * arguments presented in an array to be formatted.
+ * <P>
+ * It is ok to have unused arguments in the array. With missing
+ * arguments or arguments that are not of the right class for the
+ * specified format, a failing UErrorCode result is set.
+ * <P>
+
+ * <P>
+ * [Note:] As we see above, the string produced by a choice Format in
+ * MessageFormat is treated specially; occurances of '{' are used to
+ * indicated subformats.
+ * <P>
+ * [Note:] Formats are numbered by order of variable in the string.
+ * This is [not] the same as the argument numbering!
+ * <pre>
+ * \code
+ * For example: with "abc{2}def{3}ghi{0}...",
+ *
+ * format0 affects the first variable {2}
+ * format1 affects the second variable {3}
+ * format2 affects the second variable {0}

-/**
- * A mutable set of Unicode characters and multicharacter strings. Objects of this class
- * represent <em>character classes</em> used in regular expressions.
- * A character specifies a subset of Unicode code points. Legal
- * code points are U+0000 to U+10FFFF, inclusive.
- *
- * <p>The UnicodeSet class is not designed to be subclassed.
- *
- * <p><code>UnicodeSet</code> supports two APIs. The first is the
- * <em>operand</em> API that allows the caller to modify the value of
- * a <code>UnicodeSet</code> object. It conforms to Java 2's
- * <code>java.util.Set</code> interface, although
- * <code>UnicodeSet</code> does not actually implement that
- * interface. All methods of <code>Set</code> are supported, with the
- * modification that they take a character range or single character
- * instead of an <code>Object</code>, and they take a
- * <code>UnicodeSet</code> instead of a <code>Collection</code>. The
- * operand API may be thought of in terms of boolean logic: a boolean
- * OR is implemented by <code>add</code>, a boolean AND is implemented
- * by <code>retain</code>, a boolean XOR is implemented by
- * <code>complement</code> taking an argument, and a boolean NOT is
- * implemented by <code>complement</code> with no argument. In terms
- * of traditional set theory function names, <code>add</code> is a
- * union, <code>retain</code> is an intersection, <code>remove</code>
- * is an asymmetric difference, and <code>complement</code> with no
- * argument is a set complement with respect to the superset range
- * <code>MIN_VALUE-MAX_VALUE</code>
- *
- * <p>The second API is the
- * <code>applyPattern()</code>/<code>toPattern()</code> API from the
- * <code>java.text.Format</code>-derived classes. Unlike the
- * methods that add characters, add categories, and control the logic
- * of the set, the method <code>applyPattern()</code> sets all
- * attributes of a <code>UnicodeSet</code> at once, based on a
- * string pattern.
- *
- * <p><b>Pattern syntax</b></p>
- *
- * Patterns are accepted by the constructors and the
- * <code>applyPattern()</code> methods and returned by the
- * <code>toPattern()</code> method. These patterns follow a syntax
- * similar to that employed by version 8 regular expression character
- * classes. Here are some simple examples:
- *
- * \htmlonly<blockquote>\endhtmlonly
- * <table>
- * <tr align="top">
- * <td nowrap valign="top" align="left"><code>[]</code></td>
- * <td valign="top">No characters</td>
- * </tr><tr align="top">
- * <td nowrap valign="top" align="left"><code>[a]</code></td>
- * <td valign="top">The character 'a'</td>
- * </tr><tr align="top">
- * <td nowrap valign="top" align="left"><code>[ae]</code></td>
- * <td valign="top">The characters 'a' and 'e'</td>
- * </tr>
- * <tr>
- * <td nowrap valign="top" align="left"><code>[a-e]</code></td>
- * <td valign="top">The characters 'a' through 'e' inclusive, in Unicode code
- * point order</td>
- * </tr>
- * <tr>
- * <td nowrap valign="top" align="left"><code>[\\u4E01]</code></td>
- * <td valign="top">The character U+4E01</td>
- * </tr>
- * <tr>
- * <td nowrap valign="top" align="left"><code>[a{ab}{ac}]</code></td>
- * <td valign="top">The character 'a' and the multicharacter strings "ab" and
- * "ac"</td>
- * </tr>
- * <tr>
- * <td nowrap valign="top" align="left"><code>[\\p{Lu}]</code></td>
- * <td valign="top">All characters in the general category Uppercase Letter</td>
- * </tr>
- * </table>
- * \htmlonly</blockquote>\endhtmlonly
- *
- * Any character may be preceded by a backslash in order to remove any special
- * meaning. White space characters, as defined by UCharacter.isWhitespace(), are
- * ignored, unless they are escaped.
- *
- * <p>Property patterns specify a set of characters having a certain
- * property as defined by the Unicode standard. Both the POSIX-like
- * "[:Lu:]" and the Perl-like syntax "\\p{Lu}" are recognized. For a
- * complete list of supported property patterns, see the User's Guide
- * for UnicodeSet at
- * <a href="http://icu-project.org/userguide/unicodeSet.html">
- * http://icu-project.org/userguide/unicodeSet.html</a>.
- * Actual determination of property data is defined by the underlying
- * Unicode database as implemented by UCharacter.
- *
- * <p>Patterns specify individual characters, ranges of characters, and
- * Unicode property sets. When elements are concatenated, they
- * specify their union. To complement a set, place a '^' immediately
- * after the opening '['. Property patterns are inverted by modifying
- * their delimiters; "[:^foo]" and "\\P{foo}". In any other location,
- * '^' has no special meaning.
- *
- * <p>Ranges are indicated by placing two a '-' between two
- * characters, as in "a-z". This specifies the range of all
- * characters from the left to the right, in Unicode order. If the
- * left character is greater than or equal to the
- * right character it is a syntax error. If a '-' occurs as the first
- * character after the opening '[' or '[^', or if it occurs as the
- * last character before the closing ']', then it is taken as a
- * literal. Thus "[a\-b]", "[-ab]", and "[ab-]" all indicate the same
- * set of three characters, 'a', 'b', and '-'.
- *
- * <p>Sets may be intersected using the '&' operator or the asymmetric
- * set difference may be taken using the '-' operator, for example,
- * "[[:L:]&[\\u0000-\\u0FFF]]" indicates the set of all Unicode letters
- * with values less than 4096. Operators ('&' and '|') have equal
- * precedence and bind left-to-right. Thus
- * "[[:L:]-[a-z]-[\\u0100-\\u01FF]]" is equivalent to
- * "[[[:L:]-[a-z]]-[\\u0100-\\u01FF]]". This only really matters for
- * difference; intersection is commutative.
- *
- * <table>
- * <tr valign=top><td nowrap><code>[a]</code><td>The set containing 'a'
- * <tr valign=top><td nowrap><code>[a-z]</code><td>The set containing 'a'
- * through 'z' and all letters in between, in Unicode order
- * <tr valign=top><td nowrap><code>[^a-z]</code><td>The set containing

+/**
+ * A mutable set of Unicode characters and multicharacter strings. Objects of this class
+ * represent <em>character classes</em> used in regular expressions.
+ * A character specifies a subset of Unicode code points. Legal
+ * code points are U+0000 to U+10FFFF, inclusive.
+ *
+ * <p>The UnicodeSet class is not designed to be subclassed.
+ *
+ * <p><code>UnicodeSet</code> supports two APIs. The first is the
+ * <em>operand</em> API that allows the caller to modify the value of
+ * a <code>UnicodeSet</code> object. It conforms to Java 2's
+ * <code>java.util.Set</code> interface, although
+ * <code>UnicodeSet</code> does not actually implement that
+ * interface. All methods of <code>Set</code> are supported, with the
+ * modification that they take a character range or single character
+ * instead of an <code>Object</code>, and they take a
+ * <code>UnicodeSet</code> instead of a <code>Collection</code>. The
+ * operand API may be thought of in terms of boolean logic: a boolean
+ * OR is implemented by <code>add</code>, a boolean AND is implemented
+ * by <code>retain</code>, a boolean XOR is implemented by
+ * <code>complement</code> taking an argument, and a boolean NOT is
+ * implemented by <code>complement</code> with no argument. In terms
+ * of traditional set theory function names, <code>add</code> is a
+ * union, <code>retain</code> is an intersection, <code>remove</code>
+ * is an asymmetric difference, and <code>complement</code> with no
+ * argument is a set complement with respect to the superset range
+ * <code>MIN_VALUE-MAX_VALUE</code>
+ *
+ * <p>The second API is the
+ * <code>applyPattern()</code>/<code>toPattern()</code> API from the
+ * <code>java.text.Format</code>-derived classes. Unlike the
+ * methods that add characters, add categories, and control the logic
+ * of the set, the method <code>applyPattern()</code> sets all
+ * attributes of a <code>UnicodeSet</code> at once, based on a
+ * string pattern.
+ *
+ * <p><b>Pattern syntax</b></p>
+ *
+ * Patterns are accepted by the constructors and the
+ * <code>applyPattern()</code> methods and returned by the
+ * <code>toPattern()</code> method. These patterns follow a syntax
+ * similar to that employed by version 8 regular expression character
+ * classes. Here are some simple examples:
+ *
+ * \htmlonly<blockquote>\endhtmlonly
+ * <table>
+ * <tr align="top">
+ * <td nowrap valign="top" align="left"><code>[]</code></td>
+ * <td valign="top">No characters</td>
+ * </tr><tr align="top">
+ * <td nowrap valign="top" align="left"><code>[a]</code></td>
+ * <td valign="top">The character 'a'</td>
+ * </tr><tr align="top">
+ * <td nowrap valign="top" align="left"><code>[ae]</code></td>
+ * <td valign="top">The characters 'a' and 'e'</td>
+ * </tr>

+ * <td nowrap valign="top" align="left"><code>[a-e]</code></td>
+ * <td valign="top">The characters 'a' through 'e' inclusive, in Unicode code
+ * point order</td>
+ * </tr>
+ * <tr>
+ * <td nowrap valign="top" align="left"><code>[\\u4E01]</code></td>
+ * <td valign="top">The character U+4E01</td>
+ * </tr>
+ * <tr>
+ * <td nowrap valign="top" align="left"><code>[a{ab}{ac}]</code></td>
+ * <td valign="top">The character 'a' and the multicharacter strings "ab" and
+ * "ac"</td>
+ * </tr>
+ * <tr>
+ * <td nowrap valign="top" align="left"><code>[\\p{Lu}]</code></td>
+ * <td valign="top">All characters in the general category Uppercase Letter</td>
+ * </tr>
+ * </table>
+ * \htmlonly</blockquote>\endhtmlonly
+ *
+ * Any character may be preceded by a backslash in order to remove any special
+ * meaning. White space characters, as defined by UCharacter.isWhitespace(), are
+ * ignored, unless they are escaped.
+ *
+ * <p>Property patterns specify a set of characters having a certain
+ * property as defined by the Unicode standard. Both the POSIX-like
+ * "[:Lu:]" and the Perl-like syntax "\\p{Lu}" are recognized. For a
+ * complete list of supported property patterns, see the User's Guide
+ * for UnicodeSet at
+ * <a href="http://icu-project.org/userguide/unicodeSet.html">
+ * http://icu-project.org/userguide/unicodeSet.html</a>.
+ * Actual determination of property data is defined by the underlying
+ * Unicode database as implemented by UCharacter.
+ *
+ * <p>Patterns specify individual characters, ranges of characters, and
+ * Unicode property sets. When elements are concatenated, they
+ * specify their union. To complement a set, place a '^' immediately
+ * after the opening '['. Property patterns are inverted by modifying
+ * their delimiters; "[:^foo]" and "\\P{foo}". In any other location,
+ * '^' has no special meaning.
+ *
+ * <p>Ranges are indicated by placing two a '-' between two
+ * characters, as in "a-z". This specifies the range of all
+ * characters from the left to the right, in Unicode order. If the
+ * left character is greater than or equal to the
+ * right character it is a syntax error. If a '-' occurs as the first
+ * character after the opening '[' or '[^', or if it occurs as the
+ * last character before the closing ']', then it is taken as a
+ * literal. Thus "[a\-b]", "[-ab]", and "[ab-]" all indicate the same
+ * set of three characters, 'a', 'b', and '-'.
+ *
+ * <p>Sets may be intersected using the '&' operator or the asymmetric
+ * set difference may be taken using the '-' operator, for example,
+ * "[[:L:]&[\\u0000-\\u0FFF]]" indicates the set of all Unicode letters
+ * with values less than 4096. Operators ('&' and '|') have equal
+ * precedence and bind left-to-right. Thus
+ * "[[:L:]-[a-z]-[\\u0100-\\u01FF]]" is equivalent to
+ * "[[[:L:]-[a-z]]-[\\u0100-\\u01FF]]". This only really matters for
+ * difference; intersection is commutative.

-/**
- * UnicodeString is a string class that stores Unicode characters directly and provides
- * similar functionality as the Java String and StringBuffer classes.
- * It is a concrete implementation of the abstract class Replaceable (for transliteration).
- *
- * The UnicodeString class is not suitable for subclassing.
- *
- * <p>For an overview of Unicode strings in C and C++ see the
- * <a href="http://icu-project.org/userguide/strings.html">User Guide Strings chapter</a>.</p>
- *
- * <p>In ICU, a Unicode string consists of 16-bit Unicode <em>code units</em>.
- * A Unicode character may be stored with either one code unit
- * (the most common case) or with a matched pair of special code units
- * ("surrogates"). The data type for code units is UChar.
- * For single-character handling, a Unicode character code <em>point</em> is a value
- * in the range 0..0x10ffff. ICU uses the UChar32 type for code points.</p>
- *
- * <p>Indexes and offsets into and lengths of strings always count code units, not code points.
- * This is the same as with multi-byte char* strings in traditional string handling.
- * Operations on partial strings typically do not test for code point boundaries.
- * If necessary, the user needs to take care of such boundaries by testing for the code unit
- * values or by using functions like
- * UnicodeString::getChar32Start() and UnicodeString::getChar32Limit()
- * (or, in C, the equivalent macros U16_SET_CP_START() and U16_SET_CP_LIMIT(), see utf.h).</p>
- *
- * UnicodeString methods are more lenient with regard to input parameter values
- * than other ICU APIs. In particular:
- * - If indexes are out of bounds for a UnicodeString object
- * (<0 or >length()) then they are "pinned" to the nearest boundary.
- * - If primitive string pointer values (e.g., const UChar * or char *)
- * for input strings are NULL, then those input string parameters are treated
- * as if they pointed to an empty string.
- * However, this is <em>not</em> the case for char * parameters for charset names
- * or other IDs.
- * - Most UnicodeString methods do not take a UErrorCode parameter because
- * there are usually very few opportunities for failure other than a shortage
- * of memory, error codes in low-level C++ string methods would be inconvenient,
- * and the error code as the last parameter (ICU convention) would prevent
- * the use of default parameter values.
- * Instead, such methods set the UnicodeString into a "bogus" state
- * (see isBogus()) if an error occurs.
- *
- * In string comparisons, two UnicodeString objects that are both "bogus"
- * compare equal (to be transitive and prevent endless loops in sorting),
- * and a "bogus" string compares less than any non-"bogus" one.
- *
- * Const UnicodeString methods are thread-safe. Multiple threads can use
- * const methods on the same UnicodeString object simultaneously,
- * but non-const methods must not be called concurrently (in multiple threads)
- * with any other (const or non-const) methods.
- *
- * Similarly, const UnicodeString & parameters are thread-safe.
- * One object may be passed in as such a parameter concurrently in multiple threads.
- * This includes the const UnicodeString & parameters for
- * copy construction, assignment, and cloning.
- *
- * <p>UnicodeString uses several storage methods.
- * String contents can be stored inside the UnicodeString object itself,
- * in an allocated and shared buffer, or in an outside buffer that is "aliased".
- * Most of this is done transparently, but careful aliasing in particular provides
- * significant performance improvements.
- * Also, the internal buffer is accessible via special functions.
- * For details see the
- * <a href="http://icu-project.org/userguide/strings.html">User Guide Strings chapter</a>.</p>

+/**
+ * UnicodeString is a string class that stores Unicode characters directly and provides
+ * similar functionality as the Java String and StringBuffer classes.
+ * It is a concrete implementation of the abstract class Replaceable (for transliteration).
+ *
+ * The UnicodeString class is not suitable for subclassing.
+ *
+ * <p>For an overview of Unicode strings in C and C++ see the
+ * <a href="http://icu-project.org/userguide/strings.html">User Guide Strings chapter</a>.</p>
+ *
+ * <p>In ICU, a Unicode string consists of 16-bit Unicode <em>code units</em>.
+ * A Unicode character may be stored with either one code unit
+ * (the most common case) or with a matched pair of special code units
+ * ("surrogates"). The data type for code units is UChar.
+ * For single-character handling, a Unicode character code <em>point</em> is a value
+ * in the range 0..0x10ffff. ICU uses the UChar32 type for code points.</p>
+ *
+ * <p>Indexes and offsets into and lengths of strings always count code units, not code points.
+ * This is the same as with multi-byte char* strings in traditional string handling.
+ * Operations on partial strings typically do not test for code point boundaries.
+ * If necessary, the user needs to take care of such boundaries by testing for the code unit
+ * values or by using functions like
+ * UnicodeString::getChar32Start() and UnicodeString::getChar32Limit()
+ * (or, in C, the equivalent macros U16_SET_CP_START() and U16_SET_CP_LIMIT(), see utf.h).</p>
+ *
+ * UnicodeString methods are more lenient with regard to input parameter values
+ * than other ICU APIs. In particular:
+ * - If indexes are out of bounds for a UnicodeString object
+ * (<0 or >length()) then they are "pinned" to the nearest boundary.
+ * - If primitive string pointer values (e.g., const UChar * or char *)
+ * for input strings are NULL, then those input string parameters are treated
+ * as if they pointed to an empty string.
+ * However, this is <em>not</em> the case for char * parameters for charset names
+ * or other IDs.
+ * - Most UnicodeString methods do not take a UErrorCode parameter because
+ * there are usually very few opportunities for failure other than a shortage
+ * of memory, error codes in low-level C++ string methods would be inconvenient,
+ * and the error code as the last parameter (ICU convention) would prevent
+ * the use of default parameter values.
+ * Instead, such methods set the UnicodeString into a "bogus" state
+ * (see isBogus()) if an error occurs.
+ *
+ * In string comparisons, two UnicodeString objects that are both "bogus"
+ * compare equal (to be transitive and prevent endless loops in sorting),
+ * and a "bogus" string compares less than any non-"bogus" one.
+ *
+ * Const UnicodeString methods are thread-safe. Multiple threads can use
+ * const methods on the same UnicodeString object simultaneously,
+ * but non-const methods must not be called concurrently (in multiple threads)
+ * with any other (const or non-const) methods.
+ *
+ * Similarly, const UnicodeString & parameters are thread-safe.
+ * One object may be passed in as such a parameter concurrently in multiple threads.
+ * This includes the const UnicodeString & parameters for
+ * copy construction, assignment, and cloning.
+ *
+ * <p>UnicodeString uses several storage methods.
+ * String contents can be stored inside the UnicodeString object itself,
+ * in an allocated and shared buffer, or in an outside buffer that is "aliased".
+ * Most of this is done transparently, but careful aliasing in particular provides
+ * significant performance improvements.
+ * Also, the internal buffer is accessible via special functions.
+ * For details see the
+ * <a href="http://icu-project.org/userguide/strings.html">User Guide Strings chapter</a>.</p>

- * \file
- * \brief C API: Unicode Normalization
- *
- * <h2>Unicode normalization API</h2>
- *
- * <code>unorm_normalize</code> transforms Unicode text into an equivalent composed or
- * decomposed form, allowing for easier sorting and searching of text.
- * <code>unorm_normalize</code> supports the standard normalization forms described in
- * <a href="http://www.unicode.org/unicode/reports/tr15/" target="unicode">
- * Unicode Standard Annex #15: Unicode Normalization Forms</a>.
- *
- * Characters with accents or other adornments can be encoded in
- * several different ways in Unicode. For example, take the character A-acute.
- * In Unicode, this can be encoded as a single character (the
- * "composed" form):
- *
- * \code
- * 00C1 LATIN CAPITAL LETTER A WITH ACUTE
- * \endcode
- *
- * or as two separate characters (the "decomposed" form):
- *
- * \code
- * 0041 LATIN CAPITAL LETTER A
- * 0301 COMBINING ACUTE ACCENT
- * \endcode
- *
- * To a user of your program, however, both of these sequences should be
- * treated as the same "user-level" character "A with acute accent". When you are searching or
- * comparing text, you must ensure that these two sequences are treated
- * equivalently. In addition, you must handle characters with more than one
- * accent. Sometimes the order of a character's combining accents is
- * significant, while in other cases accent sequences in different orders are
- * really equivalent.
- *
- * Similarly, the string "ffi" can be encoded as three separate letters:
- *
- * \code
- * 0066 LATIN SMALL LETTER F
- * 0066 LATIN SMALL LETTER F
- * 0069 LATIN SMALL LETTER I
- * \endcode
- *
- * or as the single character
- *
- * \code
- * FB03 LATIN SMALL LIGATURE FFI
- * \endcode
- *
- * The ffi ligature is not a distinct semantic character, and strictly speaking
- * it shouldn't be in Unicode at all, but it was included for compatibility
- * with existing character sets that already provided it. The Unicode standard
- * identifies such characters by giving them "compatibility" decompositions
- * into the corresponding semantic characters. When sorting and searching, you
- * will often want to use these mappings.
- *
- * <code>unorm_normalize</code> helps solve these problems by transforming text into the
- * canonical composed and decomposed forms as shown in the first example above.
- * In addition, you can have it perform compatibility decompositions so that
- * you can treat compatibility characters the same as their equivalents.
- * Finally, <code>unorm_normalize</code> rearranges accents into the proper canonical
- * order, so that you do not have to worry about accent rearrangement on your
- * own.
- *
- * Form FCD, "Fast C or D", is also designed for collation.
- * It allows to work on strings that are not necessarily normalized
- * with an algorithm (like in collation) that works under "canonical closure", i.e., it treats precomposed
- * characters and their decomposed equivalents the same.
- *
- * It is not a normalization form because it does not provide for uniqueness of representation. Multiple strings
- * may be canonically equivalent (their NFDs are identical) and may all conform to FCD without being identical
- * themselves.
- *
- * The form is defined such that the "raw decomposition", the recursive canonical decomposition of each character,
- * results in a string that is canonically ordered. This means that precomposed characters are allowed for as long
- * as their decompositions do not need canonical reordering.
- *
- * Its advantage for a process like collation is that all NFD and most NFC texts - and many unnormalized texts -
- * already conform to FCD and do not need to be normalized (NFD) for such a process. The FCD quick check will
- * return UNORM_YES for most strings in practice.
- *
- * unorm_normalize(UNORM_FCD) may be implemented with UNORM_NFD.
- *
- * For more details on FCD see the collation design document:
- * http://source.icu-project.org/repos/icu/icuhtml/trunk/design/collation/ICU_collation_design.htm
- *
- * ICU collation performs either NFD or FCD normalization automatically if normalization
- * is turned on for the collator object.
- * Beyond collation and string search, normalized strings may be useful for string equivalence comparisons,
- * transliteration/transcription, unique representations, etc.
- *
- * The W3C generally recommends to exchange texts in NFC.
- * Note also that most legacy character encodings use only precomposed forms and often do not
- * encode any combining marks by themselves. For conversion to such character encodings the
- * Unicode text needs to be normalized to NFC.
- * For more usage examples, see the Unicode Standard Annex.

-/**
- * Iterative normalization forward.
- * This function (together with unorm_previous) is somewhat
- * similar to the C++ Normalizer class (see its non-static functions).
- *
- * Iterative normalization is useful when only a small portion of a longer
- * string/text needs to be processed.
- *
- * For example, the likelihood may be high that processing the first 10% of some
- * text will be sufficient to find certain data.
- * Another example: When one wants to concatenate two normalized strings and get a
- * normalized result, it is much more efficient to normalize just a small part of
- * the result around the concatenation place instead of re-normalizing everything.
- *
- * The input text is an instance of the C character iteration API UCharIterator.
- * It may wrap around a simple string, a CharacterIterator, a Replaceable, or any
- * other kind of text object.
- *
- * If a buffer overflow occurs, then the caller needs to reset the iterator to the
- * old index and call the function again with a larger buffer - if the caller cares
- * for the actual output.
- * Regardless of the output buffer, the iterator will always be moved to the next
- * normalization boundary.
- *
- * This function (like unorm_previous) serves two purposes:
- *
- * 1) To find the next boundary so that the normalization of the part of the text
- * from the current position to that boundary does not affect and is not affected
- * by the part of the text beyond that boundary.
- *
- * 2) To normalize the text up to the boundary.
- *
- * The second step is optional, per the doNormalize parameter.
- * It is omitted for operations like string concatenation, where the two adjacent
- * string ends need to be normalized together.
- * In such a case, the output buffer will just contain a copy of the text up to the
- * boundary.
- *
- * pNeededToNormalize is an output-only parameter. Its output value is only defined
- * if normalization was requested (doNormalize) and successful (especially, no
- * buffer overflow).
- * It is useful for operations like a normalizing transliterator, where one would
- * not want to replace a piece of text if it is not modified.
- *
- * If doNormalize==TRUE and pNeededToNormalize!=NULL then *pNeeded... is set TRUE
- * if the normalization was necessary.
- *
- * If doNormalize==FALSE then *pNeededToNormalize will be set to FALSE.
- *
- * If the buffer overflows, then *pNeededToNormalize will be undefined;
- * essentially, whenever U_FAILURE is true (like in buffer overflows), this result
- * will be undefined.
- *
- * @param src The input text in the form of a C character iterator.
- * @param dest The output buffer; can be NULL if destCapacity==0 for pure preflighting.
- * @param destCapacity The number of UChars that fit into dest.
- * @param mode The normalization mode.
- * @param options The normalization options, ORed together (0 for no options).
- * @param doNormalize Indicates if the source text up to the next boundary
- * is to be normalized (TRUE) or just copied (FALSE).

- * different text from the input.

+ * \file
+ * \brief C API: Unicode Normalization
+ *
+ * <h2>Unicode normalization API</h2>
+ *
+ * <code>unorm_normalize</code> transforms Unicode text into an equivalent composed or
+ * decomposed form, allowing for easier sorting and searching of text.
+ * <code>unorm_normalize</code> supports the standard normalization forms described in
+ * <a href="http://www.unicode.org/unicode/reports/tr15/" target="unicode">
+ * Unicode Standard Annex #15: Unicode Normalization Forms</a>.
+ *
+ * Characters with accents or other adornments can be encoded in
+ * several different ways in Unicode. For example, take the character A-acute.
+ * In Unicode, this can be encoded as a single character (the
+ * "composed" form):
+ *
+ * \code
+ * 00C1 LATIN CAPITAL LETTER A WITH ACUTE
+ * \endcode
+ *
+ * or as two separate characters (the "decomposed" form):
+ *
+ * \code
+ * 0041 LATIN CAPITAL LETTER A
+ * 0301 COMBINING ACUTE ACCENT
+ * \endcode
+ *
+ * To a user of your program, however, both of these sequences should be
+ * treated as the same "user-level" character "A with acute accent". When you are searching or
+ * comparing text, you must ensure that these two sequences are treated
+ * equivalently. In addition, you must handle characters with more than one
+ * accent. Sometimes the order of a character's combining accents is
+ * significant, while in other cases accent sequences in different orders are
+ * really equivalent.
+ *
+ * Similarly, the string "ffi" can be encoded as three separate letters:
+ *
+ * \code
+ * 0066 LATIN SMALL LETTER F
+ * 0066 LATIN SMALL LETTER F
+ * 0069 LATIN SMALL LETTER I
+ * \endcode
+ *
+ * or as the single character
+ *
+ * \code
+ * FB03 LATIN SMALL LIGATURE FFI
+ * \endcode
+ *
+ * The ffi ligature is not a distinct semantic character, and strictly speaking
+ * it shouldn't be in Unicode at all, but it was included for compatibility
+ * with existing character sets that already provided it. The Unicode standard
+ * identifies such characters by giving them "compatibility" decompositions
+ * into the corresponding semantic characters. When sorting and searching, you
+ * will often want to use these mappings.
+ *
+ * <code>unorm_normalize</code> helps solve these problems by transforming text into the
+ * canonical composed and decomposed forms as shown in the first example above.
+ * In addition, you can have it perform compatibility decompositions so that
+ * you can treat compatibility characters the same as their equivalents.
+ * Finally, <code>unorm_normalize</code> rearranges accents into the proper canonical
+ * order, so that you do not have to worry about accent rearrangement on your
+ * own.
+ *
+ * Form FCD, "Fast C or D", is also designed for collation.
+ * It allows to work on strings that are not necessarily normalized
+ * with an algorithm (like in collation) that works under "canonical closure", i.e., it treats precomposed
+ * characters and their decomposed equivalents the same.
+ *
+ * It is not a normalization form because it does not provide for uniqueness of representation. Multiple strings
+ * may be canonically equivalent (their NFDs are identical) and may all conform to FCD without being identical
+ * themselves.
+ *
+ * The form is defined such that the "raw decomposition", the recursive canonical decomposition of each character,
+ * results in a string that is canonically ordered. This means that precomposed characters are allowed for as long
+ * as their decompositions do not need canonical reordering.
+ *
+ * Its advantage for a process like collation is that all NFD and most NFC texts - and many unnormalized texts -
+ * already conform to FCD and do not need to be normalized (NFD) for such a process. The FCD quick check will
+ * return UNORM_YES for most strings in practice.
+ *
+ * unorm_normalize(UNORM_FCD) may be implemented with UNORM_NFD.
+ *
+ * For more details on FCD see the collation design document:
+ * http://source.icu-project.org/repos/icu/icuhtml/trunk/design/collation/ICU_collation_design.htm
+ *
+ * ICU collation performs either NFD or FCD normalization automatically if normalization
+ * is turned on for the collator object.
+ * Beyond collation and string search, normalized strings may be useful for string equivalence comparisons,
+ * transliteration/transcription, unique representations, etc.
+ *
+ * The W3C generally recommends to exchange texts in NFC.
+ * Note also that most legacy character encodings use only precomposed forms and often do not
+ * encode any combining marks by themselves. For conversion to such character encodings the
+ * Unicode text needs to be normalized to NFC.
+ * For more usage examples, see the Unicode Standard Annex.

+/**
+ * Iterative normalization forward.
+ * This function (together with unorm_previous) is somewhat
+ * similar to the C++ Normalizer class (see its non-static functions).
+ *
+ * Iterative normalization is useful when only a small portion of a longer
+ * string/text needs to be processed.
+ *
+ * For example, the likelihood may be high that processing the first 10% of some
+ * text will be sufficient to find certain data.
+ * Another example: When one wants to concatenate two normalized strings and get a
+ * normalized result, it is much more efficient to normalize just a small part of
+ * the result around the concatenation place instead of re-normalizing everything.
+ *
+ * The input text is an instance of the C character iteration API UCharIterator.
+ * It may wrap around a simple string, a CharacterIterator, a Replaceable, or any
+ * other kind of text object.
+ *
+ * If a buffer overflow occurs, then the caller needs to reset the iterator to the
+ * old index and call the function again with a larger buffer - if the caller cares
+ * for the actual output.
+ * Regardless of the output buffer, the iterator will always be moved to the next
+ * normalization boundary.
+ *
+ * This function (like unorm_previous) serves two purposes:
+ *
+ * 1) To find the next boundary so that the normalization of the part of the text
+ * from the current position to that boundary does not affect and is not affected
+ * by the part of the text beyond that boundary.
+ *
+ * 2) To normalize the text up to the boundary.
+ *
+ * The second step is optional, per the doNormalize parameter.
+ * It is omitted for operations like string concatenation, where the two adjacent
+ * string ends need to be normalized together.
+ * In such a case, the output buffer will just contain a copy of the text up to the
+ * boundary.
+ *
+ * pNeededToNormalize is an output-only parameter. Its output value is only defined
+ * if normalization was requested (doNormalize) and successful (especially, no
+ * buffer overflow).
+ * It is useful for operations like a normalizing transliterator, where one would
+ * not want to replace a piece of text if it is not modified.
+ *
+ * If doNormalize==TRUE and pNeededToNormalize!=NULL then *pNeeded... is set TRUE
+ * if the normalization was necessary.
+ *
+ * If doNormalize==FALSE then *pNeededToNormalize will be set to FALSE.
+ *
+ * If the buffer overflows, then *pNeededToNormalize will be undefined;
+ * essentially, whenever U_FAILURE is true (like in buffer overflows), this result
+ * will be undefined.
+ *
+ * @param src The input text in the form of a C character iterator.
+ * @param dest The output buffer; can be NULL if destCapacity==0 for pure preflighting.
+ * @param destCapacity The number of UChars that fit into dest.
+ * @param mode The normalization mode.

- *
- * <h2> Number Format C API </h2>
- *
- * Number Format C API Provides functions for
- * formatting and parsing a number. Also provides methods for
- * determining which locales have number formats, and what their names
- * are.
- * <P>
- * UNumberFormat helps you to format and parse numbers for any locale.
- * Your code can be completely independent of the locale conventions
- * for decimal points, thousands-separators, or even the particular
- * decimal digits used, or whether the number format is even decimal.
- * There are different number format styles like decimal, currency,
- * percent and spellout.
- * <P>
- * To format a number for the current Locale, use one of the static
- * factory methods:
- * <pre>
- * \code
- * UChar myString[20];
- * double myNumber = 7.0;
- * UErrorCode status = U_ZERO_ERROR;
- * UNumberFormat* nf = unum_open(UNUM_DEFAULT, NULL, -1, NULL, NULL, &status);
- * unum_formatDouble(nf, myNumber, myString, 20, NULL, &status);
- * printf(" Example 1: %s\n", austrdup(myString) ); //austrdup( a function used to convert UChar* to char*)
- * \endcode
- * </pre>
- * If you are formatting multiple numbers, it is more efficient to get
- * the format and use it multiple times so that the system doesn't
- * have to fetch the information about the local language and country
- * conventions multiple times.
- * <pre>
- * \code
- * uint32_t i, resultlength, reslenneeded;
- * UErrorCode status = U_ZERO_ERROR;
- * UFieldPosition pos;
- * uint32_t a[] = { 123, 3333, -1234567 };
- * const uint32_t a_len = sizeof(a) / sizeof(a[0]);
- * UNumberFormat* nf;
- * UChar* result = NULL;
- *
- * nf = unum_open(UNUM_DEFAULT, NULL, -1, NULL, NULL, &status);
- * for (i = 0; i < a_len; i++) {

- * <P>
- * You can also control the display of numbers with such function as
- * unum_getAttribues() and unum_setAtributes(), which let you set the
- * miminum fraction digits, grouping, etc.
- * @see UNumberFormatAttributes for more details
- * <P>
- * You can also use forms of the parse and format methods with

- * <ul type=round>
- * <li>(a) progressively parse through pieces of a string.
- * <li>(b) align the decimal point and other areas.
- * </ul>
- * <p>
- * It is also possible to change or set the symbols used for a particular
- * locale like the currency symbol, the grouping seperator , monetary seperator
- * etc by making use of functions unum_setSymbols() and unum_getSymbols().

+ * \file
+ * \brief C API: NumberFormat
+ *
+ * <h2> Number Format C API </h2>
+ *
+ * Number Format C API Provides functions for
+ * formatting and parsing a number. Also provides methods for
+ * determining which locales have number formats, and what their names
+ * are.
+ * <P>
+ * UNumberFormat helps you to format and parse numbers for any locale.
+ * Your code can be completely independent of the locale conventions
+ * for decimal points, thousands-separators, or even the particular
+ * decimal digits used, or whether the number format is even decimal.
+ * There are different number format styles like decimal, currency,
+ * percent and spellout.
+ * <P>
+ * To format a number for the current Locale, use one of the static
+ * factory methods:
+ * <pre>
+ * \code
+ * UChar myString[20];
+ * double myNumber = 7.0;
+ * UErrorCode status = U_ZERO_ERROR;
+ * UNumberFormat* nf = unum_open(UNUM_DEFAULT, NULL, -1, NULL, NULL, &status);
+ * unum_formatDouble(nf, myNumber, myString, 20, NULL, &status);
+ * printf(" Example 1: %s\n", austrdup(myString) ); //austrdup( a function used to convert UChar* to char*)
+ * \endcode
+ * </pre>
+ * If you are formatting multiple numbers, it is more efficient to get
+ * the format and use it multiple times so that the system doesn't
+ * have to fetch the information about the local language and country
+ * conventions multiple times.
+ * <pre>
+ * \code
+ * uint32_t i, resultlength, reslenneeded;
+ * UErrorCode status = U_ZERO_ERROR;
+ * UFieldPosition pos;
+ * uint32_t a[] = { 123, 3333, -1234567 };
+ * const uint32_t a_len = sizeof(a) / sizeof(a[0]);
+ * UNumberFormat* nf;
+ * UChar* result = NULL;
+ *
+ * nf = unum_open(UNUM_DEFAULT, NULL, -1, NULL, NULL, &status);
+ * for (i = 0; i < a_len; i++) {
+ * resultlength=0;
+ * reslenneeded=unum_format(nf, a[i], NULL, resultlength, &pos, &status);
+ * result = NULL;
+ * if(status==U_BUFFER_OVERFLOW_ERROR){
+ * status=U_ZERO_ERROR;
+ * resultlength=reslenneeded+1;
+ * result=(UChar*)malloc(sizeof(UChar) * resultlength);
+ * unum_format(nf, a[i], result, resultlength, &pos, &status);
+ * }
+ * printf( " Example 2: %s\n", austrdup(result));
+ * free(result);
+ * }
+ * \endcode
+ * </pre>
+ * To format a number for a different Locale, specify it in the
+ * call to unum_open().
+ * <pre>
+ * \code
+ * UNumberFormat* nf = unum_open(UNUM_DEFAULT, NULL, -1, "fr_FR", NULL, &success)
+ * \endcode
+ * </pre>
+ * You can use a NumberFormat API unum_parse() to parse.
+ * <pre>
+ * \code
+ * UErrorCode status = U_ZERO_ERROR;
+ * int32_t pos=0;
+ * int32_t num;
+ * num = unum_parse(nf, str, u_strlen(str), &pos, &status);
+ * \endcode
+ * </pre>
+ * Use UNUM_DECIMAL to get the normal number format for that country.
+ * There are other static options available. Use UNUM_CURRENCY
+ * to get the currency number format for that country. Use UNUM_PERCENT
+ * to get a format for displaying percentages. With this format, a
+ * fraction from 0.53 is displayed as 53%.
+ * <P>
+ * Use a pattern to create either a DecimalFormat or a RuleBasedNumberFormat
+ * formatter. The pattern must conform to the syntax defined for those
+ * formatters.
+ * <P>
+ * You can also control the display of numbers with such function as
+ * unum_getAttribues() and unum_setAtributes(), which let you set the
+ * miminum fraction digits, grouping, etc.
+ * @see UNumberFormatAttributes for more details
+ * <P>
+ * You can also use forms of the parse and format methods with
+ * ParsePosition and UFieldPosition to allow you to:
+ * <ul type=round>
+ * <li>(a) progressively parse through pieces of a string.
+ * <li>(b) align the decimal point and other areas.
+ * </ul>
+ * <p>
+ * It is also possible to change or set the symbols used for a particular
+ * locale like the currency symbol, the grouping seperator , monetary seperator
+ * etc by making use of functions unum_setSymbols() and unum_getSymbols().

-/**
- * \file
- * \brief C API: StringSearch
- *
- * C Apis for an engine that provides language-sensitive text searching based
- * on the comparison rules defined in a <tt>UCollator</tt> data struct,
- * see <tt>ucol.h</tt>. This ensures that language eccentricity can be
- * handled, e.g. for the German collator, characters ß and SS will be matched
- * if case is chosen to be ignored.
- * See the <a href="http://source.icu-project.org/repos/icu/icuhtml/trunk/design/collation/ICU_collation_design.htm">
- * "ICU Collation Design Document"</a> for more information.
- * <p>
- * The algorithm implemented is a modified form of the Boyer Moore's search.
- * For more information see
- * <a href="http://icu-project.org/docs/papers/efficient_text_searching_in_java.html">
- * "Efficient Text Searching in Java"</a>, published in <i>Java Report</i>
- * in February, 1999, for further information on the algorithm.
- * <p>
- * There are 2 match options for selection:<br>
- * Let S' be the sub-string of a text string S between the offsets start and
- * end <start, end>.
- * <br>
- * A pattern string P matches a text string S at the offsets <start, end>
- * if
- * <pre>
- * option 1. Some canonical equivalent of P matches some canonical equivalent
- * of S'
- * option 2. P matches S' and if P starts or ends with a combining mark,
- * there exists no non-ignorable combining mark before or after S'
- * in S respectively.
- * </pre>
- * Option 2. will be the default.
- * <p>
- * This search has APIs similar to that of other text iteration mechanisms
- * such as the break iterators in <tt>ubrk.h</tt>. Using these
- * APIs, it is easy to scan through text looking for all occurances of
- * a given pattern. This search iterator allows changing of direction by
- * calling a <tt>reset</tt> followed by a <tt>next</tt> or <tt>previous</tt>.
- * Though a direction change can occur without calling <tt>reset</tt> first,
- * this operation comes with some speed penalty.
- * Generally, match results in the forward direction will match the result
- * matches in the backwards direction in the reverse order
- * <p>
- * <tt>usearch.h</tt> provides APIs to specify the starting position
- * within the text string to be searched, e.g. <tt>usearch_setOffset</tt>,
- * <tt>usearch_preceding</tt> and <tt>usearch_following</tt>. Since the
- * starting position will be set as it is specified, please take note that
- * there are some dangerous positions which the search may render incorrect
- * results:
- * <ul>
- * <li> The midst of a substring that requires normalization.
- * <li> If the following match is to be found, the position should not be the
- * second character which requires to be swapped with the preceding
- * character. Vice versa, if the preceding match is to be found,
- * position to search from should not be the first character which
- * requires to be swapped with the next character. E.g certain Thai and
- * Lao characters require swapping.
- * <li> If a following pattern match is to be found, any position within a
- * contracting sequence except the first will fail. Vice versa if a
- * preceding pattern match is to be found, a invalid starting point
- * would be any character within a contracting sequence except the last.
- * </ul>
- * <p>
- * A breakiterator can be used if only matches at logical breaks are desired.
- * Using a breakiterator will only give you results that exactly matches the
- * boundaries given by the breakiterator. For instance the pattern "e" will
- * not be found in the string "\u00e9" if a character break iterator is used.
- * <p>
- * Options are provided to handle overlapping matches.
- * E.g. In English, overlapping matches produces the result 0 and 2
- * for the pattern "abab" in the text "ababab", where else mutually
- * exclusive matches only produce the result of 0.
- * <p>
- * Though collator attributes will be taken into consideration while
- * performing matches, there are no APIs here for setting and getting the
- * attributes. These attributes can be set by getting the collator
- * from <tt>usearch_getCollator</tt> and using the APIs in <tt>ucol.h</tt>.
- * Lastly to update String Search to the new collator attributes,
- * usearch_reset() has to be called.
- * <p>
- * Restriction: <br>
- * Currently there are no composite characters that consists of a
- * character with combining class > 0 before a character with combining
- * class == 0. However, if such a character exists in the future, the
- * search mechanism does not guarantee the results for option 1.
- *
- * <p>
- * Example of use:<br>
- * <pre><code>
- * char *tgtstr = "The quick brown fox jumped over the lazy fox";
- * char *patstr = "fox";
- * UChar target[64];
- * UChar pattern[16];
- * UErrorCode status = U_ZERO_ERROR;
- * u_uastrcpy(target, tgtstr);
- * u_uastrcpy(pattern, patstr);
- *
- * UStringSearch *search = usearch_open(pattern, -1, target, -1, "en_US",
- * NULL, &status);
- * if (U_SUCCESS(status)) {
- * for (int pos = usearch_first(search, &status);
- * pos != USEARCH_DONE;
- * pos = usearch_next(search, &status))
- * {
- * printf("Found match at %d pos, length is %d\n", pos,
- * usearch_getMatchLength(search));
- * }
- * }
- *
- * usearch_close(search);
- * </code></pre>

+/**
+ * \file
+ * \brief C API: StringSearch
+ *
+ * C Apis for an engine that provides language-sensitive text searching based
+ * on the comparison rules defined in a <tt>UCollator</tt> data struct,
+ * see <tt>ucol.h</tt>. This ensures that language eccentricity can be
+ * handled, e.g. for the German collator, characters ß and SS will be matched
+ * if case is chosen to be ignored.
+ * See the <a href="http://source.icu-project.org/repos/icu/icuhtml/trunk/design/collation/ICU_collation_design.htm">
+ * "ICU Collation Design Document"</a> for more information.
+ * <p>
+ * The algorithm implemented is a modified form of the Boyer Moore's search.
+ * For more information see
+ * <a href="http://icu-project.org/docs/papers/efficient_text_searching_in_java.html">
+ * "Efficient Text Searching in Java"</a>, published in <i>Java Report</i>
+ * in February, 1999, for further information on the algorithm.
+ * <p>
+ * There are 2 match options for selection:<br>
+ * Let S' be the sub-string of a text string S between the offsets start and
+ * end <start, end>.
+ * <br>
+ * A pattern string P matches a text string S at the offsets <start, end>
+ * if
+ * <pre>
+ * option 1. Some canonical equivalent of P matches some canonical equivalent
+ * of S'
+ * option 2. P matches S' and if P starts or ends with a combining mark,
+ * there exists no non-ignorable combining mark before or after S'
+ * in S respectively.
+ * </pre>
+ * Option 2. will be the default.
+ * <p>
+ * This search has APIs similar to that of other text iteration mechanisms
+ * such as the break iterators in <tt>ubrk.h</tt>. Using these
+ * APIs, it is easy to scan through text looking for all occurances of
+ * a given pattern. This search iterator allows changing of direction by
+ * calling a <tt>reset</tt> followed by a <tt>next</tt> or <tt>previous</tt>.
+ * Though a direction change can occur without calling <tt>reset</tt> first,
+ * this operation comes with some speed penalty.
+ * Generally, match results in the forward direction will match the result
+ * matches in the backwards direction in the reverse order
+ * <p>
+ * <tt>usearch.h</tt> provides APIs to specify the starting position
+ * within the text string to be searched, e.g. <tt>usearch_setOffset</tt>,
+ * <tt>usearch_preceding</tt> and <tt>usearch_following</tt>. Since the
+ * starting position will be set as it is specified, please take note that
+ * there are some dangerous positions which the search may render incorrect
+ * results:
+ * <ul>
+ * <li> The midst of a substring that requires normalization.
+ * <li> If the following match is to be found, the position should not be the
+ * second character which requires to be swapped with the preceding
+ * character. Vice versa, if the preceding match is to be found,
+ * position to search from should not be the first character which
+ * requires to be swapped with the next character. E.g certain Thai and
+ * Lao characters require swapping.
+ * <li> If a following pattern match is to be found, any position within a
+ * contracting sequence except the first will fail. Vice versa if a
+ * preceding pattern match is to be found, a invalid starting point
+ * would be any character within a contracting sequence except the last.
+ * </ul>
+ * <p>
+ * A breakiterator can be used if only matches at logical breaks are desired.
+ * Using a breakiterator will only give you results that exactly matches the
+ * boundaries given by the breakiterator. For instance the pattern "e" will
+ * not be found in the string "\u00e9" if a character break iterator is used.
+ * <p>
+ * Options are provided to handle overlapping matches.
+ * E.g. In English, overlapping matches produces the result 0 and 2
+ * for the pattern "abab" in the text "ababab", where else mutually
+ * exclusive matches only produce the result of 0.
+ * <p>
+ * Though collator attributes will be taken into consideration while
+ * performing matches, there are no APIs here for setting and getting the
+ * attributes. These attributes can be set by getting the collator
+ * from <tt>usearch_getCollator</tt> and using the APIs in <tt>ucol.h</tt>.
+ * Lastly to update String Search to the new collator attributes,
+ * usearch_reset() has to be called.
+ * <p>
+ * Restriction: <br>
+ * Currently there are no composite characters that consists of a
+ * character with combining class > 0 before a character with combining
+ * class == 0. However, if such a character exists in the future, the
+ * search mechanism does not guarantee the results for option 1.
+ *
+ * <p>
+ * Example of use:<br>
+ * <pre><code>
+ * char *tgtstr = "The quick brown fox jumped over the lazy fox";
+ * char *patstr = "fox";
+ * UChar target[64];
+ * UChar pattern[16];
+ * UErrorCode status = U_ZERO_ERROR;
+ * u_uastrcpy(target, tgtstr);
+ * u_uastrcpy(pattern, patstr);
+ *
+ * UStringSearch *search = usearch_open(pattern, -1, target, -1, "en_US",
+ * NULL, &status);
+ * if (U_SUCCESS(status)) {
+ * for (int pos = usearch_first(search, &status);
+ * pos != USEARCH_DONE;
+ * pos = usearch_next(search, &status))
+ * {
+ * printf("Found match at %d pos, length is %d\n", pos,
+ * usearch_getMatchLength(search));
+ * }
+ * }
+ *
+ * usearch_close(search);
+ * </code></pre>

- * Argument values for whether span() and similar functions continue while
- * the current character is contained vs. not contained in the set.
- *
- * The functionality is straightforward for sets with only single code points,
- * without strings (which is the common case):
- * - USET_SPAN_CONTAINED and USET_SPAN_SIMPLE
- * work the same.
- * - span() and spanBack() partition any string the same way when
- * alternating between span(USET_SPAN_NOT_CONTAINED) and
- * span(either "contained" condition).
- * - Using a complemented (inverted) set and the opposite span conditions
- * yields the same results.
- *
- * When a set contains multi-code point strings, then these statements may not
- * be true, depending on the strings in the set (for example, whether they
- * overlap with each other) and the string that is processed.
- * For a set with strings:
- * - The complement of the set contains the opposite set of code points,
- * but the same set of strings.
- * Therefore, complementing both the set and the span conditions
- * may yield different results.
- * - When starting spans at different positions in a string
- * (span(s, ...) vs. span(s+1, ...)) the ends of the spans may be different
- * because a set string may start before the later position.
- * - span(USET_SPAN_SIMPLE) may be shorter than
- * span(USET_SPAN_CONTAINED) because it will not recursively try
- * all possible paths.
- * For example, with a set which contains the three strings "xy", "xya" and "ax",
- * span("xyax", USET_SPAN_CONTAINED) will return 4 but
- * span("xyax", USET_SPAN_SIMPLE) will return 3.
- * span(USET_SPAN_SIMPLE) will never be longer than
- * span(USET_SPAN_CONTAINED).
- * - With either "contained" condition, span() and spanBack() may partition
- * a string in different ways.
- * For example, with a set which contains the two strings "ab" and "ba",
- * and when processing the string "aba",
- * span() will yield contained/not-contained boundaries of { 0, 2, 3 }
- * while spanBack() will yield boundaries of { 0, 1, 3 }.
- *
- * Note: If it is important to get the same boundaries whether iterating forward
- * or backward through a string, then either only span() should be used and
- * the boundaries cached for backward operation, or an ICU BreakIterator
- * could be used.
- *
- * Note: Unpaired surrogates are treated like surrogate code points.
- * Similarly, set strings match only on code point boundaries,
- * never in the middle of a surrogate pair.
- * Illegal UTF-8 sequences are treated like U+FFFD.
- * When processing UTF-8 strings, malformed set strings
- * (strings with unpaired surrogates which cannot be converted to UTF-8)
- * are ignored.

+ * Argument values for whether span() and similar functions continue while
+ * the current character is contained vs. not contained in the set.
+ *
+ * The functionality is straightforward for sets with only single code points,
+ * without strings (which is the common case):
+ * - USET_SPAN_CONTAINED and USET_SPAN_SIMPLE
+ * work the same.
+ * - span() and spanBack() partition any string the same way when
+ * alternating between span(USET_SPAN_NOT_CONTAINED) and
+ * span(either "contained" condition).
+ * - Using a complemented (inverted) set and the opposite span conditions
+ * yields the same results.
+ *
+ * When a set contains multi-code point strings, then these statements may not
+ * be true, depending on the strings in the set (for example, whether they
+ * overlap with each other) and the string that is processed.
+ * For a set with strings:
+ * - The complement of the set contains the opposite set of code points,
+ * but the same set of strings.
+ * Therefore, complementing both the set and the span conditions
+ * may yield different results.
+ * - When starting spans at different positions in a string
+ * (span(s, ...) vs. span(s+1, ...)) the ends of the spans may be different
+ * because a set string may start before the later position.
+ * - span(USET_SPAN_SIMPLE) may be shorter than
+ * span(USET_SPAN_CONTAINED) because it will not recursively try
+ * all possible paths.
+ * For example, with a set which contains the three strings "xy", "xya" and "ax",
+ * span("xyax", USET_SPAN_CONTAINED) will return 4 but
+ * span("xyax", USET_SPAN_SIMPLE) will return 3.
+ * span(USET_SPAN_SIMPLE) will never be longer than
+ * span(USET_SPAN_CONTAINED).
+ * - With either "contained" condition, span() and spanBack() may partition
+ * a string in different ways.
+ * For example, with a set which contains the two strings "ab" and "ba",
+ * and when processing the string "aba",
+ * span() will yield contained/not-contained boundaries of { 0, 2, 3 }
+ * while spanBack() will yield boundaries of { 0, 1, 3 }.
+ *
+ * Note: If it is important to get the same boundaries whether iterating forward
+ * or backward through a string, then either only span() should be used and
+ * the boundaries cached for backward operation, or an ICU BreakIterator
+ * could be used.
+ *
+ * Note: Unpaired surrogates are treated like surrogate code points.
+ * Similarly, set strings match only on code point boundaries,
+ * never in the middle of a surrogate pair.
+ * Illegal UTF-8 sequences are treated like U+FFFD.
+ * When processing UTF-8 strings, malformed set strings
+ * (strings with unpaired surrogates which cannot be converted to UTF-8)
+ * are ignored.

- * \file

- *
- */
-
-/**
- * Shape Arabic text on a character basis.
- *
- * <p>This function performs basic operations for "shaping" Arabic text. It is most
- * useful for use with legacy data formats and legacy display technology
- * (simple terminals). All operations are performed on Unicode characters.</p>
- *
- * <p>Text-based shaping means that some character code points in the text are
- * replaced by others depending on the context. It transforms one kind of text
- * into another. In comparison, modern displays for Arabic text select
- * appropriate, context-dependent font glyphs for each text element, which means
- * that they transform text into a glyph vector.</p>
- *
- * <p>Text transformations are necessary when modern display technology is not
- * available or when text needs to be transformed to or from legacy formats that
- * use "shaped" characters. Since the Arabic script is cursive, connecting
- * adjacent letters to each other, computers select images for each letter based
- * on the surrounding letters. This usually results in four images per Arabic
- * letter: initial, middle, final, and isolated forms. In Unicode, on the other
- * hand, letters are normally stored abstract, and a display system is expected
- * to select the necessary glyphs. (This makes searching and other text
- * processing easier because the same letter has only one code.) It is possible
- * to mimic this with text transformations because there are characters in
- * Unicode that are rendered as letters with a specific shape
- * (or cursive connectivity). They were included for interoperability with
- * legacy systems and codepages, and for unsophisticated display systems.</p>
- *
- * <p>A second kind of text transformations is supported for Arabic digits:
- * For compatibility with legacy codepages that only include European digits,
- * it is possible to replace one set of digits by another, changing the
- * character code points. These operations can be performed for either
- * Arabic-Indic Digits (U+0660...U+0669) or Eastern (Extended) Arabic-Indic
- * digits (U+06f0...U+06f9).</p>
- *
- * <p>Some replacements may result in more or fewer characters (code points).
- * By default, this means that the destination buffer may receive text with a
- * length different from the source length. Some legacy systems rely on the
- * length of the text to be constant. They expect extra spaces to be added
- * or consumed either next to the affected character or at the end of the
- * text.</p>
- *
- * <p>For details about the available operations, see the description of the
- * <code>U_SHAPE_...</code> options.</p>
- *
- * @param source The input text.
- *
- * @param sourceLength The number of UChars in <code>source</code>.
- *
- * @param dest The destination buffer that will receive the results of the
- * requested operations. It may be <code>NULL</code> only if
- * <code>destSize</code> is 0. The source and destination must not
- * overlap.
- *
- * @param destSize The size (capacity) of the destination buffer in UChars.
- * If <code>destSize</code> is 0, then no output is produced,
- * but the necessary buffer size is returned ("preflighting").
- *
- * @param options This is a 32-bit set of flags that specify the operations
- * that are performed on the input text. If no error occurs,
- * then the result will always be written to the destination
- * buffer.
- *
- * @param pErrorCode must be a valid pointer to an error code value,
- * which must not indicate a failure before the function call.
- *
- * @return The number of UChars written to the destination buffer.
- * If an error occured, then no output was written, or it may be
- * incomplete. If <code>U_BUFFER_OVERFLOW_ERROR</code> is set, then
- * the return value indicates the necessary destination buffer size.

+ */
+
+/**
+ * Shape Arabic text on a character basis.
+ *
+ * <p>This function performs basic operations for "shaping" Arabic text. It is most
+ * useful for use with legacy data formats and legacy display technology
+ * (simple terminals). All operations are performed on Unicode characters.</p>
+ *
+ * <p>Text-based shaping means that some character code points in the text are
+ * replaced by others depending on the context. It transforms one kind of text
+ * into another. In comparison, modern displays for Arabic text select
+ * appropriate, context-dependent font glyphs for each text element, which means
+ * that they transform text into a glyph vector.</p>
+ *
+ * <p>Text transformations are necessary when modern display technology is not
+ * available or when text needs to be transformed to or from legacy formats that
+ * use "shaped" characters. Since the Arabic script is cursive, connecting
+ * adjacent letters to each other, computers select images for each letter based
+ * on the surrounding letters. This usually results in four images per Arabic
+ * letter: initial, middle, final, and isolated forms. In Unicode, on the other
+ * hand, letters are normally stored abstract, and a display system is expected
+ * to select the necessary glyphs. (This makes searching and other text
+ * processing easier because the same letter has only one code.) It is possible
+ * to mimic this with text transformations because there are characters in
+ * Unicode that are rendered as letters with a specific shape
+ * (or cursive connectivity). They were included for interoperability with
+ * legacy systems and codepages, and for unsophisticated display systems.</p>
+ *
+ * <p>A second kind of text transformations is supported for Arabic digits:
+ * For compatibility with legacy codepages that only include European digits,
+ * it is possible to replace one set of digits by another, changing the
+ * character code points. These operations can be performed for either
+ * Arabic-Indic Digits (U+0660...U+0669) or Eastern (Extended) Arabic-Indic
+ * digits (U+06f0...U+06f9).</p>
+ *
+ * <p>Some replacements may result in more or fewer characters (code points).
+ * By default, this means that the destination buffer may receive text with a
+ * length different from the source length. Some legacy systems rely on the
+ * length of the text to be constant. They expect extra spaces to be added
+ * or consumed either next to the affected character or at the end of the
+ * text.</p>
+ *
+ * <p>For details about the available operations, see the description of the
+ * <code>U_SHAPE_...</code> options.</p>
+ *
+ * @param source The input text.
+ *
+ * @param sourceLength The number of UChars in <code>source</code>.
+ *
+ * @param dest The destination buffer that will receive the results of the
+ * requested operations. It may be <code>NULL</code> only if
+ * <code>destSize</code> is 0. The source and destination must not
+ * overlap.
+ *
+ * @param destSize The size (capacity) of the destination buffer in UChars.
+ * If <code>destSize</code> is 0, then no output is produced,
+ * but the necessary buffer size is returned ("preflighting").
+ *
+ * @param options This is a 32-bit set of flags that specify the operations
+ * that are performed on the input text. If no error occurs,
+ * then the result will always be written to the destination
+ * buffer.
+ *
+ * @param pErrorCode must be a valid pointer to an error code value,
+ * which must not indicate a failure before the function call.
+ *
+ * @return The number of UChars written to the destination buffer.
+ * If an error occured, then no output was written, or it may be
+ * incomplete. If <code>U_BUFFER_OVERFLOW_ERROR</code> is set, then
+ * the return value indicates the necessary destination buffer size.

- TODO
- The following is a small list as to what is currently wrong/suggestions for
- ustdio.
-
- * Make sure that * in the scanf format specification works for all formats.
- * Each UFILE takes up at least 2KB.
- Look into adding setvbuf() for configurable buffers.
- * This library does buffering. The OS should do this for us already. Check on
- this, and remove it from this library, if this is the case. Double buffering
- wastes a lot of time and space.
- * Test stdin and stdout with the u_f* functions
- * Testing should be done for reading and writing multi-byte encodings,
- and make sure that a character that is contained across buffer boundries
- works even for incomplete characters.
- * Make sure that the last character is flushed when the file/string is closed.
- * snprintf should follow the C99 standard for the return value, which is
- return the number of characters (excluding the trailing '\0')
- which would have been written to the destination string regardless
- of available space. This is like pre-flighting.
- * Everything that uses %s should do what operator>> does for UnicodeString.
- It should convert one byte at a time, and once a character is
- converted then check to see if it's whitespace or in the scanset.
- If it's whitespace or in the scanset, put all the bytes back (do nothing
- for sprintf/sscanf).
- * If bad string data is encountered, make sure that the function fails
- without memory leaks and the unconvertable characters are valid
- substitution or are escaped characters.
- * u_fungetc() can't unget a character when it's at the beginning of the
- internal conversion buffer. For example, read the buffer size # of
- characters, and then ungetc to get the previous character that was
- at the end of the last buffer.
- * u_fflush() and u_fclose should return an int32_t like C99 functions.
- 0 is returned if the operation was successful and EOF otherwise.
- * u_fsettransliterator does not support U_READ side of transliteration.
- * The format specifier should limit the size of a format or honor it in
- order to prevent buffer overruns. (e.g. %256.256d).
- * u_fread and u_fwrite don't exist. They're needed for reading and writing
- data structures without any conversion.
- * u_file_read and u_file_write are used for writing strings. u_fgets and
- u_fputs or u_fread and u_fwrite should be used to do this.
- * The width parameter for all scanf formats, including scanset, needs
- better testing. This prevents buffer overflows.
- * Figure out what is suppose to happen when a codepage is changed midstream.
- Maybe a flush or a rewind are good enough.
- * Make sure that a UFile opened with "rw" can be used after using
- u_fflush with a u_frewind.
- * scanf(%i) should detect what type of number to use.
- * Add more testing of the alternate format, %#
- * Look at newline handling of fputs/puts
- * Think more about codeunit/codepoint error handling/support in %S,%s,%C,%c,%[]
- * Complete the file documentation with proper doxygen formatting.

- * \brief C API: Unicode stdio-like API
- *
- * <h2>Unicode stdio-like C API</h2>
- *
- * <p>This API provides an stdio-like API wrapper around ICU's other
- * formatting and parsing APIs. It is meant to ease the transition of adding
- * Unicode support to a preexisting applications using stdio. The following
- * is a small list of noticable differences between stdio and ICU I/O's
- * ustdio implementation.</p>
- *
- * <ul>
- * <li>Locale specific formatting and parsing is only done with file IO.</li>
- * <li>u_fstropen can be used to simulate file IO with strings.
- * This is similar to the iostream API, and it allows locale specific
- * formatting and parsing to be used.</li>
- * <li>This API provides uniform formatting and parsing behavior between
- * platforms (unlike the standard stdio implementations found on various
- * platforms).</li>
- * <li>This API is better suited for text data handling than binary data
- * handling when compared to the typical stdio implementation.</li>
- * <li>You can specify a Transliterator while using the file IO.</li>
- * <li>You can specify a file's codepage separately from the default
- * system codepage.</li>
- * </ul>
- *
- * <h2>Formatting and Parsing Specification</h2>
- *
- * General printf format:<br>
- * %[format modifier][width][.precision][type modifier][format]
- *
- * General scanf format:<br>
- * %[*][format modifier][width][type modifier][format]

+ TODO
+ The following is a small list as to what is currently wrong/suggestions for
+ ustdio.
+
+ * Make sure that * in the scanf format specification works for all formats.
+ * Each UFILE takes up at least 2KB.
+ Look into adding setvbuf() for configurable buffers.
+ * This library does buffering. The OS should do this for us already. Check on
+ this, and remove it from this library, if this is the case. Double buffering
+ wastes a lot of time and space.
+ * Test stdin and stdout with the u_f* functions
+ * Testing should be done for reading and writing multi-byte encodings,
+ and make sure that a character that is contained across buffer boundries
+ works even for incomplete characters.
+ * Make sure that the last character is flushed when the file/string is closed.
+ * snprintf should follow the C99 standard for the return value, which is
+ return the number of characters (excluding the trailing '\0')
+ which would have been written to the destination string regardless
+ of available space. This is like pre-flighting.
+ * Everything that uses %s should do what operator>> does for UnicodeString.
+ It should convert one byte at a time, and once a character is
+ converted then check to see if it's whitespace or in the scanset.
+ If it's whitespace or in the scanset, put all the bytes back (do nothing
+ for sprintf/sscanf).
+ * If bad string data is encountered, make sure that the function fails
+ without memory leaks and the unconvertable characters are valid
+ substitution or are escaped characters.
+ * u_fungetc() can't unget a character when it's at the beginning of the
+ internal conversion buffer. For example, read the buffer size # of
+ characters, and then ungetc to get the previous character that was
+ at the end of the last buffer.
+ * u_fflush() and u_fclose should return an int32_t like C99 functions.
+ 0 is returned if the operation was successful and EOF otherwise.
+ * u_fsettransliterator does not support U_READ side of transliteration.
+ * The format specifier should limit the size of a format or honor it in
+ order to prevent buffer overruns. (e.g. %256.256d).
+ * u_fread and u_fwrite don't exist. They're needed for reading and writing
+ data structures without any conversion.
+ * u_file_read and u_file_write are used for writing strings. u_fgets and
+ u_fputs or u_fread and u_fwrite should be used to do this.
+ * The width parameter for all scanf formats, including scanset, needs
+ better testing. This prevents buffer overflows.
+ * Figure out what is suppose to happen when a codepage is changed midstream.
+ Maybe a flush or a rewind are good enough.
+ * Make sure that a UFile opened with "rw" can be used after using
+ u_fflush with a u_frewind.
+ * scanf(%i) should detect what type of number to use.
+ * Add more testing of the alternate format, %#
+ * Look at newline handling of fputs/puts
+ * Think more about codeunit/codepoint error handling/support in %S,%s,%C,%c,%[]
+ * Complete the file documentation with proper doxygen formatting.
+ See http://oss.software.ibm.com/pipermail/icu/2003-July/005647.html

+ * \file
+ * \brief C API: Unicode stdio-like API
+ *
+ * <h2>Unicode stdio-like C API</h2>
+ *
+ * <p>This API provides an stdio-like API wrapper around ICU's other
+ * formatting and parsing APIs. It is meant to ease the transition of adding
+ * Unicode support to a preexisting applications using stdio. The following
+ * is a small list of noticable differences between stdio and ICU I/O's
+ * ustdio implementation.</p>
+ *
+ * <ul>
+ * <li>Locale specific formatting and parsing is only done with file IO.</li>
+ * <li>u_fstropen can be used to simulate file IO with strings.
+ * This is similar to the iostream API, and it allows locale specific
+ * formatting and parsing to be used.</li>
+ * <li>This API provides uniform formatting and parsing behavior between
+ * platforms (unlike the standard stdio implementations found on various
+ * platforms).</li>
+ * <li>This API is better suited for text data handling than binary data
+ * handling when compared to the typical stdio implementation.</li>
+ * <li>You can specify a Transliterator while using the file IO.</li>
+ * <li>You can specify a file's codepage separately from the default
+ * system codepage.</li>
+ * </ul>
+ *
+ * <h2>Formatting and Parsing Specification</h2>

- * \file
- * \brief C API: Unicode string handling functions
- *
- * These C API functions provide general Unicode string handling.
- *
- * Some functions are equivalent in name, signature, and behavior to the ANSI C <string.h>
- * functions. (For example, they do not check for bad arguments like NULL string pointers.)
- * In some cases, only the thread-safe variant of such a function is implemented here
- * (see u_strtok_r()).
- *
- * Other functions provide more Unicode-specific functionality like locale-specific
- * upper/lower-casing and string comparison in code point order.
- *
- * ICU uses 16-bit Unicode (UTF-16) in the form of arrays of UChar code units.
- * UTF-16 encodes each Unicode code point with either one or two UChar code units.
- * (This is the default form of Unicode, and a forward-compatible extension of the original,
- * fixed-width form that was known as UCS-2. UTF-16 superseded UCS-2 with Unicode 2.0
- * in 1996.)
- *
- * Some APIs accept a 32-bit UChar32 value for a single code point.
- *
- * ICU also handles 16-bit Unicode text with unpaired surrogates.
- * Such text is not well-formed UTF-16.
- * Code-point-related functions treat unpaired surrogates as surrogate code points,
- * i.e., as separate units.
- *
- * Although UTF-16 is a variable-width encoding form (like some legacy multi-byte encodings),
- * it is much more efficient even for random access because the code unit values
- * for single-unit characters vs. lead units vs. trail units are completely disjoint.
- * This means that it is easy to determine character (code point) boundaries from
- * random offsets in the string.
- *
- * Unicode (UTF-16) string processing is optimized for the single-unit case.
- * Although it is important to support supplementary characters
- * (which use pairs of lead/trail code units called "surrogates"),
- * their occurrence is rare. Almost all characters in modern use require only
- * a single UChar code unit (i.e., their code point values are <=0xffff).
- *
- * For more details see the User Guide Strings chapter (http://icu-project.org/userguide/strings.html).
- * For a discussion of the handling of unpaired surrogates see also
- * Jitterbug 2145 and its icu mailing list proposal on 2002-sep-18.

+/**
+ * \file
+ * \brief C API: Unicode string handling functions
+ *
+ * These C API functions provide general Unicode string handling.
+ *
+ * Some functions are equivalent in name, signature, and behavior to the ANSI C <string.h>
+ * functions. (For example, they do not check for bad arguments like NULL string pointers.)
+ * In some cases, only the thread-safe variant of such a function is implemented here
+ * (see u_strtok_r()).
+ *
+ * Other functions provide more Unicode-specific functionality like locale-specific
+ * upper/lower-casing and string comparison in code point order.
+ *
+ * ICU uses 16-bit Unicode (UTF-16) in the form of arrays of UChar code units.
+ * UTF-16 encodes each Unicode code point with either one or two UChar code units.
+ * (This is the default form of Unicode, and a forward-compatible extension of the original,
+ * fixed-width form that was known as UCS-2. UTF-16 superseded UCS-2 with Unicode 2.0
+ * in 1996.)
+ *
+ * Some APIs accept a 32-bit UChar32 value for a single code point.
+ *
+ * ICU also handles 16-bit Unicode text with unpaired surrogates.
+ * Such text is not well-formed UTF-16.
+ * Code-point-related functions treat unpaired surrogates as surrogate code points,
+ * i.e., as separate units.
+ *
+ * Although UTF-16 is a variable-width encoding form (like some legacy multi-byte encodings),
+ * it is much more efficient even for random access because the code unit values
+ * for single-unit characters vs. lead units vs. trail units are completely disjoint.
+ * This means that it is easy to determine character (code point) boundaries from
+ * random offsets in the string.
+ *
+ * Unicode (UTF-16) string processing is optimized for the single-unit case.
+ * Although it is important to support supplementary characters
+ * (which use pairs of lead/trail code units called "surrogates"),
+ * their occurrence is rare. Almost all characters in modern use require only
+ * a single UChar code unit (i.e., their code point values are <=0xffff).
+ *
+ * For more details see the User Guide Strings chapter (http://icu-project.org/userguide/strings.html).
+ * For a discussion of the handling of unpaired surrogates see also
+ * Jitterbug 2145 and its icu mailing list proposal on 2002-sep-18.

-/**
- * \file
- * \brief C API: Abstract Unicode Text API
- *
- * The Text Access API provides a means to allow text that is stored in alternative
- * formats to work with ICU services. ICU normally operates on text that is
- * stored in UTF-16 format, in (UChar *) arrays for the C APIs or as type
- * UnicodeString for C++ APIs.
- *
- * ICU Text Access allows other formats, such as UTF-8 or non-contiguous
- * UTF-16 strings, to be placed in a UText wrapper and then passed to ICU services.
- *
- * There are three general classes of usage for UText:
- *
- * Application Level Use. This is the simplest usage - applications would
- * use one of the utext_open() functions on their input text, and pass
- * the resulting UText to the desired ICU service.
- *
- * Second is usage in ICU Services, such as break iteration, that will need to
- * operate on input presented to them as a UText. These implementations
- * will need to use the iteration and related UText functions to gain
- * access to the actual text.
- *
- * The third class of UText users are "text providers." These are the
- * UText implementations for the various text storage formats. An application
- * or system with a unique text storage format can implement a set of
- * UText provider functions for that format, which will then allow
- * ICU services to operate on that format.
- *
- *
- * <em>Iterating over text</em>
- *
- * Here is sample code for a forward iteration over the contents of a UText
- *
- * \code
- * UChar32 c;
- * UText *ut = whatever();
- *
- * for (c=utext_next32From(ut, 0); c>=0; c=utext_next32(ut)) {
- * // do whatever with the codepoint c here.
- * }
- * \endcode
- *
- * And here is similar code to iterate in the reverse direction, from the end
- * of the text towards the beginning.
- *
- * \code
- * UChar32 c;
- * UText *ut = whatever();
- * int textLength = utext_nativeLength(ut);
- * for (c=utext_previous32From(ut, textLength); c>=0; c=utext_previous32(ut)) {
- * // do whatever with the codepoint c here.
- * }
- * \endcode
- *
- * <em>Characters and Indexing</em>
- *
- * Indexing into text by UText functions is nearly always in terms of the native
- * indexing of the underlying text storage. The storage format could be UTF-8
- * or UTF-32, for example. When coding to the UText access API, no assumptions
- * can be made regarding the size of characters, or how far an index
- * may move when iterating between characters.
- *
- * All indices supplied to UText functions are pinned to the length of the
- * text. An out-of-bounds index is not considered to be an error, but is
- * adjusted to be in the range 0 <= index <= length of input text.
- *
- *
- * When an index position is returned from a UText function, it will be
- * a native index to the underlying text. In the case of multi-unit characters,
- * it will always refer to the first position of the character,
- * never to the interior. This is essentially the same thing as saying that
- * a returned index will always point to a boundary between characters.
- *
- * When a native index is supplied to a UText function, all indices that
- * refer to any part of a multi-unit character representation are considered
- * to be equivalent. In the case of multi-unit characters, an incoming index
- * will be logically normalized to refer to the start of the character.
- *
- * It is possible to test whether a native index is on a code point boundary
- * by doing a utext_setNativeIndex() followed by a utext_getNativeIndex().
- * If the index is returned unchanged, it was on a code point boundary. If
- * an adjusted index is returned, the original index referred to the
- * interior of a character.
- *
- * <em>Conventions for calling UText functions</em>
- *
- * Most UText access functions have as their first parameter a (UText *) pointer,
- * which specifies the UText to be used. Unless otherwise noted, the
- * pointer must refer to a valid, open UText. Attempting to
- * use a closed UText or passing a NULL pointer is a programming error and
- * will produce undefined results or NULL pointer exceptions.
- *
- * The UText_Open family of functions can either open an existing (closed)
- * UText, or heap allocate a new UText. Here is sample code for creating
- * a stack-allocated UText.
- *
- * \code
- * char *s = whatever(); // A utf-8 string
- * U_ErrorCode status = U_ZERO_ERROR;
- * UText ut = UTEXT_INITIALIZER;
- * utext_openUTF8(ut, s, -1, &status);
- * if (U_FAILURE(status)) {
- * // error handling
- * } else {
- * // work with the UText
- * }
- * \endcode
- *
- * Any existing UText passed to an open function _must_ have been initialized,
- * either by the UTEXT_INITIALIZER, or by having been originally heap-allocated
- * by an open function. Passing NULL will cause the open function to
- * heap-allocate and fully initialize a new UText.
- *

- *
- * Shallow UText clones should be avoided if the UText functions that modify the

+/**
+ * \file
+ * \brief C API: Abstract Unicode Text API
+ *
+ * The Text Access API provides a means to allow text that is stored in alternative
+ * formats to work with ICU services. ICU normally operates on text that is
+ * stored in UTF-16 format, in (UChar *) arrays for the C APIs or as type
+ * UnicodeString for C++ APIs.
+ *
+ * ICU Text Access allows other formats, such as UTF-8 or non-contiguous
+ * UTF-16 strings, to be placed in a UText wrapper and then passed to ICU services.
+ *
+ * There are three general classes of usage for UText:
+ *
+ * Application Level Use. This is the simplest usage - applications would
+ * use one of the utext_open() functions on their input text, and pass
+ * the resulting UText to the desired ICU service.
+ *
+ * Second is usage in ICU Services, such as break iteration, that will need to
+ * operate on input presented to them as a UText. These implementations
+ * will need to use the iteration and related UText functions to gain
+ * access to the actual text.
+ *
+ * The third class of UText users are "text providers." These are the
+ * UText implementations for the various text storage formats. An application
+ * or system with a unique text storage format can implement a set of
+ * UText provider functions for that format, which will then allow
+ * ICU services to operate on that format.
+ *
+ *
+ * <em>Iterating over text</em>
+ *
+ * Here is sample code for a forward iteration over the contents of a UText
+ *
+ * \code
+ * UChar32 c;
+ * UText *ut = whatever();
+ *
+ * for (c=utext_next32From(ut, 0); c>=0; c=utext_next32(ut)) {
+ * // do whatever with the codepoint c here.
+ * }
+ * \endcode
+ *
+ * And here is similar code to iterate in the reverse direction, from the end
+ * of the text towards the beginning.
+ *
+ * \code
+ * UChar32 c;
+ * UText *ut = whatever();
+ * int textLength = utext_nativeLength(ut);
+ * for (c=utext_previous32From(ut, textLength); c>=0; c=utext_previous32(ut)) {
+ * // do whatever with the codepoint c here.
+ * }
+ * \endcode
+ *
+ * <em>Characters and Indexing</em>
+ *
+ * Indexing into text by UText functions is nearly always in terms of the native
+ * indexing of the underlying text storage. The storage format could be UTF-8
+ * or UTF-32, for example. When coding to the UText access API, no assumptions
+ * can be made regarding the size of characters, or how far an index
+ * may move when iterating between characters.
+ *
+ * All indices supplied to UText functions are pinned to the length of the
+ * text. An out-of-bounds index is not considered to be an error, but is
+ * adjusted to be in the range 0 <= index <= length of input text.
+ *
+ *
+ * When an index position is returned from a UText function, it will be
+ * a native index to the underlying text. In the case of multi-unit characters,
+ * it will always refer to the first position of the character,
+ * never to the interior. This is essentially the same thing as saying that
+ * a returned index will always point to a boundary between characters.
+ *
+ * When a native index is supplied to a UText function, all indices that
+ * refer to any part of a multi-unit character representation are considered
+ * to be equivalent. In the case of multi-unit characters, an incoming index
+ * will be logically normalized to refer to the start of the character.
+ *
+ * It is possible to test whether a native index is on a code point boundary
+ * by doing a utext_setNativeIndex() followed by a utext_getNativeIndex().
+ * If the index is returned unchanged, it was on a code point boundary. If
+ * an adjusted index is returned, the original index referred to the
+ * interior of a character.
+ *
+ * <em>Conventions for calling UText functions</em>
+ *
+ * Most UText access functions have as their first parameter a (UText *) pointer,
+ * which specifies the UText to be used. Unless otherwise noted, the
+ * pointer must refer to a valid, open UText. Attempting to
+ * use a closed UText or passing a NULL pointer is a programming error and
+ * will produce undefined results or NULL pointer exceptions.
+ *
+ * The UText_Open family of functions can either open an existing (closed)
+ * UText, or heap allocate a new UText. Here is sample code for creating
+ * a stack-allocated UText.
+ *
+ * \code
+ * char *s = whatever(); // A utf-8 string
+ * U_ErrorCode status = U_ZERO_ERROR;
+ * UText ut = UTEXT_INITIALIZER;
+ * utext_openUTF8(ut, s, -1, &status);
+ * if (U_FAILURE(status)) {
+ * // error handling
+ * } else {
+ * // work with the UText
+ * }
+ * \endcode
+ *
+ * Any existing UText passed to an open function _must_ have been initialized,
+ * either by the UTEXT_INITIALIZER, or by having been originally heap-allocated
+ * by an open function. Passing NULL will cause the open function to
+ * heap-allocate and fully initialize a new UText.

-/**
- * \file
- * \brief C API: Code point macros
- *
- * This file defines macros for checking whether a code point is
- * a surrogate or a non-character etc.
- *
- * The UChar and UChar32 data types for Unicode code units and code points
- * are defined in umachines.h because they can be machine-dependent.
- *
- * utf.h is included by utypes.h and itself includes utf8.h and utf16.h after some
- * common definitions. Those files define macros for efficiently getting code points
- * in and out of UTF-8/16 strings.
- * utf16.h macros have "U16_" prefixes.
- * utf8.h defines similar macros with "U8_" prefixes for UTF-8 string handling.
- *
- * ICU processes 16-bit Unicode strings.
- * Most of the time, such strings are well-formed UTF-16.
- * Single, unpaired surrogates must be handled as well, and are treated in ICU
- * like regular code points where possible.
- * (Pairs of surrogate code points are indistinguishable from supplementary
- * code points encoded as pairs of supplementary code units.)
- *
- * In fact, almost all Unicode code points in normal text (>99%)
- * are on the BMP (<=U+ffff) and even <=U+d7ff.
- * ICU functions handle supplementary code points (U+10000..U+10ffff)
- * but are optimized for the much more frequently occurring BMP code points.
- *
- * utf.h defines UChar to be an unsigned 16-bit integer. If this matches wchar_t, then
- * UChar is defined to be exactly wchar_t, otherwise uint16_t.
- *
- * UChar32 is defined to be a signed 32-bit integer (int32_t), large enough for a 21-bit
- * Unicode code point (Unicode scalar value, 0..0x10ffff).
- * Before ICU 2.4, the definition of UChar32 was similarly platform-dependent as
- * the definition of UChar. For details see the documentation for UChar32 itself.
- *
- * utf.h also defines a small number of C macros for single Unicode code points.
- * These are simple checks for surrogates and non-characters.
- * For actual Unicode character properties see uchar.h.
- *
- * By default, string operations must be done with error checking in case
- * a string is not well-formed UTF-16.
- * The macros will detect if a surrogate code unit is unpaired
- * (lead unit without trail unit or vice versa) and just return the unit itself
- * as the code point.
- * (It is an accidental property of Unicode and UTF-16 that all
- * malformed sequences can be expressed unambiguously with a distinct subrange
- * of Unicode code points.)
- *
- * The regular "safe" macros require that the initial, passed-in string index
- * is within bounds. They only check the index when they read more than one
- * code unit. This is usually done with code similar to the following loop:
- * <pre>while(i<length) {
- * U16_NEXT(s, i, length, c);
- * // use c
- * }</pre>
- *
- * When it is safe to assume that text is well-formed UTF-16
- * (does not contain single, unpaired surrogates), then one can use
- * U16_..._UNSAFE macros.
- * These do not check for proper code unit sequences or truncated text and may
- * yield wrong results or even cause a crash if they are used with "malformed"
- * text.
- * In practice, U16_..._UNSAFE macros will produce slightly less code but
- * should not be faster because the processing is only different when a
- * surrogate code unit is detected, which will be rare.
- *
- * Similarly for UTF-8, there are "safe" macros without a suffix,
- * and U8_..._UNSAFE versions.
- * The performance differences are much larger here because UTF-8 provides so
- * many opportunities for malformed sequences.
- * The unsafe UTF-8 macros are entirely implemented inside the macro definitions
- * and are fast, while the safe UTF-8 macros call functions for all but the
- * trivial (ASCII) cases.
- * (ICU 3.6 optimizes U8_NEXT() and U8_APPEND() to handle most other common
- * characters inline as well.)
- *
- * Unlike with UTF-16, malformed sequences cannot be expressed with distinct
- * code point values (0..U+10ffff). They are indicated with negative values instead.
- *
- * For more information see the ICU User Guide Strings chapter
- * (http://icu-project.org/userguide/strings.html).
- *
- * <em>Usage:</em>
- * ICU coding guidelines for if() statements should be followed when using these macros.
- * Compound statements (curly braces {}) must be used for if-else-while...
- * bodies and all macro statements should be terminated with semicolon.

+ * For actual Unicode character properties see uchar.h.
+ *
+ * By default, string operations must be done with error checking in case
+ * a string is not well-formed UTF-16.
+ * The macros will detect if a surrogate code unit is unpaired
+ * (lead unit without trail unit or vice versa) and just return the unit itself
+ * as the code point.
+ * (It is an accidental property of Unicode and UTF-16 that all
+ * malformed sequences can be expressed unambiguously with a distinct subrange
+ * of Unicode code points.)
+ *
+ * The regular "safe" macros require that the initial, passed-in string index
+ * is within bounds. They only check the index when they read more than one
+ * code unit. This is usually done with code similar to the following loop:
+ * <pre>while(i<length) {
+ * U16_NEXT(s, i, length, c);
+ * // use c
+ * }</pre>
+ *
+ * When it is safe to assume that text is well-formed UTF-16
+ * (does not contain single, unpaired surrogates), then one can use
+ * U16_..._UNSAFE macros.
+ * These do not check for proper code unit sequences or truncated text and may
+ * yield wrong results or even cause a crash if they are used with "malformed"
+ * text.
+ * In practice, U16_..._UNSAFE macros will produce slightly less code but
+ * should not be faster because the processing is only different when a
+ * surrogate code unit is detected, which will be rare.
+ *
+ * Similarly for UTF-8, there are "safe" macros without a suffix,
+ * and U8_..._UNSAFE versions.
+ * The performance differences are much larger here because UTF-8 provides so
+ * many opportunities for malformed sequences.
+ * The unsafe UTF-8 macros are entirely implemented inside the macro definitions
+ * and are fast, while the safe UTF-8 macros call functions for all but the
+ * trivial (ASCII) cases.
+ * (ICU 3.6 optimizes U8_NEXT() and U8_APPEND() to handle most other common
+ * characters inline as well.)
+ *
+ * Unlike with UTF-16, malformed sequences cannot be expressed with distinct
+ * code point values (0..U+10ffff). They are indicated with negative values instead.
+ *
+ * For more information see the ICU User Guide Strings chapter
+ * (http://icu-project.org/userguide/strings.html).
+ *
+ * <em>Usage:</em>
+ * ICU coding guidelines for if() statements should be followed when using these macros.
+ * Compound statements (curly braces {}) must be used for if-else-while...
+ * bodies and all macro statements should be terminated with semicolon.

- * \file
- * \brief C API: Deprecated macros for Unicode string handling
- */
-
-/**
- *
- * The macros in utf_old.h are all deprecated and their use discouraged.
- * Some of the design principles behind the set of UTF macros
- * have changed or proved impractical.
- * Almost all of the old "UTF macros" are at least renamed.
- * If you are looking for a new equivalent to an old macro, please see the
- * comment at the old one.
- *
- * utf_old.h is included by utf.h after unicode/umachine.h
- * and some common definitions, to not break old code.
- *
- * Brief summary of reasons for deprecation:
- * - Switch on UTF_SIZE (selection of UTF-8/16/32 default string processing)
- * was impractical.
- * - Switch on UTF_SAFE etc. (selection of unsafe/safe/strict default string processing)
- * was of little use and impractical.
- * - Whole classes of macros became obsolete outside of the UTF_SIZE/UTF_SAFE
- * selection framework: UTF32_ macros (all trivial)
- * and UTF_ default and intermediate macros (all aliases).
- * - The selection framework also caused many macro aliases.
- * - Change in Unicode standard: "irregular" sequences (3.0) became illegal (3.2).
- * - Change of language in Unicode standard:
- * Growing distinction between internal x-bit Unicode strings and external UTF-x
- * forms, with the former more lenient.
- * Suggests renaming of UTF16_ macros to U16_.
- * - The prefix "UTF_" without a width number confused some users.
- * - "Safe" append macros needed the addition of an error indicator output.
- * - "Safe" UTF-8 macros used legitimate (if rarely used) code point values
- * to indicate error conditions.
- * - The use of the "_CHAR" infix for code point operations confused some users.
- *
- * More details:
- *
- * Until ICU 2.2, utf.h theoretically allowed to choose among UTF-8/16/32
- * for string processing, and among unsafe/safe/strict default macros for that.
- *
- * It proved nearly impossible to write non-trivial, high-performance code
- * that is UTF-generic.
- * Unsafe default macros would be dangerous for default string processing,
- * and the main reason for the "strict" versions disappeared:
- * Between Unicode 3.0 and 3.2 all "irregular" UTF-8 sequences became illegal.
- * The only other conditions that "strict" checked for were non-characters,
- * which are valid during processing. Only during text input/output should they
- * be checked, and at that time other well-formedness checks may be
- * necessary or useful as well.
- * This can still be done by using U16_NEXT and U_IS_UNICODE_NONCHAR
- * or U_IS_UNICODE_CHAR.
- *
- * The old UTF8_..._SAFE macros also used some normal Unicode code points
- * to indicate malformed sequences.
- * The new UTF8_ macros without suffix use negative values instead.
- *
- * The entire contents of utf32.h was moved here without replacement
- * because all those macros were trivial and
- * were meaningful only in the framework of choosing the UTF size.
- *
- * See Jitterbug 2150 and its discussion on the ICU mailing list
- * in September 2002.
- *
- * <hr>
- *
- * <em>Obsolete part</em> of pre-ICU 2.4 utf.h file documentation:
- *
- * <p>The original concept for these files was for ICU to allow
- * in principle to set which UTF (UTF-8/16/32) is used internally
- * by defining UTF_SIZE to either 8, 16, or 32. utf.h would then define the UChar type
- * accordingly. UTF-16 was the default.</p>
- *
- * <p>This concept has been abandoned.
- * A lot of the ICU source code assumes UChar strings are in UTF-16.
- * This is especially true for low-level code like
- * conversion, normalization, and collation.
- * The utf.h header enforces the default of UTF-16.
- * The UTF-8 and UTF-32 macros remain for now for completeness and backward compatibility.</p>
- *
- * <p>Accordingly, utf.h defines UChar to be an unsigned 16-bit integer. If this matches wchar_t, then
- * UChar is defined to be exactly wchar_t, otherwise uint16_t.</p>
- *
- * <p>UChar32 is defined to be a signed 32-bit integer (int32_t), large enough for a 21-bit
- * Unicode code point (Unicode scalar value, 0..0x10ffff).
- * Before ICU 2.4, the definition of UChar32 was similarly platform-dependent as
- * the definition of UChar. For details see the documentation for UChar32 itself.</p>
- *
- * <p>utf.h also defines a number of C macros for handling single Unicode code points and
- * for using UTF Unicode strings. It includes utf8.h, utf16.h, and utf32.h for the actual
- * implementations of those macros and then aliases one set of them (for UTF-16) for general use.
- * The UTF-specific macros have the UTF size in the macro name prefixes (UTF16_...), while
- * the general alias macros always begin with UTF_...</p>
- *
- * <p>Many string operations can be done with or without error checking.
- * Where such a distinction is useful, there are two versions of the macros, "unsafe" and "safe"
- * ones with ..._UNSAFE and ..._SAFE suffixes. The unsafe macros are fast but may cause
- * program failures if the strings are not well-formed. The safe macros have an additional, boolean
- * parameter "strict". If strict is FALSE, then only illegal sequences are detected.
- * Otherwise, irregular sequences and non-characters are detected as well (like single surrogates).
- * Safe macros return special error code points for illegal/irregular sequences:
- * Typically, U+ffff, or values that would result in a code unit sequence of the same length
- * as the erroneous input sequence.<br>
- * Note that _UNSAFE macros have fewer parameters: They do not have the strictness parameter, and
- * they do not have start/length parameters for boundary checking.</p>
- *
- * <p>Here, the macros are aliased in two steps:
- * In the first step, the UTF-specific macros with UTF16_ prefix and _UNSAFE and _SAFE suffixes are
- * aliased according to the UTF_SIZE to macros with UTF_ prefix and the same suffixes and signatures.
- * Then, in a second step, the default, general alias macros are set to use either the unsafe or
- * the safe/not strict (default) or the safe/strict macro;
- * these general macros do not have a strictness parameter.</p>
- *
- * <p>It is possible to change the default choice for the general alias macros to be unsafe, safe/not strict or safe/strict.
- * The default is safe/not strict. It is not recommended to select the unsafe macros as the basis for
- * Unicode string handling in ICU! To select this, define UTF_SAFE, UTF_STRICT, or UTF_UNSAFE.</p>
- *
- * <p>For general use, one should use the default, general macros with UTF_ prefix and no _SAFE/_UNSAFE suffix.
- * Only in some cases it may be necessary to control the choice of macro directly and use a less generic alias.
- * For example, if it can be assumed that a string is well-formed and the index will stay within the bounds,
- * then the _UNSAFE version may be used.
- * If a UTF-8 string is to be processed, then the macros with UTF8_ prefixes need to be used.</p>
- *
- * <hr>
- *
- * @deprecated ICU 2.4. Use the macros in utf.h, utf16.h, utf8.h instead.

+ * \file
+ * \brief C API: Deprecated macros for Unicode string handling
+ */
+
+/**
+ *
+ * The macros in utf_old.h are all deprecated and their use discouraged.
+ * Some of the design principles behind the set of UTF macros
+ * have changed or proved impractical.
+ * Almost all of the old "UTF macros" are at least renamed.
+ * If you are looking for a new equivalent to an old macro, please see the
+ * comment at the old one.
+ *
+ * utf_old.h is included by utf.h after unicode/umachine.h
+ * and some common definitions, to not break old code.
+ *
+ * Brief summary of reasons for deprecation:
+ * - Switch on UTF_SIZE (selection of UTF-8/16/32 default string processing)
+ * was impractical.
+ * - Switch on UTF_SAFE etc. (selection of unsafe/safe/strict default string processing)
+ * was of little use and impractical.
+ * - Whole classes of macros became obsolete outside of the UTF_SIZE/UTF_SAFE
+ * selection framework: UTF32_ macros (all trivial)
+ * and UTF_ default and intermediate macros (all aliases).
+ * - The selection framework also caused many macro aliases.
+ * - Change in Unicode standard: "irregular" sequences (3.0) became illegal (3.2).
+ * - Change of language in Unicode standard:
+ * Growing distinction between internal x-bit Unicode strings and external UTF-x
+ * forms, with the former more lenient.
+ * Suggests renaming of UTF16_ macros to U16_.
+ * - The prefix "UTF_" without a width number confused some users.
+ * - "Safe" append macros needed the addition of an error indicator output.
+ * - "Safe" UTF-8 macros used legitimate (if rarely used) code point values
+ * to indicate error conditions.
+ * - The use of the "_CHAR" infix for code point operations confused some users.
+ *
+ * More details:
+ *
+ * Until ICU 2.2, utf.h theoretically allowed to choose among UTF-8/16/32
+ * for string processing, and among unsafe/safe/strict default macros for that.
+ *
+ * It proved nearly impossible to write non-trivial, high-performance code
+ * that is UTF-generic.
+ * Unsafe default macros would be dangerous for default string processing,
+ * and the main reason for the "strict" versions disappeared:
+ * Between Unicode 3.0 and 3.2 all "irregular" UTF-8 sequences became illegal.
+ * The only other conditions that "strict" checked for were non-characters,
+ * which are valid during processing. Only during text input/output should they
+ * be checked, and at that time other well-formedness checks may be
+ * necessary or useful as well.
+ * This can still be done by using U16_NEXT and U_IS_UNICODE_NONCHAR
+ * or U_IS_UNICODE_CHAR.
+ *
+ * The old UTF8_..._SAFE macros also used some normal Unicode code points
+ * to indicate malformed sequences.
+ * The new UTF8_ macros without suffix use negative values instead.
+ *
+ * The entire contents of utf32.h was moved here without replacement
+ * because all those macros were trivial and
+ * were meaningful only in the framework of choosing the UTF size.
+ *
+ * See Jitterbug 2150 and its discussion on the ICU mailing list
+ * in September 2002.
+ *
+ * <hr>
+ *
+ * <em>Obsolete part</em> of pre-ICU 2.4 utf.h file documentation:
+ *
+ * <p>The original concept for these files was for ICU to allow
+ * in principle to set which UTF (UTF-8/16/32) is used internally
+ * by defining UTF_SIZE to either 8, 16, or 32. utf.h would then define the UChar type
+ * accordingly. UTF-16 was the default.</p>
+ *
+ * <p>This concept has been abandoned.
+ * A lot of the ICU source code assumes UChar strings are in UTF-16.
+ * This is especially true for low-level code like
+ * conversion, normalization, and collation.
+ * The utf.h header enforces the default of UTF-16.
+ * The UTF-8 and UTF-32 macros remain for now for completeness and backward compatibility.</p>
+ *
+ * <p>Accordingly, utf.h defines UChar to be an unsigned 16-bit integer. If this matches wchar_t, then
+ * UChar is defined to be exactly wchar_t, otherwise uint16_t.</p>
+ *
+ * <p>UChar32 is defined to be a signed 32-bit integer (int32_t), large enough for a 21-bit
+ * Unicode code point (Unicode scalar value, 0..0x10ffff).
+ * Before ICU 2.4, the definition of UChar32 was similarly platform-dependent as
+ * the definition of UChar. For details see the documentation for UChar32 itself.</p>
+ *
+ * <p>utf.h also defines a number of C macros for handling single Unicode code points and
+ * for using UTF Unicode strings. It includes utf8.h, utf16.h, and utf32.h for the actual
+ * implementations of those macros and then aliases one set of them (for UTF-16) for general use.
+ * The UTF-specific macros have the UTF size in the macro name prefixes (UTF16_...), while
+ * the general alias macros always begin with UTF_...</p>
+ *
+ * <p>Many string operations can be done with or without error checking.
+ * Where such a distinction is useful, there are two versions of the macros, "unsafe" and "safe"
+ * ones with ..._UNSAFE and ..._SAFE suffixes. The unsafe macros are fast but may cause
+ * program failures if the strings are not well-formed. The safe macros have an additional, boolean
+ * parameter "strict". If strict is FALSE, then only illegal sequences are detected.
+ * Otherwise, irregular sequences and non-characters are detected as well (like single surrogates).
+ * Safe macros return special error code points for illegal/irregular sequences:
+ * Typically, U+ffff, or values that would result in a code unit sequence of the same length
+ * as the erroneous input sequence.<br>
+ * Note that _UNSAFE macros have fewer parameters: They do not have the strictness parameter, and
+ * they do not have start/length parameters for boundary checking.</p>
+ *
+ * <p>Here, the macros are aliased in two steps:
+ * In the first step, the UTF-specific macros with UTF16_ prefix and _UNSAFE and _SAFE suffixes are
+ * aliased according to the UTF_SIZE to macros with UTF_ prefix and the same suffixes and signatures.
+ * Then, in a second step, the default, general alias macros are set to use either the unsafe or
+ * the safe/not strict (default) or the safe/strict macro;
+ * these general macros do not have a strictness parameter.</p>
+ *
+ * <p>It is possible to change the default choice for the general alias macros to be unsafe, safe/not strict or safe/strict.
+ * The default is safe/not strict. It is not recommended to select the unsafe macros as the basis for
+ * Unicode string handling in ICU! To select this, define UTF_SAFE, UTF_STRICT, or UTF_UNSAFE.</p>
+ *
+ * <p>For general use, one should use the default, general macros with UTF_ prefix and no _SAFE/_UNSAFE suffix.
+ * Only in some cases it may be necessary to control the choice of macro directly and use a less generic alias.
+ * For example, if it can be assumed that a string is well-formed and the index will stay within the bounds,
+ * then the _UNSAFE version may be used.
+ * If a UTF-8 string is to be processed, then the macros with UTF8_ prefixes need to be used.</p>
+ *
+ * <hr>
+ *
+ * @deprecated ICU 2.4. Use the macros in utf.h, utf16.h, utf8.h instead.

-/**
- * \file
- * \brief C API: Universal Time Scale
- *
- * There are quite a few different conventions for binary datetime, depending on different
- * platforms and protocols. Some of these have severe drawbacks. For example, people using
- * Unix time (seconds since Jan 1, 1970) think that they are safe until near the year 2038.
- * But cases can and do arise where arithmetic manipulations causes serious problems. Consider
- * the computation of the average of two datetimes, for example: if one calculates them with
- * <code>averageTime = (time1 + time2)/2</code>, there will be overflow even with dates
- * around the present. Moreover, even if these problems don't occur, there is the issue of
- * conversion back and forth between different systems.
- *
- * <p>
- * Binary datetimes differ in a number of ways: the datatype, the unit,
- * and the epoch (origin). We'll refer to these as time scales. For example:

- *
- *<p>
- * Because of these issues, we ended up concluding that the .NET framework's

- * This time scale is very fine grained, does not lose precision, and covers a range that
- * will meet almost all requirements. It will not handle the range that Java times do,
- * but frankly, being able to handle dates before 29,000 BC or after 29,000 AD is of very limited interest.

+/**
+ * \file
+ * \brief C API: Universal Time Scale
+ *
+ * There are quite a few different conventions for binary datetime, depending on different
+ * platforms and protocols. Some of these have severe drawbacks. For example, people using
+ * Unix time (seconds since Jan 1, 1970) think that they are safe until near the year 2038.
+ * But cases can and do arise where arithmetic manipulations causes serious problems. Consider
+ * the computation of the average of two datetimes, for example: if one calculates them with
+ * <code>averageTime = (time1 + time2)/2</code>, there will be overflow even with dates
+ * around the present. Moreover, even if these problems don't occur, there is the issue of
+ * conversion back and forth between different systems.
+ *
+ * <p>
+ * Binary datetimes differ in a number of ways: the datatype, the unit,
+ * and the epoch (origin). We'll refer to these as time scales. For example:

- * \brief C API: Transliterator
- *
- * <h2> Transliteration </h2>
- * The data structures and functions described in this header provide
- * transliteration services. Transliteration services are implemented
- * as C++ classes. The comments and documentation in this header
- * assume the reader is familiar with the C++ headers translit.h and
- * associated documentation.
- *
- * A significant but incomplete subset of the C++ transliteration
- * services are available to C code through this header. In order to
- * access more complex transliteration services, refer to the C++
- * headers and documentation.
- *
- * There are two sets of functions for working with transliterator IDs:
- *
- * An old, deprecated set uses char * IDs, which works for true and pure
- * identifiers that these APIs were designed for,
- * for example "Cyrillic-Latin".
- * It does not work when the ID contains filters ("[:Script=Cyrl:]")
- * or even a complete set of rules because then the ID string contains more
- * than just "invariant" characters (see utypes.h).
- *
- * A new set of functions replaces the old ones and uses UChar * IDs,
- * paralleling the UnicodeString IDs in the C++ API. (New in ICU 2.8.)

+ * \brief C API: Transliterator
+ *
+ * <h2> Transliteration </h2>
+ * The data structures and functions described in this header provide
+ * transliteration services. Transliteration services are implemented
+ * as C++ classes. The comments and documentation in this header
+ * assume the reader is familiar with the C++ headers translit.h and
+ * associated documentation.
+ *
+ * A significant but incomplete subset of the C++ transliteration
+ * services are available to C code through this header. In order to
+ * access more complex transliteration services, refer to the C++
+ * headers and documentation.
+ *
+ * There are two sets of functions for working with transliterator IDs:
+ *
+ * An old, deprecated set uses char * IDs, which works for true and pure
+ * identifiers that these APIs were designed for,
+ * for example "Cyrillic-Latin".
+ * It does not work when the ID contains filters ("[:Script=Cyrl:]")
+ * or even a complete set of rules because then the ID string contains more
+ * than just "invariant" characters (see utypes.h).
+ *
+ * A new set of functions replaces the old ones and uses UChar * IDs,
+ * paralleling the UnicodeString IDs in the C++ API. (New in ICU 2.8.)

- * It is enough to determine the code point values of "invariant characters",
- * which are the ones shared by all encodings that are in use
- * on a given platform.</p>
- *
- * <p>Those "invariant characters" should be all the uppercase and lowercase
- * latin letters, the digits, the space, and "basic punctuation".
- * Also, '\\n', '\\r', '\\t' should be available.</p>
- *
- * <p>The list of "invariant characters" is:<br>
- * \code
- * A-Z a-z 0-9 SPACE " % & ' ( ) * + , - . / : ; < = > ? _
- * \endcode
- * <br>
- * (52 letters + 10 numbers + 20 punc/sym/space = 82 total)</p>
- *
- * <p>This matches the IBM Syntactic Character Set (CS 640).</p>
- *
- * <p>In other words, all the graphic characters in 7-bit ASCII should
- * be safely accessible except the following:</p>
- *
- * \code
- * '\' <backslash>
- * '[' <left bracket>
