[MacRuby-devel] Overriding +autosavesInPlace

[Keith Gautreaux]

I'm not a Macruby expert and I don't know anything about Cocoa,
particularly as it relates to new Lion features such as autosave, but
the example code you gave is defining an instance method, not a class
method.

To override a class method you would need to do something like:

class MyDocument < NSPersistentDocument

...

  def self.autosavesInPlace
    return YES
  end
end

There are other ways of defining class methods but this is the easiest
when you just have one method.
