    Overriding a rest parameter

      I have a method in a parent class that I need to override in a child, but the parent's version of the method uses a rest (...) parameter as its only argument.

      Since the argument arrives in the overridden class as an array, how do I then pass that data on to the original method (i.e. super.function())? Is there any way to indicate that an array should be treated like a rest parameter?

      I've since solved my application specific issue using a different approach, but I wasn't able to find anything that addressed the problem above in the Docs.

          Alex Harui over on FlexCoders graciously answered this one for me, so I'll post the answer here in case anyone else ever needs the reference.

          To pass a rest parameter, do the following:

          override public function foo(... rest):void
          super.foo.apply(this, rest);

          The apply() method is a member of the Function class, and is an alternate means of calling a method. The first parameter is a reference to your object, and the second is an array containing an arbitrary number of arguments.
