Question

Lets say I have an ActionScript class: MyClass and that class has data in it. Now, lets say I want to iterate over that data using “for each”:

var myData:MyClass = new MyClass();
myData.Populate(fromSource);

for each(var item in myData) {
  DoSomethingWith(item);
}

Of course, this does nothing, because MyClass is a custom class, and I haven’t done anything special to it yet.

What do I need to do to MyClass to make it play nicely with “for each”? Can I hand it an iterator or an enumerator or something?

Answer 1

I believe you need to extend Proxy class and implement nextValue(index:int). It is used by for each.
