AS3 Iterator Factory API for Flex 2

Wednesday, December 13th, 2006

I have been posting updates of my utils package lately but haven’t had the time to walk through how to use the API’s in detail other than the provided ASDoc.

One of the really useful API’s in the utils package is the Iterator implementation. The Iterator API provides a standard implementation of the Iterator pattern and is useful for traversing an object, array or collection of objects. The Iterator API provides an Array Iterator, ArrayCollection Iterator and an Object Iterator. You can use them individually as needed but one of the coolest features is the Iterator Factory. The Iterator Factory handles iterator instantiation and allows a single iterator instance, typed as an IIterator interface, to use any of the iterators, via the Iterator Factory.

You can click here to view an example of how to use the Iterator Factory.
