Overview

Sometimes you don't want to have to throw out your iterator each time you have exhausted it. This class adds the "reset" method to allow reuse of an iterator. This is a very simple addition to the Array::Iterator class of a single method.

Methods

This is a subclass of Array::Iterator, only those methods that have been added are documented here, refer to the Array::Iterator documentation for more information.

reset

This resets the internal counter of the iterator back to the start of the array.
