Class RandomAccessIterator<E>

java.lang.Object

ikr.simlib.support.RandomAccessIterator<E>

All Implemented Interfaces:

java.util.Iterator<E>

public class RandomAccessIterator<E>
extends java.lang.Object
implements java.util.Iterator<E>

A iterator for lists which should be able to extend during iteration. It won't work if new elements are inserted before the current element or if elements are removed.

This iterator will only work efficiently on lists that implement the RandomAccess interface.

(IMHO this is the best solution for a broken requirement)
