Class ArrayIterator

java.lang.Object
  net.sf.composite.util.ArrayIterator

All Implemented Interfaces:

java.util.Iterator

public class ArrayIterator
extends java.lang.Object
implements java.util.Iterator

An iterator over the contents of an array. This implementation only allows an array to be iterated over once, but a reset method could easily be added to allow for the array to be iterated over multiple times or for another array to use the same ArrayIterator instance as an iterator for it.
