## org.apache.velocity.util
Class ArrayIterator

    java.lang.Object
      |
      +--org.apache.velocity.util.ArrayIterator

All Implemented Interfaces:
  java.util.Iterator

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

An Iterator wrapper for an Object[]. This will allow us to deal with all array like structures in a consistent manner.

WARNING : this class's operations are NOT synchronized. It is meant to be used in a single thread, newly created for each use in the #foreach() directive. If this is used or shared, synchronize in the next() method.
