    java.util.Iterator<java.lang.Object>
    public class ArrayIterator

implements java.util.Iterator<java.lang.Object>

    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.
