org.apache.commons.collections.iterators.ObjectArrayIterator
An {@link Iterator} over an array of objects.
This iterator does not support {@link #remove}, as the object array cannot be structurally modified.
The iterator implements a {@link #reset} method, allowing the reset of the iteratorback to the start if required. @since Commons Collections 3.0 @version $Revision: 1.12 $ $Date: 2004/02/18 00:59:50 $ @author James Strachan @author Mauricio S.
