Examples of org.apache.commons.collections.iterators.ArrayIterator

org.apache.commons.collections.iterators.ArrayIterator
Implements an {@link java.util.Iterator Iterator} over any array.
The array can be either an array of object or of primitives. If you know that you have an object array, the {@link org.apache.commons.collections.iterators.ObjectArrayIterator ObjectArrayIterator}class is a better choice, as it will perform better.
The iterator implements a {@link #reset} method, allowing the reset of the iterator back to the start if required. @since Commons Collections 1.0 @version $Revision: 1.11 $ $Date: 2004/02/18 00:59:50 $ @author James Strachan @author Mauricio S.
