public abstract class AbstractIterator<E> extends Object implements Iterator<E>
Abstract iterator that allows overriding just the getNext() method to implement it. This iterator works on the premise that a null value returned from getNext() means that this iterator is complete. Note this iterator does not implement Iterator.remove() and is up to implementors to do so.
