All Implemented Interfaces:

BidirectionalIterator<K>, ObjectBidirectionalIterator<K>, ObjectIterator<K>, ObjectListIterator<K>, Serializable, Cloneable, Iterator<K>, ListIterator<K>

Enclosing class:

ObjectIterators

public static class ObjectIterators.EmptyIterator<K>
extends AbstractObjectListIterator<K>
implements Serializable, Cloneable

A class returning no elements and a type-specific iterator interface.

This class may be useful to implement your own in case you subclass a type-specific iterator.
