All Implemented Interfaces:

BidirectionalIterator<Integer>, IntBidirectionalIterator, IntIterator, IntListIterator, ObjectBidirectionalIterator<Integer>, ObjectIterator<Integer>, Serializable, Cloneable, Iterator<Integer>, ListIterator<Integer>

Enclosing class:

IntIterators

public static class IntIterators.EmptyIterator
extends AbstractIntListIterator
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.

IntIterators.EmptyIterator()

Method Summary

int	back(int n) This method just iterates the type-specific version of AbstractIntBidirectionalIterator.previous() for at most n times, stopping if BidirectionalIterator.hasPrevious() becomes false.
Object	clone()
boolean	hasNext()
boolean	hasPrevious() Returns whether there is a previous element.
int	nextIndex()
int	nextInt() Delegates to the corresponding generic method.
int	previousIndex()
int	previousInt() Delegates to the corresponding generic method.
int	skip(int n) This method just iterates the type-specific version of AbstractIntIterator.next() for at most n times, stopping if Iterator.hasNext() becomes false.
