All Implemented Interfaces:

BidirectionalIterator<Long>, LongBidirectionalIterator, LongIterator, LongListIterator, ObjectBidirectionalIterator<Long>, ObjectIterator<Long>, Serializable, Cloneable, Iterator<Long>, ListIterator<Long>

Enclosing class:

LongIterators

public static class LongIterators.EmptyIterator
extends AbstractLongListIterator
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.

Methods

Modifier and Type	Method and Description
int	back(int n) This method just iterates the type-specific version of AbstractLongBidirectionalIterator.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()
long	nextLong() Delegates to the corresponding generic method.
int	previousIndex()
long	previousLong() Delegates to the corresponding generic method.
int	skip(int n) This method just iterates the type-specific version of AbstractLongIterator.next() for at most n times, stopping if Iterator.hasNext() becomes false.
