All Implemented Interfaces:

BidirectionalIterator<Character>, CharBidirectionalIterator, CharIterator, CharListIterator, ObjectBidirectionalIterator<Character>, ObjectIterator<Character>, Serializable, Cloneable, Iterator<Character>, ListIterator<Character>

Enclosing class:

CharIterators

public static class CharIterators.EmptyIterator
extends AbstractCharListIterator
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.

CharIterators.EmptyIterator()

Method Summary

int	back(int n) This method just iterates the type-specific version of AbstractCharBidirectionalIterator.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.
char	nextChar() Delegates to the corresponding generic method.
int	nextIndex()
char	previousChar() Delegates to the corresponding generic method.
int	previousIndex()
int	skip(int n) This method just iterates the type-specific version of AbstractCharIterator.next() for at most n times, stopping if Iterator.hasNext() becomes false.
