All Implemented Interfaces:

BidirectionalIterator<Double>, DoubleBidirectionalIterator, DoubleIterator, DoubleListIterator, ObjectBidirectionalIterator<Double>, ObjectIterator<Double>, Serializable, Cloneable, Iterator<Double>, ListIterator<Double>

Enclosing class:

DoubleIterators

public static class DoubleIterators.EmptyIterator
extends AbstractDoubleListIterator
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.

DoubleIterators.EmptyIterator()

Method Summary

int	back(int n) This method just iterates the type-specific version of AbstractDoubleBidirectionalIterator.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.
double	nextDouble() Delegates to the corresponding generic method.
int	nextIndex()
double	previousDouble() Delegates to the corresponding generic method.
int	previousIndex()
int	skip(int n) This method just iterates the type-specific version of AbstractDoubleIterator.next() for at most n times, stopping if Iterator.hasNext() becomes false.
