All Implemented Interfaces:

BidirectionalIterator<Double>, BigListIterator<Double>, DoubleBidirectionalIterator, DoubleBigListIterator, DoubleIterator, ObjectBidirectionalIterator<Double>, ObjectIterator<Double>, Serializable, Cloneable, Iterator<Double>

Enclosing class:

DoubleBigListIterators

public static class DoubleBigListIterators.EmptyBigListIterator
extends AbstractDoubleBigListIterator
implements Serializable, Cloneable

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

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

Method Summary

long	back(long 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.
long	nextIndex() Returns the index of the element that would be returned by a subsequent call to next.
double	previousDouble() Delegates to the corresponding generic method.
long	previousIndex() Returns the index of the element that would be returned by a subsequent call to previous.
long	skip(long n) This method just iterates the type-specific version of AbstractDoubleIterator.next() for at most n times, stopping if Iterator.hasNext() becomes false.

Method Detail

hasNext

public boolean hasNext()

Specified by:

hasNext in interface Iterator<Double>

hasPrevious

public boolean hasPrevious()

Description copied from interface: BidirectionalIterator

Returns whether there is a previous element.

Specified by:

hasPrevious in interface BidirectionalIterator<Double>

Returns:

whether there is a previous element.

See Also:

ListIterator.hasPrevious()

nextDouble

public double nextDouble()

Description copied from class: AbstractDoubleIterator

Delegates to the corresponding generic method.

Specified by:

nextDouble in interface DoubleIterator

Overrides:

nextDouble in class AbstractDoubleIterator

Returns:

the next element in the iteration.

See Also:

Iterator.next()

previousDouble

public double previousDouble()

Description copied from class: AbstractDoubleBidirectionalIterator

Delegates to the corresponding generic method.

Specified by:

previousDouble in interface DoubleBidirectionalIterator

Overrides:

previousDouble in class AbstractDoubleBidirectionalIterator

Returns:

the previous element in the iteration.

See Also:

ListIterator.previous()

nextIndex

public long nextIndex()

Description copied from interface: BigListIterator

Returns the index of the element that would be returned by a subsequent call to next. (Returns list size if the list iterator is at the end of the list.)

Specified by:

nextIndex in interface BigListIterator<Double>

Returns:

the index of the element that would be returned by a subsequent call to next, or list size if list iterator is at end of list.

See Also:

ListIterator.nextIndex()

previousIndex

public long previousIndex()

Description copied from interface: BigListIterator

Returns the index of the element that would be returned by a subsequent call to previous. (Returns -1 if the list iterator is at the beginning of the list.)

Specified by:

previousIndex in interface BigListIterator<Double>

Returns:

the index of the element that would be returned by a subsequent call to previous, or -1 if list iterator is at beginning of list.

See Also:

ListIterator.previousIndex()

skip

public long skip(long n)

Description copied from class: AbstractDoubleBigListIterator

This method just iterates the type-specific version of AbstractDoubleIterator.next() for at most n times, stopping if Iterator.hasNext() becomes false.

Specified by:

skip in interface BigListIterator<Double>

Overrides:

skip in class AbstractDoubleBigListIterator

Parameters:

n - the number of elements to skip.

Returns:

the number of elements actually skipped.

back

public long back(long n)

Description copied from class: AbstractDoubleBigListIterator

This method just iterates the type-specific version of AbstractDoubleBidirectionalIterator.previous() for at most n times, stopping if BidirectionalIterator.hasPrevious() becomes false.

Overrides:

back in class AbstractDoubleBigListIterator

clone

public Object clone()

Overrides:

clone in class Object
