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 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
