public static class ObjectBigListIterators.EmptyBigListIterator<K>
extends AbstractObjectBigListIterator<K>
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<K>

hasPrevious

public boolean hasPrevious()
Description copied from interface: BidirectionalIterator
Returns whether there is a previous element.

Specified by:
hasPrevious in interface BidirectionalIterator<K>
Returns:
whether there is a previous element.
See Also:
ListIterator.hasPrevious()

next

public K next()
Specified by:
next in interface Iterator<K>

previous

public K previous()
Description copied from interface: BidirectionalIterator
Returns the previous element from the collection.

Specified by:
previous in interface BidirectionalIterator<K>
Returns:
the previous element from the collection.
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<K>
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<K>
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: AbstractObjectBigListIterator
This method just iterates the type-specific version of Iterator.next() for at most n times, stopping if Iterator.hasNext() becomes false.

Specified by:
skip in interface BigListIterator<K>
Overrides:
skip in class AbstractObjectBigListIterator<K>
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: AbstractObjectBigListIterator
This method just iterates the type-specific version of BidirectionalIterator.previous() for at most n times, stopping if BidirectionalIterator.hasPrevious() becomes false.

Overrides:
back in class AbstractObjectBigListIterator<K>

clone

public Object clone()
Overrides:
clone in class Object
