Enclosing class:

ObjectBigListIterators

public static class ObjectBigListIterators.EmptyBigListIterator<K>
extends AbstractObjectBigListIterator<K>
implements java.io.Serializable, java.lang.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 BidirectionalIterator.previous() for at most n times, stopping if BidirectionalIterator.hasPrevious() becomes false.
java.lang.Object	clone()
boolean	hasNext()
boolean	hasPrevious() Returns whether there is a previous element.
K	next()
long	nextIndex() Returns the index of the element that would be returned by a subsequent call to next.
K	previous() Returns the previous element from the collection.
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 Iterator.next() for at most n times, stopping if Iterator.hasNext() becomes false.

Method Detail

hasNext

public boolean hasNext()

Specified by:

hasNext in interface java.util.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 java.util.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 java.lang.Object clone()

Overrides:

clone in class java.lang.Object
