LongBigListIterators

public static class LongBigListIterators.EmptyBigListIterator
extends AbstractLongBigListIterator
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 AbstractLongBidirectionalIterator.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.
 long nextIndex()
          Returns the index of the element that would be returned by a subsequent call to next.
 long nextLong()
          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 previousLong()
          Delegates to the corresponding generic method.
 long skip(long n)
          This method just iterates the type-specific version of AbstractLongIterator.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<java.lang.Long>

hasPrevious

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

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

nextLong

public long nextLong()
Description copied from class: AbstractLongIterator
Delegates to the corresponding generic method.

Specified by:
nextLong in interface LongIterator
Overrides:
nextLong in class AbstractLongIterator
Returns:
the next element in the iteration.
See Also:
Iterator.next()

previousLong

public long previousLong()
Description copied from class: AbstractLongBidirectionalIterator
Delegates to the corresponding generic method.

Specified by:
previousLong in interface LongBidirectionalIterator
Overrides:
previousLong in class AbstractLongBidirectionalIterator
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<java.lang.Long>
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<java.lang.Long>
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: AbstractLongBigListIterator
This method just iterates the type-specific version of AbstractLongIterator.next() for at most n times, stopping if Iterator.hasNext() becomes false.

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

Overrides:
back in class AbstractLongBigListIterator

clone

public java.lang.Object clone()
Overrides:
clone in class java.lang.Object
