public static class LongIterators.EmptyIterator extends AbstractLongListIterator implements java.io.Serializable, java.lang.Cloneable
This class may be useful to implement your own in case you subclass a type-specific iterator.
Modifier and Type | Method and Description |
---|---|
int |
back(int 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.
|
int |
nextIndex() |
long |
nextLong()
Delegates to the corresponding generic method.
|
int |
previousIndex() |
long |
previousLong()
Delegates to the corresponding generic method.
|
int |
skip(int n)
This method just iterates the type-specific version of
AbstractLongIterator.next() for at most
n times, stopping if Iterator.hasNext() becomes false. |
