it.unimi.dsi.fastutil.longs.LongIterators.EmptyIterator
public static class LongIterators.EmptyIterator
A class returning no elements and a type-specific iterator interface.
This class may be useful to implement your own in case you subclass a type-specific iterator.
Method Summary | |
---|---|
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. |
