- All Implemented Interfaces:
- BidirectionalIterator<Long>, LongBidirectionalIterator, LongIterator, LongListIterator, ObjectBidirectionalIterator<Long>, ObjectIterator<Long>, Serializable, Cloneable, Iterator<Long>, ListIterator<Long>
- Enclosing class:
- LongIterators
public static class LongIterators.EmptyIterator
- extends AbstractLongListIterator
- implements Serializable, Cloneable
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.

skip
public int skip(int n)
- Description copied from class:
AbstractLongIterator
- 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 LongIterator
- Specified by:
skip
in interface ObjectIterator<Long>
- Overrides:
skip
in class AbstractLongIterator
- Parameters:
n
- the number of elements to skip.
- Returns:
- the number of elements actually skipped.
- See Also:
Iterator.next()
back
public int back(int n)
- Description copied from class:
AbstractLongBidirectionalIterator
- This method just iterates the type-specific version of
AbstractLongBidirectionalIterator.previous()
for
at most n
times, stopping if BidirectionalIterator.hasPrevious()
becomes false.
- Specified by:
back
in interface LongBidirectionalIterator
- Specified by:
back
in interface ObjectBidirectionalIterator<Long>
- Overrides:
back
in class AbstractLongBidirectionalIterator
- Parameters:
n
- the number of elements to skip back.
