All Implemented Interfaces:

BidirectionalIterator<java.lang.Long>, LongBidirectionalIterator, LongIterator, LongListIterator, ObjectBidirectionalIterator<java.lang.Long>, ObjectIterator<java.lang.Long>, java.io.Serializable, java.lang.Cloneable, java.util.Iterator<java.lang.Long>, java.util.ListIterator<java.lang.Long>

Enclosing class:

LongIterators
```
public static class LongIterators.EmptyIterator
extends AbstractLongListIterator
implements java.io.Serializable, java.lang.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.

Method Summary

All Methods Instance Methods Concrete Methods
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.
