All Superinterfaces:

XLongIterator
```
public interface XLongListIterator
extends XLongIterator
```
A list based iterator for primitive longs that support forwards and backwards navigation

Method Summary

Methods
Modifier and Type	Method and Description
`void`	`add(long e)` Inserts the specified element into the list (optional operation).
`boolean`	`hasNext()` Returns `true` if this list iterator has more elements when traversing the list in the forward direction.
`boolean`	`hasPrevious()` Returns `true` if this list iterator has more elements when traversing the list in the reverse direction.
`long`	`next()` Returns the next element in the list and advances the cursor position.
`int`	`nextIndex()` Returns the index of the element that would be returned by a subsequent call to `next()`.
`long`	`previous()` Returns the previous element in the list and moves the cursor position backwards.
`int`	`previousIndex()` Returns the index of the element that would be returned by a subsequent call to `previous()`.
`void`	`remove()` Removes from the list the last element that was returned by `next()` or `previous()` (optional operation).
`void`	`set(long e)` Replaces the last element returned by `next()` or `previous()` with the specified element (optional operation).

- Method Detail
  - hasNext
```
boolean hasNext()
```
    Returns true if this list iterator has more elements when traversing the list in the forward direction. (In other words, returns true if next() would return an element rather than throwing an exception.)
    
    Specified by:
    
    hasNext in interface XLongIterator
    
    Returns:
    true if the list iterator has more elements when traversing the list in the forward direction
  - next
```
long next()
```
    Returns the next element in the list and advances the cursor position. This method may be called repeatedly to iterate through the list, or intermixed with calls to previous() to go back and forth. (Note that alternating calls to next and previous will return the same element repeatedly.)
    
    Specified by:
    
    next in interface XLongIterator
    
    Returns:
    the next element in the list
    
    Throws:
    
    NoSuchElementException - if the iteration has no next element
  - hasPrevious
```
boolean hasPrevious()
```
    Returns true if this list iterator has more elements when traversing the list in the reverse direction. (In other words, returns true if previous() would return an element rather than throwing an exception.)
    
    Returns:
    true if the list iterator has more elements when traversing the list in the reverse direction
  - previous
```
long previous()
```
    Returns the previous element in the list and moves the cursor position backwards. This method may be called repeatedly to iterate through the list backwards, or intermixed with calls to next() to go back and forth. (Note that alternating calls to next and previous will return the same element repeatedly.)
    
    Returns:
    the previous element in the list
    
    Throws:
    
    NoSuchElementException - if the iteration has no previous element
  - nextIndex
```
int nextIndex()
```
    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.)
    
    Returns:
    the index of the element that would be returned by a subsequent call to next, or list size if the list iterator is at the end of the list
  - previousIndex
```
int previousIndex()
```
    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.)
    
    Returns:
    the index of the element that would be returned by a subsequent call to previous, or -1 if the list iterator is at the beginning of the list
  - remove
```
void remove()
```
    Removes from the list the last element that was returned by next() or previous() (optional operation). This call can only be made once per call to next or previous. It can be made only if add(long) has not been called after the last call to next or previous.
    
    Specified by:
    
    remove in interface XLongIterator
    
    Throws:
    
    UnsupportedOperationException - if the remove operation is not supported by this list iterator
    
    IllegalStateException - if neither next nor previous have been called, or remove or add have been called after the last call to next or previous
  - set
```
void set(long e)
```
    Replaces the last element returned by next() or previous() with the specified element (optional operation). This call can be made only if neither remove() nor add(long) have been called after the last call to next or previous.
    
    Parameters:
    e - the element with which to replace the last element returned by next or previous
    
    Throws:
    
    IllegalStateException - if neither next nor previous have been called, or remove or add have been called after the last call to next or previous
  - add
```
void add(long e)
```
    Inserts the specified element into the list (optional operation). The element is inserted immediately before the element that would be returned by next(), if any, and after the element that would be returned by previous(), if any. (If the list contains no elements, the new element becomes the sole element on the list.) The new element is inserted before the implicit cursor: a subsequent call to next would be unaffected, and a subsequent call to previous would return the new element. (This call increases by one the value that would be returned by a call to nextIndex or previousIndex.)
    
    Parameters:
    e - the element to insert
