void |
add(long element)
Inserts the specified element into my underlying collection (optional operation). |
boolean |
hasNext()
Returns true iff I have more elements
when traversed in the forward direction. |
boolean |
hasPrevious()
Returns true iff I have more elements
when traversed in the reverse direction. |
long |
next()
Returns the next element in me when traversed in the forward direction. |
int |
nextIndex()
Returns the index of the element that would be returned by a subsequent call to LongListIterator.next() , or the number
of elements in my iteration if I have no next element. |
long |
previous()
Returns the next element in me when traversed in the reverse direction. |
int |
previousIndex()
Returns the index of the element that would be returned by a subsequent call to LongListIterator.previous() , or
-1 if I have no previous element. |
void |
remove()
Removes from my underlying collection the last element returned by LongListIterator.next() or LongListIterator.previous()
(optional operation). |
void |
set(long element)
Replaces in my underlying collection the last element returned by LongListIterator.next() or LongListIterator.previous()
with the specified value (optional operation). |

public void add(long element)
LongListIterator
LongListIterator.next()
, if any,
and immediately after the next element that would have been
returned by LongListIterator.previous()
, if any.
The new element is inserted immediately before the implied
cursor. A subsequent call to LongListIterator.previous()
will return
the added element, a subsequent call to LongListIterator.next()
will
be unaffected. This call increases by one the value that
would be returned by a call to LongListIterator.nextIndex()
or
LongListIterator.previousIndex()
.
