ListIteratorLongListIterator(java.util.ListIterator iterator)
Creates an LongListIterator wrapping
the specified ListIterator. |
|
| Method Summary | |
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. |

hasPrevious()
Returns true iff I have more elements
when traversed in the reverse direction. |

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 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 previous(), or
-1 if I have no previous element. |
void |
remove()
Removes from my underlying collection the last element returned by next() or previous()
(optional operation). |
void |
set(long element)
Replaces in my underlying collection the last element returned by next() or previous()
with the specified value (optional operation). |

LongListIteratorLongListIterator.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().
