| Constructor Summary | |
ListIteratorCharListIterator(java.util.ListIterator iterator)
Creates an CharListIterator wrapping
the specified ListIterator. |
|
| Method Summary | |
void |
add(char 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. |
char |
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. |
char |
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(char element)
Replaces in my underlying collection the last element returned by next() or previous()
with the specified value (optional operation). |

the given iterator is null,
returns null.

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