public void |
add(Object o)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.)

public ListIterator |
getListIterator()Returns the wrapped list iterator. |
|
public 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.)
|
|
public 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.)
|
|
public Object |
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.)
|
|
public 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.)
|
|
public void |
set(Object o)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 have been called after the last call to next or
previous.

class ObservableList.ObservableIterator |
getDelegate, hasNext, next, remove |
Creates an observable list iterator.
iterDelegate - the backing list iteratorindex - the starting index 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.)
add method is
not supported by this list iteratore - the element to insertReturns the wrapped list iterator.
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.)
true if the list iterator has more elements when
traversing the list in the reverse directionReturns 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.)
next, or list size if the list
iterator is at the end of the list 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 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.)
previous, or -1 if the list
iterator is at the beginning of the list 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 have been called after the last call to next or
previous.
