move

public 
Object move(int oldIndex,
                   int newIndex)
Description copied from class: AbstractObservableList
Moves the element located at oldIndex to newIndex. This method is equivalent to calling add(newIndex, remove(oldIndex)).

Subclasses should override this method to deliver list change notification for the remove and add operations in the same ListChangeEvent, as this allows ListDiff.accept(ListDiffVisitor) to recognize the operation as a move.

Specified by:
move in interface IObservableList
Overrides:
move in class AbstractObservableList
Parameters:
oldIndex - the element's position before the move. Must be within the range 0 <= oldIndex < size().
newIndex - the element's position after the move. Must be within the range 0 <= newIndex < size().
Returns:
the element that was moved.
See Also:
ListDiffVisitor.handleMove(int, int, Object), ListDiff.accept(ListDiffVisitor)

isStale

public boolean isStale()
Description copied from interface: IObservable
Returns whether the state of this observable is stale and is expected to change soon. A non-stale observable that becomes stale will notify its stale listeners. A stale object that becomes non-stale does so by changing its state and notifying its change listeners, it does not notify its stale listeners about becoming non-stale. Clients that do not expect asynchronous changes may ignore staleness of observable objects.

Specified by:
isStale in interface IObservable
Overrides:
isStale in class AbstractObservableList
Returns:
true if this observable's state is stale and will change soon.

dispose

public void dispose()
Description copied from interface: IObservable
Disposes of this observable object, removing all listeners registered with this object, and all listeners this object might have registered on other objects.

Specified by:
