Public Methods
public abstract void addListener (IEventListener listener)
Register a listener. The implementor may allow duplicates.
Parameters
| listener | a listener of events generated by this source |
|---|
public abstract int countListeners ()
Get the numbers of objects listening to this event source.
Returns
- the number of listeners
public abstract IEventSource getParentSource ()
Get the parent source.
Returns
- the parent source, or null if none
public abstract void insertListener (int index, IEventListener listener)
Insert a listner at the given position.
public abstract void notifyListeners (IEvent e)
Notify listeners that an event has occurred.
Parameters
| e | the event to be propagated |
|---|
public abstract boolean removeListener (IEventListener listener)
Unregister a listener. If the implementor allows duplicates in addListener(), it should deal with those consistently.
Parameters
| listener | the listener to be removed |
|---|
Returns
- true if the listener was successfully removed, false
public abstract void setParentSource (IEventSource parentSource)
Set a parent source.
Parameters
| parentSource | the optional parent source |
|---|
