Public Constructors

public JebEventSource ()

Create an event with a null parent source.

public JebEventSource (IEventSource parentSource)

Create an event source and hook it to a parent source. When this source notifies its observers of an event, the "parent source" will also be notified (regardless of the "parent source" being a listener of that observable).

Parameters
parentSource source that generated the event

Public Methods

public void addListener (IEventListener listener)

Register a listener. The listener is appended to the existing list of listeners. The implementor may allow duplicates.

Parameters
listener a listener of events generated by this source

public int countListeners ()

Get the numbers of objects listening to this event source.

Returns
  • the number of listeners

public List<IEventListener> getListeners ()

Get a copy of the list of listeners.

public IEventSource getParentSource ()

Get the parent source.

Returns
  • the parent source, or null if none

public void insertListener (int index, IEventListener listener)

Register a listener. The implementor may allow duplicates.

Parameters
index insertion point
listener a listener of events generated by this source

public void notifyListeners (JebEvent e, boolean notifyParent)

public void notifyListeners (IEvent e)

Notify listeners that an event has occurred.

Parameters
e the event to be propagated

public void notifyListeners (JebEvent e)

public void 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

public void setParentSource (IEventSource parentSource)

Set a parent source.

Parameters
parentSource the optional parent source
