Specified by:

removeListener in interface EventSource

Throws:

EventSourceException

removeAllListeners

getListeners

public java.util.List getListeners()

Description copied from interface: EventSource

Obtain those listeners that are registered for all event classes (i.e., those that use the addListener(EventObjectListener) method).

Specified by:

getListeners in interface EventSource

getAllListeners

public java.util.List getAllListeners()

Description copied from interface: EventSource

Obtain the complete list of listeners that are registered. The resulting list contains no duplicates.

Specified by:

getAllListeners in interface EventSource

getListeners

public java.util.List getListeners(java.lang.Class eventClass)

Description copied from interface: EventSource

Obtain the listeners for the specified event class

Specified by:

getListeners in interface EventSource

addListeners

public void addListeners(AbstractEventSource eventSource)
                  throws EventSourceException

Add to this event source all the listeners of the specified AbstractEventSource. This implementation is careful not to get a lock on both objects at once.

Throws:

EventSourceException
