Parameters:

wrapper - The component that will be the source of events that we fire

Method Detail

getWrapper

public Wrapper getWrapper()

Return the Wrapper with which we are associated.

addInstanceListener

public void addInstanceListener(InstanceListener listener)

Add a lifecycle event listener to this component.

Parameters:

listener - The listener to add

filter - The relevant Filter for this event

fireInstanceEvent

public void fireInstanceEvent(String type,
                              Filter filter,
                              Throwable exception)

Notify all lifecycle event listeners that a particular event has occurred for this Container. The default implementation performs this notification synchronously using the calling thread.

Parameters:

type - Event type

filter - The relevant Filter for this event

exception - Exception that occurred

fireInstanceEvent

public void fireInstanceEvent(String type,
                              Filter filter,
