Class ListenerHolder

java.lang.Object

org.eclipse.jetty.util.component.AbstractLifeCycle

org.eclipse.jetty.servlet.BaseHolder<java.util.EventListener>

org.eclipse.jetty.servlet.ListenerHolder

All Implemented Interfaces:

org.eclipse.jetty.util.component.Dumpable, org.eclipse.jetty.util.component.LifeCycle

public class ListenerHolder
extends BaseHolder<java.util.EventListener>

ListenerHolder Specialization of BaseHolder for servlet listeners. This allows us to record where the listener originated - web.xml, annotation, api etc.

Method Detail

getListener

public java.util.EventListener getListener()

setListener

public void setListener(java.util.EventListener listener)

Set an explicit instance. In this case, just like ServletHolder and FilterHolder, the listener will not be introspected for annotations like Resource etc.

Parameters:

listener - The listener instance

             throws java.lang.Exception

Overrides:

doStart in class BaseHolder<java.util.EventListener>

Throws:

java.lang.Exception

createInstance

protected java.util.EventListener createInstance()
                                          throws java.lang.Exception

Overrides:

createInstance in class BaseHolder<java.util.EventListener>

Throws:

java.lang.Exception

doStop

public void doStop()
            throws java.lang.Exception

Overrides:

doStop in class BaseHolder<java.util.EventListener>

Throws:
