Class TimingServiceListener

java.lang.Object

org.jboss.msc.service.AbstractServiceListener<java.lang.Object>

org.jboss.msc.service.TimingServiceListener

All Implemented Interfaces:

ServiceListener<java.lang.Object>

public final class TimingServiceListener
extends AbstractServiceListener<java.lang.Object>
implements ServiceListener<java.lang.Object>

A service listener which times service start. The timing starts from the moment the listener is created and ends when the last service is batched and the services are all started.

Method Detail

listenerAdded

public void listenerAdded(ServiceController<? extends java.lang.Object> serviceController)

The listener has been added to a controller.

Specified by:

listenerAdded in interface ServiceListener<java.lang.Object>

Overrides:

listenerAdded in class AbstractServiceListener<java.lang.Object>

Parameters:
