java.lang.Object

org.richfaces.application.ServiceTracker

public final class ServiceTracker
extends Object

Tracker class to provide access to various framework implementation services. Examples of such services are: SkinFactory, TBD.

This class managess application-scoped service factories that are stored in the map with Thread.currentThread() Context classloader as the key. Therefore, there is only one instance per JEE application in the current JVM.

actuall cal for the service instance delegated to the current factory

Note: in initial state this class is not synchronized and presumes that all modification operations are done in a context of single-thread (in JSF initialization listener).
