Class ObserverMethodImpl<T,X>

java.lang.Object

org.jboss.weld.event.ObserverMethodImpl<T,X>

All Implemented Interfaces:

ObserverMethod<T>

public class ObserverMethodImpl<T,X>
extends java.lang.Object
implements ObserverMethod<T>

Reference implementation for the ObserverMethod interface, which represents an observer method. Each observer method has an event type which is the class of the event object being observed, and event binding types that are annotations applied to the event parameter to narrow the event notifications delivered.
