org.apache.webbeans.event
Class ObserverMethodImpl<T>

java.lang.Object
  org.apache.webbeans.event.ObserverMethodImpl<T>

Type Parameters:

T - event type

All Implemented Interfaces:

javax.enterprise.inject.spi.ObserverMethod<T>

public class ObserverMethodImpl<T>
extends java.lang.Object
implements javax.enterprise.inject.spi.ObserverMethod<T>

Defines observers that are declared in observer methods.

Example:

  public class X {
      
      public void afterLoggedIn(@Observes @Current LoggedInEvent event)
      {
          .....
      }
  }
