Class ClientAnnotationProcessor

java.lang.Object
  org.cometd.java.annotation.ClientAnnotationProcessor

public class ClientAnnotationProcessor
extends Object

Processes annotations in client-side service objects.

Service objects must be annotated with Service at class level to be processed by this processor, for example:

 @Service
 public class MyService
 {
     @Listener(Channel.META_CONNECT)
     public void metaConnect(Message message)
     {
         // Do something
     }
 }
 

The processor is used in this way:

 ClientSession bayeux = ...;
 ClientAnnotationProcessor processor = ClientAnnotationProcessor.get(bayeux);
 MyService s = new MyService();
 processor.process(s);

Method Detail

process

public boolean process(Object bean)

Processes dependencies annotated with Session, and callbacks annotated with Listener and Subscription.

Parameters:

bean - the annotated service instance

Returns:

true if at least one dependency or callback has been processed, false otherwise

processPostConstruct

public boolean processPostConstruct(Object bean)

Processes lifecycle methods annotated with PostConstruct.

Parameters:

bean - the annotated service instance

Returns:

true if at least one lifecycle method has been invoked, false otherwise

deprocess

public boolean deprocess(Object bean)

Performs the opposite processing done by process(Object) on callbacks methods annotated with Listener and Subscription, and on lifecycle methods annotated with PreDestroy.

Parameters:

bean - the annotated service instance

Returns:

true if at least one deprocessing has been performed, false otherwise

deprocessCallbacks

public boolean deprocessCallbacks(Object bean)

Deconfigures callbacks annotated with Listener and Subscription.

Parameters:

bean - the annotated service instance

Returns:

true if the at least one callback has been deconfigured

public boolean processPreDestroy(Object bean)

Processes lifecycle methods annotated with PreDestroy.

Parameters:

bean - the annotated service instance

Returns:

true if at least one lifecycle method has been invoked, false otherwise
