Class ClientAnnotationProcessor

  • public class ClientAnnotationProcessor
extends AnnotationProcessor

    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);

        Overrides:
        processPostConstruct in class AnnotationProcessor
        Parameters:
        bean - the annotated service instance
        Returns:

      • deprocess

        public boolean deprocess​(java.lang.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
