Class 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);

      • process

        public boolean process​(Object bean)
        Processes dependencies annotated with Session, callbacks annotated with Listener and Subscription and lifecycle methods annotated with PostConstruct.
        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)
        Performs the opposite processing done by processCallbacks(Object) on callback methods annotated with Listener and Subscription.
        Parameters:
        bean - the annotated service instance
        Returns:
        true if the at least one callback has been deprocessed

      • processPreDestroy

        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
