Class ServerAnnotationProcessor

java.lang.Object

org.cometd.annotation.ServerAnnotationProcessor

public class ServerAnnotationProcessor
extends Object

Processes annotations in server-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
 {
     @Session
     private ServerSession session;

     @Configure("/foo")
     public void configureFoo(ConfigurableServerChannel channel)
     {
         channel.setPersistent(...);
         channel.addListener(...);
         channel.addAuthorizer(...);
     }

     @Listener("/foo")
     public void handleFooMessages(ServerSession remote, ServerMessage.Mutable message)
     {
         // Do something
     }
 }
 

The processor is used in this way:

 BayeuxServer bayeux = ...;
 ServerAnnotationProcessor processor = ServerAnnotationProcessor.get(bayeux);
 MyService s = new MyService();
 processor.process(s);

Method Detail

process

public boolean process(Object bean)

Processes dependencies annotated with Inject and Session, lifecycle methods annotated with PostConstruct, and callback methods annotated with Listener and Subscription.

Parameters:

bean - the annotated service instance

Returns:

true if the bean contains at least one annotation that has been processed, false otherwise

processConfigurations

public boolean processConfigurations(Object bean)

Processes the methods annotated with Configure

Parameters:

bean - the annotated service instance

Returns:

true if at least one annotated configure has been processed, false otherwise

processDependencies

public boolean processDependencies(Object bean)

Processes the dependencies annotated with Inject and Session.

Parameters:

bean - the annotated service instance

Returns:

true if at least one annotated dependency 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

processCallbacks

public boolean processCallbacks(Object bean)

Processes the callbacks annotated with Listener and Subscription.

Parameters:

bean - the annotated service instance

Returns:

true if at least one annotated callback has been processed, 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

process(Object)

deprocessCallbacks

public boolean deprocessCallbacks(Object bean)

Performs the opposite processing done by processCallbacks(Object) on callback methods annotated with Listener and Subscription.

Parameters:

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
