Package org.cometd.annotation
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);
