Class EventMessenger

java.lang.Object

ch.rasc.wampspring.EventMessenger

public class EventMessenger
extends Object

A messenger that allows the calling code to send EventMessages back to the client. This is a spring bean that can be autowired into any other spring bean and allows any part of the application to send messages back to the client e.g.

 @Service
 public class MyService {
        @Autowired
        EventMessenger eventMessenger;
 
        public void doSomething() {
                eventMessenger.sendToAll("aTopic", "the message");
        }
 }
 

This is very similar to the org.springframework.messaging.simp.SimpMessagingTemplate class from Spring's STOMP support.
