Annotation Interface HandleEvent

@Documented @Retention(RUNTIME) @Target({METHOD,CONSTRUCTOR}) @HandleMessage(EVENT) public @interface HandleEvent
Marks a method or constructor as an event handler for incoming messages of type MessageType.EVENT.

This annotation is used to designate methods that should be invoked when an event message is received. It can be applied to instance methods or constructors. Constructors or static methods may be used for initializing stateful handlers (see Stateful) in response to creation events.

Event handlers typically return void, as event processing is usually side-effect driven and does not produce a result to be returned or published.

Example:


 @HandleEvent
 void on(UserCreated event) {
     //do something with the event
 }
