public interface EventQueueManagerOperations
extends InterceptorManager

EventQueueManager is a singleton, with which application code registers, unregisters and retrieves event listeners. Application code is supposed to bootstrap this singleton as follows,

      try {
        InterceptorManagerControl control =
          InterceptorManagerControlHelper.narrow (
            orb.resolve_initial_references( "VisiBrokerInterceptorControl")
          );

        EventQueueManager queue_manager =
         (EventQueueManager) control.get_manager( "EventQueue");

        queue_manager.register_listener (
          new MyConnEventListener(),
          EventType.CONN_EVENT_TYPE
        );
      }
      catch( Exception e) {
        ...
      }
