Class EmptyReply


  • public final class EmptyReply
    extends Reply
    The empty reply is the only concrete implementation of a message that is offered by the MessageBus. It is used to generate replies to events that occur within the messagebus, and since the messagebus by design knows nothing about the messages that have been implemented by the users it requires a class such as this.
