Public Methods

Method Description
BroadcastHandler ( IMessagingControl messagingControl, ISendToFilterCallback callback ) : System.Linq

Constructor.

OnActive ( string topicPath, IRegisteredHandler registeredHandler ) : void

Called when the handler has been successfully registered with the server. A session can register a single handler of each type for a given branch of the topic tree. If there is already a handler registered for the topic path the operation will fail, registeredHandler will be closed, and the session error handler will be notified. To change the handler, first close the previous handler.

OnClose ( string topicPath ) : void

Called if the handler is closed. This happens if the call to register the handler fails, or the handler is unregistered.

OnMessage ( SessionId sessionId, string topicPath, IContent content, IReceiveContext context ) : void

Receives content sent from a session via a topic.
