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.
