subscribe

public WebSocketReply subscribe(WebSocketDecodeContext ctx,

                         throws WebSocketException

Registers for updates on any processor or client. Sends the current set of processor, and clients (in that order) to the requester.

Calling this multiple times, will cause the current set of data to be sent again. Further updates will still arrive one-time only.

Specified by:

subscribe in interface WebSocketResource

Throws:

WebSocketException
