Returns
WebSocketSubject<R>
multiplex(subMsg: () => any, unsubMsg: () => any, messageFilter: (value: T) => boolean)
Creates an Observable, that when subscribed to, sends a message, defined by the subMsg function, to the server over the socket to begin a subscription to data over that socket. Once data arrives, the messageFilter argument will be used to select the appropriate data for the resulting Observable. When teardown occurs, either due to unsubscription, completion, or error, a message defined by the unsubMsg argument will be sent to the server over the WebSocketSubject.
Parameters
| subMsg | A function to generate the subscription message to be sent to the server. This will still be processed by the serializer in the WebSocketSubject's config. (Which defaults to JSON serialization) |
| unsubMsg | A function to generate the unsubscription message to be sent to the server at teardown. This will still be processed by the serializer in the WebSocketSubject's config. |
| messageFilter | A predicate for selecting the appropriate messages from the server for the output stream. |
unsubscribe()
