Method Detail

detectDeadConnections

public static void detectDeadConnections()

Starts a thread which checks periodically for dead connections and force them to re-connect. IF AND ONLY IF a thread isn't already running to do this

obtainConnectionFor

protected com.datasift.client.stream.DataSiftConnection obtainConnectionFor(Stream stream)

onError

public ConnectionManager onError(ErrorListener listener)

Subscribes a callback to listen for exceptions that may occur during streaming. When exceptions occur it is unlikely we'll know which stream/subscription caused the exception so instead of notifying all stream subscribers of the same exception this provides a way to list the error just once

Parameters:

listener - an error callback

onStreamEvent

public void onStreamEvent(StreamEventListener streamEventListener)

subscribe

public ConnectionManager subscribe(StreamSubscription subscription)

unsubscribe

public ConnectionManager unsubscribe(Stream stream)
