public class SendResumeRequest
extends WritableRequest
implements WorkerRequest

Send to a worker a signal to resume sending messages to sender worker. This type of request is used in adaptive credit-based flow control, where a worker (W) may assign credit value of 0 to some worker (U), so that U would stop sending messages to W. Later on, W may want to notify U to continue sending messages to W. Along with the resume signal, W also announces a new credit value to U.
