Interface SendCallback

public interface SendCallback

This interface allows implementors to perform logic just before and just after the send. For asynchronous commands there may be a time lag between queuing and sending. And, the send may be performed on a different thread than the queuing. The main purpose of this is to provide a chance to set thread-local information that can affect the serialization logic.
