SendAcknowledgementHandler (ActiveMQ Artemis Website 2.38.0 API)

```
public interface SendAcknowledgementHandler
```
A SendAcknowledgementHandler notifies a client when a message sent asynchronously has been received by the server.
If the session is not blocking when sending durable or non-durable messages, the session can set a SendAcknowledgementHandler to be notified later when the messages has been received by the server. The method sendAcknowledged(Message) will be called with the message that was sent asynchronously.
The rate of notification can be controlled through ServerLocator.setConfirmationWindowSize(int).
Notice that this notification will only take place if ConfirmationWindowSize is set to a positive value at ServerLocator.setConfirmationWindowSize(int).
