## Interface SendAcknowledgementHandler

-     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)`.
