- Functional Interface:
- This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterface public interface ConfirmCallbackImplement this interface in order to be notified of Confirm events. Acks represent messages handled successfully; Nacks represent messages lost by the broker. Note, the lost messages could still have been delivered to consumers, but the broker cannot guarantee this. Prefer this interface over
ConfirmListenerfor a lambda-oriented syntax.
