Interface ConfirmCallback

  • 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 ConfirmCallback
    Implement 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 ConfirmListener for a lambda-oriented syntax.
