    • Method Detail

      • message

        <E> Message<E> message()
                        throws ClientException
        Decode the Delivery payload and return an Message object.

        If the incoming message carried any delivery annotations they can be accessed via the annotations() method. Re-sending the returned message will not also send the incoming delivery annotations, the sender must include them in the Sender.send(Message, Map) call if they are to be forwarded onto the next recipient.

        Calling this message claims the payload of the delivery for the returned Message and excludes use of the rawInputStream() method of the Delivery object. Calling the rawInputStream() method after calling this method throws ClientIllegalStateException.

        Care should be taken if attempting to specify anything other than the wild card type for the body of the returned message as the wrong type specification can lead to an exception.

        Type Parameters:
        E - The type of message body that should be contained in the returned Message.
        Returns:
        a Message instance that wraps the decoded payload.
        Throws:
        ClientException - if an error occurs while decoding the payload.
