Examples of com.rabbitmq.client.GetResponse

com.rabbitmq.client.GetResponse
Encapsulates the response from a {@link Channel#basicGet} message-retrieval method call- essentially a static bean "holder" with message response data.


        for (int i = 0; i < N; i++) {
            basicPublishVolatile(X, K);
        }


        GetResponse response = channel.basicGet(Q, true);
        assertNull("The initial response SHOULD BE null", response);


        deleteQueue(Q);
        deleteExchange(X);
    }
