Examples of org.apache.hedwig.client.data.MessageConsumeData

org.apache.hedwig.client.data.MessageConsumeData
Wrapper class to store all of the data points needed to encapsulate Message Consumption in the Subscribe flow for consuming a message sent from the server for a given TopicSubscriber. This will be used as the Context in the VoidCallback for the MessageHandlers once they've completed consuming the message.

            .asyncMessageConsume(messageConsumeData.msg);
        }
    }


    public void operationFinished(Object ctx, Void resultOfOperation) {
        MessageConsumeData messageConsumeData = (MessageConsumeData) ctx;
        TopicSubscriber topicSubscriber = new TopicSubscriber(messageConsumeData.topic, messageConsumeData.subscriberId);
        // Message has been successfully consumed by the client app so callback
        // to the ResponseHandler indicating that the message is consumed.
        Channel topicSubscriberChannel = client.getSubscriber().getChannelForTopic(topicSubscriber);
        HedwigClientImpl.getResponseHandlerFromChannel(topicSubscriberChannel).getSubscribeResponseHandler()
