Examples of MQTTSubscription

org.apache.activemq.transport.mqtt.MQTTSubscription
Keeps track of the MQTT client subscription so that acking is correctly done.

Examples of org.apache.activemq.transport.mqtt.MQTTSubscription

    public byte onSubscribe(final Topic topic) throws MQTTProtocolException {


        final String destinationName = topic.name().toString();
        final QoS requestedQoS = topic.qos();


        final MQTTSubscription mqttSubscription = mqttSubscriptionByTopic.get(destinationName);
        if (mqttSubscription != null) {
            if (requestedQoS != mqttSubscription.getQoS()) {
                // remove old subscription as the QoS has changed
                onUnSubscribe(destinationName);
            } else {
                try {
                    onReSubscribe(mqttSubscription);
