Models

Mqtt

Extra models to make it easier to work with the Eclipse Paho lib.

Subscribing

Using MqttSubscriber:

with(subscriber) { // context remembers subscriber info
    client.subscribe { (topic: String, mqttMessage: MqttMessage) -> 
        // do stuff
    }
}

Publishing

Using MqttPublisher:

with(publisher) { // context remembers publisher info
    client.publish("publish anything")
}

Topics

Topics are built dynamically for components by the MqttTopicBuilder class

Traffic

Traffic models such as lights and barriers can be found in the model.traffic package.

Core components (read: base classes and interfaces) can be found in the nested core package.

Everything is based around the ITrafficControl interface
