public abstract class UtilSubscriber
extends ContextSubscriber

This abstract class can be extended to create a simple Context Subscriber. This simple Subscriber extends the normal ContextSubscriber, but allows specifying everything it needs in its constructor. Also because of this it can be used as well with the native API to apply further restrictions and configuration over it. Your class that extends this will receive the specified events in the handleContextEvent method.

Example: A subscriber that listens for events of status of Heater Actuators.

subscriber = new SubscriberExample(context, HeaterActuator.MY_URI,

HeaterActuator.PROP_STATUS, null);
