public class UtilPublisher
extends DefaultContextPublisher

Class that can be used to easily create a Context Publisher that can be used in almost all situations. This simple Publisher extends the DefaultContextPublisher included in the MW, 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.

Example: A publisher that gives events about status of a Heater Actuator.

publisher = new UtilPublisher(context, DEVICE_INSTANCE_URI,

ContextProviderType.controller,

new HeaterActuator(DEVICE_INSTANCE_URI),

HeaterActuator.PROP_STATUS,

TypeMapper.getDatatypeURI(Boolean.class));
