Class KnxDpt5Instance

java.lang.Object
  org.universAAL.lddi.knx.interfaces.KnxDriver
      org.universAAL.lddi.knx.driver.KnxDpt5Instance

All Implemented Interfaces:

org.osgi.service.device.Constants, org.osgi.util.tracker.ServiceTrackerCustomizer, IKnxDpt5, IKnxReceiveMessage

public class KnxDpt5Instance
extends KnxDriver
implements IKnxDpt5, IKnxReceiveMessage, org.osgi.util.tracker.ServiceTrackerCustomizer, org.osgi.service.device.Constants

Working instance of the IKnxDpt5 driver. Registers a service/device in OSGi registry. Tracks on the KNX groupDevice service passed in the attach method in KnxDpt5Driver class. This instance is passed to the consuming client (e.g. uAAL exporter bundle). When the KNX groupDevice service disappears, this driver is removed from the consuming client and detached from the groupDevice. This driver handles knx 4-bit unsigned int events (knx datapoint 5), which is dimming step and blind step.
