All Implemented Interfaces:

org.osgi.service.device.Constants, org.osgi.util.tracker.ServiceTrackerCustomizer, IKnxDpt9, IKnxReceiveMessage

public class KnxDpt9Instance
extends KnxDriver
implements IKnxDpt9, IKnxReceiveMessage, org.osgi.util.tracker.ServiceTrackerCustomizer, org.osgi.service.device.Constants

Working instance of the IKnxDpt9 driver. Registers a service/device in OSGi registry. Tracks on the KNX groupDevice service passed in the attach method in KnxDpt9Driver 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 from the groupDevice. This driver handles knx float values (2 byte) i.e. for temperature (knx datapoint type 9).
