LocalDevice

public class LocalDevice extends Object
This class is defined by the JSR-82 specification Java™ APIs for Bluetooth™ Wireless Technology, Version 1.1.

Fields Summary
private static LocalDevice
localDevice
Keeps this singleton object.
private static com.sun.kvem.jsr082.bluetooth.LocalDeviceImpl
localDeviceImpl
Keeps the reference to implementation object.
private DiscoveryAgent
discoveryAgent
Keeps the discovery agen reference - because the DiscoveryAgent. is package private, so it can't be created ffrom the implemetation.
Constructors Summary
private LocalDevice()
The default constructor is hidden so that no one can create a new instance of the LocalDevice. To get the LocalDevice object for this device, use the getLocalDevice() static method in this class.

#getLocalDevice
