public class UDN
- extends Object
A unique device name.
UDA 1.0 does not specify a UUID format, however, UDA 1.1 specifies a format that is compatible
with java.util.UUID variant 4. You can use any identifier string you like.
You'll most likely need the uniqueSystemIdentifier(String)
method sooner or later.

uniqueSystemIdentifier
public static UDN uniqueSystemIdentifier(String salt)
- Generates a global unique identifer that is the same every time this method is invoked on the same machine.
This method discovers various pieces of information about the local system such
as hostname, MAC address, OS name and version. It then combines this information with the
given salt to generate a globally unique identifer. In other words, every time you
call this method with the same salt on the same machine, you get the same identifer.
If you use the same salt on a different machine, a different identifier will be generated.
Control points can remember your device's identifer, it will be the same every time
your device is powered up.
- Parameters:
salt
- An arbitrary string that uniquely identifies the devices on the current system, e.g. "MyMediaServer".
- Returns:
- A global unique identifier, stable for the current system and salt.
