Method Summary

Modifier and Type	Method and Description
UUID	getUuid() This method gets the UUID of this object.

Method Detail

getUuid

UUID getUuid()

This method gets the UUID of this object. When the object is created, a UUID is generated. In case the object is created from another object that already has a UUID, the existing UUID will be used (e.g. for chained exceptions).
The UUID will appear in a stacktrace but NOT in the message. It will therefore be written to log-files if the NlsThrowable is logged. If you supply the UUID to the end-user in an error panel or popup (see Message), he can provide it with the problem report so an administrator or software developer can easily find the stacktrace in the log-files.

Returns:

the UUID of this object. It may be null if this feature is NOT supported by the type of this object or turned of (it is turned on by default).
