Description
This class implements a generator for Universal Unique Identifiers, as specified in Appendix A of the DCE 1.1 Remote Procedure Call Specification (http://www.opengroup.org/onlinepubs/9629399/), RFC 2518 (WebDAV), section 6.4.1 and the UUIDs and GUIDs internet draft by Leach/Salz from February, 1998 (http://ftp.ics.uci.edu/pub/ietf/webdav/uuid-guid/draft-leach-uuids-guids-01.txt)
Member Summary
Member Functions: create, createFromName, createOne, createRandom, defaultGenerator, getNode, timeStamp
Constructors
UUIDGenerator
Creates the UUIDGenerator.
Destructor
~UUIDGenerator
~UUIDGenerator();
Destroys the UUIDGenerator.
Member Functions
create
UUID create();
Creates a new time-based UUID, using the MAC address of one of the system's ethernet adapters.
Throws a SystemException if no MAC address can be obtained.
createFromName
UUID createFromName(
const UUID & nsid,
const std::string & name
);
Creates a name-based UUID.
createFromName
UUID createFromName(
const UUID & nsid,
const std::string & name,
DigestEngine & de
);
Creates a name-based UUID, using the given digest engine.
createOne
UUID createOne();
Tries to create and return a time-based UUID (see create()), and, if that does not work due to the unavailability of a MAC address, creates and returns a random UUID (see createRandom()).
The UUID::version() method can be used to determine the actual kind of the UUID generated.
createRandom
UUID createRandom();
Creates a random UUID.
defaultGenerator 
static UUIDGenerator & defaultGenerator();
Returns a reference to the default UUIDGenerator.
getNode 
void getNode();
timeStamp
Timestamp::UtcTimeVal timeStamp();
