%description
This module provides a framework for generating v3 UUIDs (Universally
Unique Identifiers, also known as GUIDs (Globally Unique Identifiers). A
UUID is 128 bits long, and is guaranteed to be different from all other
UUIDs/GUIDs generated until 3400 CE.

UUIDs were originally used in the Network Computing System (NCS) and later
in the Open Software Foundation's (OSF) Distributed Computing Environment.
Currently many different technologies rely on UUIDs to provide unique
identity for various software components. Microsoft COM/DCOM for instance,
uses GUIDs very extensively to uniquely identify classes, applications and
components across network-connected systems.

The algorithm for UUID generation, used by this extension, is described in
the Internet Draft "UUIDs and GUIDs" by Paul J. Leach and Rich Salz. (See
RFC 4122.) It provides reasonably efficient and reliable framework for
generating UUIDs and supports fairly high allocation rates -- 10 million
per second per machine -- and therefore is suitable for identifying both
extremely short-lived and very persistent objects on a given system as well
as across the network.

This modules provides several methods to create a UUID. In all methods,
'<namespace>' is a UUID and '<name>' is a free form string.

   # creates binary (16 byte long binary value) UUID.
   $ug->create();
   $ug->create_bin();

   # creates binary (16-byte long binary value) UUID based on particular
   # namespace and name string.
   $ug->create_from_name(<namespace>, <name>);
   $ug->create_from_name_bin(<namespace>, <name>);

   # creates UUID string, using conventional UUID string format,
   # such as: 4162F712-1DD2-11B2-B17E-C09EFE1DC403
   # Note that digits A-F are capitalized, which is contrary to rfc4122
   $ug->create_str();
   $ug->create_from_name_str(<namespace>, <name>);

   # creates UUID string as a hex string,
   # such as: 0x4162F7121DD211B2B17EC09EFE1DC403
   # Note that digits A-F are capitalized, which is contrary to rfc4122
   $ug->create_hex();
   $ug->create_from_name_hex(<namespace>, <name>);

   # creates UUID string as a Base64-encoded string
   $ug->create_b64();
   $ug->create_from_name_b64(<namespace>, <name>);

   Binary UUIDs can be converted to printable strings using following methods:

   # convert to conventional string representation
   $ug->to_string(<uuid>);

   # convert to hex string (using upper, rather than lower, case letters)
   $ug->to_hexstring(<uuid>);

   # convert to Base64-encoded string
   $ug->to_b64string(<uuid>);

   Conversly, string UUIDs can be converted back to binary form:

   # recreate binary UUID from string
   $ug->from_string(<uuid>);
   $ug->from_hexstring(<uuid>);

   # recreate binary UUID from Base64-encoded string
   $ug->from_b64string(<uuid>);

   Finally, two binary UUIDs can be compared using the following method:

   # returns -1, 0 or 1 depending on whether uuid1 less
   # than, equals to, or greater than uuid2
   $ug->compare(<uuid1>, <uuid2>);

Examples:

   use Data::UUID;

   # this creates a new UUID in string form, based on the standard namespace
   # UUID NameSpace_URL and name "www.mycompany.com"

   $ug = Data::UUID->new;
   print $ug->create_from_name_str(NameSpace_URL, "www.mycompany.com");
