- \class TQUuid tquuid.h
- \brief The TQUuid class defines a Universally Unique Identifier (UUID).
-
- \reentrant
-
- For objects or declarations that must be uniquely identified,
- UUIDs (also known as GUIDs) are widely used in order to assign a
- fixed and easy to compare value to the object or declaration. The
- 128-bit value of a UUID is generated by an algorithm that
- guarantees that the value is unique.
-
- In TQt, UUIDs are wrapped by the TQUuid struct which provides
- convenience functions for handling UUIDs. Most platforms provide a
- tool to generate new UUIDs, for example, uuidgen and guidgen.
-
- UUIDs generated by TQUuid, are based on the \c Random version of the
- \c DCE (Distributed Computing Environment) standard.
-
- UUIDs can be constructed from numeric values or from strings, or
- using the static createUuid() function. They can be converted to a
- string with toString(). UUIDs have a variant() and a version(),
- and null UUIDs return TRUE from isNull().
