• Examples:

*In the case that a single UUID needs to be created or converted the aliases which are defined in the class
*cl_system_uuid can be used.

*To create more than one UUID, the class cl_uuid_factory can be used to create an object of the type
*cl_system_uuid which implements if_system_uuid. This object then can be used for both UUID creation and
*UUID conversion.
