The base class for all of ULAPI's enhanced enumerated types.
ULAPI's enhanced enumerated types are intended to provide an enumerated type where:
- Each enumerated value is an object of the type of the class.
- The class can contain methods (which C++ enums cannot).
- Each enumerated value may be associated with a string for display,
- Each enumerated value may be associated with other data as appropriate. See, for example, the ISO language codes in each instance of the ULLanguage class.
- Looking at an enumerated value in a debugger will show the value's name or meaning in some form, rather than just an integer.
- The type is readily maintained. When you want to change the list of enumerated values, you want to avoid having to change things in a lot of different places. The approach shown here requires changes in one location in the .h file and one location in the .cpp file. No methods need to be modified.
There is one disadvantage to keep in mind. ULAPI enhanced enums cannot be used as cases in switch statements.
