    Data Structures

    class  TDF_DerivedAttribute
     Class provides global access (through static methods) to all derived attributes information. It is used internally by macros for registration of derived attributes and driver-tables for getting this data. More...

    Macros

     Defines declaration of Handle method and declares methods for serialization of derived attribute.
    #define IMPLEMENT_DERIVED_ATTRIBUTE(Class, Base)
     Defines implementation of Handle method, serialization methods and registers the derived attribute.
    #define IMPLEMENT_DERIVED_ATTRIBUTE_WITH_TYPE(Class, Base, NameSpace, TypeName)
     Defines implementation of Handle method and registers the derived attribute.
