| ENTITY is the common class for all data structure entity definitions. It defines the base class for all permanent model types. | |||||
| Macros are provided in the ENTITY class header file (entity.hxx) for simplifying the definition of user entities as classes derived from ENTITY. There are many class methods required for any entity. Many of them are the same for all entities, and many of the others have elements in common. The macros help with this commonality. Refer to Chapter 9, Entity Derivation Macros, for descriptions of these macros and how to use them. | |||||
