Member Function Documentation
- void sc::PW91XFunctional::save_data_state (StateOut &) [virtual]
- Save the base classes (with save_data_state) and the members in the
same order that the StateIn CTOR initializes them. - This must be implemented by the derived class if the class has data.
- Reimplemented from sc::DenFunctional.
