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.
