Detailed Description

       An abstract base class from which the various VWN (Vosko, Wilk and Nusair) local
       correlation functional (1, 2, 3, 4, 5) classes are derived.

Member Function Documentation

   void sc::VWNLCFunctional::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::LSDACFunctional.

       Reimplemented in sc::VWN5LCFunctional, sc::VWN4LCFunctional, sc::VWN3LCFunctional,
       sc::VWN2LCFunctional, and sc::VWN1LCFunctional.
