Member Function Documentation

void sc::PW92LCFunctional::point_lc (const PointInputData &, PointOutputData &, double &, double &, double &) [virtual]

Implements sc::LSDACFunctional.

void sc::PW92LCFunctional::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.
