Member Function Documentation

void sc::MP2R12Energy::print (std::ostream & = ExEnv::out0()) const [virtual]

Print the object.

Reimplemented from sc::DescribedClass.

void sc::MP2R12Energy::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::SavableState.
