## Member Function Documentation

### void sc::R12IntEval\_sbs\_A::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**.
