◆ save_data_state()

void sc::TwoBodyMOIntsTransform_ijxy::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.
