void sc::DFPUpdate::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::HessianUpdate. Reimplemented in sc::BFGSUpdate.
