Member Function Documentation

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.
