Member Function Documentation
◆ save_data_state()
|
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::DenFunctional.
The documentation for this class was generated from the following file:
