virtual void save_vbase_state(StateOut &)
Save the virtual bases for the object.
SavableState(StateIn &)
Each derived class StateIn CTOR handles the restore corresponding to calling save_object_state,...

This can be used for saving state when the exact type of the object is known for both the save and th...
static SavableState * key_restore_state(StateIn &si, const char *keyword)
Like restore_state, but keyword is used to override values while restoring.
static SavableState * restore_state(StateIn &si)
Restores objects saved with save_state.
virtual void save_data_state(StateOut &)
Save the base classes (with save_data_state) and the members in the same order that the StateIn CTOR ...
void save_state(StateOut &)
Save the state of the object as specified by the StateOut object.
