Member Function Documentation

◆ compute()

void sc::SumMolecularEnergy::compute ( )
protectedvirtual

Recompute at least the results that have compute true and are not already computed.

This should only be called by Result's members.

Implements sc::Compute.

Reimplemented in sc::MP2BasisExtrap.

◆ save_data_state()

void sc::SumMolecularEnergy::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::MolecularEnergy.

Reimplemented in sc::MP2BasisExtrap.
