## Member Function Documentation

### void sc::OSSHF::ao\_fock (double accuracy)` [protected]`, ` [virtual]`

Implements **sc::SCF**.

### int sc::OSSHF::gradient\_implemented () const` [virtual]`

Reimplemented from **sc::Function**.

### void sc::OSSHF::print (std::ostream & = ExEnv::out0`()`) const` [virtual]`

Print information about the object.

Reimplemented from **sc::MolecularEnergy**.

### void sc::OSSHF::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**.

### void sc::OSSHF::two\_body\_deriv (double \*)` [protected]`, ` [virtual]`

Implements **sc::SCF**.

### void sc::OSSHF::two\_body\_energy (double & ec, double & ex)` [virtual]`

Reimplemented from **sc::SCF**.

### int sc::OSSHF::value\_implemented () const` [virtual]`

Information about the availability of values, gradients, and hessians.

Reimplemented from **sc::Function**.
