   Public Member Functions
       CLKS (StateIn &)
       CLKS (const Ref< KeyVal > &)
           This KeyVal constructor reads the following keywords:
       void save_data_state (StateOut &)
           Save the base classes (with save_data_state) and the members in the same order that
           the StateIn CTOR initializes them.
       void print (std::ostream &o=ExEnv::out0()) const
           Print information about the object.
       void two_body_energy (double &ec, double &ex)
       int value_implemented () const
           Information about the availability of values, gradients, and hessians.
       int gradient_implemented () const
       RefSymmSCMatrix density ()
           Returns the SO density.

Detailed Description

Constructor & Destructor Documentation

   sc::CLKS::CLKS (const Ref< KeyVal > &)
       This KeyVal constructor reads the following keywords:

       integrator
           Specifies the DenIntegrator that will be used to integrate the density functional. The
           default is RadialAngularIntegrator.

       functional
           Specifies the DenFunctional that will be used to compute the exchange/correlation
           contribution. This is no default.

Member Function Documentation

   void sc::CLKS::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.
