Detailed Description

       This is a base class for a container for a sparse Cartesian to solid harmonic basis
       function transformation.

Constructor & Destructor Documentation

   sc::SphericalTransform::SphericalTransform (int l, int subl = -1) [protected]
       This constructs the SphericalTransform for the given Cartesian angular momentum l and
       solid harmonic angular momentum subl. Usually, l and subl will be the same. They would
       differ when the S component of a D Cartesian shell or the P component of an F Cartesian
       shell is desired, for example (see the natural atomic orbital code for an example of such
       use). The init member must be called to complete initialization.

Member Function Documentation

   virtual void sc::SphericalTransform::init () [protected],  [virtual]
       This determines all of the components of the transformation. It should be possible to
       implement the SphericalTransformComponent::init specialization in such a way that the
       default SphericalTransform::init can be used.

       Reimplemented in sc::ISphericalTransform.
