           Return the number of shells on center one.
       int nshell2 () const
           Return the number of shells on center two.
       Ref< GaussianBasisSet > basis ()
           Return the basis set on center one.
       Ref< GaussianBasisSet > basis1 ()
           Return the basis set on center one.
       Ref< GaussianBasisSet > basis2 ()
           Return the basis set on center two.
       const double * buffer () const
           The computed shell integrals will be put in the buffer returned by
           this member.
       virtual void compute_shell (int, int, DerivCenters &)=0
           Given for shell indices, this will cause the integral buffer to be
           filled in.
       virtual int log2_shell_bound (int=-1, int=-1)=0
           Return log base 2 of the maximum magnitude of any integral in a
           shell block.

       integrals involving two electrons.

Member Function Documentation
   virtual void sc::TwoBodyTwoCenterDerivInt::compute_shell (int, int,
       DerivCenters &) [pure virtual]
       Given for shell indices, this will cause the integral buffer to be
       filled in.

   virtual int sc::TwoBodyTwoCenterDerivInt::log2_shell_bound (int = -1, int =
       -1) [pure virtual]
       Return log base 2 of the maximum magnitude of any integral in a shell
       block. An index of -1 for any argument indicates any shell.
