Detailed Description

       This implements electron repulsion integrals in the IntCints library.

Member Function Documentation

   const double* sc::TwoBodyIntCints::buffer (tbint_type type) const [inline],  [virtual]
       The computed shell integrals will be put in the buffer returned by this member. Some
       TwoBodyInt specializations have more than one buffer: The type arguments selects which
       buffer is returned. If the requested type is not supported, then 0 is returned.

       Reimplemented from sc::TwoBodyInt.

   void sc::TwoBodyIntCints::compute_shell (int, int, int, int) [virtual]
       Given four shell indices, integrals will be computed and placed in the buffer. The first
       two indices correspond to electron 1 and the second two indices correspond to electron 2.

       Implements sc::TwoBodyInt.

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

       Implements sc::TwoBodyInt.
