sc::TwoBodyTwoCenterDerivInt(3)	     MPQC      sc::TwoBodyTwoCenterDerivInt(3)

NAME
       sc::TwoBodyTwoCenterDerivInt - This is an abstract base type for
       classes that compute two	centers	integrals involving two	electrons.

SYNOPSIS
       #include	<tbint.h>

       Inherits	sc::RefCount.

   Public Member Functions
       int nbasis () const
	   Return the number of	basis functions	on center one.
       int nbasis1 () const
	   Return the number of	basis functions	on center one.
       int nbasis2 () const
	   Return the number of	basis functions	on center two.
       int nshell () const
	   Return the number of	shells on center one.
       int nshell1 () const
	   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 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.
