const double * buffer () const
The computed shell integrals will be put in the buffer returned by this member.
virtual void compute_shell (int, int, 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, int=-1, int=-1)=0
Return log base 2 of the maximum magnitude of any integral in a shell block.
