void sc::TwoBodyDerivIntCints::compute_shell (int, int, int, int, DerivCenters &) [virtual]

Given for shell indices, this will cause the integral buffer to be filled in.

Implements sc::TwoBodyDerivInt.

int sc::TwoBodyDerivIntCints::log2_shell_bound (int, int, int, int) [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.
