template<typename Tile, typename Policy>
class mpqc::lcao::DirectFockBuilder< Tile, Policy >

DirectFockBuilder is an integral-direct implementation of FockBuilder in a Gaussian AO basis that uses 4-center integrals and optimally takes advantage of the permutational symmetry and shell-level screening.

inlineoverridevirtual

computes the J+K part of the Fock matrix with variable fraction of J and K

Parameters

D	the (1-particle) density matrix
C	the occupied orbital AO coefficient matrix
scale_J_by	the coefficient of J in the result
scale_K_by	the coefficient of K in the result
target_precision	the (absolute) target precision of the Fock matrix; this precision is not in general guaranteed, but the actual precision of the Fock matrix is usually proportional to this value.

Returns: the J+K contribution to the Fock matrix an optional energy correction
