| jL (const Grid &r_grid, const Grid &q_grid, std::size_t max_l, bool subtract_one=false) | |
| Contruction takes radial grid, a q grid, and a maximum L. Fills lookup table. | |
| jL (const jL &other) | |
| Constructing from existing operator: copies JL table - faster. Can copy from a jL of different type (g0,g5 etc) | |
| jL & | operator= (const jL &)=delete |
| std::size_t | L () const |
| Current value of L (should = rank) | |

| virtual double | radialIntegral (const DiracSpinor &Fa, const DiracSpinor &Fb) const override final |
| Defined via <a||h||b> = angularF(a,b) * radialIntegral(a,b) (Note: if radial_rhs is overridden, then radialIntegral must also be_. | |
| double | rme (const DiracSpinor &a, const DiracSpinor &b, std::size_t L, double q) const |
| Directly calculate reduced matrix element without needing to call set_L_q - this is thread safe. | |
