## Public Member Functions

| BeckeIntegrationWeight (const Ref< KeyVal > &)
| BeckeIntegrationWeight (StateIn &)
void | save_data_state (StateOut &)
| Save the base classes (with save_data_state) and the members in the same order that the StateIn CTOR initializes them.
void | init (const Ref< Molecule > &, double tolerance)
| Initialize the integration weight object.
void | done ()
| Called when finished with the integration weight object.
double | w (int center, SCVector3 &point, double *grad_w=0)
| Computes the weight for a given center at a given point in space.

## Detailed Description

Implements Becke's integration weight scheme.

## Member Function Documentation

void sc::BeckeIntegrationWeight::save_data_state | ( | StateOut & |  | ) | `[virtual]`

Save the base classes (with save_data_state) and the members in the same order that the StateIn CTOR initializes them.

This must be implemented by the derived class if the class has data.

Reimplemented from sc::IntegrationWeight.

double sc::BeckeIntegrationWeight::w | ( | int | center,
|  | SCVector3 & | point,
|  | double * | grad_w = `0`
| ) |  | `[virtual]`

Computes the weight for a given center at a given point in space.

Derivatives of the weigth with respect to nuclear coordinates are optionally returned in grad_w. This must be called after init, but before done. It must also be thread-safe.

Implements sc::IntegrationWeight.
