## Detailed Description

IntegralCCA provides an SC client for CCA IntegralEvaluator components.

## Constructor & Destructor Documentation

sc::IntegralCCA::IntegralCCA | ( | IntegralEvaluatorFactory | eval_factory,
|  | bool | use_opaque,
|  | const Ref< GaussianBasisSet > & | b1 = `0`,
|  | const Ref< GaussianBasisSet > & | b2 = `0`,
|  | const Ref< GaussianBasisSet > & | b3 = `0`,
|  | const Ref< GaussianBasisSet > & | b4 = `0` |
| ) |  |  |

This constructor is used when the framework is not embedded.

sc::IntegralCCA::IntegralCCA | ( | const Ref< KeyVal > & |  | ) |

The KeyVal constructor.

This constructor is used when the framework is embedded. The following keywords are read:

`evaluator_factory`

  This gives the symbol name of a CCA IntegralEvaluatorFactory component. This symbol name should also appear in the cca-load argument. The default is `MPQC.IntegralEvaluatorFactory`.

`integral_package`

  If the default `MPQC.IntegralEvaluatorFactory` is used, then this option may be used to specify the integrals package to use (`intv3` or `cints`). The default is `intv3`.

`molecule`
  This gives a molecule object, it is required.
