## Detailed Description

OneBodyInt is an abstract base class for objects that compute integrals between two basis functions.

## Member Function Documentation

virtual Ref<OneBodyInt> sc::OneBodyInt::clone | ( |  | ) | `[virtual]`

Returns a clone of this.

The default implementation throws an exception.

Reimplemented in sc::OneBodyIntCints, sc::OneBodyIntCCA, and sc::OneBodyIntV3.

virtual bool sc::OneBodyInt::cloneable | ( |  | ) | `[virtual]`

Return true if the clone member can be called.

The default implementation returns false.

Reimplemented in sc::OneBodyIntCints, sc::OneBodyIntCCA, and sc::OneBodyIntV3.

virtual void sc::OneBodyInt::compute_shell | ( | int | ,
|  | int |  |
| ) |  |  | `[pure virtual]`

Computes the integrals between basis functions in the given shell pair.

Implemented in sc::OneBodyIntCints, sc::OneBodyIntCCA, sc::OneBodyIntV3, sc::PointChargeIntV3, sc::EfieldDotVectorIntV3, and sc::DipoleIntV3.

virtual void sc::OneBodyInt::reinitialize | ( |  | ) | `[virtual]`

This is called for one body integrals that take data to let them know that the data they reference has changed.
