Member Function Documentation
Ref<OneBodyInt> sc::IntegralCints::dipole (const Ref< DipoleData > & = 0)
[virtual]
Return a OneBodyInt that computes electric dipole moment integrals. The
canonical order of integrals in a set is x, y, z.
Implements sc::Integral.
Ref<OneBodyInt> sc::IntegralCints::efield_dot_vector (const Ref<
EfieldDotVectorData > & = 0) [virtual]
Return a OneBodyInt that computes the electric field integrals dotted
with a given vector.
Implements sc::Integral.
Ref<TwoBodyInt> sc::IntegralCints::grt () [virtual]
Return a TwoBodyInt that computes two-electron integrals specific to
linear R12 methods. According to the convention in the literature, ’g’
stands for electron repulsion integral, ’r’ for the integral of r12
operator, and ’t’ for the commutator integrals. Implementation for this
kind of TwoBodyInt is optional.
Reimplemented from sc::Integral.
CartesianIter* sc::IntegralCints::new_cartesian_iter (int) [virtual]
Return a CartesianIter object. The caller is responsible for freeing
the object.
Implements sc::Integral.

(int) [virtual]
Return a RedundantCartesianIter object. The caller is responsible for
freeing the object.
Implements sc::Integral.

Implements sc::Integral.
Ref<OneBodyInt> sc::IntegralCints::nuclear () [virtual]
Return a OneBodyInt that computes the nuclear repulsion integrals.
Charges from the atoms on center one are used. If center two is not

Return a OneBodyInt that computes the integrals for interactions with
point charges.

The canonical order of integrals in a set is x^2, xy, xz, y^2, yz, z^2.
Implements sc::Integral.
void sc::IntegralCints::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::Integral.
