## Member Function Documentation

### void sc::TwoBodyMOIntsTransform\_ikjy::check\_int\_symm (double threshold = TwoBodyMOIntsTransform::zero\_integral) const` [virtual]`, ` [noexcept]`

Check symmetry of transformed integrals.

Implements **sc::TwoBodyMOIntsTransform**.

### void sc::TwoBodyMOIntsTransform\_ikjy::compute ()` [virtual]`

Computes transformed integrals.

Implements **sc::TwoBodyMOIntsTransform**.

### const size\_t sc::TwoBodyMOIntsTransform\_ikjy::memgrp\_blksize () const` [virtual]`

Returns the number of bytes allocated for each ij-block of integrals of one type in **MemoryGrp**.

Implements **sc::TwoBodyMOIntsTransform**.

### void sc::TwoBodyMOIntsTransform\_ikjy::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::SavableState**.

### std::string sc::TwoBodyMOIntsTransform\_ikjy::type () const` [inline]`, ` [virtual]`

Implementation of **TwoBodyMOIntsTransform::type()**

Implements **sc::TwoBodyMOIntsTransform**.
