Detailed Description
template<int NumCenters>
class sc::TwoBodyIntBatchGeneric< NumCenters >
This is a generic implementation of TwoBodyIntBatch in terms of a TwoBodyInt.
Member Function Documentation
◆ buffer()
|
inlinevirtual |
The computed shell integrals will be put in the buffer returned by this member.
Some TwoBodyInt specializations have more than one buffer: The type arguments selects which buffer is returned. If the requested type is not supported, then 0 is returned. TODO JTF implement
Implements sc::TwoBodyIntBatch< NumCenters >.
◆ clone()
|
inlinevirtual |
Returns a clone of this.
The default implementation throws an exception. TODO JTF implement
Implements sc::TwoBodyIntBatch< NumCenters >.
References sc::TwoBodyIntEval::clone().
◆ cloneable()
|
inlinevirtual |
Return true if the clone member can be called.
The default implementation returns false. TODO JTF implement
Implements sc::TwoBodyIntBatch< NumCenters >.
◆ set_integral_storage()
|
inlinevirtual |
This storage is used to cache computed integrals.
TODO: do we really want to allocate by size_t, instead of number of elements?
Implements sc::TwoBodyIntBatch< NumCenters >.
◆ type()
|
inlinevirtual |
Returns the type of the operator set that this object computes.
this function is necessary to describe the computed integrals (their number, symmetries, etc.) and/or to implement cloning.
Implements sc::TwoBodyIntBatch< NumCenters >.
