Detailed Description

This implements electron repulsion integrals in the IntCints library.


Member Function Documentation

const double* sc::TwoBodyIntCints::buffer tbint_type  te_type  )  const [inline, virtual]
 

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.

Reimplemented from sc::TwoBodyInt.

int sc::TwoBodyIntCints::log2_shell_bound int  ,
int  ,
int  ,
int 
[virtual]
 

Return log base 2 of the maximum magnitude of any integral in a shell block.

An index of -1 for any argument indicates any shell.

Implements sc::TwoBodyInt.
