# sc\_R12IntsAcc\_MPIIOFile\_Ind(3)

## NAME

sc::R12IntsAcc\_MPIIOFile\_Ind

## SYNOPSIS

Inherits **sc::R12IntsAcc\_MPIIOFile**.

### Public Member Functions

**R12IntsAcc\_MPIIOFile\_Ind** (**Ref**\< **MemoryGrp** \> &mem, const char \*filename, int **num\_te\_types**, int **ni**, int **nj**, int **nx**, int **ny**)\
 **R12IntsAcc\_MPIIOFile\_Ind** (**StateIn** &)\
 void **save\_data\_state** (**StateOut** &)\
 Save the base classes (with save\_data\_state) and the members in the same order that the **StateIn** CTOR initializes them.  void **store\_memorygrp** (**Ref**\< **MemoryGrp** \> &mem, int **ni**, const size\_t blksize=0)\
 Stores all pair block of integrals held in mem.  double \* **retrieve\_pair\_block** (int i, int j, **tbint\_type** oper\_type)\
 Retrieves an ij pair block of integrals from the file.

### Additional Inherited Members

## Member Function Documentation

### double \* sc::R12IntsAcc\_MPIIOFile\_Ind::retrieve\_pair\_block (int i, int j, tbint\_type oper\_type)` [virtual]`

Retrieves an ij pair block of integrals from the file.

Implements **sc::R12IntsAcc**.

### void sc::R12IntsAcc\_MPIIOFile\_Ind::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::R12IntsAcc\_MPIIOFile**.

### void sc::R12IntsAcc\_MPIIOFile\_Ind::store\_memorygrp (Ref\< MemoryGrp \> & mem, int ni, const size\_t blksize = `0`)` [virtual]`

Stores all pair block of integrals held in mem. By default blocks are appended to the end of the same file, i.e. they are assumed to have come from consecutive passes of the same transformation. This is a collective operation. See documentation for **R12IntsAcc::store\_memorygrp()** for more info.

Implements **sc::R12IntsAcc**.
