gmx::RangePartitioning Class Reference

#include <gromacs/topology/block.h>

Description

Division of a range of indices into consecutive blocks.

A range of consecutive indices 0 to full.range.end() is divided into numBlocks() consecutive blocks of consecutive indices. Block b contains indices i for which block(b).begin() <= i < block(b).end().

Public Types
using	Block = Range< int >
	A block defined by a range of atom indices.

Public Member Functions
int	numBlocks () const
	Returns the number of blocks.
Block	block (int blockIndex) const
	Returns the size of the block with index blockIndex.
Block	fullRange () const
	Returns the full range.
Block	subRange (int blockIndexBegin, int blockIndexEnd) const
	Returns a range starting at blockIndexBegin and ending at blockIndexEnd.
bool	allBlocksHaveSizeOne () const
	Returns true when all blocks have size 0 or numBlocks()=0.
void	appendBlock (int blockSize)
	Appends a block of size blockSize at the end of the range. More...
void	clear ()
	Removes all blocks.
void	reduceNumBlocks (int newNumBlocks)
	Reduces the number of blocks to newNumBlocks. More...
void	setAllBlocksSizeOne (int numBlocks)
	Sets the partitioning to numBlocks blocks each of size 1.
std::vector< int > &	rawIndex ()
	Returns the raw block index array, avoid using this.

Member Function Documentation

void gmx::RangePartitioning::appendBlock ( int  blockSize )

inline

Appends a block of size blockSize at the end of the range.

Note

blocksize has to be >= 1

void gmx::RangePartitioning::reduceNumBlocks ( int  newNumBlocks )

inline

Reduces the number of blocks to newNumBlocks.

Note

newNumBlocks should be <= numBlocks().
