Detailed Description

Block Connectivity table.

Author: Willem Deconinck Container for connectivity tables that are layed out in memory as a block. Every row has the same number of columns.

There are 2 modes of construction:

It wraps existing raw data
It owns the connectivity data

In case ATLAS_HAVE_FORTRAN is defined (which is usually the case), the raw data will be stored with base 1 for Fortran interoperability. The operator(row,col) will then do the conversion to base 0.

In the first mode of construction, the connectivity table cannot be resized. In the second mode of construction, resizing is possible

Constructor & Destructor Documentation

◆ BlockConnectivityImpl()

atlas::mesh::BlockConnectivityImpl::BlockConnectivityImpl	(	idx_t	rows,
		idx_t	cols,
		idx_t	values[]
	)

Construct connectivity table wrapping existing raw data.

No resizing can be performed as data is not owned.

Member Function Documentation

◆ add()

void atlas::mesh::BlockConnectivityImpl::add	(	idx_t	rows,
		idx_t	cols,
		const idx_t	values[],
		bool	fortran_array = `false`
	)

Resize connectivity, and add given rows.

Note: Can only be used when data is owned.

◆ data()

ATLAS_HOST_DEVICE const idx_t* atlas::mesh::BlockConnectivityImpl::data ( ) const

inline

Access to raw data.

Note that the connectivity base is 1 in case ATLAS_HAVE_FORTRAN is defined.

◆ operator()()

idx_t atlas::mesh::BlockConnectivityImpl::operator()	(	idx_t	row_idx,
		idx_t	col_idx
	)		const

inline

Access to connectivity table elements for given row and column The returned index has base 0 regardless if ATLAS_HAVE_FORTRAN is defined.
