Member Function Documentation

associate()

void Alien::DoKLocalMatrixIndexer::associate ( Integer i, Integer j, Offset offset )

overridevirtual

Registers an offset with a matrix position (i,j)

Parameters

i	id of the row
j	id of the column
offset

Implements Alien::ILocalMatrixIndexer.

Definition at line 38 of file DoKLocalMatrixIndexer.cc.

clone()

ILocalMatrixIndexer * Alien::DoKLocalMatrixIndexer::clone ( ) const

overridevirtual

Implements Alien::ILocalMatrixIndexer.

Definition at line 67 of file DoKLocalMatrixIndexer.cc.

create()

DoKLocalMatrixIndexer::Offset Alien::DoKLocalMatrixIndexer::create ( Integer i, Integer j, Offset & tentative_offset )

overridevirtual

Creates a new offset for matrix position (i,j)

Parameters

i
j
tentative_offset	hint on what the offset should be

Returns

the offset (can be different from tentative_offset)

Implements Alien::ILocalMatrixIndexer.

Definition at line 55 of file DoKLocalMatrixIndexer.cc.

find()

std::optional< ILocalMatrixIndexer::Offset > Alien::DoKLocalMatrixIndexer::find ( Integer i, Integer j )

overridevirtual

Finds the offset associated with a matrix position (i,j)

Parameters

i
j

Returns

offset if found

Implements Alien::ILocalMatrixIndexer.

Definition at line 44 of file DoKLocalMatrixIndexer.cc.

sort()

IReverseIndexer * Alien::DoKLocalMatrixIndexer::sort ( Arccore::Array< Renumbering > & perm )

overridevirtual

Creates a new indexer, based on offset permutations.

Parameters

perm	permutation array, to be filled by this function.

Returns

new indexer, used to compact matrix

Implements Alien::ILocalMatrixIndexer.
