Member Typedef Documentation

template<class BlockMatrixType >

using BlockMatrixIterators::Accessor< BlockMatrixType, false >::size_type = types::global_dof_index

Declare type for container size.

Definition at line 128 of file block_matrix_base.h.

template<class BlockMatrixType >

using BlockMatrixIterators::Accessor< BlockMatrixType, false >::MatrixType = BlockMatrixType

Type of the matrix used in this accessor.

Definition at line 133 of file block_matrix_base.h.

template<class BlockMatrixType >

using BlockMatrixIterators::Accessor< BlockMatrixType, false >::value_type = typename BlockMatrixType::value_type

Typedef the value type of the matrix we point into.

Definition at line 138 of file block_matrix_base.h.

Constructor & Destructor Documentation

template<class BlockMatrixType >

BlockMatrixIterators::Accessor< BlockMatrixType, false >::Accessor	(	BlockMatrixType *	m,
		const size_type	row,
		const size_type	col
	)

Constructor. Since we use accessors only for read access, a const matrix pointer is sufficient.

Place the iterator at the beginning of the given row of the matrix, or create the end pointer if row equals the total number of rows in the matrix.
