class | ::MatrixIterator |
Block matrix accessor for constant matrices, implementing the stepping through a matrix.
Definition at line 207 of file block_matrix_base.h.
using BlockMatrixIterators::Accessor< BlockMatrixType, true >::size_type = types::global_dof_index |
Declare type for container size.
Definition at line 213 of file block_matrix_base.h.
using BlockMatrixIterators::Accessor< BlockMatrixType, true >::MatrixType = const BlockMatrixType |
Type of the matrix used in this accessor.
Definition at line 218 of file block_matrix_base.h.
using BlockMatrixIterators::Accessor< BlockMatrixType, true >::value_type = typename BlockMatrixType::value_type |
Typedef the value type of the matrix we point into.

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.
BlockMatrixIterators::Accessor< BlockMatrixType, true >::Accessor | ( | const Accessor< BlockMatrixType, false > & | ) |
Initialize const accessor from non const accessor.
size_type BlockMatrixIterators::Accessor< BlockMatrixType, true >::row | ( | ) | const |
Row number of the element represented by this object.
size_type BlockMatrixIterators::Accessor< BlockMatrixType, true >::column | ( | ) | const |
Column number of the element represented by this object.
value_type BlockMatrixIterators::Accessor< BlockMatrixType, true >::value | ( | ) | const |
Value of the entry at the current position.
|
protected |
Move ahead one element.
|
protected |
Compare this accessor with another one for equality.
|
inherited |
Block row of the element represented by this object.
|
inherited |
Block column of the element represented by this object.
Definition at line 285 of file block_matrix_base.h.
|
protected |
The matrix accessed.
Definition at line 264 of file block_matrix_base.h.
|
protected |
Iterator of the underlying matrix class.
Definition at line 269 of file block_matrix_base.h.

Block row into which we presently point.

Block column into which we presently point.
