class | ::MatrixIterator |
Block matrix accessor for constant matrices, implementing the stepping through a matrix.
Definition at line 225 of file block_matrix_base.h.
typedef types::global_dof_index BlockMatrixIterators::Accessor< BlockMatrix, true >::size_type |
Declare type for container size.
Definition at line 233 of file block_matrix_base.h.
typedef const BlockMatrix BlockMatrixIterators::Accessor< BlockMatrix, true >::MatrixType |
Type of the matrix used in this accessor.
Definition at line 239 of file block_matrix_base.h.
typedef BlockMatrix::value_type BlockMatrixIterators::Accessor< BlockMatrix, true >::value_type |
Typedef the value type of the matrix we point into.

BlockMatrixIterators::Accessor< BlockMatrix, true >::Accessor | ( | const BlockMatrix * | 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.
BlockMatrixIterators::Accessor< BlockMatrix, true >::Accessor | ( | const Accessor< BlockMatrix, false > & | ) |
Initalize const accessor from non const accessor.
size_type BlockMatrixIterators::Accessor< BlockMatrix, true >::row | ( | ) | const |
Row number of the element represented by this object.
size_type BlockMatrixIterators::Accessor< BlockMatrix, true >::column | ( | ) | const |
Column number of the element represented by this object.
value_type BlockMatrixIterators::Accessor< BlockMatrix, 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.
Let the iterator class be a friend.
Definition at line 316 of file block_matrix_base.h.
|
protected |
The matrix accessed.
Definition at line 292 of file block_matrix_base.h.
|

Iterator of the underlying matrix class.
