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.
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.
using BlockMatrixIterators::Accessor< BlockMatrixType, false >::value_type = typename BlockMatrixType::value_type |
Typedef the value type of the matrix we point into.

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.
size_type BlockMatrixIterators::Accessor< BlockMatrixType, false >::row | ( | ) | const |
Row number of the element represented by this object.
size_type BlockMatrixIterators::Accessor< BlockMatrixType, false >::column | ( | ) | const |
Column number of the element represented by this object.
value_type BlockMatrixIterators::Accessor< BlockMatrixType, false >::value | ( | ) | const |
Value of the entry at the current position.
void BlockMatrixIterators::Accessor< BlockMatrixType, false >::set_value | ( | value_type | newval | ) | const |
Set new value.

Move ahead one element.

Compare this accessor with another one for equality.

The matrix accessed.
Definition at line 178 of file block_matrix_base.h.

Iterator of the underlying matrix class.
