class | MatrixIterator |
Iterator for constant and non-constant matrices.
This iterator is abstracted from the actual matrix type and can be used for any matrix having the required AccessorType type.
Definition at line 32 of file matrix_iterator.h.
using MatrixIterator< AccessorType >::size_type = types::global_dof_index |
Declare type for container size.
Definition at line 38 of file matrix_iterator.h.
using MatrixIterator< AccessorType >::MatrixType = typename AccessorType::MatrixType |
Typedef for the matrix type (including constness) we are to operate on.

Constructor. Create an iterator into the matrix matrix
for the given row
and the index
within it.

Copy from another matrix iterator. Mostly implemented to allow initialization of a constant iterator from a non constant, this function only requires that a conversion from the other iterator's AccessorType to this AccessorType object is possible.

Comparison. True, if both accessors are equal.

Comparison operator. Result is true if either the first row number is smaller or if the row numbers are equal and the first index is smaller.
This function is only valid if both iterators point into the same matrix.

Comparison operator. Works in the same way as above operator, just the other way round.
