#include <deal.II/grid/tria_iterator_selector.h>
This class implements some types which differ between the dimensions. These are the declarations for the 1D case only. See the Iterators on mesh-like containers module for more information.
A vertex_iterator
is typedef'd to an iterator operating on the vertices
member variable of a Triangulation<1>
object.
A line_iterator
is typedef'd to an iterator operating on the lines
member variable of a Triangulation<1>
object. An active_line_iterator
only operates on the active lines. raw_line_iterator
objects operate on all lines, used or not.
Since we are in one dimension, the following identities are declared:
To enable the declaration of begin_quad
and the like in Triangulation<1>
, the quad_iterators
are declared as iterators over InvalidAccessor. Thus these types exist, but are useless and will certainly make any involuntary use visible. The same holds for hexahedron iterators.
The same applies for the face_iterator
types, since lines have no substructures apart from vertices, which are handled in a different way, however.
