CGAL 5.3 - 2D Arrangements
CGAL::Arr_open_side_tag Struct Reference

#include <CGAL/Arr_tags.h>


All the four types Left_side_category, Right_side_category, Bottom_side_category, and Top_side_category nested in any model of the concept ArrangementOpenBoundaryTraits must be convertible to Arr_open_side_tag, which derives from Arr_oblivious_side_tag.

It implies that some curves are expected to approach the left, right, bottom, or top sides of the open boundary of the parameter space. Arr_open_side_tag is an empty construct used for dispatching functions based on type of curves that induce the arrangement.
