CGAL 5.4 - 2D Arrangements
CGAL::Arr_closed_side_tag Struct Reference

#include <CGAL/Arr_tags.h>

Definition

This type tag is used to indicate that a side of the parameter space, either left, right, bottom, or top, is closed, and curves that reach this side might be inserted into the arrangement.

More precisely, when this condition occurs at the left, right, bottom, or top side, then the corresponding categories, namely, Left_side_category, Right_side_category, Bottom_side_category, and Top_side_category, nested in every geometry traits class, must be convertible to the type Arr_closed_side_tag. At this point none of the traits provided with the 2D Arrangements package supports this condition

Arr_oblivious_side_tag is an empty construct used for dispatching functions based on type of curves that induce the arrangement.
