CGAL 5.5 - 2D Arrangements
|
#include <CGAL/Arr_tags.h>
This type tag is used to indicate that the condition of a boundary side of the parameter space is irrelevant.
More precisely, when curves inserted into the arrangement are never expected to reach a boundary side, either left, right, bottom, or top, 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_oblivious_side_tag
.
Arr_oblivious_side_tag
is an empty construct used for dispatching functions based on type of curves that induce the arrangement.
