CGAL 4.12.1 - 2D Circular Geometry Kernel
|
#include <CGAL/Line_arc_2.h>
I/O
The format for input/output is, for each line arc: a Line_2
(the supporting line) and two Circular_arc_point_2
(the two endpoints), under the condition that the endpoints are actually lying on the line.

Test for equality.
Two arcs are equal, iff their non-oriented supporting lines are equal (i.e. they contain the same set of points) and their endpoints are equal.
