CGAL::Line_arc_2< CircularKernel > Class Template Reference

#include <CGAL/Line_arc_2.h>

Definition

template<typename CircularKernel>
class CGAL::Line_arc_2< CircularKernel >

Is model of

CircularKernel::LineArc_2

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.
