#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.

Constructor & Destructor Documentation

◆ Line_arc_2()

template<typename CircularKernel>
CGAL::Line_arc_2< CircularKernel >::Line_arc_2 ( const Line_2< CircularKernel > & l,
const Circular_arc_point_2< CircularKernel > & p1,
const Circular_arc_point_2< CircularKernel > & p2 )

Construct the line segment supported by l, whose source is p1 and whose target is p2.

Precondition
p1 and p2 lie on l.

◆ operator==()

template<typename CircularKernel>
bool operator== ( const Line_arc_2< CircularKernel > & la1,
const Line_arc_2< CircularKernel > & la2 )
related

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.
