#include <CGAL/Line_arc_2.h>
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.

p1 and p2 lie on l.

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.
