CGAL::operator<<
Definition
CGAL defines output operators for classes that are derived
from the class ostream. This allows to write to ostreams
as cout or cerr, as well as to strstreams
and fstreams.
The output operator is defined for all classes in the CGAL kernel and for the class Color as well.
Let os be an output stream.
|
ostream&
|
ostream& os
>>
Class c
|
Inserts object c in the stream os. Returns os.

Example
#include <CGAL/basic.h>
#include <iostream>
#include <fstream>
#include <CGAL/Cartesian.h>
#include <CGAL/Segment_2.h>
typedef CGAL::Point_2< CGAL::Cartesian<double> > Point;
typedef CGAL::Segment_2< CGAL::Cartesian<double> > Segment;
int main()
{
Point p(0,1), q(2,2);
Segment s(p,q);
CGAL::set_pretty_mode(std::cout);
std::cout << p << std::endl << q << std::endl;
std::ofstream f("data.txt");
CGAL::set_binary_mode(f);
f << s << p ;
return 1;
