## ◆ operator<<() [1/2]

template<typename Traits , typename Dcel >

std::ostream & CGAL::operator<< | ( | std::ostream & | os,
|  | const Arrangement_2< Traits, Dcel > & | arr
| ) |  |

`#include <CGAL/IO/Arr_iostream.h>`

Inserts the arrangement object `arr` into the output stream `os` using the output format defined by the `Arr_text_formatter` class.

Only the basic geometric and topological features of the arrangement are inserted. Auxiliary data that may be attached to the DCEL features is ignored.
