I/O

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

## Definition

`Arr_face_extended_text_formatter` defines the format of an arrangement in an input or output stream (typically a file stream), thus enabling reading and writing an `Arrangement` instance using a simple text format.

The `Arrangement` class should be instantiated with a Dcel class which in turn instantiates the `Arr_face_extended_dcel` template with a `FaceData` type. The formatter supports reading and writing the data objects attached to the arrangement faces as well.

The `Arr_face_extended_text_formatter` class assumes that the nested `Point_2` and the `Curve_2` types defined by the `Arrangement` template-parameter and that the `FaceData` type can all be written to an input stream using the `<<` operator and read from an input stream using the `>>` operator.

Is Model Of:

  `ArrangementInputFormatter`

  `ArrangementOutputFormatter`
