ArrangementOutputFormatter Concept Reference

Definition

A model for the ArrangementOutputFormatter concept supports a set of functions that enable writing an arrangement to an output stream using a specific format.

Has Models:

CGAL::Arr_text_formatter<Arrangement>

CGAL::Arr_face_extended_text_formatter<Arrangement>

CGAL::Arr_extended_dcel_text_formatter<Arrangement>

Types
typedef unspecified_type	Arrangement_2
	the type of arrangement to output.
typedef Arrangement_2::Point_2	Point_2
	the point type.
typedef Arrangement_2::X_monotone_curve_2	X_monotone_curve_2
	the \( x\)-monotone curve type.
typedef Arrangement_2::Size	Size
typedef Arrangement_2::Vertex_const_handle	Vertex_const_handle
typedef Arrangement_2::Halfedge_const_handle	Halfedge_const_handle
typedef Arrangement_2::Face_const_handle	Face_const_handle

Creation
	Arr_out_formatter ()
	default constructor.
	Arr_out_formatter (std::ostream &os)
	constructs a formatter that writes to os.
void	set_out (std::ostream &os)
	directs outf to write to os.

Access Functions
std::ostream &	out ()
	returns the stream that outf writes to.
