ArrangementInputFormatter Concept Reference

Definition

A model for the ArrangementInputFormatter concept supports a set of functions that enable reading an arrangement from an input 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 input.
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_handle	Vertex_handle
typedef Arrangement_2::Halfedge_handle	Halfedge_handle
typedef Arrangement_2::Face_handle	Face_handle

Creation
	Arr_in_formatter ()
	default constructor.
	Arr_in_formatter (std::istream &is)
	constructs a formatter that reads from is.
void	set_in (std::istream &is)
	directs inf to read from is.

Access Functions
std::istream &	in ()
	returns the stream that inf reads from. More...
