ArrangementInputFormatter

A model for the ArrangementInputFormatter concept supports a set of functions that enable reading an arrangement from an input stream using a specific format.

Types

ArrangementInputFormatter::Arrangement_2
	the type of arrangement to input.

typedef typename Arrangement_2::Point_2
	Point_2;	the point type.
typedef typename Arrangement_2::X_monotone_curve_2
	X_monotone_curve_2;	the $$x-monotone curve type.
typedef typename Arrangement_2::Size
	Size;
typedef typename Arrangement_2::Vertex_handle
	Vertex_handle;
typedef typename Arrangement_2::Halfedge_handle
	Halfedge_handle;
typedef typename Arrangement_2::Face_handle
	Face_handle;

Creation

ArrangementInputFormatter inf;
	default constructor.
ArrangementInputFormatter inf ( std::istream& is);
	constructs a formatter that reads from is.

void	inf.set_in ( std::istream& is)
		directs inf to read from is.

Access Functions

std::istream&

inf.in ()

returns the stream that inf reads from. Precondition: inf is directed to a valid output stream.
