ArrangementOutputFormatter Concept Reference
2D Arrangement Reference » Concepts

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. More...

◆ out()

std::ostream& ArrangementOutputFormatter::out ( )

returns the stream that outf writes to.

Precondition
outf is directed to a valid output stream.
