CGAL::Level_interval<FaceHandle>

Definition

The class Level_interval<FaceHandle> represents intervals for the minimum and maximum value of the z-coordinate of a face of a triangulation.

#include <CGAL/Level_interval.h>

Requirements

The value_type of FaceHandle must be Face, which must have a nested type Vertex, which must have a nested type Point, whose Kernel_traits<Point>Kernel must have a nested type FT. These requirements are fulfilled, if one uses a CGAL triangulation and a CGAL kernel.

Types

typedef FT Value; The type of the z-coordinate of points stored in vertices of faces.

Creation

Level_interval<FaceHandle> i;
Default constructor.


Level_interval<FaceHandle> i ( FaceHandle fh);
Constructs the interval with smallest and largest z coordinate of the points stored in the vertices of the face fh points to.

Operations

FaceHandle i.face_handle () returns the face handle.

I/O

ostream& ostream& os << i Inserts the interval i into the stream os.
Precondition: The output operator for *Face_handle is defined.

Is Model for the Concept
