CGAL::Dynamic_dimension_tag Struct Reference

#include <CGAL/Dimension.h>

Definition

An object of the class Dynamic_dimension_tag is an empty object which can be used for dispatching functions based on the dimension of an object.

Dynamic_dimension_tag indicates that the dimension is not known at compile-time. Dimension_tag is the tag class dealing with compile-time dimensions.

Example

The following code declares two functions constructing two points at the origin, either in 2D or in 3D.

Point_2<K> get_origin(Dimension_tag<2>) { return Point_2<K>(ORIGIN); }
Point_3<K> get_origin(Dimension_tag<3>) { return Point_3<K>(ORIGIN); }
Point_d<K> get_origin(Dynamic_dimension_tag) { return Point_d<K>(ORIGIN); }
 
std::cout << get_origin(Dynamic_dimension_tag())) << std::endl;
