CGAL::Dimension_tag<int dim>
Definition
An object of the class Dimension_tag<int dim> is an empty object which can be used
for dispatching functions based on the dimension of an object, as provided
by the dim parameter. It is useful in cases where it is not more
practical to pass the dimension as a template parameter directly.
#include <CGAL/Dimension.h>
Constants

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); }
std::cout << get_origin(Dimension_tag<2>())) << std::endl;
