CGAL::Feature_dimension< T, K > Struct Template Reference

#include <CGAL/Dimension.h>

Definition

template<typename T, typename K = typename Kernel_traits<T>::Kernel>
struct CGAL::Feature_dimension< T, K >

The class Feature_dimension allows to retrieve the geometric dimension of a type T in a kernel K.

Parameters

The parameter K has the default value Kernel_traits<T>Kernel.

Example

The following retrieves the dimension of a point type.

typedef K::Point_2 Point; 
int dimension = Feature_dimension<Point, K>::value; 
assert(dimension == 0);

type

template<typename T , typename K = typename Kernel_traits<T>::Kernel>

typedef unspecified_type CGAL::Feature_dimension< T, K >::type

Either Dimension_tag<dim> if the dimension is a compile-time constant of value dim, or Dynamic_dimension_tag otherwise.

It is implemented as K::Feature_dimension<T>::type.

value

template<typename T , typename K = typename Kernel_traits<T>::Kernel>

const int CGAL::Feature_dimension< T, K >::value

static

The dimension value as a compile-time integral constant.

It is implemented as K::Feature_dimension<T>::type::value. It exists only when the dimension is a compile-time constant.
