CGAL::Min_sphere_of_spheres_d_traits_2< K, FT, UseSqrt, Algorithm > Class Template Reference

#include <CGAL/Min_sphere_of_spheres_d_traits_2.h>

## Definition

The class Min_sphere_of_spheres_d_traits_2<K,FT,UseSqrt,Algorithm> is a model for concept MinSphereOfSpheresTraits.

It uses a pair of CGAL Point_2 and FT to represent circles.

Is Model Of:
MinSphereOfSpheresTraits

The last two template parameters, UseSqrt and Algorithm, have default arguments, namely CGAL::Tag_false and CGAL::Default_algorithm, respectively. The template parameters of class Min_sphere_of_points_d_traits_2<K,FT,UseSqrt,Algorithm> must fulfill the following requirements:

Template Parameters
 K must be a model for Kernel. FT is a number type, which fulfills the requirements of type FT of concept MinSphereOfSpheresTraits: It must be either double or float, or an exact number type. UseSqrt fulfills the requirements of type Use_square_roots of concept MinSphereOfSpheresTraits: It must be either Tag_true or Tag_false, and its default is Tag_false. Algorithm fulfills the requirements of type Algorithm of concept MinSphereOfSpheresTraits: It must be either Default_algorithm, LP_algorithm or Farthest_first_heuristic, and its default is Default_algorithm.
Examples:
Min_sphere_of_spheres_d/min_sphere_of_spheres_d_2.cpp.

## Constants

static const int D
is the constant 2, i.e. the dimension of $$\mathbb{R}^2$$.

## Types

In addition to the types required by the concept MinSphereOfSpheresTraits, this model also defines the types Radius and Point.

Here's the complete list of defined types:

typedef unspecified_type FT

typedef unspecified_type Use_square_roots

typedef unspecified_type Algorithm

is a typedef to the template parameter FT

typedef unspecified_type Point
is a typedef to K::Point_2.

typedef unspecified_type Sphere
is a typedef to std::pair<Point,Radius>.

typedef unspecified_type Cartesian_const_iterator
is a typedef to K::Cartesian_const_iterator_2.

## Access Functions

The class provides the access functions required by the concept MinSphereOfSpheresTraits; they simply map to the corresponding routines of class K::Point_2:

maps to s.second.
maps to s.first.cartesian_begin().
