Class

CGAL::Search_traits_2<Kernel>

Definition

The class Search_traits_2<Kernel> can be used as a template parameter of the kd tree and the search classes.

#include <CGAL/Search_traits_2.h>

Parameters

Expects for the template argument a model of the concept Kernel, for example CGAL::Cartesian<double> or CGAL::Simple_cartesian<CGAL::Gmpq>.

Is Model for the Concepts

SearchTraits and RangeSearchTraits.

Types

Kernel::FT FT; Number type.

Kernel::Point_2 Point_d; Point type.

Kernel::Iso_rectangle_2 Iso_box_d; Iso box type.

Kernel::Sphere_2 Sphere_d; Sphere type.

Kernel::Cartesian_const_iterator_2
Cartesian_const_iterator_d; An iterator over the Cartesian coordinates.

Kernel::Construct_cartesian_const_iterator_2
Construct_cartesian_const_iterator_d;
A functor with two function operators, which return the begin and past the end iterator for the Cartesian coordinates. The functor for begin has as argument a Point_d. The functor for the past the end iterator, has as argument a Point_d and an int.

Kernel::Construct_iso_rectangle_2 Construct_iso_box_d; Functor with operator to construct the iso box from two points.

Kernel::Construct_center_2 Construct_center_d; Functor with operator to construct the center of an object of type Sphere_d.

Kernel::Compute_squared_radius_2 Construct_squared_radius_d; Functor with operator to compute the squared radius of a an object of type Sphere_d.

Kernel::Construct_min_vertex_2 Construct_min_vertex_d; Functor with operator to construct the vertex with lexicographically smallest coordinates of an object of type Iso_box_d.

Kernel::Construct_max_vertex_2 Construct_max_vertex_d; Functor with operator to construct the vertex with lexicographically largest coordinates of an object of type Iso_box_d.
