## Definition

template<typename NT, typename Point, typename CartesianIterator, typename ConstructCartesianIterator, typename Dim>
class CGAL::Search_traits< NT, Point, CartesianIterator, ConstructCartesianIterator, Dim >

The class `Search_traits` can be used as a template parameter of the kd tree and the search classes.

It is a mere wrapper for the geometric types needed by these classes.

Is model of
  `SearchTraits`

## Types
typedef Dim | Dimension
| Dimension type.
typedef NT | FT
| The number type of the coordinates.
typedef Point | Point_d
| Point type.
typedef CartesianIterator | Cartesian_const_iterator_d
| An iterator over the coordinates.
typedef ConstructCartesianIterator | Construct_Cartesian_const_iterator_d
| A functor with two function operators, which return the begin and past the end iterator for the Cartesian coordinates.

## Member Typedef Documentation

## ◆ Construct_Cartesian_const_iterator_d

template<typename NT , typename Point , typename CartesianIterator , typename ConstructCartesianIterator , typename Dim >

typedef ConstructCartesianIterator CGAL::Search_traits< NT, Point, CartesianIterator, ConstructCartesianIterator, Dim >::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`.

## ◆ Dimension

template<typename NT , typename Point , typename CartesianIterator , typename ConstructCartesianIterator , typename Dim >

typedef Dim CGAL::Search_traits< NT, Point, CartesianIterator, ConstructCartesianIterator, Dim >::Dimension

Dimension type.

Either `Dimension_tag<int dim>` or `Dynamic_dimension_tag`.
