## Definition

template<typename GeomTraits>
class CGAL::Search_traits_3< GeomTraits >

The class `Search_traits_3` can be used as a template parameter of the kd tree and the search classes.

Template Parameters

  GeomTraits | must be a model of the concept `SearchGeomTraits_3`, for example `Simple_cartesian<double>` or `Simple_cartesian<Gmpq>`.

Is model of
  `SearchTraits`
  `RangeSearchTraits`

## ◆ Construct_cartesian_const_iterator_d

template<typename GeomTraits >

typedef GeomTraits::Construct_cartesian_const_iterator_3 CGAL::Search_traits_3< GeomTraits >::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`.
