## ◆ Construct_cartesian_const_iterator_d

template<typename SearchGeomTraits >
 typedef SearchGeomTraits::Construct_cartesian_const_iterator_2 CGAL::Search_traits_2< SearchGeomTraits >::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.
