Definition

The concept FrechetDistanceTraits defines the requirements of the first template parameter of the functions CGAL::is_Frechet_distance_larger() and CGAL::approximate_Frechet_distance().

Member Typedef Documentation

The point type of the exact kernel corresponding to dimension.

The point type must have operator[] returning a number type which can be used as first template parameter of Sqrt_extension.

The kernel type.

If this type has a nested type Has_filtered_predicates_tag with value == true,
