`#include <CGAL/Manhattan_distance_iso_box_point.h>`

## Definition

The class `Manhattan_distance_iso_box_point` provides an implementation of the `GeneralDistance` concept for the Manhattan distance ( \( l_1\) metric) between a `d`-dimensional iso-box and a `d`-dimensional point and the Manhattan distance between a `d`-dimensional iso-box and a `d`-dimensional iso-box defined as a `k-d` tree rectangle.

Template Parameters

  Traits | must be a model for the concept `SearchTraits`, for example `Search_traits_3<Simple_cartesian<double> >`.

Is Model Of:
  `GeneralDistance`

See Also
  `GeneralDistance`

Examples:
  Spatial_searching/general_neighbor_searching.cpp.

## Operations

FT | transformed_distance (Query_item b, Point_d p) const
| Returns the transformed distance between `b` and `p`.
FT | transformed_distance (FT d) const
| Returns the transformed value of of `d`.
FT | inverse_of_transformed_distance (FT d) const
| Returns the value of the inverse of the transform function applied to `d`.
FT | min_distance_to_rectangle (Query_item b, Kd_tree_rectangle< FT, D > r) const
| Returns the minimal distance between a point from `b` and a point from `r`.
FT | max_distance_to_rectangle (Query_item b, Kd_tree_rectangle< FT, D > r) const
| Returns the maximal distance between the iso-box `b` and a point from `r` furthest to `b`.
