#include <CGAL/Integer_grid_snap_rounding_traits_2.h>

Inherits from

CGAL::Arr_segment_traits_2< Exact_predicates_exact_constructions_kernel >.

Definition

template<typename InputKernel, typename ExactKernel = Exact_predicates_exact_constructions_kernel>
struct CGAL::Integer_grid_snap_rounding_traits_2< InputKernel, ExactKernel >

The class Integer_grid_snap_rounding_traits_2<InputKernel, ExactKernel> is a model of the VerticalSlabSnapRoundingTraits_2 concept.

It is identical to Double_grid_snap_rounding_traits_2<InputKernel, ExactKernel>, except that points are rounded to the closest point with integer coordinates.

Template Parameters

InputKernel	specifies the kernel used for the input geometric objects. It must model the CGAL Kernel concept. These objects must be convertible to and from the types defined by ExactKernel using CGAL::Cartesian_converter.
ExactKernel	specifies the exact kernel used internally to compute intersections and subdivision points before to round them. It must model the CGAL Kernel concept.

Is model of

VerticalSlabSnapRoundingTraits_2
