## Definition

The class `Straight_skeleton_builder_traits_2` provides a model for the `StraightSkeletonBuilderTraits_2` concept which is the traits class required by the `Straight_skeleton_builder_2` algorithm class.

Template Parameters

  Kernel | a 2D CGAL Kernel, such as the `Exact_predicates_inexact_constructions_kernel` (recommanded)

It is unspecified which subset of the kernel is used into the output sequence and the returned iterator will be equal to `out`.

For any given input polygon, it in this traits class (and by extension in the builder class). This is to avoid restricting the choices in the implementation.

Is Model Of:

  `StraightSkeletonBuilderTraits_2`

  `DefaultConstructible`

  `CopyConstructible`
