## Definition

The class `Straight_skeleton_halfedge_base_2` provides a model for the `StraightSkeletonHalfedge_2` concept which is the halfedge type required by the `StraightSkeleton_2` concept.

Template Parameters

  Refs | a model of the `StraightSkeleton_2` concept (the halfedge container)

This class can be used as a base class allowing users of the straight skeleton data structure to decorate a halfedge with additional data. The concrete halfedge class must be given in the `HalfedgeDSItems` template parameter of the instantiation of the `HalfedgeDS_default` class used as the model for the `Straight_skeleton_2` concept.

Is Model Of:

  `StraightSkeletonHalfedge_2`

  `DefaultConstructible`

  `CopyConstructible`

  `Assignable`
