The class Straight_skeleton_halfedge_base_2<Refs> provides a model for the StraightSkeletonHalfedge_2 concept which is the halfedge type required by the StraightSkeleton_2 concept. The class Straight_skeleton_halfedge_base_2<Refs> has only one template argument: 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.
