The class Straight_skeleton_vertex_base_2<Refs,Point,FT> provides a model for the StraightSkeletonVertex_2 concept which is the vertex type required by the StraightSkeleton_2 concept. The class Straight_skeleton_vertex_base_2<Refs,Point,FT> has three template arguments: the first is the model of the StraightSkeleton_2 concept (the vertex container), the second is a Point type, and the third is a model of the SqrtFieldNumberType, which is the numeric type used to represent the time of a vertex (a Euclidean distance).
This class can be used as a base class allowing users of the straight skeleton data structure to decorate a vertex with additional data. The concrete vertex 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.
