StraightSkeleton_2 Concept Reference

Definition

The concept StraightSkeleton_2 describes the requirements for the data structure used to represent a straight skeleton. It refines the concept HalfedgeDS and adds additional requirements on the nested types Vertex, Halfedge, and Face of the halfedge data structure.

Refines:

HalfedgeDS

Has Models:

CGAL::Straight_skeleton_2

Attention

This concept explicitly protects all the modifying operations of the base HalfedgeDS concept. Only the algorithm classes, or clients explicitly bypassing the protection mechanism, can modify a straight skeleton.

Types
typedef unspecified_type	Vertex
	A model of the StraightSkeletonVertex_2 concept used to represent the vertices of the straight skeleton.
typedef unspecified_type	Halfedge
	A model of the StraightSkeletonHalfedge_2 concept used to represent the halfedges of the straight skeleton.
typedef unspecified_type	Face
	Any model of the StraightSkeletonFace_2 concept used to represent the faces of the straight skeleton.
