Definition

Introduction

A model for the VertexContainer_2 concept defines the requirements for a resizable container of 2D points. It is used to output the offset polygons generated by the Polygon_offset_builder_2<Ssds,Gt,Container> class.

Has Models:

CGAL::Polygon_2

Any standard BackInsertionSequence, such as std::vector, std::list or std::deque, with a value_type being a model of the Kernel::Point_2 concept.

Types

typedef unspecified_type Point_2
 A 2D point type used to represent a vertex. More...
 
typedef unspecified_type size_type
 A unsigned integral type that can represent the number of vertices in the container.
 

Creation

 VertexContainer_2 ()
 Default constructor.
 
size_type size () const
 Returns the number of vertices in the container.
 
void push_back (Point_2 const &v) const
 Adds the vertex v to the container, resizing its capacity if required.
