VertexContainer_2 Concept Reference

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. More...

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