GeometricChainComplex Concept Reference

Definition

The concept GeometricChainComplex refines the concept AbstractChainComplex and describes the requirements for (topological) chain complexes associated to geometric complexes used in the concept CGAL::HDVF. It adds to AbstractChainComplex methods to get vertices coordinates.

Types
typedef std::vector< double >	Point
	Type of coordinates (the vector size is free, hence coordinates can be any dimension).

Access functions
const std::vector< Point > &	get_vertices_coords () const
	Returns the vector of vertices coordinates.
Point	get_vertex_coords (size_t i) const
	Returns the coordinates of the cell of index i and dimension 0.
