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 HDVF. It adds to AbstractChainComplex methods to get vertex coordinates.

Types
typedef unspecified_type	Point
	Type of coordinates (the vector size is free, hence coordinates can be any dimension).

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