TopologyContainer Class Reference

#include <generic_components.h>

Detailed Description

A class that represents a Topology set indices. It is composed by 3 arrays, a linear list of point indices, list of offsets that split the point list in outlines, and a list of the groups outline in complex elements (like a polygon with holes). It can also represents as set of line outlines, in which case the groups array will not be used and the closed array will containe the close status for each outline.
