CGAL 5.1.3  2D Triangulation

#include <CGAL/Triangulation_hierarchy_2.h>
Vb.
The class Triangulation_hierarchy_vertex_base_2
is designed to be used as a vertex base class of a triangulation plugged into a Triangulation_hierarchy_2<Tr>
.
It is a model of the concept TriangulationHierarchyVertexBase_2
which refines the concept TriangulationVertexBase_2
.
This class is templated by a parameter Vb
which is to be instantiated by a model of the concept TriangulationVertexBase_2
. The class Triangulation_hierarchy_vertex_base_2<Vb>
inherits from the class Vb
. This design allows to use either the default vertex base class or a user customized vertex base with additional functionalities.
