## Definition

The class `Periodic_2_triangulation_hierarchy_vertex_base_2` is designed to be used as a vertex base class of a triangulation plugged into a `Periodic_2_triangulation_hierarchy_2<Tr>`.

It is a model of the concept `TriangulationHierarchyVertexBase_2` which refines the concept `TriangulationVertexBase_2` and of the concept `Periodic_2_triangulation_vertex_base_2`.

This class is templated by a parameter `Vb` which is to be instantiated by a model of the concept `Periodic_2TriangulationVertexBase_2`. The class `Periodic_2_triangulation_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.

Is Model Of:

  `TriangulationHierarchyVertexBase_2`

  `Periodic_2TriangulationVertexBase_2`
