## PlanarMapDcelVertex_2

The PlanarMapDcelVertex_2 concpet is a refinement of the TopologicalMapDcelVertex concept. The requirements of the latter are the requirements of the former. In addition the PlanarMapDcelVertex_2 should contain the following geometric types and methods.

### Types

PlanarMapDcelVertex_2::Point
| a point associated with the vertex.

### Operations

Point | v.point () | the point.
void | v.set_point ( Point p)
|  | set the point in v to p.
