CGAL 6.0 - 2D Periodic Triangulations
|
A refinement of the concept TriangulationVertexBase_2 which adds an API for offset.
At the base level of 2D-triangulations (see Section Software Design), a vertex provides access to one of its incident faces through a handle.
The storage of the offset is only needed when a triangulation is copied.

Access Functions | |
| Periodic_2_offset_2 | offset () const |
| Returns the offset stored in the vertex. | |
| bool | get_offset_flag () const |
Returns true if the offset has been set, false otherwise. | |
| void | set_offset (Periodic_2_offset_2 o) |
Sets the offset and sets the offset flag to true. | |
| void | clear_offset () |
Sets the offset flag to false and clears the offset. | |
