Definition

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.

Types
typedef unspecified_type	Periodic_2_offset_2
	A model of the concept `Periodic_2Offset_2`

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.
