PolylineSimplificationVertexBase_2 Concept Reference
Concepts

## Definition

The polyline simplification algorithm stores in the vertices whether a vertex can be removed, and the cost of the removal.

Refines:
  `TriangulationVertexBase_2`

### Types

Defines the same types as the `TriangulationVertexBase_2` concept

Has Models:
  `CGAL::Polyline_simplification_2::Vertex_base_2<Vb>`

See Also
  `TriangulationFaceBase_2`
  `CGAL::Constrained_triangulation_plus_2<Tr>`

## Public Types

typedef unspecified_type | FT
| A number type which must be the same as the `FT` of the geometric traits class of the triangulation.

## Access Functions

bool | is_removable () const
| indicates whether the vertex can be removed.
void | set_removable (bool b)
| allows to set whether the vertex can be removed.
FT | cost () const
| returns the cost of the vertex removal.
void | set_cost (const FT &ft)
| allows to set the cost of the vertex removal.
