CGAL 5.5.1 - 2D Polyline Simplification
PolylineSimplificationVertexBase_2 Concept Reference

## Definition

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

## 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.
