CGAL 5.4.4  2D Polyline Simplification

Models of this concept are passed to the polyline simplification algorithm to indicate when to stop the process.

Indicates if the simplification must be stopped.
This is called right before each vertex is about to be removed.
ct  The underlying constrained Delaunay triangulation which embeds the polyline constraints 
q  The current vertex about to be removed 
cost  The associated cost for removing the current vertex (as given by PolylineSimplificationCostFunction ) 
initial_count  The initial number of vertices in the entire polyline set (including intersection vertices not in any source polyline) 
current_count  The current number of vertices 
true
if the algorithm should stop, false
if it should continue. CDT  must be CGAL::Constrained_triangulation_plus_2 with a vertex type that is model of PolylineSimplificationVertexBase_2 .
