CGAL::Straight_skeleton_converter_2< SrcSs, TgtSs, ItemsCvt > Struct Template Reference

#include <CGAL/Straight_skeleton_converter_2.h>

Definition

The class Straight_skeleton_converter_2 converts a straight skeleton instantiated using certain traits into another straight skeleton instantiated using a different traits.

The third template parameter ItemsConverter is a function object that must

Template Parameters

SrcSs	type of the source straight skeleton
TgtSs	type of the target straight skeleton
ItemsCvt	a model StraightSkeletonItemsConverter_2. The default value of this parameter is Straight_skeleton_items_converter_2<SrcSs,TgtSs>.

This conversion can be used to produce a straight skeleton with the fast Exact_predicates_inexact_constructions_kernel but then input that skeleton into Polygon_offset_builder<Ss,Gt,Container> instantiated with the slower Exact_predicates_exact_constructions_kernel obtaining only simple offset polygons without paying the runtime overhead of exact constructions for the straight skeleton itself.

Types
SrcSs	Source_skeleton
	The SrcSs template parameter corresponding to the source straight skeleton.
TgtSs	Target_skeleton
	The TgtSs template parameter corresponding to the target straight skeleton.
ItemsCvt	Items_converter
	The ItemsCvt template parameter corresponding to the items converter.

Creation
	Straight_skeleton_converter_2 (Items_converter const &c)
	Default constructor .

Operations
boost::shared_ptr< Target_skeleton >	operator() (Source_skeleton const &s) const
	returns a new straight skeleton data structure with the same combinatorial and geometric data as s using the items converter to convert the geometric embeeding to the types of the target traits.
