CGAL::Straight_skeleton_converter_2< Source_skeleton_, Target_skeleton_, Items_converter_ > Struct Template Reference

#include <CGAL/Straight_skeleton_converter_2.h>

Definition

template<typename Source_skeleton_, typename Target_skeleton_, typename Items_converter_>
struct CGAL::Straight_skeleton_converter_2< Source_skeleton_, Target_skeleton_, Items_converter_ >

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

Template Parameters

Source_skeleton_	type of the source straight skeleton
Target_skeleton_	type of the target straight skeleton
Items_converter_	a model StraightSkeletonItemsConverter_2. The default value of this parameter is Straight_skeleton_items_converter_2<Source_skeleton_,Target_skeleton_>.

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

Types
typedef Source_skeleton_	Source_skeleton
	The Source_skeleton_ template parameter corresponding to the source straight skeleton.
typedef Target_skeleton_	Target_skeleton
	The Target_skeleton_ template parameter corresponding to the target straight skeleton.
typedef Items_converter_	Items_converter
	The ItemsCvt template parameter corresponding to the items converter.

Creation
	Straight_skeleton_converter_2 (const Items_converter &c=Items_converter())
	Default constructor .

Operations
std::shared_ptr< Target_skeleton >	operator() (const Source_skeleton &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.
