CGAL::Arr_polycurve_traits_2< SubcurveTraits_2 >::Construct_curve_2 Class Reference

#include <CGAL/Arr_polycurve_traits_2.h>

Definition

Construction functor of a general (not necessarily \(x\)-monotone) polycurve.

This functor constructs general polycurve. Its operator() is oveloaded to support various input types.

Note that the composing subcurves, depending on the SubcurveTraits_2, might not be \(x\)-monotone.

(

const Subcurve_2 &

subcurve

)

const

Obtain a polycurve that comprises of one given subcurve.

Parameters

subcurve

input subcurve.

Precondition

subcurve is not degenerated (not tested).

Returns

A polycurve with one subcurve, namely subcurve.

template<typename ForwardIterator >

Curve_2 CGAL::Arr_polycurve_traits_2< SubcurveTraits_2 >::Construct_curve_2::operator()	(	ForwardIterator	begin,
		ForwardIterator	end
	)		const

Construct a well-oriented polycurve from a range of either SubcurveTraits_2::Point_2 or SubcurveTraits_2::Curve_2.

Parameters

begin	iterator pointing to the first element in the range.
end	iterator pointing to the past-the-end element in the range.

Precondition

The given range form a continuous and well-oriented polycurve (not tested).

Contains no degenerated subcurves (not tested)

Returns

A polycurve using the corresponding construction implementation.
