CGAL::Arr_polyline_traits_2< SegmentTraits_2 >::Construct_curve_2 Class Reference

#include <CGAL/Arr_polyline_traits_2.h>

Definition

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

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

Note that the composing segments, depending on the SegmentTraits_2, might not be \(x\)-monotone.

Operations
Curve_2	operator() (const Point_2 &p, const Point_2 &q) const
	Obtain a polyline connecting the two given endpoints. More...
Curve_2	operator() (const Segment_2 &seg) const
	Obtain a polyline that comprises of one given segment. More...
template<typename ForwardIterator >
Curve_2	operator() (ForwardIterator begin, ForwardIterator end) const
	Construct a well-oriented polyline from a range of either SegmentTraits_2::Point_2 or SegmentTraits_2::Segment_2. More...

(

const Segment_2 &

seg

)

const

Obtain a polyline that comprises of one given segment.

Parameters

seg	input segment

Precondition

seg is not degenerated (not tested)

Returns

A polyline with one segment, namely seg.

template<typename SegmentTraits_2 >

template<typename ForwardIterator >

Curve_2 CGAL::Arr_polyline_traits_2< SegmentTraits_2 >::Construct_curve_2::operator()	(	ForwardIterator	begin,
		ForwardIterator	end
	)		const

Construct a well-oriented polyline from a range of either SegmentTraits_2::Point_2 or SegmentTraits_2::Segment_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 polyline (not tested).

Contains no degenerated segments (not tested)

Returns

A polyline using the corresponding construction implementation.
