Constructor & Destructor Documentation

template<typename SegmentTraits_2 >

template<typename InputIterator >

void CGAL::Arr_polyline_traits_2< SegmentTraits_2 >::Curve_2::Curve_2	(	InputIterator	begin,
		InputIterator	end
	)

constructs a polyline from a range of subcurves.

Parameters

begin	An iterator pointing to the first subcurve in the range.
end	An iterator pointing after the past-the-end subcurve in the range.

Precondition: The end of subcurve n should be the beginning of subcurve n+1.

template<typename SegmentTraits_2 >

Segments_size_type CGAL::Arr_polyline_traits_2< SegmentTraits_2 >::Curve_2::number_of_segments ( ) const

Obtain the number of subcurves that comprise the poyline.
