◆ Curve_2()

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.

beginAn iterator pointing to the first subcurve in the range.
endAn iterator pointing after the past-the-end subcurve in the range.
The end of subcurve n should be the beginning of subcurve n+1.
