template<typename SegmentTraits_2 >

CGAL::Arr_polyline_traits_2< SegmentTraits_2 >::X_monotone_curve_2::X_monotone_curve_2

Construct default.

X_monotone_curve_2() [2/3]

template<typename SegmentTraits_2 >

CGAL::Arr_polyline_traits_2< SegmentTraits_2 >::X_monotone_curve_2::X_monotone_curve_2

(

Construct from a subcurve.

X_monotone_curve_2() [3/3]

template<typename SegmentTraits_2 >

template<typename InputIterator >

CGAL::Arr_polyline_traits_2< SegmentTraits_2 >::X_monotone_curve_2::X_monotone_curve_2	(	InputIterator	begin,
		InputIterator	end
	)

Construct from a range.

Similar to the constructor of a general polycurve. Like in the case of general polycurve, for the sake of backwards compatibility we have to keep an implementation of construction from a range of points. DO NOT USE THIS CONSTRUCTION.

const

Obtain the number of subcurves that comprise the poyline.

Returns
