Constructor & Destructor Documentation

◆ X_monotone_curve_2() [1/3]

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 ( X_monotone_segment_2  seg)

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.

Member Function Documentation

◆ number_of_segments()

template<typename SegmentTraits_2 >
Segments_size_type CGAL::Arr_polyline_traits_2< SegmentTraits_2 >::X_monotone_curve_2::number_of_segments ( ) const

Obtain the number of subcurves that comprise the poyline.

Returns
The number of subcurves.
