CGAL::Arr_polyline_traits_2< SegmentTraits_2 >::Construct_x_monotone_curve_2 Class Reference

`#include <CGAL/Arr_polyline_traits_2.h>`

## Definition

Construction functor of \(x\)-monotone polyline.

Similar to `Construct_curve_2`, only returns \(x\)-monotone polylines. Thus, have the same overloads of the `operator()`. Note that when constructing `X_monotone_curve_2` all preconditions are tested.

If `CGAL_ALWAYS_LEFT_TO_RIGHT` is defined, then the resulting \(x\)-monotone polyline will be oriented from left-to-right.
