Hello,

 

I tried using the function CGAL::decompose in Arr_vertical_decomposition.h while having defined VERBOSE in Basic_sweep_line_2.h. This didn´t compile, because the operator<< is not defined in Arr_batched_point_location_meta_traits.h, which is used by Arr_vertical_decomposition.h.

 

I nicked the following definitions from Arr_overlay_2/Overlay_meta_traits.h and included them in Arr_batched_point_location_meta_traits.h:

 

 

friend std::ostream& operator<< (std::ostream& os, const My_Point_2 & p)

{

os << p.base_point();

return (os);

}

 

 

friend std::ostream& operator<< (std::ostream& os, const My_X_monotone_curve_2 & cv)

{

os << cv.base_curve();

return (os);

}

 

Maybe you want to include this in the next release, might be helpful to others as well. 

 

Kind regards,

 

Jannis Warnat
