 Compares the Cartesian \( y\)-coordinates of points p and q
 
Comparison_result operator() (const Kernel::Point_2 &p, const Kernel::Line_2 &l1, const Kernel::Line_2 &l2)
 compares the \( y\)-coordinates of p and the intersection of lines l1 and l2. More...
 
Comparison_result operator() (const Kernel::Line_2 &l, const Kernel::Line_2 &h1, const Kernel::Line_2 &h2)
 compares the \( y\)-coordinates of the intersection of line l with line h1 and with line h2. More...
 
Comparison_result operator() (const Kernel::Line_2 &l1, const Kernel::Line_2 &l2, const Kernel::Line_2 &h1, const Kernel::Line_2 &h2)
