CGAL 5.6  2D Arrangements

Operations  
Comparison_result  operator() (ArrTraits::X_monotone_curve_2 xc1, ArrTraits::X_monotone_curve_2 xc2, ArrTraits::Point_2 p) 
accepts two \(x\)monotone curves xc1 and xc2 that have a common left endpoint p , and returns CGAL::SMALLER, CGAL::EQUAL or CGAL::LARGER according to the relative position of the two curves immediately to the right of \(p\). More...  
Comparison_result ArrTraits::CompareYAtXRight_2::operator()  (  ArrTraits::X_monotone_curve_2  xc1, 
ArrTraits::X_monotone_curve_2  xc2,  
ArrTraits::Point_2  p  
) 
accepts two \(x\)monotone curves xc1
and xc2
that have a common left endpoint p
, and returns CGAL::SMALLER, CGAL::EQUAL
or CGAL::LARGER
according to the relative position of the two curves immediately to the right of \(p\).
Note that in case one of the \(x\)monotone curves is a vertical segment emanating upward from p
, it is always considered to be above the other curve.
