ArrTraits::CompareYAtXRight_2 Concept Reference

## Operations

A model of this concept must provide:

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 SMALLER, EQUAL or LARGER according to the relative position of the two curves immediately to the right of $$p$$. More...

## Member Function Documentation

 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 SMALLER, EQUAL or 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.
