ArrTraits::CompareYAtXLeft_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 right endpoint p, and returns SMALLER, EQUAL or LARGER according to the relative position of the two curves immediately to the left of $$p$$. More...

◆ operator()()

 Comparison_result ArrTraits::CompareYAtXLeft_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 right endpoint p, and returns SMALLER, EQUAL or LARGER according to the relative position of the two curves immediately to the left of $$p$$.

Note that in case one of the $$x$$-monotone curves is a vertical segment (emanating downward from p), it is always considered to be below the other curve.
