Has Models:
ArrangementBasicTraits_2::Compare_y_at_x_2

Operations

A model of this concept must provide:

Comparison_result operator() (ArrTraits::Point_2 p, ArrTraits::X_monotone_curve_2 xc)
 compares the \( y\)-coordinates of p and the vertical projection of p on xc, and returns SMALLER, EQUAL, or LARGER according to the result.
