ArrDirectionalTraits::ConstructOpposite_2 Concept Reference

Definition

Operations

A model of this concept must provide:

ArrDirectionalTraits::X_monotone_curve_2 operator() (ArrDirectionalTraits::X_monotone_curve_2 xc)
 accepts an \( x\)-monotone curve xc and returns its opposite curve, namely a curve whose graph is the same as xc's, and whose source and target are swapped with respect to xc's source and target.
