CGAL 5.5.2 - 2D Arrangements
ArrangementHorizontalSideTraits_2 Concept Reference

Definition

ArrangementHorizontalSideTraits_2 is an abstract concept. It generalizes all concepts that handle curves that either reach or approach either the bottom or top sizeds of the boundary of the parameter space. (An "abstract" concept is a concept that is useless on its own.) Only a combination of this concept and one or more concepts that handle curves that either reach or approach the remaining boundary sides (that is, left and right) are purposeful, and can have models.
