## Kernel::OrientedSide_2

A model for this must provide:

Oriented_side

fo.operator() ( | Kernel::Circle_2 c, Kernel::Point_2 p)

|  | returns ON_ORIENTED_BOUNDARY, ON_NEGATIVE_SIDE, or the constant ON_POSITIVE_SIDE, depending on the position of p relative to the oriented circle c.
Oriented_side | fo.operator() ( Kernel::Line_2 l, Kernel::Point_2 p)
|  | returns ON_ORIENTED_BOUNDARY, ON_NEGATIVE_SIDE, or the constant ON_POSITIVE_SIDE, depending on the position of p relative to the oriented line l.

Oriented_side

fo.operator() ( | Kernel::Triangle_2 t, Kernel::Point_2 p)

|  | returns ON_ORIENTED_BOUNDARY, ON_NEGATIVE_SIDE, or the constant ON_POSITIVE_SIDE, depending on the position of p relative to the oriented triangle t.
