## Kernel::HasOnBoundary_2

A model for this must provide:

bool

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

|  | returns true iff p lies on the boundary of c.

bool

fo.operator() ( | Kernel::Iso_rectangle_2 i, Kernel::Point_2 p)

|  | returns true iff p lies on the boundary of i.

bool

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

|  | returns true iff p lies on the boundary of t.
