Interface Circle2D
- All Superinterfaces:
- ClosedCurve2D, Curve2D, GeomObject, GeomObject2D
- All Known Implementing Classes:
- AbstractCircle2D, RatCircle2D, IntCircle2D
- public interface Circle2D
- extends ClosedCurve2D
This interface describes a two-dimensional circle. It provides a
method that returns a double-precision approximation of the squared
radius. Geometric tests should be performed through methods of
GeomTester2D.
