public interface ILcdRing extends ILcdCurve
Note that this interface does not enforce this aspect:
it is the responsibility of the instance (e.g. ILcdGXYEditor) that creates or manipulates the
rings.
In addition to the invariants for a curve, a ring should have these:
ILcdCurveINTERPOLATION_CIRCLE_BY_3POINTS, INTERPOLATION_CIRCLE_BY_CENTERPOINT, INTERPOLATION_CIRCULARARC_BY_3POINTS, INTERPOLATION_CIRCULARARC_BY_BULGE, INTERPOLATION_CIRCULARARC_BY_CENTERPOINT, INTERPOLATION_ELLIPTICAL, INTERPOLATION_GEODESIC, INTERPOLATION_LINEAR, INTERPOLATION_MIXED, INTERPOLATION_RHUMBcomputePointSFCT, getEndPoint, getEndTangent2D, getInterpolation, getLength2D, getLineSegmentIntersectionCount, getStartPoint, getStartTangent2D, getTangent2Dcontains2D, contains2D, contains3D, contains3D, getFocusPointgetBoundsclone
