Interface OrientableCurve

All Superinterfaces:

Curve, GeometricPrimitive, Geometry, GMLObject, Object, TypedObjectNode

All Known Implementing Classes:

DefaultOrientableCurve

public interface OrientableCurve
extends Curve

An OrientableCurve consists of a wrapped base Curve and an additional orientation.

If the orientation is *not* reversed, then the OrientableCurve is identical to the base curve. If the orientation is reversed, then the OrientableCurve is related to the base curve with a parameterization that reverses the sense of the curve traversal.
