Direct Known Subclasses:

LineStringExpression

public abstract class CurveExpression<T extends org.geolatte.geom.Geometry>
extends GeometryExpression<T>

A Curve is a 1-dimensional geometric object usually stored as a sequence of Points, with the subtype of Curve specifying the form of the interpolation between Points. This standard defines only one subclass of Curve, LineString, which uses linear interpolation between Points.
