11.4.2.4 Curve Class
A Curve is a one-dimensional geometry, usually represented by a sequence of points. Particular subclasses of Curve define the type of interpolation between points. Curve is a noninstantiable class.
Curve Properties
A
Curvehas the coordinates of its points.A
Curveis defined as a one-dimensional geometry.A
Curveis simple if it does not pass through the same point twice, with the exception that a curve can still be simple if the start and end points are the same.A
Curveis closed if its start point is equal to its endpoint.The boundary of a closed
Curveis empty.The boundary of a nonclosed
Curveconsists of its two endpoints.A
Curvethat is simple and closed is aLinearRing.
