Curve
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 non-instantiable class.
Curve Properties
Curve has the coordinates of its points.
Curve is defined as a one-dimensional geometry.
Curve is simple if it does not pass through the same point twice.
Curve is closed if its start point is equal to its end point.
Curve is empty.
Curve consists of its two end points.
Curve that is simple and closed is a LinearRing.
