13.4.2.4 Curve Class

ACurve is a one-dimensional geometry, usually represented by a sequence of points. Particular subclasses ofCurve define the type of interpolation between points.Curve is a noninstantiable class.

Curve Properties

  • ACurve has the coordinates of its points.

  • ACurve is defined as a one-dimensional geometry.

  • ACurve is 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.

  • ACurve is closed if its start point is equal to its endpoint.

  • The boundary of a closedCurve is empty.

  • The boundary of a nonclosedCurve consists of its two endpoints.

  • ACurve that is simple and closed is aLinearRing.
