/*! |
* The Curve class is used by LineString as parent class. |
* This class could not be used directly. |
* |
* From the OGC Candidate Implementation Specification: |
* "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 specification defines only one subclass of Curve, |
* LineString, which uses a linear interpolation between Points." |
