public class TLcdXYZFloatLine extends ALcd3DEditableShape implements ILcd3DEditablePolyline, ILcdCurve
ILcd3DEditablePolyline
that always has two points, in the cartesian space.
This class is thread-hostile, even for read-only access, since point instances are being reused from an internal pool.

This information can be used to perform containment calculations, if this curve is closed or if this curve is part of a composite closed curve. By determining the number of intersections between this curve and a line segment starting from a given point in a fixed direction, one can determine whether a point is located within the closed curve by using the even-odd rule.
