If the property is a collection, the returned value will never be null. If the property has not been set, an empty collection of the appropriate type will be returned (Set, List or Map).
The property must not be null, and must be declared in the data object's type or in one of its super types.
Otherwise an IllegalArgumentException is thrown.

ILcdCurve
A set of predefined constants are defined in this interface,
which are used by the default ILcdCurve implementations
provided by LuciadLightspeed.
Custom implementations can define their own constants, and use them to interpret the interpolation of the curve.
getInterpolation in interface ILcdCurvepublic int getLineSegmentIntersectionCount(ILcdPoint aP1, ILcdPoint aP2)
ILcdCurveThis 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.
