Note that this adding curves to the result of calling this method may throw a

or IllegalArgumentException
in case the class of the curve(s) to add is not
compatible with the implementation of the composite curve. Implementations should

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.

public int getLineSegmentIntersectionCount(ILcdPoint aP1, ILcdPoint aP2)
ILcdCurve
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.
