[JAVA3D] currentKnotIndex

[David Huang]

Forgive me if this is a double post, but I don't think my original post got through. Hi, Can someone explain why I can not access currentKnotIndex from an instance of a PositionPathInterpolator class. From what I understand from reading the API document, PositionPathInterpolator inherited from PathInterpolator, which have a protected field currentKnotIndex. Thus PositionPathInterpolator should have access to currentKnotIndex, correct? So, why can I not do this: PositionPathInterpolator x = new PositionPathInterpolator(...); ... int y = x.currentKnotIndex The compiler gives this error message: 421: currentKnotIndex has protected access in javax.media.j3d.PathInterpolator Please someone clearify, I posted this in the java.programmer newsgroup and no one seems to know. Thanks
