[vtkusers] What is vtkCxxSetObjectMacro

[Wenlong Wang]

Dear all,

I'm trying to set a vtkPoints to my polydata. Here is what I do.

polydata->SetPoints(points);

The compiler returns a access vialation and redirect me to line 32 in
vtkPointSet.cxx. The source code is vtkCxxSetObjectMacro(vtkPointSet,
Points, vtkPoints);

I haven't find any reference about it online. Can anyone tell me what is
this and how it works?

Thank you very much.

Best Regards
Wenlong
