You can always ask :-) It's not my class though so I have no idea what those arrays are. Feel free to dig into the code (VTK/Filters/General/vtkTemporalPathLineFilter.cxx) to figure it out and contribute updated doc. Or you may want to go to the VTK developers list. Or bug John Biddiscombe directly (the original author).
