[vtkusers] vtkDataObject::SeriesLength

[Charles Law]

Gerald,

SeriesLength was initially added to support readers that generate a series 
of data sets (Possibly to support time steps).  It was a temporary 
experiment that no longer exists in the nightly release of VTK.  It must 
have accidentally been included in the 3.1.2 release.  There was no intent 
to support multiple time steps in a data object at one time.  Piece and 
NumberOfPieces could be used instead.  You would have to modify a reader to 
select a file based on a piece.

Charles.
