-// .NAME vtkPVUpdateSuppressor - prevents propagation of update
-// .SECTION Description
-// vtkPVUpdateSuppressor now uses the vtkProcessModule singleton to set up the
-// default values for UpdateNumberOfPieces and UpdatePiece, so we no longer have
-// to set the default values (in most cases).
-// .SECTION See Also
-// vtkPVCacheKeeper vtkUpdateSuppressorPipeline
