[vtkusers] ReleaseDataFlagOn question

[Naveen Kumar Polapally]

I am reposting this i have not received any help, can some form kitware 
reply to this question.



I have graphics pipeline shown below.

Reader->isosurfaceExtraction->PolyDataFilter->PolyDataFilter->etc

I am trying to understand ReleaseDataFlag Option.With ReleaseDataFlagOn Only 
the Reader seems to release the data,
while the isosurfaceExtraction and polydatafilters don't seem to realese the 
data at all.
Did any one try to observe this.

Can some one reply to this question.

Thank you,
