[vtkusers] ReleaseDataFlagOn question

[Naveen Kumar Polapally]

hi,

I have graphics pipeline shown below.

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

I am trying to under stand 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,

naveen.
