Hey Bastian, I think you should be able to just use the Get() method to pull out that information key. When I want to find current time step information on some pipeline data (with a programmable filter), which has information that looks like this:
vtkInformation (0x11dd723d0) Debug: Off Modified Time: 70754 Reference Count: 2 Registered Events: (none) DATA_NUMBER_OF_GHOST_LEVELS: 0 DATA_TIME_STEPS: 0 DATA_PIECE_NUMBER: 0 DATA_EXTENT_TYPE: 0 DATA_NUMBER_OF_PIECES: 1 I can do it with these commands: pdi = self.GetInputDataObject(0,0) current_time = pdi.GetInformation().Get(pdi.DATA_TIME_STEPS(),0) So you might be able to just put NAME() in where I put DATA_TIME_STEPS(). Talk to you later, -Eric ------------------------------------------------------ Eric E Monson Duke Visualization Technology Group On May 31, 2010, at 1:23 PM, [email protected] wrote: > Thanks Utkarsh, > > the required information is in MetaData: > > print iter.GetCurrentMetaData() > > vtkInformation (0x3808f00) > Debug: Off > Modified Time: 269417 > Reference Count: 2 > Registered Events: (none) > DONT_PRUNE: 1 > NAME: my_given_name > > Now I want to work with the NAME-Attribute (my_given_name) but I don't know > how to get this into a variable?
