Hi, I want to modify a vtkInformation object (specifically one within a vtkInformation vector) to point to a new data set.
The use case is I have a derived class for which, in its RequestData method, I want to do some preprocessing on the input, then send the preprocessed input to the superclass via the superclass' RequestData method, then post process the output within the derived class. I don't want to modify the original input so I work with an (in my use case much smaller) subset of it, but the problem is then passing it on to the superclass for processing. Right now I do: inputVector[0]->GetInformationObject(0)->Set( vtkDataObject::DATA_OBJECT(),newDataSet). Before my call to the super's RequestData method, but the superclass seems not to operate on the newDataSet, nor on the original data set, so I think I'm inadvertently pummeling something, probably using the wrong vtkInformationDataObjectKey. However I'm not sure how to divine the correct one. Any help would be appreciated.
