Ok it works but there is a mistake in this page:
http://paraview.org/OnlineHelpCurrent/LegacyVTKFileReader.html
since the name of the class is mentionned as "LegacyVTKFileReader"

Suppose I have a filter that can process only a limited set of file types: I
would like to test the actual type of a file before applying the filter, so I
try this:
data = reader.GetDataInformation()
data.IsA("vtkImageData")
which actually returns always 0, so I probably did not use the right method.
