write vtkInformation


Is there a way to serialize extra keys from vtkInformation of an object ?
I mean, i create an extra object key attached (instance of a class MyInfoObj which derived from vtkObjectBase) to a vtkPolyData object, I don’t know if it’s possible to write extra information tags (inn the xml) using the vtkXMLPolyDataWriter ? Do I need to override a specific method in my object class MyInfoObj to manage the extra xml writings ? Same for the desarialization using vtkXMLPolyDataReader.

Best regards.
