[Paraview-developers] Necessity for RequestDataObject in custom reader plugin

[Schlottke, Michael]

Hi folks,

Can somebody help me understand the purpose of the RequestDataObject() for a reader plugin? I see this method pop up now and then (typically in generic examples on how to create custom sources), but most of the readers in the Plugins/ directory do not seem to  use it. Is there a simple definition I can use to decide if and how to implement it?

Regards,

Michael

P.S.: I’m working on two readers of vtkUnstructuredGridAlgorithm and vtkMultiBlockDataSetAlgorithm type.
