[Paraview-developers] Removal of ExecuteData(...)

[Schlottke, Michael]

Hi Berk,

Thank you for your answer. What do you mean by “minor changes” (other than that I somehow have to obtain the correct output pointer)? And do I really need to pass data to Execute()? As far as I can tell, the particular filter I’m looking at does nothing in Execute() (really a no-op), so it seems like a good candidate to be removed completely.

Hi Michael,

You will need some minor changes but yes you can move that to RequestData(). You will have to pass the input and output to Execute() somehow.

Best,

Hi again,

I am trying to follow the VTK guide (http://www.vtk.org/Wiki/VTK/VTK_6_Migration/Removal_of_Execute) on migrating a set of ParaView plugins from VTK 5 to VTK 6.

Just to be sure, what would be the correct way to replace the following implementation:

/////////////////////////////////////////////////////////////////////////
void vtkMyAlgorithmSubclass::ExecuteData(vtkDataObject *output)
{
  if (output && this->UpdateExtentIsEmpty(output))
    {
    output->Initialize();
    return;
    }

  this->Execute();
}
/////////////////////////////////////////////////////////////////////////

Can I just move this whole code into RequestData (and use the vtkDataObject* output as a downcast from my output info object)? Is the call to Execute() still needed in this case?

Thanks!

Michael
