[Paraview] Filter with variable outputs as plugin

[Joachim Pouderoux]

Unfortunately it is not possible.
You could however have a single multiblock outpout port that would contains
your meshes and set the name of each block with the name you read in your
file.
Eg:

  vtkPolyData* polyData[10];
  std::string polyDataName[10];
  for (int i = 0; i < 10; i++)
  {
    mb->SetBlock(i, polydata[i]);
    mb->GetMetaData(i)->Set(vtkCompositeDataSet::NAME(),
polyDataName[i].c_str());
  }
