[Paraview] vtkDataSet algorithm that takes composite data set as input

[David E DeMarle]

Try something like this.
In this case the mapper takes in either type, which you may or may not want.

//----------------------------------------------------------------------------
int vtkCompositePolyDataMapper2::FillInputPortInformation(
  int vtkNotUsed(port), vtkInformation* info)
{
  info->Set(vtkAlgorithm::INPUT_REQUIRED_DATA_TYPE(), "vtkPolyData");
  info->Append(vtkAlgorithm::INPUT_REQUIRED_DATA_TYPE(),
"vtkCompositeDataSet");
  return 1;
}
