Function GetGeometryObjects

Code/Source/PythonAPI/Geometry_PyModule.cxx:114–141

-------------------- GetGeometryObjects -------------------- Create a list of cvPolyData objects from a list of vtkPolyData objects. [TODO:DaveP] It would be good to use shared_ptr here to manage deleting cvPolyData objects but the sys_geom functions don't use them.

// functions don't use them.
//
static std::vector<cvPolyData*>
GetGeometryObjects(PyUtilApiFunction& api, PyObject* objList)
{
  std::vector<cvPolyData*> cvPolyDataList;
  auto numObjs = PyList_Size(objList);

  if (numObjs == 0) {
      api.error("The polydata list argument is empty.");
      return cvPolyDataList;
  }

  for (int i = 0; i < numObjs; i++ ) {
      auto obj = PyList_GetItem(objList, i);
      auto polydata = GetVtkPolyData(api, obj);
      if (polydata == nullptr) {
          api.error("Index " + std::to_string(i) + " of the polydata list argument is not a vtkPolyData object.");
          for (auto cvPolydata : cvPolyDataList) {
              delete cvPolydata;
          }
          cvPolyDataList.clear();
          return cvPolyDataList;

      auto cvPolydata = new cvPolyData(polydata);
      cvPolyDataList.push_back(cvPolydata);
