  "have been leaked deletes them.  The garbage collector uses the\n"
  "ReportReferences method to search the reference graph and construct a\n"
  "net reference count for each connected component.  If the net\n"
  "reference count is zero the entire set of objects is deleted.\n"
  "Deleting each component may leak other components, which are then\n"
  "collected recursively.\n\n"

  "be nullptr or refer to a fully constructed valid object.  Therefore\n"

  "vtkObjectBase* obj = this->Object;\n"
  "  this->Object = 0;\n"
