code: def _setStatePointers(self):
      
      if not self.allocateStatesInCPP:
        self.cells4.setStatePointers(
            self.infActiveState["t"], self.infActiveState["t-1"],
            self.infPredictedState["t"], self.infPredictedState["t-1"],
            self.colConfidence["t"], self.colConfidence["t-1"],
            self.cellConfidence["t"], self.cellConfidence["t-1"])
docs: If we are having CPP use numpy-allocated buffers, set these buffer
      pointers. This is a relatively fast operation and, for safety, should be
      done before every call to the cells4 compute methods.  This protects us
      in situations where code can cause Python or numpy to create copies.
