    • dataReceived

      boolean dataReceived(DataSeries data)
      Called on the calling thread after each page of data has been appended to the series. The same cumulative DataSeries object is passed on every call and keeps growing between calls, so implementations that retain it across threads must take a snapshot (via the DataSeries copy constructor).
      Parameters:
      data - cumulative data received so far
      Returns:
      true to continue loading, false to abort loading
