      Specified by:
        `close` in interface `AutoCloseable`
      Throws:
        `IOException`

    - #### reinit

          public void reinit(boolean eraseIndex)
                      throws Exception

      Returns:
        Returns the points.

    - #### getDirectory

          public Directory getDirectory()

      Returns:
        Returns the directory.

          public void setTaxonomyReader(TaxonomyReader taxoReader)
                                 throws IOException

      Set the taxonomy reader. Takes ownership of that taxonomy reader, that is, internally performs taxoReader.incRef() (If caller no longer needs that reader it should decRef()/close() it after calling this method, otherwise, the reader will remain open).
