  * value. Applications are encouraged to lock the index, then invoke {@link #read()} to ensure the
  * in-memory data is current, prior to updating the in-memory entries.
  *
  * <p>Once written the lock is closed and must be either committed with {@link #commit()} or
  * rolled back with {@link #unlock()}.
  *
  * @throws IOException the output file could not be created. The caller no longer holds the lock.
