next()
Increments the iteration to the next
BytesRef in the iterator. |
BytesRef |
payload()
An arbitrary byte[] to record per suggestion.

if the end of
the iterator is reached. The returned BytesRef may be re-used across calls
to next. After this method returns null, do not call it again: the results
