iterator. |

Increments the iteration to the next

BytesRef next() throws IOException
BytesRef
in the iterator.
Returns the resulting BytesRef
or null
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
are undefined.BytesRef

Comparator<BytesRef> getComparator()
BytesRef
Comparator used to sort terms provided by the
iterator. This may return null if there are no items or the iterator is not
sorted. Callers may invoke this method many times, so it's best to cache a
single instance & reuse it.Copyright © 2000-2018 Apache Software Foundation. All Rights Reserved.
