BufferingTermFreqIteratorWrapper
public BufferingTermFreqIteratorWrapper(TermFreqIterator source)
throws IOException
- Throws:
IOException
weight
public long weight()
- Specified by:
weight in interface TermFreqIterator
next
public BytesRef next()
throws IOException
- Description copied from interface:
BytesRefIterator
- Increments the iteration to the next
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.
- Specified by:
next in interface BytesRefIterator
- Returns:
- the next
BytesRef in the iterator or null if
the end of the iterator is reached.
- Throws:
IOException
getComparator
public Comparator<BytesRef> getComparator()
- Description copied from interface:
BytesRefIterator
- Return the
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.
- Specified by:
getComparator in interface BytesRefIterator
