Method Detail

weight
public long weight()
Description copied from interface:InputIterator
A term's weight, higher numbers mean better suggestions.- Specified by:
weight
in interfaceInputIterator
- Overrides:
weight
in classBufferedInputIterator
-
next
public BytesRef next() throws java.io.IOException
Description copied from interface:BytesRefIterator
Increments the iteration to the nextBytesRef
in the iterator. Returns the resultingBytesRef
ornull
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 interfaceBytesRefIterator
- Overrides:
next
in classBufferedInputIterator
- Returns:
- the next
BytesRef
in the iterator ornull
if the end of the iterator is reached. - Throws:
java.io.IOException
- If there is a low-level I/O error.
-
payload
public BytesRef payload()
Description copied from interface:InputIterator
An arbitrary byte[] to record per suggestion. SeeLookup.LookupResult.payload
to retrieve the payload for each suggestion.- Specified by:
payload
in interfaceInputIterator
- Overrides:
payload
in classBufferedInputIterator
