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
-
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
- 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
-
hasPayloads
public boolean hasPayloads()
Description copied from interface:InputIterator
Returns true if the iterator has payloads- Specified by:
hasPayloads
in interfaceInputIterator
-
readWeight
private void readWeight(java.lang.String weight)
-
contexts
public java.util.Set<BytesRef> contexts()
Description copied from interface:InputIterator
A term's contexts context can be used to filter suggestions. May return null, if suggest entries do not have any context- Specified by:
contexts
in interfaceInputIterator
-
hasContexts
public boolean hasContexts()
Description copied from interface:InputIterator
Returns true if the iterator has contexts- Specified by:
hasContexts
in interfaceInputIterator
