Interface InputIterator

All Superinterfaces:
BytesRefIterator
All Known Implementing Classes:
BufferedInputIterator, DocumentDictionary.DocumentInputIterator, InputIterator.InputIteratorWrapper, SortedInputIterator, UnsortedInputIterator

public interface InputIterator
extends BytesRefIterator

Interface for enumerating term,weight,payload triples for suggester consumption; currently only AnalyzingSuggester, FuzzySuggester and AnalyzingInfixSuggester support payloads.


Nested Class Summary
static class InputIterator.InputIteratorWrapper
          Wraps a BytesRefIterator as a suggester InputIterator, with all weights set to 1 and carries no payload
 
Field Summary
static InputIterator EMPTY
          Singleton InputIterator that iterates over 0 BytesRefs.
 
Method Summary
 boolean hasPayloads()
          Returns true if the iterator has payloads
 BytesRef payload()
          An arbitrary byte[] to record per suggestion.
 long weight()
          A term's weight, higher numbers mean better suggestions.

Field Detail

EMPTY

static final InputIterator EMPTY
Singleton InputIterator that iterates over 0 BytesRefs.

Method Detail

weight

long weight()
A term's weight, higher numbers mean better suggestions.


payload

BytesRef payload()
An arbitrary byte[] to record per suggestion. See Lookup.LookupResult.payload to retrieve the payload for each suggestion.


hasPayloads

boolean hasPayloads()
Returns true if the iterator has payloads
