public class SortedInputIterator extends Object implements InputIterator
InputIterator.InputIteratorWrapper
EMPTY
Constructor and Description |
---|
SortedInputIterator(Directory tempDir,
String tempFileNamePrefix,
InputIterator source)
Creates a new sorted wrapper, using natural order
for sorting.
|
SortedInputIterator(Directory tempDir,
String tempFileNamePrefix,
InputIterator source,
Comparator<BytesRef> comparator)
Creates a new sorted wrapper, sorting by BytesRef
(ascending) then cost (ascending).

Modifier and Type | Method and Description |
---|---|
Set<BytesRef> |
contexts()
A term's contexts context can be used to filter suggestions.
|
protected long |
decode(BytesRef scratch,
ByteArrayDataInput tmpInput)
decodes the weight at the current position
|
protected Set<BytesRef> |
decodeContexts(BytesRef scratch,
ByteArrayDataInput tmpInput)
decodes the contexts at the current position
|
protected BytesRef |
decodePayload(BytesRef scratch,
ByteArrayDataInput tmpInput)
decodes the payload at the current position
|
protected void |
encode(OfflineSorter.ByteSequencesWriter writer,
ByteArrayDataOutput output,
byte[] buffer,
BytesRef spare,
BytesRef payload,
Set<BytesRef> contexts,
long weight)
encodes an entry (bytes+(contexts)+(payload)+weight) to the provided writer
|
boolean |
hasContexts()
Returns true if the iterator has contexts
|
boolean |
hasPayloads()
Returns true if the iterator has payloads
|
BytesRef |
next() |
BytesRef |
payload()
An arbitrary byte[] to record per suggestion.
|
long |
weight()
A term's weight, higher numbers mean better suggestions.
