iterator
Description copied from class:KnnVectorValues
Create an iterator for this instance.- Overrides:
iterator
in classKnnVectorValues
-
copy
Description copied from class:KnnVectorValues
Creates a new copy of thisKnnVectorValues
. This is helpful when you need to access different values at once, to avoid overwriting the underlying vector returned.- Overrides:
copy
in classQuantizedByteVectorValues
- Throws:
IOException
-
ordToDoc
public int ordToDoc(int ord) Description copied from class:KnnVectorValues
Return the docid of the document indexed with the given vector ordinal. This default implementation returns the argument and is appropriate for dense values implementations where every doc has a single value.- Overrides:
ordToDoc
in classKnnVectorValues
-
getAcceptOrds
Description copied from class:KnnVectorValues
Returns a Bits accepting docs accepted by the argument and having a vector value- Overrides:
getAcceptOrds
in classKnnVectorValues
-
scorer
Description copied from class:QuantizedByteVectorValues
Return aVectorScorer
for the given query vector.- Overrides:
scorer
in classQuantizedByteVectorValues
- Parameters:
target
- the query vector- Returns:
- a
VectorScorer
instance or null - Throws:
IOException
