scorer
RandomVectorScorer scorer(int ord) throws IOException
This creates aRandomVectorScorerfor scoring random nodes in batches against the given ordinal.- Parameters:
ord- the ordinal of the node to compare- Returns:
- a new
RandomVectorScorer - Throws:
IOException
-
copy
RandomVectorScorerSupplier copy() throws IOException
Make a copy of the supplier, which will copy the underlying vectorValues so the copy is safe to be used in other threads.- Throws:
IOException
-
createFloats
static RandomVectorScorerSupplier createFloats(RandomAccessVectorValues<float[]> vectors, VectorSimilarityFunction similarityFunction) throws IOException
Creates aRandomVectorScorerSupplierto compare float vectors. The vectorValues passed in will be copied and the original copy will not be used.- Parameters:
vectors- the underlying storage for vectorssimilarityFunction- the similarity function to score vectors- Throws:
IOException
-
createBytes
static RandomVectorScorerSupplier createBytes(RandomAccessVectorValues<byte[]> vectors, VectorSimilarityFunction similarityFunction) throws IOException
Creates aRandomVectorScorerSupplierto compare byte vectors. The vectorValues passed in will be copied and the original copy will not be used.- Parameters:
vectors- the underlying storage for vectorssimilarityFunction- the similarity function to score vectors- Throws:
IOException
