OffHeapByteVectorValues

public static class OffHeapByteVectorValues.DenseOffHeapVectorValues
extends OffHeapByteVectorValues

Dense vector values that are stored off-heap. This is the most common case when every doc has a vector.

Method Details

copy

public OffHeapByteVectorValues.DenseOffHeapVectorValues copy()
                                                      throws IOException

Description copied from class: KnnVectorValues

Creates a new copy of this KnnVectorValues. This is helpful when you need to access different values at once, to avoid overwriting the underlying vector returned.

Specified by:

copy in class ByteVectorValues

Throws:

IOException

iterator

public KnnVectorValues.DocIndexIterator iterator()

Description copied from class: KnnVectorValues

Create an iterator for this instance.

Overrides:

iterator in class KnnVectorValues

getAcceptOrds

public Bits getAcceptOrds(Bits acceptDocs)

Description copied from class: KnnVectorValues

Returns a Bits accepting docs accepted by the argument and having a vector value

Overrides:

getAcceptOrds in class KnnVectorValues

scorer

public VectorScorer scorer(byte[] query)
                    throws IOException

Description copied from class: ByteVectorValues

Return a VectorScorer for the given query vector.

Overrides:

scorer in class ByteVectorValues

Parameters:

query - the query vector

Returns:

a VectorScorer instance or null

Throws:

IOException
