Method Details

copy

public OffHeapFloatVectorValues.SparseOffHeapVectorValues 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 FloatVectorValues

Throws:

IOException

iterator

public KnnVectorValues.DocIndexIterator iterator()

Description copied from class: KnnVectorValues

Create an iterator for this instance.

Overrides:

iterator in class KnnVectorValues

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 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(float[] query)
                    throws IOException

Description copied from class: FloatVectorValues

Return a VectorScorer for the given query vector and the current FloatVectorValues.

Overrides:

scorer in class FloatVectorValues

Parameters:

query - the query vector

Returns:

a VectorScorer instance or null

Throws:

IOException
