MergedByteVectorValues

private MergedByteVectorValues(List<KnnVectorsWriter.ByteVectorValuesSub> subs,
 MergeState mergeState)
                        throws IOException

Throws:

IOException

Method Details

vectorValue

public byte[] vectorValue(int ord)
                   throws IOException

Description copied from class: ByteVectorValues

Return the vector value for the given vector ordinal which must be in [0, size() - 1], otherwise IndexOutOfBoundsException is thrown. The returned array may be shared across calls.

Specified by:

vectorValue in class ByteVectorValues

Returns:

the vector value

Throws:

IOException

iterator

public KnnVectorValues.DocIndexIterator iterator()

Description copied from class: KnnVectorValues

Create an iterator for this instance.

Overrides:

iterator in class KnnVectorValues

size

public int size()

Description copied from class: KnnVectorValues

Return the number of vectors for this field.

Specified by:

size in class KnnVectorValues

Returns:

the number of vectors returned by this iterator

dimension

public int dimension()

Description copied from class: KnnVectorValues

Return the dimension of the vectors

Specified by:

dimension 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

scorer

public VectorScorer scorer(byte[] target)

Description copied from class: ByteVectorValues

Return a VectorScorer for the given query vector.

Overrides:

scorer in class ByteVectorValues

Parameters:

target - the query vector

Returns:

a VectorScorer instance or null

copy

public ByteVectorValues copy()

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
