Method Details

iterator

public SlowCompositeCodecReaderWrapper.MergedDocIterator<ByteVectorValues> iterator()

Description copied from class: KnnVectorValues

Create an iterator for this instance.

Overrides:

iterator in class KnnVectorValues

dimension

public int dimension()

Description copied from class: KnnVectorValues

Return the dimension of the vectors

Specified by:

dimension 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

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

copy

public ByteVectorValues 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
