Method Details

size

public int size()

Description copied from interface: RandomAccessVectorValues

Return the number of vector values

Specified by:

size in interface RandomAccessVectorValues

dimension

public int dimension()

Description copied from interface: RandomAccessVectorValues

Return the dimension of the returned vector values

Specified by:

dimension in interface RandomAccessVectorValues

vectorValue

public float[] vectorValue(int targetOrd)
                    throws IOException

Description copied from interface: RandomAccessVectorValues

Return the vector value indexed at the given ordinal. The provided floating point array may be shared and overwritten by subsequent calls to this method and RandomAccessVectorValues.binaryValue(int).

Specified by:

vectorValue in interface RandomAccessVectorValues

Parameters:

targetOrd - a valid ordinal, ≥ 0 and < RandomAccessVectorValues.size().

Throws:

IOException

binaryValue

public BytesRef binaryValue(int targetOrd)
                     throws IOException

Description copied from interface: RandomAccessVectorValues

Return the vector indexed at the given ordinal value as an array of bytes in a BytesRef; these are the bytes corresponding to the float array. The provided bytes may be shared and overwritten by subsequent calls to this method and RandomAccessVectorValues.vectorValue(int).

Specified by:

binaryValue in interface RandomAccessVectorValues

Parameters:

targetOrd - a valid ordinal, ≥ 0 and < RandomAccessVectorValues.size().

Throws:

IOException

copy

public RandomAccessVectorValues copy()
                              throws IOException

Description copied from interface: RandomAccessVectorValues

Creates a new copy of this RandomAccessVectorValues. This is helpful when you need to access different values at once, to avoid overwriting the underlying float vector returned by RandomAccessVectorValues.vectorValue(int).

Specified by:

copy in interface RandomAccessVectorValues

Throws:

IOException
