copy

RandomAccessQuantizedByteVectorValues 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 vector returned.

Specified by:

copy in interface RandomAccessVectorValues

Specified by:

copy in interface RandomAccessVectorValues.Bytes

Throws:

IOException
