Method Detail

getBitPackingWriter

public static BitPacking.BitPackingWriter getBitPackingWriter(int bitLength,
                                              OutputStream out)

Parameters:

bitLength - the width in bits of the integers to write

out - the stream to write the bytes to

Returns:

the correct implementation for the width

                                                 long valueCount)

Parameters:

bitLength - the width in bits of the integers to read

inthe - stream to read the bytes from

Returns:

the correct implementation for the width
