Expert: Restore a PackedInts.Reader from a stream without reading metadata at the beginning of the stream. This method is useful to restore data from streams which have been created using PackedInts.getWriterNoHeader(DataOutput, PackedInts.Format, int, int, int).

Parameters:

in - the stream to read data from, positioned at the beginning of the packed values

format - the format used to serialize

version - the version used to serialize the data

valueCount - how many values the stream holds

bitsPerValue - the number of bits per value

Returns:

a Reader

Throws:

IOException - If there is a low-level I/O error
