Method GetDirectReaderNoHeader
GetDirectReaderNoHeader(IndexInput, PackedInt32s.Format, Int32, Int32, Int32)
Expert: Construct a direct PackedInt32s.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 GetWriterNoHeader(DataOutput, PackedInt32s.Format, Int32, Int32, Int32).
The returned reader will have very little memory overhead, but every call to Get(Int32) is likely to perform a disk seek.
