question: public static DLSN deserializeBytes ( byte [ ] data ) { ByteBuffer bb = ByteBuffer . wrap ( data ) ; byte version = bb . get ( ) ; if ( VERSION0 == version ) { if ( VERSION0_LEN != data . length ) { throw new IllegalArgumentException ( "Invalid version zero DLSN " + Hex . encodeHexString ( data ) ) ; } } else if ( VERSION1 == version ) { if ( VERSION1_LEN != data . length ) { throw new IllegalArgumentException ( "Invalid version one DLSN " + Hex . encodeHexString ( data ) ) ; } } else { throw new IllegalArgumentException ( "Invalid DLSN : version = " + version + ", " + Hex . encodeHexString ( data ) ) ; } return new DLSN ( bb . getLong ( ) , bb . getLong ( ) , bb . getLong ( ) ) ; }
target:  Deserialize the DLSN from bytes array.
