- // This encoding, called UNSIGNED5, is taken from J2SE Pack200.
- // It assumes that most values have lots of leading zeroes.
- // Very small values, in the range [0..191], code in one byte.
- // Any 32-bit value (including negatives) can be coded, in
- // up to five bytes.  The grammar is:
- //    low_byte  = [0..191]
- //    high_byte = [192..255]
- //    any_byte  = low_byte | high_byte
- //    coding = low_byte
- //           | high_byte low_byte
- //           | high_byte high_byte low_byte
- //           | high_byte high_byte high_byte low_byte
- //           | high_byte high_byte high_byte high_byte any_byte
- // Each high_byte contributes six bits of payload.
- // The encoding is one-to-one (except for integer overflow)
- // and easy to parse and unparse.
