be encoded next to each other on the output stream, each coder should encode information to
know how many bytes to read when decoding. A common approach is to prefix the encoding with the

Coder
Coder.NonDeterministicException
if the coding is not deterministic.
In order for a Coder
to be considered deterministic, the following must be true:
Object.equals()

, if supported) have the same encoding.
Coder
always produces a canonical encoding, which is the same for an instance
of an object even if produced on different computers at different times.
