CoderCoder for a parameterized type, returns the
list of Coders being used for each of the parameters in the same order they appear
within the parameterized type's type signature. If this cannot be done, or this
Coder does not encode/decode a parameterized type, returns the empty list.getCoderArguments in class Coder<ShardedKey<KeyT>>public void encode(ShardedKey<KeyT> key, java.io.OutputStream outStream) throws java.io.IOException

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