public void verifyDeterministic() throws Coder.NonDeterministicException
Coder.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.
Unless overridden, does not throw. An AtomicCoder
is presumed to be deterministic

NonDeterministicException
- always. A TableRow
can hold arbitrary Object
instances, which makes the encoding non-deterministic.Coder.NonDeterministicException
