T
- the type of the values being transcodedpublic abstract class AtomicCoder<T> extends StructuredCoder<T>
Coder
that has no component Coders
or other configuration.
Unless the behavior is overridden, atomic coders are presumed to be deterministic.
All atomic coders of the same class are considered to be equal to each other. As a result, an
AtomicCoder
should have no associated configuration (instance variables, etc).

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

type signature. If this cannot be done, or this Coder
does not encode/decode a
