public final Bytes getObjectIdentifier() {
    return objectIdentifier;
  }
Returns the {@code objectIdentifier} for this serialization.

<p>The object identifier is a unique identifier per registry for this object (in the standard
proto serialization, it is the typeUrl). In other words, when registering a {@code
ParametersParser}, the registry will invoke this to get the handled object identifier. In order
to parse an object of type {@code SerializationT}, the registry will then obtain the {@code
objectIdentifier} of this serialization object, and call the parser corresponding to this
object.
