public final Class<SerializationT> getSerializationClass() {
    return serializationClass;
  }
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 KeyParser},
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.
