 * to other contained types; for example, bean serializers use this
 * to eagerly find serializers for contained field types.
 *<p>
 * Note that in cases where serializer needs both contextualization and
 * resolution -- that is, implements both this interface and {@link ContextualSerializer}
 * -- resolution via this interface occurs first, and contextual
 * resolution (using {@link ContextualSerializer}) later on.
