 * Add-on interface that {@link JsonSerializer}s can implement to get a callback
 * that can be used to create contextual instances of serializer to use for
 * handling properties of supported type. This can be useful
 * for serializers that can be configured by annotations, or should otherwise
 * have differing behavior depending on what kind of property is being serialized.
 *<p>
 * Note that in cases where serializer needs both contextualization and
 * resolution -- that is, implements both this interface and {@link ResolvableSerializer}
 * -- resolution via {@link ResolvableSerializer} occurs first, and contextual
 * resolution (via this interface) later on.
