10 * Returns the local ID of an entity referenced by serialized data.
11 *
12 * Drupal entities are loaded by and internally referenced by a local ID.
13 * Because different websites can use the same local ID to refer to different
14 * entities (e.g., node "1" can be a different node on foo.com and bar.com, or
15 * on example.com and staging.example.com), it is generally unsuitable for use
16 * in hypermedia data exchanges. Instead, UUIDs, URIs, or other globally
17 * unique IDs are preferred.
18 *
19 * This function takes a $data array representing partially deserialized data
20 * for an entity reference, and resolves it to a local entity ID. For example,
21 * depending on the data specification being used, $data might contain a
22 * 'uuid' key, a 'uri' key, a 'href' key, or some other data identifying the
23 * entity, and it is up to the implementor of this interface to resolve that
24 * appropriately for the specification being used.
25 *
26 * @param \Symfony\Component\Serializer\Normalizer\NormalizerInterface $normalizer
27 * The Normalizer which is handling the data.
28 * @param array $data
29 * The data passed into the calling Normalizer.
30 * @param string $entity_type
31 * The type of entity being resolved; e.g., 'node' or 'user'.
32 *
33 * @return string|null
34 * Returns the local entity ID, if found. Otherwise, returns NULL.
