/**
 * Parameter converter for upcasting entity IDs to full objects.
 *
 * This is useful in cases where the dynamic elements of the path can't be
 * auto-determined; for example, if your path refers to multiple of the same
 * type of entity ("example/{node1}/foo/{node2}") or if the path can act on any
 * entity type ("example/{entity_type}/{entity}/foo").
 *
 * In order to use it you should specify some additional options in your route:
 * @code
 * example.route:
 *   path: foo/{example}
 *   options:
 *     parameters:
 *       example:
 *         type: entity:node
 * @endcode
 *
 * If you want to have the entity type itself dynamic in the URL you can
 * specify it like the following:
 * @code
 * example.route:
 *   path: foo/{entity_type}/{example}
 *   options:
 *     parameters:
 *       example:
 *         type: entity:{entity_type}
 * @endcode
 *
 * The conversion can be limited to certain entity bundles by specifying a
 * parameter 'bundle' definition property as an array:
 * @code
 * example.route:
 *   path: foo/{example}
 *   options:
 *     parameters:
 *       example:
 *         type: entity:node
 *         bundle:
 *           - article
 *           - news
 * @endcode
 * In the above example, only node entities of types 'article' and 'news' are
 * converted. For a node of a different type, such as 'page', the route will
 * return 404 'Not found'.
 *
 * If your route needs to support pending revisions, you can specify the
 * "load_latest_revision" parameter. This will ensure that the latest revision
 * is returned, even if it is not the default one:
 * @code
 * example.route:
 *   path: foo/{example}
 *   options:
 *     parameters:
 *       example:
 *         type: entity:node
 *         load_latest_revision: TRUE
 * @endcode
 *
 * When dealing with translatable entities, the "load_latest_revision" flag will
 * make this converter load the latest revision affecting the translation
 * matching the content language for the current request. If none can be found
 * it will fall back to the latest revision. For instance, if an entity has an
 * English default revision (revision 1) and an Italian pending revision
 * (revision 2), "/foo/1" will return the former, while "/it/foo/1" will return
 * the latter.
 *
