4. 7.2 includes/flag.admin.inc \_flag_clear_cache()

Clears various caches when one or more flags are modified.

Parameters

string|array $entity_types: The entity types for the flags. May be a single value or an array.

bool $is_insert_or_delete: Whether the modified flag is being inserted (saved for the first time) or deleted. This results in a more vigorous clearing of caches. In particular, when no flags exist yet, no Field admin UI paths exist and these need to be created.

    // entity, and thus need to clear the entity info cache.
    entity_info_cache_clear();
  }

  // Clear FieldAPI's field_extra cache, so our changes to pseudofields are
  // noticed. It's rather too much effort to both a) check whether the
  // pseudofield setting has changed either way, and b) specifically clear just
  // the bundles that are (or were!!) affected, so we just clear for all bundles
  // on our entity type regardlesss.

  // The title of a flag may appear in the menu (indirectly, via our "default
  // views"), so we need to clear the menu cache. This call also clears the
  // page cache, which is desirable too because the flag labels may have
  // changed.
