+ * Interface for AccessibleInterface objects that have an access dependency.
+ *
+ * Objects should implement this interface when their access depends on access
+ * to another object that implements \Drupal\Core\Access\AccessibleInterface.
+ * This interface simply provides the getter method for the access
+ * dependency object. Objects that implement this interface are responsible for
+ * checking access of the access dependency because the dependency may not take
+ * effect in all cases. For instance an entity may only need the access
+ * dependency set when it is embedded within another entity and its access
+ * should be dependent on access to the entity in which it is embedded.
+ *
+ * To check the access to the dependency the object implementing this interface
+ * can use code like this:
+ * @code
+ * $accessible->getAccessDependency()->access($op, $account, TRUE);
+ * @endcode
+ *
+ * @internal
