Chris@17:  * Interface for AccessibleInterface objects that have an access dependency.
Chris@17:  *
Chris@17:  * Objects should implement this interface when their access depends on access
Chris@17:  * to another object that implements \Drupal\Core\Access\AccessibleInterface.
Chris@17:  * This interface simply provides the getter method for the access
Chris@17:  * dependency object. Objects that implement this interface are responsible for
Chris@17:  * checking access of the access dependency because the dependency may not take
Chris@17:  * effect in all cases. For instance an entity may only need the access
Chris@17:  * dependency set when it is embedded within another entity and its access
Chris@17:  * should be dependent on access to the entity in which it is embedded.
Chris@17:  *
Chris@17:  * To check the access to the dependency the object implementing this interface
Chris@17:  * can use code like this:
Chris@17:  * @code
Chris@17:  * $accessible->getAccessDependency()->access($op, $account, TRUE);
Chris@17:  * @endcode
