 Checking for Roles inside a Voter
 ---------------------------------
 
-.. versionadded:: 2.8
-    The ability to inject the ``AccessDecisionManager`` is new in 2.8: it caused
-    a CircularReferenceException before. In earlier versions, you must inject the
-    ``service_container`` itself and fetch out the ``security.authorization_checker``
-    to use ``isGranted()``.
-
 What if you want to call ``isGranted()`` from *inside* your voter - e.g. you want
-to see if the current user has ``ROLE_SUPER_ADMIN``. That's possible by injecting
-the :class:`Symfony\\Component\\Security\\Core\\Authorization\\AccessDecisionManager`
-into your voter. You can use this to, for example, *always* allow access to a user
-with ``ROLE_SUPER_ADMIN``::
-
-    // src/AppBundle/Security/PostVoter.php
-
-    // ...
-    use Symfony\Component\Security\Core\Authorization\AccessDecisionManagerInterface;
-
-    class PostVoter extends Voter
-    {
-        // ...
-
-        private $decisionManager;
-
-        public function __construct(AccessDecisionManagerInterface $decisionManager)
-        {
-            $this->decisionManager = $decisionManager;
-        }
-
-        protected function voteOnAttribute($attribute, $subject, TokenInterface $token)
-        {
-            // ...
-
-            // ROLE_SUPER_ADMIN can do anything! The power!
-            if ($this->decisionManager->decide($token, array('ROLE_SUPER_ADMIN'))) {
-                return true;
-            }
-
-            // ... all the normal voter logic

-That's it! Calling ``decide()`` on the ``AccessDecisionManager`` is essentially
-the same as calling ``isGranted()`` from a controller or other places 
-(it's just a little lower-level, which is necessary for a voter).
-
-.. note::
-
-    The ``security.access.decision_manager`` is private. This means you can't access
-    it directly from a controller: you can only inject it into other services. That's
-    ok: use ``security.authorization_checker`` instead in all cases except for voters.
+to see if the current user has ``ROLE_SUPER_ADMIN``. The ``isGranted()`` method
+is provided by the ``security.authorization_checker`` service via the
+:class:`Symfony\\Component\\Security\\Core\\Authorization\\AccessDecisionManager`
+class. However, you can't inject that service because it causes a
+``CircularReferenceException``.
+
+The solution is to inject the ``service_container`` service and use it to get
+the ``security.authorization_checker`` service and call to the ``isGranted()``
+method.
