1. 11.x core/modules/field_ui/src/Access/FieldReuseAccessCheck.php \Drupal\field_ui\Access\FieldReuseAccessCheck::access()

Checks access to the reuse existing fields form.

Parameters

\Symfony\Component\Routing\Route $route: The route to check against.

\Drupal\Core\Routing\RouteMatchInterface $route_match: The parametrized route.

\Drupal\Core\Session\AccountInterface $account: The currently logged in account.

string|null $bundle: (optional) The bundle. Different entity types can have different names for their bundle key, so if not specified on the route via a {bundle} parameter, the access checker determines the appropriate key name, and gets the value from the corresponding request attribute. For example, for nodes, the bundle key is "node_type", so the value would be available via the {node_type} parameter rather than a {bundle} parameter.

Return value

\Drupal\Core\Access\AccessResultInterface The access result.
