3. 10 core/lib/Drupal/Core/Routing/Router.php \Drupal\Core\Routing\Router::applyFitOrder()

Reapplies the fit order to a RouteCollection object.

Route filters can reorder route collections. For example, routes with an explicit _format requirement will be preferred. This can result in a less fit route being used. For example, as a result of filtering /user/% comes before /user/login. In order to not break this fundamental property of routes, we need to reapply the fit order. We also need to ensure that order within each group of the same fit is preserved.

Parameters

\Symfony\Component\Routing\RouteCollection $collection: The route collection.

Return value

\Symfony\Component\Routing\RouteCollection The reordered route collection.
