public function RequestQueryArgumentResolver::resolve in Organic groups 8

Resolves groups within the plugin's domain.

Parameters

\Drupal\og\OgResolvedGroupCollectionInterface $collection: A collection of groups that were resolved by previous plugins. If the plugin discovers new groups, it may add these to this collection.
