### 7.1 Batch Directory Operations
```java
public class BatchDirectoryOperations {
    private final DirectoryLeaseManager leaseManager;
    
    public List<SmbFile> batchExists(List<String> paths) {
        // Group paths by parent directory
        Map<String, List<String>> pathsByParent = paths.stream()
            .collect(Collectors.groupingBy(this::getParentPath));
        
        List<SmbFile> results = new ArrayList<>();

    * You can also add [`Security` dependencies with `scopes`](../advanced/security/oauth2-scopes.md).

/// tip

Having `dependencies` in the `APIRouter` can be used, for example, to require authentication for a whole group of *path operations*. Even if the dependencies are not added individually to each one of them.

### Fonctions de chemin d'accès { #path-operation-functions }

Quand vous déclarez une *fonction de chemin d'accès* avec un `def` normal et non `async def`, elle est exécutée dans un groupe de threads (threadpool) externe qui est ensuite attendu, plutôt que d'être appelée directement (car cela bloquerait le serveur).

		RedirectURL:  pro.RedirectURL,

		// Discovery returns the OAuth2 endpoints.
		Endpoint: provider.Endpoint(),

		// "openid" is a required scope for OpenID Connect flows.
		Scopes: []string{oidc.ScopeOpenID, "groups"},
	}

	state := fmt.Sprintf("x%dx", time.Now().Unix())
	authCodeURL := oauth2Config.AuthCodeURL(state)
	// fmt.Printf("authcodeurl: %s\n", authCodeURL)

	var lastReq *http.Request

/// tip | Astuce

Avoir des `dependencies` dans le `APIRouter` peut servir, par exemple, à exiger une authentification pour tout un groupe de *chemins d'accès*. Même si les dépendances ne sont pas ajoutées individuellement à chacun d'eux.
