This could be especially useful during testing, as it's very easy to override a dependency with your own custom settings.

### The config file { #the-config-file }

Coming from the previous example, your `config.py` file could look like:

{* ../../docs_src/settings/app02_an_py310/config.py hl[10] *}

Notice that now we don't create a default instance `settings = Settings()`.

				l.lockMap[name] = *lri
			}
			delete(l.lockUID, formatUUID(args.UID, entry.idx))
			return true
		}
	}

	// None found return false, perhaps entry removed in previous run.
	return false
}

func (l *localLocker) RLock(ctx context.Context, args dsync.LockArgs) (reply bool, err error) {
	if len(args.Resources) != 1 {

    @Override
    public ReferenceEntry<K, V> getPreviousInAccessQueue() {
      return previousAccess;
    }

    @Override
    public void setPreviousInAccessQueue(ReferenceEntry<K, V> previous) {
      this.previousAccess = previous;
    }

    private long writeTime = Long.MAX_VALUE;

    @Override
    public long getWriteTime() {
      return writeTime;
    }

    @Override

    @Override
    public ReferenceEntry<K, V> getPreviousInAccessQueue() {
      return previousAccess;
    }

    @Override
    public void setPreviousInAccessQueue(ReferenceEntry<K, V> previous) {
      this.previousAccess = previous;
    }

    private long writeTime = Long.MAX_VALUE;

    @Override
    public long getWriteTime() {
      return writeTime;
    }

    @Override

To configure this bucket notification, we need the ARN printed by MinIO in the previous step. Additional information about ARN is available [here](http://docs.aws.amazon.com/general/latest/gr/aws-arns-and-namespaces.html).

		// GNU tar v1.27.1 applies global headers to subsequent records,
		// but does not do the following properly:
		//	* It does not treat an empty record as deletion.
		//	* It does not use subsequent global headers to update previous ones.
		//
		//	$ gnutar -tvf pax-global-records.tar
		//	---------- 0/0               0 2017-07-13 19:40 global1

# 依存関係としてのクラス { #classes-as-dependencies }

**依存性注入** システムを深く掘り下げる前に、先ほどの例をアップグレードしてみましょう。

## 前の例の`dict` { #a-dict-from-the-previous-example }

前の例では、依存関係（"dependable"）から`dict`を返していました:

{* ../../docs_src/dependencies/tutorial001_an_py310.py hl[9] *}

しかし、*path operation関数*のパラメータ`commons`に`dict`が含まれています。

また、エディタは`dict`のキーと値の型を知ることができないため、多くのサポート（補完のような）を提供することができません。

もっとうまくやれるはずです...。
