Und alle Ideen aus dem Abschnitt über das [Hinzufügen von `dependencies` zu den *Pfadoperation-Dekoratoren*](dependencies-in-path-operation-decorators.md) gelten weiterhin, aber in diesem Fall für alle *Pfadoperationen* in der App.

Beachten Sie, dass in diesem Fall das `item`, welches vom Body genommen wird, optional ist. Da es `None` als Defaultwert hat.

herself in a long, low hall, which was lit up by a row of lamps
hanging from the roof.

  There were doors all round the hall, but they were all locked;
and when Alice had been all the way down one side and up the
other, trying every door, she walked sadly down the middle,
wondering how she was ever to get out again.

  Suddenly she came upon a little three-legged table, all made of

Der springende Punkt ist, dass eine Abhängigkeit aufrufbar („callable“) sein sollte.

Ein „**Callable**“ in Python ist etwas, das wie eine Funktion aufgerufen werden kann („to call“).

Wenn Sie also ein Objekt `something` haben (das möglicherweise _keine_ Funktion ist) und Sie es wie folgt aufrufen (ausführen) können:

```Python
something()
```

oder

```Python

                // 2. Check if all their predecessors have completed (in a terminal state)
                // 3. Process each step (schedule or skip based on reactor failure behavior)
                plan.sortedNodes().stream()
                        // 1. Filter steps that are in CREATED state
                        .filter(BuildStep::isCreated)
                        // 2. Check if all predecessors are in a terminal state
