Normalerweise verwenden Sie:

* `POST`: um Daten zu erzeugen (create).
* `GET`: um Daten zu lesen (read).
* `PUT`: um Daten zu aktualisieren (update).
* `DELETE`: um Daten zu löschen (delete).

In OpenAPI wird folglich jede dieser HTTP-Methoden als „Operation“ bezeichnet.

Wir werden sie auch „**Operationen**“ nennen.

// Similar to bucket replication for PUT operation, soft delete (a.k.a setting delete marker) and
// permanent deletes (by specifying a version ID in the delete operation) have three states "Pending", "Complete"

## Cache directory

The cache directory must be exclusively owned by a single instance.

Deleting the cache when it is no longer needed can be done.  However this may delete the purpose of the cache
which is designed to persist between app restarts.

```kotlin
cache.delete()
```
 
## Pruning the Cache

Pruning the entire Cache to clear space temporarily can be done using evictAll.

```kotlin
cache.evictAll()
```

void FreeWhileResources(const TF_WhileParams* params) {
  TF_DeleteGraph(params->cond_graph);
  TF_DeleteGraph(params->body_graph);
  delete[] params->cond_inputs;
  delete[] params->body_inputs;
  delete[] params->body_outputs;
}

TF_WhileParams EmptyWhileParams() {
  return {0,       nullptr, nullptr, {nullptr, 0},
          nullptr, nullptr, nullptr, nullptr};
}

#### Operacje

"Operacje" tutaj odnoszą się do jednej z "metod" HTTP.

Jedna z:

* `POST`
* `GET`
* `PUT`
* `DELETE`

...i te bardziej egzotyczne:

* `OPTIONS`
* `HEAD`
* `PATCH`
* `TRACE`

W protokole HTTP można komunikować się z każdą ścieżką za pomocą jednej (lub więcej) "metod".
