このようにして依存関係を「パラメータ化」できます。いまや `"bar"` が属性 `checker.fixed_content` として中に保持されています。

## インスタンスを依存関係として使う { #use-the-instance-as-a-dependency }

その後、`Depends(FixedContentQueryChecker)` の代わりに `Depends(checker)` でこの `checker` を使えます。依存関係はクラスそのものではなく、インスタンスである `checker` だからです。

依存関係を解決するとき、**FastAPI** はこの `checker` を次のように呼び出します:

```Python
checker(q="somequery")
```

   * true when removing a connection from the pool; otherwise a racing caller might get it from the

   * connection from the pool.
   *
   * Once true this is always true. Guarded by this.
