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")
```

  protected void verify(List<E> elements) {}

  /** Executes the test. */
  @SuppressWarnings("CatchingUnchecked") // sneaky checked exception
  public final void test() {
    try {
      recurse(0);
    } catch (Exception e) { // sneaky checked exception
      throw new RuntimeException(Arrays.toString(stimuli), e);
    }
  }

  private void recurse(int level) {

      queue.add(submittedTask);
      workerRunningState = QUEUING;
    }

    try {
      executor.execute(worker);
    } catch (Throwable t) {
      // Any Exception is either a RuntimeException or sneaky checked exception.
      synchronized (queue) {
        boolean removed =
            (workerRunningState == IDLE || workerRunningState == QUEUING)
                && queue.removeLastOccurrence(submittedTask);
