`.add_task()` 함수는 다음과 같은 인자를 받습니다 :

- 백그라운드에서 실행되는 작업 함수 (`write_notification`).
- 작업 함수에 순서대로 전달되어야 하는 일련의 인자 (`email`).
- 작업 함수에 전달되어야하는 모든 키워드 인자 (`message="some notification"`).

## 의존성 주입

`BackgroundTasks`를 의존성 주입 시스템과 함께 사용하면 _경로 작동 함수_, 종속성, 하위 종속성 등 여러 수준에서 BackgroundTasks 유형의 매개변수를 선언할 수 있습니다.

**FastAPI**는 각 경우에 수행할 작업과 동일한 개체를 내부적으로 재사용하기에, 모든 백그라운드 작업이 함께 병합되고 나중에 백그라운드에서 실행됩니다.

        // Verify flags (RECURSIVE_TREE + NOTIFICATIONS)
        int expectedFlags = DirectoryLeaseContext.DIRECTORY_LEASE_FLAG_RECURSIVE | DirectoryLeaseContext.DIRECTORY_LEASE_FLAG_NOTIFICATIONS;
        assertEquals(expectedFlags, SMBUtil.readInt4(buffer, 68));

        // Verify notification filter
        assertEquals(0x1F, SMBUtil.readInt4(buffer, 72));
    }

    @Test

        assertFalse(entry1.hasChild("subfolder"));
        assertTrue(entry2.hasChild("subfolder"));
        assertFalse(entry2.hasChild("document.txt"));

        // Test individual change notification
        directoryLeaseManager.handleDirectoryChange(dir1, "document.txt", DirectoryChangeNotifier.DirectoryChangeType.FILE_REMOVED);

        // Only first directory should be affected

`.add_task()` は以下の引数を受け取ります:

* バックグラウンドで実行されるタスク関数 (`write_notification`)。
* タスク関数に順番に渡す必要のある引数の列 (`email`)。
* タスク関数に渡す必要のあるキーワード引数 (`message="some notification"`)。

## 依存性注入

`BackgroundTasks` の使用は依存性注入システムでも機能し、様々な階層 (*path operations 関数*、依存性 (依存可能性)、サブ依存性など) で `BackgroundTasks` 型のパラメーターを宣言できます。
