 * A descriptor for a <i>discrete</i> {@code Comparable} domain such as all {@link Integer}

First, you might want to see the basic ways to [help FastAPI and get help](help-fastapi.md).

## Developing

If you already cloned the [fastapi repository](https://github.com/fastapi/fastapi) and you want to deep dive in the code, here are some guidelines to set up your environment.

### Install requirements

Create a virtual environment and install the required packages with [`uv`](https://github.com/astral-sh/uv):

- **Concurrent Utilities** (`org.codelibs.core.concurrent`) - Thread-safe collections and concurrency helpers using modern concurrent APIs
- **Crypto & Security** (`org.codelibs.core.crypto`, `org.codelibs.core.security`) - Basic cryptographic utilities, message digest operations, and secure random generation
- **XML Processing** (`org.codelibs.core.xml`) - XML DOM utilities, SAX parser helpers, and schema validation support

        if (!flattenEnabled) {
            // When flattening is disabled, treat non-POM projects like parent POMs
            // Apply only basic transformations without flattening dependency management
            // However, BOMs still need special handling to transform packaging from "bom" to "pom"

* `apiKey`: アプリケーション固有のキーで、これらのものから取得できます。
    * クエリパラメータ
    * ヘッダー
    * クッキー
* `http`: 標準的なHTTP認証システムで、これらのものを含みます。
    * `bearer`: ヘッダ `Authorization` の値が `Bearer ` で、トークンが含まれます。これはOAuth2から継承しています。
    * HTTP Basic認証
    * HTTP ダイジェスト認証など
* `oauth2`: OAuth2のセキュリティ処理方法（「フロー」と呼ばれます）のすべて。
