## Pydanticのモデル

<a href="https://docs.pydantic.dev/" class="external-link" target="_blank">Pydantic</a> はデータ検証を行うためのPythonライブラリです。

データの「形」を属性付きのクラスとして宣言します。

そして、それぞれの属性は型を持ちます。

さらに、いくつかの値を持つクラスのインスタンスを作成すると、その値を検証し、適切な型に変換して（もしそうであれば）全てのデータを持つオブジェクトを提供してくれます。

      AtomicReferenceFieldUpdater.newUpdater(
        RealConnectionPool::class.java,
        Map::class.java,
        "addressStates",
      )
  }
