## Pydantic 모델

<a href="https://docs.pydantic.dev/" class="external-link" target="_blank">Pydantic</a>은 데이터 검증(Validation)을 위한 파이썬 라이브러리입니다.

당신은 속성들을 포함한 클래스 형태로 "모양(shape)"을 선언할 수 있습니다.

그리고 각 속성은 타입을 가지고 있습니다.

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

 * repository system instance needed, new instance of this class must be created. For proper shut down of returned
 * repository system instance(s) use {@link RepositorySystem#shutdown()} method on supplied instance(s).
 * <p>
 * Since Resolver 2.0 this class offers access to various components via public getters, and allows even partial object
 * graph construction.
