## JSON Schema에서의 `examples` - OpenAPI

이들 중에서 사용합니다:

* `Path()`
* `Query()`
* `Header()`
* `Cookie()`
* `Body()`
* `Form()`
* `File()`

**OpenAPI**의 **JSON 스키마**에 추가될 부가적인 정보를 포함한 `examples` 모음을 선언할 수 있습니다.

   * on the deserialized instance.
   *
   * <p>When the underlying delegate throws an exception then this memoizing supplier will keep
