and those default values won't be included in the response, only the values actually set.

So, if you send a request to that *path operation* for the item with ID `foo`, the response (not including default values) will be:

```JSON
{
    "name": "Foo",
    "price": 50.2
}
```

/// info

e esses valores padrão não serão incluídos na resposta, apenas os valores realmente definidos.

Então, se você enviar uma solicitação para essa *operação de rota* para o item com ID `foo`, a resposta (sem incluir valores padrão) será:

```JSON
{
"name": "Foo",
"price": 50.2
}
```

   * doesn't work: Because nullness analyses typically infer the nullness of local variables,
   * there's no way to assign a {@code @Nullable T} to a field {@code T foo;} and instruct the
   * analysis that that means "plain {@code T}" rather than the inferred type {@code @Nullable T}.
   * (And even if annotations on local variables were permitted as an optional hint, no annotation

        MediaType.create("text", "plain")

            .withParameter("something-else", "crazy with spaces")

            .withParameter("normal-thing", "foo")
            .toString());
  }

例えば、上記のモデルは以下の様なJSON「`オブジェクト`」(もしくはPythonの `dict` ) を宣言しています:

```JSON
{
    "name": "Foo",
    "description": "An optional description",
    "price": 45.2,
    "tax": 3.5
}
```

...`description` と `tax` はオプショナル (デフォルト値は `None`) なので、以下のJSON「`オブジェクト`」も有効です:

```JSON
{
    "name": "Foo",
    "price": 45.2
}
```

## パラメータとして宣言

*パスオペレーション* に加えるために、パスパラメータやクエリパラメータと同じ様に宣言します:
