`Query`と`Path`（そしてまだ見たことない他のもの）では、[クエリパラメータと文字列の検証](query-params-str-validations.md)と同じようにメタデータと文字列の検証を宣言することができます。

また、数値のバリデーションを宣言することもできます:

* `gt`: `g`reater `t`han
* `ge`: `g`reater than or `e`qual
* `lt`: `l`ess `t`han
* `le`: `l`ess than or `e`qual

/// info | 情報

`Query`、`Path`、および後で見る他のクラスは、共通の`Param`クラスのサブクラスです。

それらはすべて、これまで見てきた追加のバリデーションとメタデータの同じパラメータを共有しています。

## 커스텀 Operation ID와 더 나은 메서드 이름 { #custom-operation-ids-and-better-method-names }

클라이언트에서 **더 단순한 메서드 이름**을 갖도록, operation ID가 **생성되는 방식**을 **수정**할 수 있습니다.

이 경우 operation ID가 다른 방식으로도 **유일**하도록 보장해야 합니다.
