これでヒーローの正体は守られます！🥷

また、`id: int` を再宣言します。これにより、API クライアントとの間で「常に `id` が存在し、`int` である（`None` にはならない）」という契約を結びます。

/// tip | 豆知識

戻り値のモデルで、値が常に存在し常に `int`（`None` ではない）であることを保証すると、API クライアント側のコードははるかにシンプルに書けます。

加えて、自動生成クライアントのインターフェースも簡潔になり、あなたの API とやり取りする開発者体験が向上します。😎

`HeroPublic` のフィールドは `HeroBase` と同じで、`id` は `int`（`None` ではない）として宣言されます:

* `id`
* `name`
* `age`

     * @param currentNode             The current node that is being evaluated.
     * @param parentKeyName           The name of the parent key object for the current node. null if none.
     * @param objectKeyFinders        A Map of object keys to find and their associated transformation by parent Object
