흔히 이렇게 알고 있다
Calling cast on a CanonicalizedMap returns a valid Map wrapper that soundly checks and casts its keys and values for runtime lookups and iterations.
이 샘플의 작성자가 여기서 개발자나 모델이 기대할 법한 내용으로 적어둔 것이다. 아래 계약이 실제로 실행된 것이다.
컨트랙트
- Calling cast on a CanonicalizedMap returns a map view that throws a TypeError on value retrieval, because it delegates to the underlying map containing MapEntry elements instead of unpacking them.
- Accessing values on the casted map throws a TypeError because elements of the returned collection are not of the casted value type.
- Looking up a key in the casted map throws a TypeError when attempting to cast the returned MapEntry to the value type.
- Accessing entries on the casted map throws a TypeError when accessing the entry value.
