De parameter `name` is gedefinieerd als `Optional[str]`, maar is **niet optioneel**, je kunt de functie niet aanroepen zonder de parameter:

```Python
say_hi()  # Oh, nee, dit geeft een foutmelding! 😱
```

De `name` parameter is **nog steeds vereist** (niet *optioneel*) omdat het geen standaardwaarde heeft. Toch accepteert `name` `None` als waarde:

```Python

            result.setCreatedTime(DfTypeUtil.toLong(source.get("createdTime")));
            result.setExpiredTime(DfTypeUtil.toLong(source.get("expiredTime")));
            result.setName(DfTypeUtil.toString(source.get("name")));
            result.setSessionId(DfTypeUtil.toString(source.get("sessionId")));
            return updateEntity(source, result);
        } catch (InstantiationException | IllegalAccessException e) {

            result.setCreatedBy(DfTypeUtil.toString(source.get("createdBy")));
            result.setCreatedTime(DfTypeUtil.toLong(source.get("createdTime")));
            result.setName(DfTypeUtil.toString(source.get("name")));
            result.setSortOrder(DfTypeUtil.toInteger(source.get("sortOrder")));
            result.setUpdatedBy(DfTypeUtil.toString(source.get("updatedBy")));
