Regarding from `RevocableInfo::Type` to `RevocableInfo`, do you mean change `RevocableInfo` from `message` to `enum`? I think it's better to define const in `Resources` instead of changing `RevocableInfo`'s type, e.g. `static const Resource::RevocableInfo::Type Resources::ALLOCATION_SLACK = Resource::RevocableInfo::Type::ALLOCATION_SLACK`. Regarding `flatten`, there're two options to me: * Option 1: add `RevocableInfo::Type` to as 3rd parameter in current `flatten` with `None()` as default vaule, and a new helper function to accept `RevocableInfo::Type` only without default value. The sample code is: ``` Resources flatten(string role = "*", Option<ReservationInfo> resveration = None(), Option<RevocableInfo::Type> revocable = None()) { ... if (revocable.isSome()) { flatten(revocable.get()); } else { // clear revocable info. } } Resources flatten(RevocableInfo::Type revocable) { foreach resources { resource.mutable_revocable()->set_type(revocable); } } ``` * Option 2: add new `flatten` functions but did not provide default value; `None()` means clear the `RevocableInfo::Type`. I perfer to Option 1 :). Any comments? - Klaus ----------------------------------------------------------- This is an automatically generated e-mail.
