mapSchema transform MapperKind.TYPE return value

[kennyjwilli]

I am working on a project that specifies directives on types, similar to the Enforcing Access Permissions example. It looks something like this.

type User @auth(requires: USER) {
  name: String
}

I've read the docs on implementing that @auth directive. The implementation shows the mapSchema call using both TYPE and OBJECT_FIELD. In the latter, we actually call the underlying resolve function if the user has the right role. If they do, we permit access to the particular object field.

In my case, I'd like all object fields to be resolved first. After resolution, I am able to determine if the user has the correct role to view the object. Is this possible with mapSchema?
