Overview

This class is part of a private API. You should avoid using this class if possible, as it may be removed or be changed in the future.

Note:

Within the mapping, we have a single object type that has a set union of the properties of the subtypes (and also a __typename keyword field).

Responsible for the mapping of a SchemaElements::UnionType.
