- isEqualType() : bool
- Provided two types, return true if the types are equal (invariant).
- isTypeSubTypeOf() : bool
- Provided a type and a super type, return true if the first type is either equal or a subset of the second super type (covariant).
- areSameBuiltInScalar() : bool
- Built-in scalars may exist as different instances when a type loader overrides them. Compare by name to handle this case.
