Hi, I am trying to create a Universal type in Ada such as "Object" in
Java so that I could define a function that returns a value in this
Universal type, then I could lower-cast value in this type to its
specific type such as String, Float or any user-defined types. Because
in Java if a method returns an Object, it could be casted to any other
types that are subtypes of Object. Is there a Universal type in Ada?
Could anyone tell me how to create such types in Ada, please?
