2021-08-12Add DataView (#1955)Jack Koenig
DataView is a mechanism for "viewing" Scala objects as a subtype of `Data`. Often, this is useful for viewing one subtype of `Data`, as another. One can think about a DataView as a cross between a customizable cast and an untagged union. A DataView has a Target type `T`, and a View type `V`. DataView requires that an implementation of `DataProduct` is available for Target types. DataProduct is a type class that provides a way to iterate on `Data` children of objects of implementing types. If a DataView is provided for a type T to a type V, then the function .viewAs[V] (of type T => V) is available. The object (of type T) returned by .viewAs is called a "View" and can be used as both an rvalue and an lvalue. Unlike when using an .asTypeOf cast, connecting to a "View" will connect to the associated field or fields of the underlying Target. DataView also enables .viewAsSupertype which is available for viewing Bundles as a parent Bundle type. It is similar to .viewAs but requires a prototype object of the Target type which will be cloned in order to create the returned View. .viewAsSupertype maps between the corresponding fields of the parent and child Bundle types.
