Hmmm... (Not in the shower this time. Well, two outa' three ain't bad.)
If we have the object's entire type available:
- Stubs can be:
- a subclass of the ActualClass they're stubbing, (thus inheriting all
the member variables, which makes them the right size)
- whose constructor uses an overloaded stub-constructor for the superclass
- and whose member functions, if they really need the data, are overridden
to grab the disk data, mutate, and call the superclass member function.
- And on platforms where mutation is not possible, the shepherd types are
just the real type with an "I'm real/get real" test/member function call
at the start of each must-be-real member function. (Extra test per member
function, but that's quicker than a forwarder's extra subroutine call...)
THAT's portable. We can switch platforms by switching the definition of
the macro that marks the must-be-real member functions for stubble.
Bingo
