Question

I have a situation: In a single Solution I have two Projects. I need to extend the Class:Foo used in Project:A so that I can add new functionality required in Project:B without changing its name. Problem is: Class:Foo already contains (i.e. has a) Class:Bar and is contained by Class:Goo in both Project:A & Project:B. In Project:B I am inheriting Class:Goo into Class:Goo_Ex; but I need to also extend both: Class:Foo and Class:Bar with companion functions.

To make it more clear – I could accomplish this using the following crude method:

/* Project:A-Class:Foo */

class Foo
{
    .
    .
    .
# ifdef PROJECT_B
    fnExtended();
# endif
};

but that would litter my code in Project:A.

A possible solution that I can think of is to use Inheritance and have Class:Foo_Global Inherited-[Only] as Class:Foo in Project:A and Inherited-[Extend] as, again, Class:Foo in Project:B; same for Class:Bar. But is their a more straight forward solution..?

Answer 1

I think your proposed solution (to hide the current Foo as some other class name and inherit from it in a new Foo class in both projects) is how you should do it.
