RE: [GD-General] Multiple Inheritance and RTTI

[Gareth L. <GL...@cl...>]

COM basics are extremly simple to implement.

You really need a standard way to implement a "Give me this interface"
function. (QueryIterface)
A standard way of iding interfaces (GUIDs or FourCCs or whatever)
And a base interface that concreate class implements.  (IUnknown)

A lot of COM also uses Factories, Ref counting and sometimes smart pointers.
They are not needed, but tend to fit well ( For example ref counting works
nice with QueryInterface because you might have a few interfaces to the same
object ).

Again, Inside COM is a must read if you plan on having a COM like system.
