So other than that, COM interfaces and CORBA interfaces share the same features? As for reference counting - that just means that as soon as the reference count for an Interfaces reaches zero, it gets automatically freed? CORBA then rather treats them like classes - you can have no other objects referencing the class, yet it stays in memory. You always need to free it off manually. > point of view see this chapter of Delphi in a Nutshell by By Ray > Lischner: > http://www.oreilly.com/catalog/delphi/chapter/ch02.html Thanks for the link and quote. It already makes more sense. Hopefully more reading about the topic will strengthen the knowledge when to use Interfaces and when to use Class Inheritance. > I'll try to find some old links about articles I've read years ago. That will be very much appreciated. Thanks.
