> ECOM - backport to ER6.1?

Anonymous — Sun, 13 Feb 2005 22:40:17 +0100

I've been working with this quite a lot lately, and found it very useful. However, after some usage, I've found that the need to pass in a pointer to a pointer (which some other platforms' implementations' do in order to allow for smart pointers) is obviated on Symbian by the use of the CleanupStack. So to make for some cleaner code, I've changed it in my own implementation to:

virtual MUnknown * QueryInterfaceL( TInt aInterfaceId /* IN */ ) = 0;

Just thought I'd share. I'll see about updating the download at some point too.

I have considered the IPR issues, but I am not a lawyer. Please see the copyright notice in the source code, where I state that the code is provided as-is, with no guarantee that it doesn't violate anyone else's IPR.

Ideas like interface querying show up all over the place and (I believe) pre-date COM, and the Mozilla open source project has analogues of IUnknown, so I can't imagine this is a problem, but again, IANAL.

Hi, Finally, someone else who finds ECOM an incomplete design! I have also been keenly interested in this sort of extension. Good beginnings!

Have you considered the IPR issues with using this these interfaces and the ideas embodied in COM.

I don't believe I'm permitted to comment on this. Perhaps someone from Nokia could fill us in on the details...

On a more general note, there is one thing that keeps me from using ECOM at the moment, even though I could think of several places in my code where I would like to: the lack of a backport to ER6.1 - as long as there is still a sizable population of Series 60 1.x devices out there (Sendo X, N-Gage QD being among the recent additions to the family...) I can't see how I could restrict the audience for my applications for just a bit of developer convenience...

In my mind, this is going to delay widespread usage of ECOM by at least a year or two, until developers can afford to sacrifice backward compatibility to ER6.1 devices.

Or am I completely off base, and there is already such a thing?

The ECOM examples distributed with the SDK's seem to view ECOM as merely a tool for DLL polymorphism. ECOM does help with this, but I believe it can do much more. The idea is to be entirely ECOM compatible, but to add a couple of conventions which give ECOM the salient features of COM.
