Example C++ Factory Source code

[joseph.xavier79]

Hello
Can anyone either post or point me in the right direction of some
example C++ code to implement an (Abstract) Factory.

Many Thanks

Joseph

I agree, Alexandrescu's code is the best you can get. However, I
recommend you to read the first two chapters of the book (and maybe
the one about typelists) before reading the one about abstract
factories if you really trying to understand his code.

Thanks Guys thats very helpful. A few other others have also suggested
'Loki'' and I have Alexandrescu's book on order now.
But I have also seen told its quite a tough book to read.
I also found a nice little tutorial at http://papafactory.sourceforge.net

It will be tough the first time, but once you understand it, it will
change the way you think about C++.
The book is amazing.

I am finding the chapter on typelists very wierd, and your right its
not C++ as I know it. At first I couldn't see the point of typelists
and what they could be used for, but then I saw that they were being
heavily used in Papafactory. The author of Papafactory seems to be
using typelists in derived classes to let the factory know what the
signature of the constructor is that the factory should call to
instantiate the class.
But I think your right, one reading will not be sufficient.
