C++ Abstract Factory Implementation

[Suresh]

Hello
I am hoping someone can give me very needed help. I am wanting some C
+
+ code for 'C++ Abstract Factory'. I need code to be free. I am been
learning Design patterns.
I found some code on web but dont know which is one is ok.

Loki :in text book

http://sourceforge.net/projects/papafactory

http://sourceforge.net/projects/austria/

My colleague said I should look at boost library or use a standard
'factory' in C++. but I cannot find it.
I have read text book on Design Patterns and understand 'Abstract
Factory'.

Much thanks in adnace for help

I am very apologetic for multiple asking. This was not my intendings.
It was mistake and I have removed duplications.
I have decided to use first Papa Factory. It is with very good
documentation and just few .h files.
Austria for me now is difficult I not have enough experience. Book by
Andrei Alexandrecu is too much advanced for now too. But I think Papa
Factory is no support for multi-thread, but this is fine for now.

You said Austria C++ is difficult ?

I'd really love to know what you think is difficult. Below is an
example of a simple no constructor parameters case.

#include "at_factory .h"

class Interface {
};

int main()
{
Interface * n2 = at::FactoryRegi ster< Interface, char >::Create(2)( );
// n2 should really be an instance of Impl2
}

// this below can be in other linked in compile units
class Impl1 : public Interface {
};
AT_MakeFactory0 P( 1, Impl1, Interface, int);

class Impl2 : public Interface {
};
AT_MakeFactory0 P( 2, Impl2, Interface, int);

Please let me know what is so hard.

This Library is very powerful but I try to read the documentation but
is very complicated.
I do not think I need so powerful Library. Papa Factory is with
tutorial to make easy everything for beginer.
And Austria Factory is big because it is so powerful with smart
pointers.
