I have a structure as: stateStack a; typedef std::stack < state*, std_deque<state*>> stateStack How can I serialize this structure? I cannot find any std::stack in the serialization header file. --------------------------------- Yahoo! DSL Something to write home about. Just $16.99/mo. or less

I don't think it's psossible, because std::stack doesn't expose enough information. Either use deque/vector directly or inherit from std::stack to get access to the inner deque. Regards, Bruno

Inheriting from the std::stack is horrible idea. It is not portable. Not to mention that stack lacks a virtual destructor. Nathan Moore

You are right about the destructor. One has to be carefull. I think it's portable. The standard requieres the container to be protected for a reason. Bruno

?? How so?

So use private inheritance if you're worried. -- Dave Abrahams Boost Consulting www.boost-consulting.com
Mostly because I had forgotten that stack provides a protected member to access the base structure directly. I was assuming that you would have to resort to tricks like '#define private public'. The only real problem is I shot off my mouth before I had checked. However my point about the lack of a virtual destructor is still valid, certainly not a deal breaker though. Nathan Moore

Is this a reasonable implementation? I didnt knew how the better way to call the serialization of something inside the serialization code, so I called the serialize free function to serialize the stack internal container. Hope it works for types other than the STL containers.

Looks like it might work. Make a test and upload the whole thing to the vault Robert Ramey Felipe Magno de Almeida wrote:

Look at the libs/serialization/test directory - you'll find lots of tests there. Robert Ramey Felipe Magno de Almeida wrote:

Shouldn't the get_aux::get method be explicitally inlined? This should make the M$ pragma unnecessary. Felipe Magno de Almeida wrote:

Probably, inlining is good, but I dont understand how it would make the MS pragma unnecessary. The #pragma once (is this you're talking about?) works like the macro guards of the header. The difference is that it makes it faster for the preprocessor, since it doesnt need to reopen the file to see that nothing will be added to the preprocessed file. Or are you saying that the header guards arent needed too? Thanks, -- Felipe Magno de Almeida Developer from synergy and Computer Science student from State University of Campinas(UNICAMP).

Sorry, I had to look at it. And being a booster - I couldn't leave well enough alone. So I made your version a little shorter - maybe too short for certain compilers. Robert Ramey Felipe Magno de Almeida wrote:
