I have a class that represents a level (it has monsters, platforms, characters classes associated...), it uses STL containers and QString (which I could remove)
My question is: How can I save automatically those classes on hard disck? I mean, without writing large Load/Save/Traverse methods, is there any way or library or STL function?
I believe BOOST have something, but not sure. Does Qt have anything? What do you recommend me?
Thanks in advance.
May be QDataStream might be of some help to you
Must I save my class manually? Or is there anything like: something << my_class?Quote:

You can overload the operators << and >> for your classes. They are already provided for native types and many Qt types such as QString, QPoint, QList.

What does it have that QDataStream doesn't do? I really can't see the difference.Quote:

I'm not sure how a serialized signal would look like :)
By the way, the explanation about QDataStream on S11nQt website is really lame. s11n is as proprietary as QDataStream :) And (de)serializing Qt objects in a non-Qt environment wouldn't make sense so you are limited to the Qt environment anyway and QDataStream is available there.
What about serializing without a QT enviroment?
BTW, thanks for replies.
It's hard to use Qt if you don't have it available...Quote:

Have a look at the boost serialization library
