[Opencxx-users] Persistence?

[<j....@at...>]

I just discovered OpenC++ and really like the idea.  One of the things 
mentioned as a possibility (and what led me to find OpenC++) is a persistence 
mechanism.  I looked through the samples and have Googled and don't see anyone 
having defined a persistence mechanism in OpenC++.  (I would have searched the 
archives for this list too, if there had been any :)).

So, I am left wondering, what is probably a FAQ, are there any persistence 
abilities already defined using OpenC++?  Has anyone developed one?

What I am looking for would be something similar to a persistent keyword that 
could be defined with a class (persistent class Class).  This would then 
generate some sort of method (something like an ostream& operator<<(Class&) 
method) if one isn't present, similarly to the way a default constructor is 
created when one isn't supplied.  There might be better ways to do it, that's 
just what has come to me so far.

Also, what about say profiling methods on a class?  You could put in a profile 
keyword that would generate a prefix and postfix method.  I guess this is 
similar to the after and before accessors and could be used as such.  Hm.

Just some random thoughts and questions.  I don't want to duplicate anything 
anyone has done before, and would be interested in hearing of the pitfalls of 
trying something like this.  I'm afraid my exuberation has blinded me to the 
potential pitfalls this early in my consideration :)

Thanks,

Jay

Hi,

I am not sure if this is what you are looking for, but did you have a look
at coldstore.sourceforge.net?
