Re: [Boost-users] Serialization with pointer to const object

Hi Robert, I guess there's no direct way through which I can throw away const-ness during serialization. One way is to modify my class to remove const-ness for the pointee or use some temporary var which is non-const and serialize using that. Right? Or is there a better way - in that case I'll follow that till the issue gets resolved, hopefully, in boost. Regards, ~ Soumen Robert Ramey wrote:

The question is under consideration. It won't be resolved for a while. And such resolution might or might not mean a change. To get over the hump, you might want to just use a const_cast.

So finally to summarize it means that for now I cannot serialize pointers to const obj. And I need to update my code to throw away the const. Is that correct?

At the time the object needs to be instantiated and read, instead of dealing with a T const * p as:

p=new T; ar >> *p;

what's wrong with:

T * tmp=new T; ar >> * tmp; p=tmp;

This reminded me of the same issue with shared_ptr<const T> https://svn.boost.org/trac/boost/ticket/3123

I'm not sure Robert is applying const correctness correctly here.

There is no "const violation" here. If there was, you'd see a const_cast in the patch somewhere.
