Re: [Boost-users] [ptr_container] No insert(it, [key, ]value) in associative pointer container?

iterator insert( iterator, ref_pair ).

Would this be satisfactory?

Hi, I was thinking of something along the lines of

iterator insert(iterator, const key_type &key, std::auto_ptr<T> ptr);

and

iterator insert(iterator, const key_type &key, mapped_type val);

to mimic the insert overload that doesn't take the iterator.

Ok. I'll add those.

And while you're at it, I've noticed that the member std::pair ptr_map_adapter::iterator(key_type &key, mapped_type x)

takes the key as a non-const reference, is there a reason for that?

Yes. It provides stronger exception-safety guarantees (though not bullet-proof) since then creating a key must be done in a seperate statement. -Thorsten
