My case is like that: I have a number of polymorphic objects which can be used or referenced by other objects. I put them (the polymorphic objects) in MIC. And if one changes its type (not only its value), its users know it automatically by shared_ptr. I think I need MIC with shared_ptr pointing to scoped_ptr. Am I right? Or is there other way to easy handle it? Thanks a lot. On Tue, Dec 20, 2011 at 3:02 PM, Andrew Holden < aholden@charteroaksystems.com> wrote:

It is just my guess. In fact I need MIC with shared_ptr to a scoped_ptr. The shared_ptr is used to count number of uses, while the scoped_ptr used to handle polymorphic objects. I feel a little nervous with that.
There should be no need for both pointer types. Shared_ptr handles polymorphic objects just fine.
A MIC holding shared_ptrs to your base class should do what you need, and the overhead associated with the shared_ptr should be negligible. _______________________________________________ Boost-users mailing list Boost-users@lists.boost.org http://lists.boost.org/mailman/listinfo.cgi/boost-users
