[Boost-users] shared_ptr and global reset

Hi Boosters Let's say that I have many shared_ptr<A> sharing ownership to the same A object. At some point, I would like all those shared_ptr to point to a new Object A. Is there an easy (and safe) way to accomplish that? I know how to do that for one shared_ptr using either "reset", either operator = but in order to do this for all shared_ptr sharing ownership, the only way I could think of is through a registration mechanism (like the Observer pattern) but this sounds an overkilling process to me. So basically, is there a "global" reset method? Thanks ------------------------------------------ Matthieu Guillo ------------------------------------------
