Hi all, I'm a happy user of Boost.Signal, as it brings great power to our software design in terms of loosening all the coupling between components. However, I recently come across a case where a single-shot slot is desired (i.e., a signal-slot connection that is automatically disconnected once the signal is invoked for once). In our current implementation, we have to keep boost::signals::connection object around with the slot implementation, so that it can disconnect it after the first invocation. However, we have this problem of boost::signals::connection management, since one signal may be connected to different signals and we have problem identifying the correct connection to be disconnected. So my question is: Is there any easier way (i.e., ways that doesn't involve the implementation of the slot function itself) that I can add a single-shot signal-slot connection? Any suggestion is appreciated.
