After i define a boost::function using bind to a member function of some
signature...
Can i change the instance to have as "this" in such function for another of
the same type? Maybe pass it as a parameter at call time?
Why would i want that?
Imagine i have some class A that dispatches calls for a big amount of
methods. The requests for such calls come serialized, and the method is
selected by its name (string).
So there should be a std::map >
to be able to make the actual call after i know what the name is without
doing a switch or a huge ammount of ifs.
So A has that map, and has it populated with member functions of itself.
But i may have many instances of A. (actually, one for each of many
threads). So having that map in each is a waste of resources. So maybe i
could declare the map as static, so that it is shared between all instances
of A. But to do that, i would need to be able to tell the function in the
map im about to invoke, what its "this" should be at this time.
Did i explain myself clearly?
Thanks a lot for your time :)
