Re: [Boost-users] Change return type automatically

The best that you can do with a runtime id is:

template<class Args...> void A::connect(SignalIds id, const Args& args...) { switch(id) { case VoidSignal: m_voidSignal.connect(args...); break; case StringSignal: m_stringSignal.connect(args... ); break; } }

I've already thought of this.

If you can use compile time constants instead of runtime values, you can use indices into a fusion::vector.

The SignalId I'm talking about is a compile time constant (an enum) I'm trying this, but could not get anywhere for the past few days. Any pointers on this ? Thanks, Surya Surya
