Question

I’m creating event system. It’s based under boost::signals. To make the work easier I’m using typedef for the function signatures.

Everything is okey until I need creating of some new event trought event’s system method. I have to create the typedef dynamically on given type to the template function. The problem is the name of typedef.

Some pseudocode I would have:

template<typename EventType>
void create(const string &signalName)
{
   typedef EventType signalName;
   // ...
}

Is it possible to make such typedef (their names) with some passed string or data or something else? I don’t want to make user care about of this.

UPD: So, I have some typedefs list of function signatures – events. I have some templated function for connecting slots, for example. I don’t want to force user to input signature by his hands again every time (user is programmer which will use the event system). So I just use my typedefs from special namespace into template argument.

Answer 1

typedefs only matter during compilation. As far as I know it’s just an alias for a type.
