Andrea Fontana:
class Known { void* data; // external data by c api int type; // 0 for int, 1 for string, etc. .. }How can I implement a method like this? Known known; // <-- suppose known.type == 1; string s = known.value(); // <-- automatic
To do this Known.value() needs to return different types according to the run-time value of Known.type. This is not possible in a statically typed language... You need to find other solutions.
