Hey everyone, I was just having a look at the new boost::variant vlass, and I was expecting to be able to do something like: boost::variant var; var = 5; int i = boost::get<int>(var); // fine float f = boost::get<float>(var); // throws As the comments show, asking for the variant's value using get<int> works fine but get<float> throws an exception as it is an unmatched type. So it seems that before you can retrieve the value of the variant you need to know its type? How do you check what type the variant is currently holding? This would work but is inefficient/ugly: boost::variant var; var = 5; std::stringstream str; str << var; int i = atoi(str.str()); float f = atof(str.str()); I was hoping to use the variant class to implement scripting language style variables where you can get/set them to be any type (which seems to work fine) and also retrieve them to any type (though retrieving a string as a bool may not always make too much sense).
