How do you clear a stringstream variable?

Question

I've tried several things already, std::stringstream m; m.empty(); m.clear(); both of which don't work.

Answer 1

Just did this yesterday, adding a toJSON() method - use the .str() method. This overloaded method returns a std::string when there's no argument, but the overloaded method accepts a text string that sets the object:

stringstream ss;

ss.str("");
