I'm messing just now learning about singletons and was wondering if it is at all possible to change your singleton at all? For example I created a date Singleton and I know I can only have one constructor controlling it but is it possible to change it later on? Here's what my main file looks like.
1 2 3 4 5 6 7 8 9 10
Date *date1 = Date::instance(3, 2014, "March");
date1 = Date::instance(5, 2014, "May");
which works just fine but I've tried everything I can to be able to change the values later on and can't figure out how to do it. I understand Singletons are made so you don't have multiple constructors but is it possible to change its values at all later on?
