Hi folks! I'm writing a factory class that should be able to return singleton instances of a number of different types, depending on the given parameter. The method would look something like this, but the way I'm referencing the singleton's static method is obviously wrong: public function getService($singletonClassName) { return $...
I am always confused about static variables, and the way memory allocation happens for them. For example: int a = 1; const int b = 2; static const int c = 3; int foo(int &arg){ arg++; return arg; } How is the memory allocated for a,b and c? What is the difference (in terms of memory) if I call foo(a), foo(b) and foo(c)? ...

I would like to have a constant set in my class which would be visible for all instances of the class. First, I do not know if I need to declare it as "static". As far as I understand any changes of a static field (done by one of the instances) will be seen by other instances (so static variable is not bound to a specific instance). Mor...

We have a Formatter subclass for each table, to provide the definition of that table: how many columns it has, and what is the name, format and validator of each column. The getters which supply this data are then called...
