Suppose I have a class with 2 static functions:
class CommandHandler
{
public:
static void command_one(Item);
static void command_two(Item);
};
I have a problem DRY problem where I have 2 functions that have the exact same code for every single line, except for the function that it calls:
void CommandOne_User()
{
// some code A
CommandHandler::command_one(item);
// some code B
}
void CommandTwo_User()
{
// some code A
CommandHandler::command_two(item);
// some code B
}
I would like to remove duplication, and, ideally, do something like this:
void CommandOne_User()
{
Function func = CommandHandler::command_one();
Refactored_CommandUser(func);
}
void CommandTwo_User()
{
Function func = CommandHandler::command_one();
Refactored_CommandUser(func);
}
void Refactored_CommandUser(Function func)
{
// some code A
func(item);
}
I have access to Qt, but not Boost. Could someone help suggest a way on how I can refactor something like this?
