C++ unique static id and class name with base class

Question

Having class TaskBase, each derived class of it must have name and unique id.

The TaskBase is something like below:

class TaskB         


        

Answer 1

I suggest implementing pure virtual methods for obtaining the class name and ID in the base class. The descendants would need to provide the unique names and IDs.

class TaskBase
{
    public:
        virtual std::string  get_task_name(void) const = 0;
        virtual unsigned long get_task_id(void) const = 0;
};

I took @VoidStar's suggest a step further and put the names into a (single) common class:

class TaskNames
{
  protected:
    static std::string get_tas1_name();
};

class Task1: public TaskBase, public TaskNames
{
//...
};
