Storing member function pointers of derived classes in map
- by Kiran Mohan
Hello,
I am trying to implement a factory for two classes Circle, Square both of which inherits from Shape.
class Shape {
public:
virtual static
Shape * getInstance() = 0;
};
class Circle : public Shape {
public:
static const std::string type;
Shape * getInstance() {
return new Circle;
}
};
const std::string Circle::type = "Circle";
class Square : public Shape {
public:
static const std::string type;
Shape * getInstance() {
return new Square;
}
};
const std::string Square::type = "Square";
I want to now create a map with key as shape type (string) and value as a function pointer to getInstance() of the corresponding derived class. Is it possible?
Thanks,
Kiran
