vector <template>, c++, class, adding to vector
c++, templates, vector
Solution
having lots of functions like vectorOneAdd, vectorTwoAdd used in order to add elements to the vector is pointless. There must be a better way
There is:
class Cookie {
std::vector<Chocolate> chocolateContainer;
std::vector<Sugar> sugarContainer;
private:
template<typename T>
std::vector<T>& get_vector(const T&); // not implemented but particularized
// write one of these for each vector:
template<>
std::vector<Chocolate>& get_vector(const Chocolate&) { return chocolateVector; }
template<>
std::vector<Sugar>& get_vector(const Sugar&) { return sugarVector; }
public:
template<typename T>
void add(T element) {
auto& v = get_vector(element);
v.push_back(std::move(element));
}
};
Problem
I am trying to create a class thats going to draw elements from a set of vectors (and also hold these vectors as containers inside the class), but i feel that when managing the vector having lots of functions like vectorOneAdd, vectorTwoAdd used in order to add elements to the vector is pointless. There must be a better way, thats why i am asking here, I heard you can use templates to do it, but i am not quite certain how. Assistance needed. Don't want to have lots of pointless code in. Example of what I mean below: ``` class Cookie { std::vector<Chocolate> chocolateContainer; std::vector<Sugar> sugarContainer; void chocolateVectorAdd(Chocolate element); // first function adding to one vector void sugarVectorAdd(Sugar element); // second function adding to another vector } ``` Please use example code, thanks :)
