Question

Having a vector containing pointers to objects then using the clear function doesn’t call the destructors for the objects in the vector. I made a function to do this manually but I don’t know how to make this a generic function for any kind of objects that might be in the vector.

void buttonVectorCleanup(vector<Button *> dVector){     Button* tmpClass;     for(int i = 0; i < (int)dVector.size(); i++){         tmpClass = dVector[i];          delete tmpClass;     } } 

This is the function I have that works fine for a specific type of object in the vector but I’d like a single function that could take any kind of vector with object pointers.

The best thing to do is use smart pointers, such as from Boost. Then the objects will be deleted automatically.

Or you can make a template function

template <class T> void vectorCleanup(vector<T *>& dVector){     T* tmpClass;     for(vector<T*>::size_type i = 0; i < dVector.size(); i++){         tmpClass = dVector[i];          delete tmpClass;     } 

}
