Question

I try

template<class T>
struct getData
{
    boost::shared_ptr<T> operator()()
    {
        return boost::shared_ptr<T>(new T());
    }
};

struct getVector : public getData<std::vector<int>>{};

I want to spesify () return via inheritence… but it seems to not return desired type. What do I do wrong?

Answer 1

Don’t you need the return type to be

boost::shared_ptr<T> operator()()
^^^^^^^^^^^^^^^^^^^^
{
    return boost::shared_ptr<T>(new T());
}
