从C ++中的类模板中的函数调用另一个成员函数

Question

Let's say I have a class template named myTemplate with some member variables and two member functions, funcTempA , and funcTempB .

template <class T>
class myTemplate
{
    private:
        //member variables
    public:
        T* funcTempA(T *arg1, T *arg2);
        T* funcTempB(T *arg1, T *arg2);
}

funcTempB calls funcTempA in its implementation. I just want to know what will be the correct syntax for calling it.

template <class T>
T* funcTempB(T *arg1, T *arg2)
{
    //how to call funcTempA here?
}

Answer 1

To call a member variable or a member function, you can use this keyword.

template <class T>
T* myTemplate<T>::funcTempB(T *arg1, T *arg2)
{
    this->funcTempA(arg1, arg2);
    return ...;
}

You can read this to know ore about this

Answer 2

Just call it directly, such as:

return funcTempA(arg1, arg2);

BTW: The definition of the member function funcTempB seems wrong, might cause some unexpected errors.

template <class T>
T* myTemplate<T>::funcTempB(T *arg1, T *arg2)
// ~~~~~~~~~~~~~~~
{
    return funcTempA(arg1, arg2);
}
