Hello!
I'm looking for some help with the c++ syntax.
What I want to do is the following: I have a template
class X<T>. Within X I want to declare a nested class N.
My approach is the following:
template<class T>
class X
{
class N; // Declaration here, definition follows
// below. As far as I know, this is/will
// be allowed with std-C++. (r.9.7)
N* np; // Question 1: This should be legal, but
N n; // this might not.
};
template<class T>
class X<T>::N // Question 2: Is this syntax correct?
{
void N();
T t;
};
template<class T>
void X<T>::N::N() // Solution 1: IMO this makes sense.
: t()
{
}
template<class T>
void X<T>::N<T>::N() // Solution 2: Could have to be this way
// as well, but solution 1 looks nicer.
: t()
{
}
Thank you in advance for your answers.
