Syntax for nested class destructor and copy constructor

[prestokeys]

class PrimeList {
  public:
           
	    struct ListNode {
		    ItemType data;
		    ListNode *next;
		    ~ListNode ();  // destructor
		    ListNode (const ListNode &N);  // copy constructor
		    ListNode & operator = (const ListNode &N);	
 } ;
    ListNode *first, *last;
} ;

For the assignment operator, I figured it out:
PrimeList::ListNode & PrimeList::ListNode::operator = (const PrimeList::ListNode &N) { }

But I cannot figure get the syntax correct for the destructor and copy constructor for ListNode. What is it?

PrimeList::ListNode::~PrimeList::ListNode {
and
PrimeList::ListNode::PrimeList::ListNode (const ListNode &N) {
gives error.

Try

PrimeList::ListNode::~ListNode() {}

Nope. Error reads:
[Error] invalid use of destructor '~PrimeList::ListNode' as a type

[vlad from moscow]

I showed you the correct syntax, This error has nothing common with the definition of the destructor I showed.

Ok, it compiled. And from your answer, I figured that for the copy constructor the syntax is:
PrimeList::ListNode::ListNode (const ListNode &N) {}

Thanks.
