Thread: Problem with "this" pointer

hi I am trying to create a linked list class. My problem is the "this" pointer. See, because the member functions cannot refer to the immediate variable instance by name, I must use the "this" pointer. Look at it so far, with only one member function complete:

Code:

class LinkedList
{
public:

int AddTo ( LinkedList *head ) {

this = new LinkedList;  //<-- ERROR: NON-LVALUE IN ASSIGNMENT

if( !this ) return 0;

if( !head ) {
head = this;
head->prev = 0;
head->next = 0;
return 1; }

LinkedList *b = head;

int nodeCount = 1;

while( b->next ) {
b = b->next;
nodeCount++; }

b->next = this;
this->prev = b;

return nodeCount; }


LinkedList *prev;    LinkedList *next;
};

I have tried everything, but it just will not compile.

Can anyone give me some direction?

You are right, but I need to allocate for "this" instance, since all objects will be declared as pointers to deallocate. Wait a minute. If C++ class instances get ~destructors, then C++ objects can be allocated/deallocated like a pointer while declaring concrete intances--right? So in essence, don't use pointer intances, just call the ~destructor on a real object. Is that correct?

this is read only. You have to find another solution. I made a linked list class that contained a pointer to a listItem structure, the definition as such:

struct listItem
{
int value;
listItem *next;
}

That paradigm will work.
