Node Class Reference

Detailed Description

This provides the necessary pointers to build doubly-linked lists:

• nNext points to the next Node, and is null if *this is first in the list.
• nPrev points to the previous Node, and is null if *this is last in the list.
• nList is a back pointer to the current NodeList.

A given Node can only be part of one NodeList. One can unlink the object with

obj->list()->pop(obj);
