  package de.polygonal.ds
  {
A list node. The node acts as a data container and also holds a reference to next and previous node in the list. 

  
          public class @ax-lib-as-de-polygonal-ds-DListNode
          {
The node's data. 

  
                  public var data:*;
The next node in the list being referenced. 

  
                  public var next:@ax-lib-as-de-polygonal-ds-DListNode;
The previous node in the list being referenced. 

  
                  public var prev:@ax-lib-as-de-polygonal-ds-DListNode;
Initializes a new node that stores the given item.
parameter: obj The data to store in the node. 

  
                  public function @ax-lib-as-de-polygonal-ds-DListNode(obj:*)
                  {
                          next = prev = null;
                          data = obj;
                  }
A helper function used solely by the DLinkedList class for inserting this node after a given node.
parameter: node A doubly linked list node. 

  
                  public function insertAfter(node:@ax-lib-as-de-polygonal-ds-DListNode):void
                  {
                          node.next = next;
                          node.prev = this;
                          if (next) next.prev = node;
                          next = node;
                  }
A helper function used solely by the DLinkedList class for inserting this node in front of a given node.
parameter: node A doubly linked list node. 

  
                  public function insertBefore(node:@ax-lib-as-de-polygonal-ds-DListNode):void
                  {
                          node.next = this;
                          node.prev = prev;
                          if (prev) prev.next = node;
                          prev = node;
                  }
A helper function used solely by the DLinkedList class to unlink the node from the list. 

  
                  public function unlink():void
                  {
                          if (prev) prev.next = next;
                          if (next) next.prev = prev;
                          next = prev = null;
                  }
Returns a string representing the current object. 

  
                  public function toString():String
                  {
                          return "[@ax-lib-as-de-polygonal-ds-DListNode, data=" + data + "]"
                  }
          }
