         1.  节点之间的关系

         2.  节点的添加操作

         3.  节点的删除操作

         4.  节点的查找操作

         5.  节点的替换操作

         6.  节点属性操作

0.  节点操作相关参数

    /** 当前节点的Z轴顺序 **/
    private int m_nZOrder = 0;
    /** 当前节点的子节点 **/
    private Vector m_vChildren = new Vector();
    /** 当前节点的父节点 **/
    private CCNode m_Parent;

/*white-space: pre;*/
}
.csharpcode pre { margin: 0em; }
.csharpcode .rem { color: #008000; }
.csharpcode .kwrd { color: #0000ff; }
.csharpcode .str { color: #006080; }

1.  节点之间的关系

                             

2.  节点的添加操作

    /**

      * addChild(给当前节点添加子节点)
      * @Title: addChild
      * @Description:
      *    1. 如果节点为null或者已经有父节点的话则退出
      *    2. 节点的插入采用插入排序的算法
      * @param  _node   ： 子节点
      * @param  _zOrder ： z轴序列
      * @param  tag     ： 标识符
      * @return void    返回类型
     */
    public void addChild(CCNode _node,int _zOrder,int tag)
　　public void addChild(CCNode _node,int _zOrder)
　　public void addChild(CCNode _node)

在添加节点的时候，为了保证添加的zOrder序列都在对应的位置，我们在每次添加节点的时候，都进行一次排序

      /**
      * sortChildrens(排序所有节点)
      * @Title: sortChildrens
      * @Description: TODO
     */
    public void insertSortChildrens(CCNode node)
    {
        int len = m_vChildren.size();
        if(len == 0)
        {
            m_vChildren.addElement(node);
            return;
        }

        //倒插排序法
        for(int i = len-1;i >= 0;i--)
        {
            if(node.getZOrder() >= ((CCNode)m_vChildren.elementAt(i)).getZOrder())
            {
                m_vChildren.insertElementAt(node, i+1);
                return;
            }
        }
    }
