fs.watchFile('message.text', function (curr, prev) { console.log('the current mtime is: ' + curr.mtime); console.log('the previous mtime was: ' + prev.mtime); }); listener中的文件状态对象类型为fs.Stat。 如果想修改文件时被通知,而不是访问的时候就通知,可以比较curr.mtime和prev.mtime。
首先,将变量prev向后移动一个位置,指向待删除结点的前一个结点。 接着,执行语句prev.next=delNode.next,即将变量prev所指向结点的后继指针next指向待删除结点的下一个结点,如下图: 最后,执行delNode.next=null就可将待删除结点从链表中释放,如下图: 删除链表指定位置结点时间复杂度分析: 如果是删除头结点,则虚...
node.prev = last; } last = node; }3.2.3 从头部删除结点 判断头结点是否有下一个结点,如果没有则设置尾结点为null,否则设置头结点的下一个结点的prev为null。复杂度也为O(1)。 public Node deleteFirst(){ Node tmp = first; if(first.next == null){ ...
