An option that refers to a packet at the end of the queue may require a full list traversal by the receiving TCP stack in order to identify which packet the option refers to. 一个指向队列末尾包的选项可能会迫使接收方的TCP协议栈遍历整个队列以判断此选项指向哪一个包。
It implements List and is thread-safe, but its iterators will not throw ConcurrentModificationException and do not require any additional locking during traversal. 它实现了List,而且是线程安全的,但是它的迭代器不会抛出ConcurrentModificationException,遍历期间也不要求额外的锁定。
In the process of modeling, getting two-way linked list to store control point data of the tree model. Then using the depth-first traversal method to traverse the two-way linked list. 在建模过程中,利用双向链表来存储树模型的控制点数据,然后采用数据结构中深度优先遍历方法,遍历出树模型中每段树枝。
