### Forward list ###

前向链表是序列容器，使固定时间插入和擦除操作序列内的任何地方。

前向链表的实现方式和单链表相同；单链表可以存储所包含的每个元素在不同的和无关的存储位置。

在序列中顺序保存每个元素指向下一个元素的关联。

forward\_list容器与list容器的主要设计区别是list保持内部唯一的一个链接到下一个元素，而后者则保持每个元素的两个链接：一个指向下一个元素和一个前一个。允许高效在两个方向迭代，但每个元素的消耗额外的存储空间，并轻微较高的时间开销插入和删除元素的迭代。forward\_list对象，从而比list对象更有效率，虽然他们只能向前遍历。

与其他的基本标准序列容器（array，vector和deque）相比，forward\_list一般在容器内的任何位置中的元素的插入、提取和移动操作效率更高，因此在算法中较密集的使用这些操作，例如排序算法。

相比其他序列容器，forward\_lists的主要缺点是缺乏直接访问他们的位置的元素，例如，要进入第六个元素在forward\_list的一个遍历从一开始就到那个位置，这需要线性时间之间的距离。他们也消耗了一些额外的内存保持连接信息相关联的每个元素（这可能是一个小型的元素的大链表的重要因素）。

考虑到forward\_list类模板设计的性能:根据设计，它是作为一个简单的手写C风格的单链表一样高效，实际上是仅有的一个标准容器故意缺乏其大小的成员函数是出于效率的考虑。由于其作为一个链表的性质，有一个大小成员在固定的时间，需要保持一个内部的计数器保存其大小（和链表一样）。这会消耗一些额外的存储和使插入和删除操作，效率较低。为了获得一个forward\_list对象的大小，可以用其开始和结束，这是一个线性时间的操作距离算法。

### 容器属性 ###

##### 序列 #####

在一个严格的线性序列中序列容器的元素是有序的。个别元素的访问是通过他们在这个序列中的位置。

### 链表 ###

每个元素保持如何找到下一个元素的信息，允许常量时间在特定元素（甚至整个范围）后进行插入和擦除操作，但没有直接随机存取。

### 分配器的获取 ###

容器使用一个分配器对象动态地处理其存储需求。
