=======================================================================

因为要用到好多设计模式，所以我把原文拆成几部分，每部分讲解一个设计模式、用一个模式实现一个扩展功能。wlsandwho王林森

（这意味着还有一篇。）

=======================================================================

上一篇讲了用COMMAND模式设计事务小工具的基本骨架，传送门：C++基础——模拟事务（1）COMMAND模式

这里将继续使用Composite模式，以使事务可以嵌套。wlsandwho王林森

=======================================================================

下面该去考虑如何实现“嵌套事务”了。wlsandwho王林森

想要一个事务像一个任务一样，被添加到另一个事务里，并且能任意的组合，形成一个树形的结构，那么事务肯定要有和任务一样的接口。

好像composite模式比较合适处理这个问题。

*的典型的composite对象结构图我就不画了，composite结构图我也不画了。wlsandwho王林森

事务要想拥有任务的功能，最简单的方法是事务类继承任务类。考虑到单继承、多继承之争，我采用单继承实现。

大致结构图如下。wlsandwho王林森

如此一来，CTransactionBase有了CTaskBase的接口,就能够把一个CTransaction加到另一个CTransaction的容器里。wlsandwho王林森

回顾一下CTaskBase的两个接口函数，一个是Do，Do里执行Doing，另一个Undo，Undo里执行Undoing。Doing和Undoing是用Set函数进行手工设置绑定的。

CTransactionBase继承此接口后，Do里执行Commit，Undo里执行Rollback。Commit和Rollback是CTransactionBase的保护成员函数。这样,

把一个CTransaction加到另一个CTransaction的容器里时,不再需要额外的设置Do和Undo的动作,他们是内置的。
