This event is the last thing to run in the constructor of the class that the user code is running in. 此事件是在运行用户代码的类的构造函数中运行的最后一个事件。
In my experience, these functions are needed only rarely in entry actions so this workaround should not uglify user code too much. 以我的经验，在进入动作中很少需要这些函数，所以这一方法不会使得用户代码太过难看。
