user code的用法和樣例：
例句
- This event is the last thing to run in the constructor of the class that the user code is running in.
此事件是在運行用戶代碼的類的構造函數中運行的最後一個事件。 - In my experience, these functions are needed only rarely in entry actions so this workaround should not uglify user code too much.
以我的經驗，在進入動作中很少需要這些函數，所以這一方法不會使得用戶代碼太過難看。
