The machine dutifully makes the transitions we would expect, but no actions are executed yet. 这个状态机将忠实地按我们的期望进行状态的转换,不过仍然没有动作被执行。
If, for example, you ask the inventory query system to tell you how many widgets are in stock , it will dutifully ask the database and report the number as of the time you ask. 例如,如果你请库存查询系统告诉你还有多少小部件,它会忠实地查询数据库,并报告到你提问时间为止的库存数量。
