do-nothing function

基本解释

A do-nothing function like this is sometimes useful as a place holder during program development.
这种不执行任何操作的函数有时很有用，它可以在程序开发期间用以保留位置。
If nothing has changed -- or, more likely, you have no tests for the function that has changed -- you simply do not run anything!
如果没什么发生变更 —— 或者，更可能的是，您没有对发生变更的功能进行测试 —— 您只是不运行任何东西！
Once the function returns a value outside that range, either the value is passed to a different handler or the state machine exits after calling a do-nothing end-state handler.
一旦函数返回了超出范围的值，那么该值将传送到另一个处理程序，或者状态机在调用了一个什么也不做的终态处理程序后就退出。

Moreover, nothing the Arabs or any other non-Western governments do is a function of their will.
