In this article, I've run through the design of a library for processing command line arguments as an example of reflection in action.
在本文中,我讲述了一个用于处理命令行参数的库的设计过程,作为反射的一个实际的例子。
This month I'm going even further by looking at an application that seems to be a good match for reflection's strengths and weaknesses: a library for command line argument processing.
在本月这一期的文章中,我将通过查看一个应用程序来更深入地讨论这一问题,这个应用程序是用于命令行参数处理的一个库,它能够很好地体现反射的强项和弱点。
The standard library, that first line of code, it's not strictly necessary but any time you use a function, a tool that someone else wrote that lives in that so called library, you do need that include line as we'll see.
标准库函数--第一行代码,严格来说,不是每次都要写的,但是一旦你调用某个别人写,的函数,而这个函数又恰巧位于标准库里面,你就要像我们看到的这样,把它include进去。
