C ++异常规范替换 [英] C++ exception specification replacement

问题描述

经过一番阅读，我意识到在C ++中，异常规范被认为是一件坏事：

I have realized, after some reading, that in C++ the exceptions specification is considered a bad thing:

int f() throw(A, B);  // bad because a lot of reasons

（某些引用： 1 ， 2 等）

我不了解的是如何替换它。如何告诉 f（）的呼叫者他必须捕获异常？

What I have not understood is how to replace it. How can I tell to the f()'s caller that he must catch an exception?

推荐答案

怎么样

 //throws: A if something is wrong
 //        B if something else is wrong
 int f();
