Google 的 C++ 风格指南 说我们不使用异常".该样式未提及有关异常使用的 STL.既然 STL 分配器可能会失败,那么它们如何处理容器抛出的异常?
Google's C++ style guide says "We do not use exceptions". The style does not mention STL with respect to usage of exception. Since STL allocators can fail, how do they handle exceptions thrown by containers?
push_back()
或 map operator[]
等 STL 方法不返回任何状态代码.push_back()
or map operator[]
do not return any status codes.他们说他们不使用异常,并不是说没有人应该使用它们.如果你看看他们还写的基本原理:
They say that they don't use exceptions, not that nobody should use them. If you look at the rationale they also write:
由于 Google 现有的大多数 C++ 代码都没有准备好处理异常,因此采用生成异常的新代码相对比较困难.
Because most existing C++ code at Google is not prepared to deal with exceptions, it is comparatively difficult to adopt new code that generates exceptions.
