术语“异常强”和“异常中性”意思？ [英] What the terms "exception strong" and "exception neutral" mean?

问题描述

我认为 exception strong 意味着程序可以成功结束，或者如果它没有成功结束，它将保留数据不变，但我不知道什么异常中立表示。有人可以定义这两个术语吗？

I think exception strong means that the program either ends successfully or if it doesn't ends successfully it leaves the data unchanged, but I am not sure what exception neutral means. Can someone define these two terms?

推荐答案

从常规组件中的异常安全：

强有力的保证：操作已成功完成或抛出异常，使程序状态与操作开始之前完全一致。

The strong guarantee: that the operation has either completed successfully or thrown an exception, leaving the program state exactly as it was before the operation started.

和

and

在一个通用组件中，我们通常会有一个额外的异常中立期望，这意味着应该传播一个组件的类型参数抛出的异常，不变，对组件的呼叫者。

In a generic component, we usually have an additional expectation of exception-neutrality, which means that exceptions thrown by a component's type parameters should be propagated, unchanged, to the component's caller.
