如何捕获初始化列表中的异常？ [英] How to catch the exception in initialization list?

问题描述

我有一个关于如何在初始化列表中捕获异常的问题。

I have a question about how to catch the exception in the initialization list.

例如，我们有一个来自Bar

For example, we have a class Foo derived from Bar

class Foo {

public:
Foo(int i) {throw 0; }

}

class Bar : public Foo{

public:

Bar() : Foo(1) {}

}

推荐答案

我认为语法是像这（即使最好在调用者中捕获这样的东西，你要去什么）

I think the syntax is like this (even though it's better to catch such things in the caller. And what are you going to do once you caught it?)

Bar::Bar()
try
  : Foo(1)
{
}
catch( const SomeException &e )
{
}
