We use CDynamicAccessor which inherits from CAccessorBase .我们使用继承自CAccessorBase的CDynamicAccessor 。 The function MoveNext would throw function MoveNext会抛出

HRESULT MoveNext() throw()

but without telling what exception type it is.但没有说明它是什么异常类型。 How do I know it?我怎么知道的？

1 个解决方案

No, throw() means the function is declared not to throw any exceptions.不， throw()意味着 function 被声明为不抛出任何异常。

Note that it's deprecated (and removed in C++20);请注意，它已被弃用（并在 C++20 中删除）； we can use noexcept (or noexcept(true) ) since C++11.自 C++11 以来，我们可以使用noexcept （或noexcept(true) ）。
