c++ - 我是否也仅在函数头或声明中指定异常类型？ (C++)

Question

  SVector.H:

  void pop_back() throw (underflow_error);

在我的 SVector.cpp 文件中，我是否也应该包含 throw (underflow_error) 部分？

void pop_back() throw (underflow_error)
{
    // implementation
}

或

void pop_back()
{
    // implementation
}

谢谢。

If any declaration of a function has an exception-specification, all declarations, including the definition and an explicit specialization, of that function shall have an exception-specification with the same set of type-ids.
