接口实现 [英] Interface implementation
问题描述
大家好。我对接口实现有一些疑问，如果
任何人都可以帮助我，我会非常感谢。
所以：
如果我有一些接口IA：
class IA
{
virtual void SomePureVirtFunc（）= 0;
};
和一些B类，实现了该界面：
B级：公共IA
{
虚拟空虚SomePureVirtFunc（）{};
};
现在我需要在C类继承自接口ITwoInOne，从IA继承了
。
问题：这是任何方法，继承自ITwoInOne接口，并且
不要实现接口IA，但是使用多继承 - 从B类继承
，已经实现了该接口，并满足我的
要求？
换句话说：我能写出类似的东西：
class NewOne：public B
，public ITwoInOne
{
//仅实现纯虚函数
//，不对应IA接口
}
P.S.抱歉混淆，以及我的英语不好。
Hi all. I have some questions about interface implementation, if
anybody can help me, I will be very thank.
So:
If i have some interface IA:
class IA
{
virtual void SomePureVirtFunc() = 0;
};
and some class B, that implemented that interface:
class B : public IA
{
virtual void SomePureVirtFunc() {};
};
Now I need in class C inherit from interface ITwoInOne, that inherited
from IA also.
Question: it is any method, inherit from interface ITwoInOne, and
don''t implement interface IA, but using multiple inheritance - inherit
from class B, that already implemented that interface, and satisfy my
requirements?
Another words: can I write something like that:
class NewOne : public B
, public ITwoInOne
{
//Implementation only pure virtual functions
//, that not correspond to IA interface
}
P.S. sorry for confusion, and for my bad English.

是的，从IA _virtually_ *继承*。即虚拟地使B继承自
IA并使ITwoInOne虚拟继承。
Yes, inherit from IA _virtually_ *everywhere*. I.e. make B inherit from
IA virtually and make ITwoInOne inherit virtually.

另一个词：can我写的是这样的：
class NewOne：public B
，public ITwoInOne
{
//仅实现纯虚函数
//，不对应IA接口
}
PS对不起困惑，我的英语不好。

是的，继承IA _virtually_ *到处*。即使B继承自
Yes, inherit from IA _virtually_ *everywhere*. I.e. make B inherit from
IA虚拟化并使ITwoInOne虚拟继承。
IA virtually and make ITwoInOne inherit virtually.
所以这是正确的方式：
B级：公共虚拟IA
{< br $>
};
类NewOne：公共虚拟B
，公共虚拟ITwoInOne
{
};
这是对的吗？
如果是，那么问题：是课程的顺序继承是否重要？
我的意思是，如果我先写公共虚拟ITwoInOne，而不是
" public virtual B"
So this is right way:
class B : public virtual IA
{
};
class NewOne : public virtual B
, public virtual ITwoInOne
{
};
Is this right?
If yes, than question: is order of classes for inheritance important?
I mean it is OK if I write first "public virtual ITwoInOne", and than
"public virtual B"?

我认为订单并不重要。你试过吗？如果你有
，并且成功取决于订单，请你分享一下吗？
如果你还没试过，为什么？

I think that the order is not significant. Have you tried it? If you
have, and the success depended on the order, could you please share?
If you haven''t tried, why?
