Effective Modern C++ 主要讲述了 C++11/14 新特性的用法,阐述从两方面展开,一是原理解析,二是注意事项。如 auto 的原理使用的是模板推断机制,进而介绍模板的推断机制,再由此引出 auto 在使用上应该注意的问题。不同读者在这本书中可以各取所需,如果希望了解 C++11/14 的方方面面,则可以抽丝剥茧地深究原理,如果希望短时间内快速上手 C++11/14 工程实践,则只需略读原理但牢记结论,使用时绕开易产生问题的用法即可。此为个人笔记,条款非直译,而是个人理解的更贴近作者意图的表述。.

QUESTION
Reference: Effective Modern C++ Item 4.
...ANSWER
Answered 2017-Jan-07 at 02:34Question> Why the real type of param is Widget const * const & instead?
I'm not really an expert but... because T
is a pointer and if you write const T &
(that is T const &
because the rule is that const
apply on the element on the left or on the element on the right in there isn't an element on the left) you are imposing that the full T
type, so the pointer, is constant.
And to impose that the pointer is constant, you have to impose cont
on the left of the *
.
In brief: const T &
is equivalent to T const &
; with T
that is const Widget *
, T const &
become const Widget * const &
or, if you prefer, Widget const * const &
