严格来讲，一个对象既是普通类型（Trivial Type）又是标准布局类型（Standard-layout Type）那么这个对象就是POD类型。...下面我们使用模版类std::is_trivial::value来判断数据类型是否为普通类型。...std::is_trivial::value; //有自定义的移动构造运算符 std::cout ::value; //有自定义的赋值运算符...std::cout ::value; //有自定义的移动赋值运算符 std::cout ::value...; //有自定义的析构函数 std::cout ::value; //有虚函数 std::cout << std::is_trivial<H
如果我们不清楚POD的判断标准的话，只能靠猜来回答该问题，幸运的是Modern Cpp提供了接口来进行判断(PS:下面的trivial和standard layout用来辅助判断)： C++11 C++...17 描述 std::is_pod std::is_pod_v 通过其value是否为ture来表示是否为POD类型(std::is_pod::value) std::is_trivial std::is_trivial_v...Trivial 这个概念比较抽象，乃至于很难用一句简单的话来描述。...也就是说，当一个类型（class/struct ）同时满足以下几个条件时，它就是 trivial type： • 没有虚函数或虚基类。...true std::cout ::value << std::endl; // print true std::cout << std::is_trivial
