typedef typename __type_traits<T>::has_trivial_destructor trivial_destructor; 虽说已经有多年C++经验,但上面这短短一行代码却看得我头皮发麻。看起来它应该是定义一个类型别名,但是typedef不应该是像这样使用么,typedef+原类型名+新类型名: typedef char* PCHAR; ...
1.1 使用type traits识别枚举类型 C++ 的标准库<type_traits>提供了一系列工具,用于编译时检查类型特性。std::is_enum<T>可以用来检查一个类型是否为枚举类型。然而,这个特性并不区分强枚举和弱枚举。 1.1.1 使用std::is_enum_v std::is_enum_v<T>是std::is_enum<T>::value的简写形式。如果T是枚举类型...
