enum class..enum class转整型最安全的做法就是使用std::to_underlying,虽然这玩意C++23才有,但自己写一个也是很简单的。就你期望的用法而言,可以参考标准库future中std::lau
原因1.大括号不匹配
When this happens, the enumerator object is no longer synchronized with the pin, and the class methods return VFW_E_ENUM_OUT_OF_SYNC. Call the CEnumMediaTypes::Reset method to resynchronize the enumerator.Expand table Public MethodsDescription CEnumMediaTypes Constructor method. ~CEnumMedia...
1、实现方法 在开发中遇到的一个场景,需要自动生成enum class,并且还要有enum与string相互转换函数,当需要扩展enum class的时候,只需要在初始化的时候改动 enum class,不需要改动enum与string相互转换函数,转换函数都是根据enum自动生成。 github tool/enum_class at main · C-CX/toolgithub.com/C-CX/tool/tr...

For this reason, the base classes provide generic functions (not member functions of a class) to create and delete media types: CreateMediaType and DeleteMediaType. These manage memory allocation from the task allocator.All member functions in this class that return HRESULT and accept a pointer ...

Enter strongly typed enums--and I don't mean enums. Strongly typed enums are a new kind of enum, declared like so:1 2 3 // this code will compile (if your compiler supports C++11 strongly typed enums) enum class Color {RED, GREEN, BLUE}; enum class Feelings {EXCITED, MOODY, ...
1) C++98 的 enum是“非域内的”;而 C++11 的 enum class是“域内的”,限制了枚举成员只在域内可见 2) enum class 的缺省潜在类型 (underlying type) 是 int 型,而 enum 没有缺省潜在类型 3) enum class一般总是前置声明,而 enum 只有在指定了潜在类型时才可以是前置声明 参考资料 《Effective Modern ...
