A C/C++ enum [N4140 7.2]. For example, the types MyEnum and MyScopedEnum in: enum MyEnum { MyEnumConstant }; enum class MyScopedEnum { MyScopedEnumConstant }; This includes C++ scoped enums, see the ScopedEnum QL class.Import path import cpp ...
In the above example,Coloris an enum class, so we normally would access the enumerators using a fully qualified name (e.g.Color::blue). However, within functiongetColor(), we’ve added the statementusing enum Color;, which allows us to access those enumerators without theColor::prefix. ...
