// How to define a type safe enum list using the ENUM_CLASS macros?
|
|
// ===============================================================
|
|
// To get an enum list like this:
|
|
//
|
|
// enum class MyEnums {
|
|
// Value1,
|
|
// Value2,
|
|
// ...
|
|
// ValueN
|
|
// };
|
|
//
|
|
// ... write this:
|
|
//
|
|
// ENUM_CLASS(MyEnums) {
|
|
// Value1,
|
|
// Value2,
|
|
// ...
|
|
// ValueN
|
|
// } ENUM_CLASS_END(MyEnums);
|
|
//
|
|
// The ENUM_CLASS macros will use C++11's enum class if the compiler supports
|
|
// it. Otherwise, it will use the EnumClass template below.
|
|
|
|
#define ENUM_CLASS(__enumName) enum class __enumName
|
|
|
|
#define ENUM_CLASS_END(__enumName)
