|
| -// ===============================================================
|
| -// 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.

| -// How to define a type safe enum list using the EnumClass template?
|
| -// ================================================================
|
| -// Definition should be a struct that encapsulates an enum list.
|
| -// The enum list should be names Enums.
|
| -//
|
| -// Here's an example of how to define a type safe enum named MyEnum using
|
| -// the EnumClass template:
|
| -//
|
| -// struct MyEnumDefinition {
|
| -// enum Enums {
|
| -// ValueDefault,
|
| -// Value1,
|
| -// ...
|
| -// ValueN
|
| -// };
|
| -// };
|
| -// typedef EnumClass<MyEnumDefinition, MyEnumDefinition::ValueDefault> MyEnum;
|
| -//
|
| -// With that, you can now use MyEnum enum values as follow:
|
| -//
|
| -// MyEnum value1; // value1 is assigned MyEnum::ValueDefault by default.
|
| -// MyEnum value2 = MyEnum::Value1; // value2 is assigned MyEnum::Value1;
