Any enum included in a Config is automatically validated, but much like booleans making ValidatedEnums may be useful for constructing other validation types.

public enum MyEnum {
    A,
    B,
    C
}

public MyEnum simpleEnum = MyEnum.A; //this will work most of the time
public ValidatedEnum<MyEnum> validatedEnum = new ValidatedEnum(MyEnum.A, ValidatedEnum.WidgetType.CYCLING); //ValidatedEnum can be used to customize the GUI appearance

Translation

Enums can implement a special interface EnumTranslatable that allows for translation of enum constants and custom tooltips per constant. See Translation for details.
