enum Type

Handling enum Types

An enum type is a collection of named constants.

It is distinguished from int type but internally holds integer values.

When declared without specifying values, 0, 1, 2... are assigned from the beginning.

enum MyEnum {
    Apple,
    Orange,
    Banana
}
// MyEnum.Apple = 0, MyEnum.Orange = 1, MyEnum.Banana = 2

You can specify values. Subsequent values increase by 1 from there.

enum MyEnum2 {
    Dog = 10,
    Cat,
    Mouse
}
// MyEnum2.Dog = 10, MyEnum2.Cat = 11, MyEnum2.Mouse = 12

For %d in format strings, it behaves as an int type.

"%d" % MyEnum.Banana // = "2"

enum types can be cast to int type.

int(MyEnum.Banana) // = 2

int type values can be cast to enum type.

MyEnum(1) // = MyEnum.Orange
