@Enum

The @Enum Annotation is used to define a parameter as an Enum value in the execution method of a command. Enums are a special case in terms of usage. They need to be registered using the CommandArgumentRegistrationEvent.

CommandArgumentRegistrationEvent.EVENT.register(registry -> {
    registry.registerEnum(TestEnum.class);
});

after registering the enum you can use it in your command execution method.

@Execute
public boolean example(@Enum(TestEnum.class) TestEnum _enum) {
    return true;
}
