Using the IntDef#flag()
attribute set to true
, multiple constants can be combined.
Using the same example in this topic:
public abstract class Car {
//Define the list of accepted constants
@IntDef(flag=true, value={MICROCAR, CONVERTIBLE, SUPERCAR, MINIVAN, SUV})
//Tell the compiler not to store annotation data in the .class file
@Retention(RetentionPolicy.SOURCE)
.....
}
Users can combine the allowed constants with a flag (such as |
, &
, ^
).
