I have MyComputedValue extending ValueComposite with inner class mixin
providing property implemetation:
@Mixins(MyComputedValue.MyComputedMixin.class)
public interface MyComputedValue extends ValueComposite, MyComputed {
abstract class MyComputedMixin implements MyComputed {
@Override
public Property<Integer> computedValue() {
return new ComputedPropertyInstance<Integer>(
new GenericPropertyInfo(MyComputed.class,
"computedValue")) {
@Override
public Integer get() {
return 1234;
}
};
}
}
}
