Nevermind, it can work. However the field must be nullable as well as getValue return value. A workaround is to create two implementations a

OptionalPresence

and

OptionalNullablePresence

Delegation isnt an option for me. I need to find out whether a field is present or not. Delegate properties don't offer the ability to access the delegate class's members. The alternative solution is to try-catch every get operation, but that sounds terrible. I'll stick to an java Optional style implementation
