I have the following code ```data class SquadEntry val name String var leader OptionalPresence lt UUID gt = OptionalPresence empty var color OptionalPresence lt String gt = OptionalPresence empty var tag OptionalPresence lt String gt = OptionalPresence empty var members OptionalPresence lt Set lt UUID gt gt ``` Every time I want to write to a field e g leader I have to do leader = OptionalPresence value Is there a way to use something like delegate properties to simplify this process

data class SquadEntry(
        val name: String,
        var leader: OptionalPresence<UUID> = OptionalPresence.empty(),
        var color: OptionalPresence<String> = OptionalPresence.empty(),
        var tag: OptionalPresence<String> = OptionalPresence.empty(),
        var members: OptionalPresence<Set<UUID>>
)

Every time I want to write to a field e.g. leader I have to do leader = OptionalPresence(value). Is there a way to use something like delegate properties to simplify this process?

Delegate doesnt let you set a different type than the field

but even if it allowed you would lose the 3 states you are trying to track

or nor.. if you could create 2 different setters, onr for thr primitive associated with OptionalPresence and other for OptionalPresence

you should rethink the way your dao handle things
