Hi, Im trying out Apollo3 for my Android GraphQL client calls

[Tower Guidev2]

Apollo3 has this sealed class for warpping Optional values...

sealed class Optional<out V> {
  fun getOrNull() = (this as? Present)?.value
  fun getOrThrow() = getOrNull() ?: throw MissingValueException()

  data class Present<V>(val value: V) : Optional<V>()
  object Absent : Optional<Nothing>()

  fun <V : Any> presentIfNotNull(value: V?): Optional<V> = if (value == null) Absent else Present(value)
}

I can successfully employ Present,

FilterEpisode(name = Optional.Present(value = "in"))

however I cannot use the function presentIfNotNull

[Tower Guidev2]

how do I refer to this function?

Hi 👋

[mbonnin]

What Optional are you importing?

[Tower Guidev2]

👋

import com.apollographql.apollo3.api.Optional

[mbonnin]

Yikes, just checking this out, looks like presentIfNotNull is an instance function not static 🤦‍♂️

[mbonnin]

I'll fix this

Yep 😬

[mbonnin]

Thanks for the heads up!

I feel part of the team 😉

FWIW, we also have #apollo-android here for specific questions

[Tower Guidev2]

nice, I'll use that next time 😄
