var objectMapper: ObjectMapper = {
            val mapper = ObjectMapper()
            mapper.registerModules(JavaTimeModule(), KotlinModule())
            mapper.disable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS)
            mapper.setSerializationInclusion(JsonInclude.Include.NON_NULL)
            mapper
        }

is there a way to do an initialization block kind of like this? just init? is there something more per property?

Just add () to the end to execute immediately.

val objectMapper: ObjectMapper = ObjectMapper().apply {
  registerModules(JavaTimeModule(), KotlinModule())
  disable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS)
  setSerializationInclusion(JsonInclude.Include.NON_NULL)
        }

@streetsofboston 🙈

[Marc Knaup]

☝️ That would be more idiomatic Kotlin 🙂

[Marc Knaup]

Pere has val and Anton has omitted the redundant variable type.
+1 for both, still a tie 😄

[Pere Casafont]

@xenoterracide also please prefer to use val everywhere you can and var only when you really need to be able to alter its value in the future. In your use case var smells a bit 😉

[xenoterracide]

@Pere Casafont yeah I am, in this case this is going in a builder so the final thing can be immutable 😉

[Pere Casafont]

awesome!

[Marc Knaup]

The variable will be immutable, not the object it refers to 🙂

[xenoterracide]

of course

[xenoterracide]

still

[xenoterracide]

anyways, thanks guys
