Kotlin equivalent of Scala Traversable.collect

Question

Is there an equivalent in Kotlin for Scala's Traversable.collect function?

Specifically, I would like to map a List to a List, but only if that can succeed.

myList.map {
  val myNullableThing = it.someNullableMethod()
  // If it is null, then I cannot continue here
  // and I want to simply ignore this item
}

Although less generalized than the Scala collect function, mapNotNull should work in your case: https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.collections/map-not-null.html
