sorry guys, I was tired when I posted anyMatch was a typo, I meant all { } and allMatch { } @kevinmost @arocnies

[Dalinar]

fun main(args: Array<String>) {

    val x = emptyMap<String,String>()

    println(x.values.all { false })
    println(x.values.all { true })
    println(x.values.all { it.equals("nothing") })

    println(x.values.stream().allMatch( { false }))
    println(x.values.stream().allMatch( { true }))

}

true
true
true
true
true

Process finished with exit code 0

@kevinmost I guess I see your point, just wish there was something similar that returned false on 0 elements that I could use. Is there? or do I need to roll my own extension fun?

There isn't, you'll have to work around it

val allMatch = list.takeIf { it.isNotEmpty }?.all { cond } ?: false

val allMatch = list.isNotEmpty && list.all { cond }
