expect fun exchange(newValue: Boolean): Boolean(source)

Atomically stores the given new value into this AtomicBoolean and returns the old value.

Since Kotlin

2.1

Samples

import kotlin.concurrent.atomics.*
import kotlin.concurrent.thread

fun main() { 
   //sampleStart 
   val a = AtomicBoolean(true)
println(a.exchange(false)) // true
println(a.load()) // false 
   //sampleEnd
}
actual fun exchange(newValue: Boolean): Boolean(source)

Atomically stores the given new value into this AtomicBoolean and returns the old value.
