fetchAndAddAt

expect fun fetchAndAddAt(index: Int, delta: Int): Int(source)

Atomically adds the given delta to the element of this AtomicIntArray at the given index and returns the old value of the element.

Since Kotlin

2.1

Throws

IndexOutOfBoundsException

if the index is out of bounds of this array.

Samples

import kotlin.concurrent.atomics.*

fun main() { 
   //sampleStart 
   val a = AtomicIntArray(intArrayOf(1, 2, 3))
// Returns the old value before the addition.
println(a.fetchAndAddAt(1, 10)) // 2
println(a.loadAt(1)) // 12
println(a.toString()) // [1, 12, 3] 
   //sampleEnd
}
