fun AtomicIntArray.fetchAndIncrementAt(index: Int): Int(source)

Atomically increments the element of this AtomicIntArray at the given index by one and returns the old value of the element.

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))
println(a.fetchAndIncrementAt(1)) // 2
println(a.loadAt(1)) // 3
println(a.toString()) // [1, 3, 3] 
   //sampleEnd
}
xxxxxxxxxx
 
val a = AtomicIntArray(intArrayOf(1, 2, 3))
println(a.fetchAndIncrementAt(1)) // 2
println(a.loadAt(1)) // 3
println(a.toString()) // [1, 3, 3]
