Class AtomicLongArray

java.lang.Object

dev.gmitch215.bytebox.locks.AtomicLongArray

public class AtomicLongArray
extends Object

java.util.concurrent.atomic.AtomicLongArray, which the class library does not carry even though it carries AtomicLong.

Indivisible for the same reason as AtomicReferenceArray: one fiber runs at a time and none of these operations suspends, so no two of them interleave.

Since:

1.0.2
