AtomicLong
A Long value that is always updated atomically. For additional details about atomicity guarantees for reads and writes see kotlin.concurrent.Volatile.
Legacy MM: Atomic values and freezing: this type is unique with regard to freezing. Namely, it provides mutating operations, while can participate in frozen subgraphs. So shared frozen objects can have mutable fields of AtomicLong type.

addAndGet
Atomically adds the given value to the current value and returns the new value.
fun addAndGet(delta: Long): Longfun addAndGet(delta: Int): LongcompareAndSet
Atomically sets the value to the given new value if the current value equals the expected value, returns true if the operation was successful and false only if the current value was not equal to the expected value.
fun compareAndSet(expected: Long, newValue: Long): BooleancompareAndSwap
Atomically sets the value to the given new value if the current value equals the expected value and returns the old value in any case.
fun compareAndSwap(expected: Long, newValue: Long): Longdecrement
Atomically decrements the current value by one.
fun decrement()decrementAndGet
Atomically decrements the current value by one and returns the new value.
fun decrementAndGet(): LonggetAndAdd
Atomically adds the given value to the current value and returns the old value.
fun getAndAdd(delta: Long): LonggetAndDecrement
Atomically decrements the current value by one and returns the old value.
fun getAndDecrement(): LonggetAndIncrement
Atomically increments the current value by one and returns the old value.
fun getAndIncrement(): LonggetAndSet
Atomically sets the value to the given new value and returns the old value.
fun getAndSet(newValue: Long): Longincrement
Atomically increments the current value by one.
fun increment()incrementAndGet
Atomically increments the current value by one and returns the new value.
fun incrementAndGet(): LongtoString
Returns the string representation of this object.
