Java Language Atomic Types
Introduction
Java Atomic Types are simple mutable types that provide basic operations that are thread-safe and atomic without resorting to locking. They are intended for use in cases where locking would be a concurrency bottleneck, or where there is risk of deadlock or livelock.
Parameters
| Parameter | Description |
|---|---|
| set | Volatile set of the field |
| get | Volatile read of the field |
| lazySet | This is a store ordered operation of the field |
| compareAndSet | If the value is the expeed value then sent it to the new value |
| getAndSet | get the current value and update |
Remarks
Many on essentially combinations of volatile reads or writes and CAS operations. Best way to understand this is to look at the source code directly. E.g. AtomicInteger, Unsafe.getAndSet
