AtomicReference原子性引用浅析（持续更新）
目录
一、前言
- AtomicReference原子性引用，一般情况下用不到，更多的是在使用多线程操作修改数据时会用到
- Java文档描述为：An object reference that may be updated atomically.（一个可以被原子性更新的对象引用）
二、方法说明
| 返回值 | 方法名 | 英文描述 | 中文描述 |
|---|---|---|---|
| final V | accumulateAndGet(V x, BinaryOperator<V> accumulatorFunction) |
Atomically updates the current value with the results of applying the given function to the current and given values, returning the updated value. | 通过当前值和给定的值来原子性的更新当前值，返回更新后的值 |
| final boolean | compareAndSet(V expect, V update) |
Atomically sets the value to the given updated value if the current value == the expected value. |
如果当前值等于给定的值，则原子性地设置新的值 |
| final V | get() | Gets the current value | 获得当前值 |
| final V | getAndAccumulate(V x,BinaryOperator<V> accumulatorFunction) |
Atomically updates the current value with the results of applying the given function to the current and given values, returning the previous value. | 通过当前值和给定的值来原子性的更新当前值，返回更新前的值 |
| final V | getAndSet(V newValue) |
Atomically sets to the given value and returns the old value. | 原子性地设置给予的值并返回更新前的值 |
| final V | getAndUpdate(UnaryOperator<V> updateDunction) |
Atomically updates the current value with the results of applying the given function, returning the previous value. | 根据给定的值原子性地更新当前值，返回更新前的值 |
| final void | lazySet(V newValue) |
Eventually sets to the given value. | 最终设置为给予的值 |
| final void | set(V newValue) |
Sets to the give value | 设置为给予的值 |
| final V | updateAndGet(UnaryOperator<V> updateFunction) |
Atomically updates the current value with the results of applying the given function, returning the updated value. | 根据给定的值原子性地更新当前值，返回更新后的值 |
| final boolean | weakCompareAndSet(V expect,V update) |
Atomically sets the value to the given updated value if the current value == the expected value. |
如果当前值等于给定的值，则原子性的设置更新值 |
