# Atomic*工具类
|
||
|
||
## AtomicBoolean
|
||
|
||
### 1. 成员变量
|
||
|
||
```java
|
||
// 对应的类中的成员变量句柄
|
||
private static final VarHandle VALUE;
|
||
// 存储变量的值
|
||
private volatile int value;
|
||
```
|
||
|
||
### 2. 核心
|
||
|
||
set时使用句柄（VarHandle）来进行设置value，获取时使用value进行获取
|
||
|
||
## AtomicInteger
|
||
|
||
### 1. 成员变量
|
||
|
||
```java
|
||
private static final Unsafe U = Unsafe.getUnsafe();
|
||
private static final long VALUE = U.objectFieldOffset(AtomicInteger.class, "value");
|
||
private volatile int value;
|
||
```
|
||
|
||
### 2.核心
|
||
|
||
与Boolean类似
|
||
|
||
## AtomicLong
|
||
|
||
### 1. 成员变量
|
||
|
||
```java
|
||
|
||
```
|
||
|
||
# Atomic*Array工具类
|
||
|
||
## AtomicIntegerArray
|
||
|
||
### 1. 成员变量
|
||
|
||
```java
|
||
private static final VarHandle AA = MethodHandles.arrayElementVarHandle(int[].class);
|
||
private final int[] array;
|
||
```
