Atomic.Integer (mapdb 3.0.7 API)

java.lang.Object
- java.lang.Number
- - org.mapdb.Atomic.Integer

All Implemented Interfaces:

java.io.Serializable

Enclosing class:

Atomic
```
public static final class Atomic.Integer
extends java.lang.Number
```
An int record that may be updated atomically. An Atomic@Integer is used in applications such as atomically incremented counters, and cannot be used as a replacement for an Integer. However, this class does extend Number to allow uniform access by tools and utilities that deal with numerically-based classes.

  - set
```
public final void set(int newValue)
```
    Sets to the given value.
    
    Parameters:
    
    newValue - the new value
  - getAndSet
```
public final int getAndSet(int newValue)
```
    Atomically sets to the given value and returns the old value.
    
    Parameters:
    
    newValue - the new value
