MutableByte (Apache Commons Lang 3.19.0 API)

java.lang.Object
- java.lang.Number
- - org.apache.commons.lang3.mutable.MutableByte

All Implemented Interfaces:

Serializable, Comparable<MutableByte>, Supplier<Number>, Mutable<Number>
```
public class MutableByte
extends Number
implements Comparable<MutableByte>, Mutable<Number>
```
A mutable byte wrapper.
This class was created before the introduction of the the java.util.concurrent.atomic package and the AtomicInteger class.

Note that as MutableByte does not extend Byte, it is not treated by String.format as a Byte parameter.

Since:

2.1
