MutableByte (Lang 3.4)

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

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<MutableByte>, Mutable<java.lang.Number>
```
public class MutableByte
extends java.lang.Number
implements java.lang.Comparable<MutableByte>, Mutable<java.lang.Number>
```
A mutable byte wrapper.
Note that as MutableByte does not extend Byte, it is not treated by String.format as a Byte parameter.
