MutableLong (Apache Commons Lang 3.19.0 API)

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

All Implemented Interfaces:

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

Note that as MutableLong does not extend Long, it is not treated by String.format(String, Object...) as a Long parameter.

Since:

2.1
