Class MutableLong

java.lang.Object

java.lang.Number

dev.brachtendorf.mutable.MutableLong

All Implemented Interfaces:

Mutable<Long>, Serializable, Comparable<MutableLong>

public class MutableLong
extends Number
implements Mutable<Long>, Comparable<MutableLong>

Mutable class wrapper for long values. Mutable classes are useful in lambda expressions or anonymous classes which want to alter the content of a variable but are limited to final or effective final variables. Be aware that the hashcode changes if the value is updated resulting in the object not being retrievable in hash collections.
