Class Microtype<T>

java.lang.Object

javafixes.object.Microtype<T>

Type Parameters:

T - type of wrapped value

All Implemented Interfaces:

Value<T>

public abstract class Microtype<T>
extends java.lang.Object
implements Value<T>

An immutable object that contains a non-null reference to another object.

It implements equals(), hashCode() and toString() methods

Main purpose of this class is to be able to wrap simple types and add them a class name, to make the code more readable. So instead of using String you could use AccountNumber that extends Microtype<String> or instead of BigDecimal you could use a Salary that extends Microtype<BigDecimal>.
