public abstract class Value
extends java.lang.Object

A Value is an object that holds an internal (but public) variable. This abstract class provides a unified way of acessing the variable value. The fact the variable is public permits quick access to it.

When using subclasses, it is a good idea to directly access the internal variable or use the correct 'get' method in order to increase speed.

Using Number is not suitable for two reasons:

Number does not include Strings and Objects

Number does not allow direct access to the internal variable
