/**
*
* Immutable is a root interface of immutable classes; i.e.,
* those with objects that may be looked at but not updated.
* By necessity in Java, all implementation classes supporting
* interface Immutable must be <CODE>final</CODE> classes.
* <P>
* There are
* no operations defined in this interface. This interface is used only
* to provide a name for this `Purity' property.
* @author Doug Lea
* @version 0.93
