Class BasicStorable

java.lang.Object
  com.jalios.jstore.BasicStorable

All Implemented Interfaces:

Storable, Cloneable, Comparable<BasicStorable>

Direct Known Subclasses:

Data, Test

public class BasicStorable
extends Object
implements Storable, Comparable<BasicStorable>, Cloneable

This class is a convenient super class for any Storable classes. It gets and sets all (non transient) attributs by introspection. It provides getter/setter for store, cdate and mdate. It encapsulated the store id of the object.
