Class DatabaseObject

java.lang.Object
  aspoev.interpreter.base.MetaObject
      aspoev.manager.DatabaseObject

All Implemented Interfaces:

pJ.jasmine.PRI, java.io.Serializable

public class DatabaseObject

extends MetaObject

implements pJ.jasmine.PRI

This class is an object handle for the database. It enables the instance adapter to swap object representations without losing referential integrity within the database, i.e. all references that exist to an object within the database point to its object handle, and thus are not invalidated when the object changes via conversion.
