All Implemented Interfaces:

ObjectRepository, Repository

public class CDIXMLFilePersistentObjectRepository

extends AbstractXMLFilePersistentObjectRepository

implements ObjectRepository

This is a simple implementation of persistent object store using XML serialization from JDK 1.4 to a file system. This implementation of ObjectRepository comes with the following warning: "XMLEncoder provides suitable persistence delegates for all public subclasses of java.awt.Component in J2SE and the types of all of their properties, recursively. All other classes will be handled with the default persistence delegate which assumes the class follows the beans conventions" (snipped from the BugParade) Basically, don't use this block for anything other than Swing component serialization. Sun will have to do a lot of work writing a "PersistenceDelegate" to handle other JDK types let alone custom classes.
