Class XMLFilePersistentObjectRepository
java.lang.Object
org.apache.avalon.framework.logger.AbstractLogEnabled
org.apache.avalon.cornerstone.blocks.masterstore.AbstractFileRepository
org.apache.avalon.cornerstone.blocks.masterstore.xml.XMLFilePersistentObjectRepository
- All Implemented Interfaces:
- Configurable, Contextualizable, Initializable, LogEnabled, ObjectRepository, Repository, Serviceable
- public class XMLFilePersistentObjectRepository
- extends AbstractFileRepository
- 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.
