Class ObjectStreamPersistenceManager

java.lang.Object
  org.jboss.mx.persistence.ObjectStreamPersistenceManager

All Implemented Interfaces:: PersistenceManager

public class ObjectStreamPersistenceManager
extends Object
implements PersistenceManager

Object Stream Persistence Manager.

Persists the MBean to the file system using an Object Stream. Includes code based on examples in Juha's JMX Book.

Object Streams written to disk are admittedly lacking in the area of "long-term", "portable", or "human-readable" persistence. They are fairly straightforward, however. Primarily, this class is useful for demonstration and "quick & dirty" persistence.
