 public  void addPropertyChangeListener(PropertyChangeListener listener)
Add a property change listener to this component.

 public Session createEmptySession()
Get a session from the recycled ones or create a new empty one.
The PersistentManager manager does not need to create session data
because it reads it from the Store.

 public Session createSession()
Construct and return a new session object, based on the default
settings specified by this Manager's properties. The session

Construct and return a new session object, based on the default
settings specified by this Manager's properties, using the specified
session id.

specified session id (if any); otherwise return null.

 public Session findSession(String id,
    String version) throws IOException
Finds and returns the session with the given id that also satisfies
the given version requirement.

isSessionVersioningSupported() returns true. By default, this method
delegates to the version of findSession() that does not take any
session version number.

alive.

 public boolean isSessionVersioningSupported()
Returns true if this session manager supports session versioning, false
otherwise.

 public  void load() throws IOException, ClassNotFoundException
