Builds instance of session based on passed SessionData.

Specified by:

build in interface SessionFactory

Parameters:

sessionData - the descriptor of the session to build

a new instance of RepositoryBackedSession

wrapSession

protected RepositoryBackedSession wrapSession(RepositoryBackedSession oldSession)

Wraps old session object into a new one. This method can be overridden in a subclass to provide wrapping of sessions in different implementations (e.g. HttpSession).

Parameters:

oldSession - session to wrap

Returns:

wrapped session

newSessionObject

protected RepositoryBackedSession newSessionObject(SessionData sessionData)

Creates new memory representation of session based on session data.

Parameters:

sessionData - the session descriptor

Returns:

local facade to session

committed

public void committed(RepositoryBackedSession session)

Called by each session when it is committed. Used when local cache is active. This insures that when last concurrent call has been terminated, session is evicted from cache.

Specified by:

committed in interface SessionFactory

Parameters:

session - the session being committed

sessionIdChange

public void sessionIdChange(SessionData sessionData)

Description copied from interface: SessionFactory

Called by session manager to notify session factory that session id has changed. It is up to session factory to implement any needed logic. E.g. if it uses cache it can rename it here.

Specified by:

sessionIdChange in interface SessionFactory

Parameters:

sessionData - the descriptor of the session whose id changes
