Java Source Code / Java Documentation » Web Framework » TURBINE » org.apache.turbine.services.session   Source Cross Reference   Class Diagram   Java Document (Java Doc)   org.apache.turbine.services.TurbineBaseService    org.apache.turbine.services.session.TurbineSessionService TurbineSessionService public class TurbineSessionService extends TurbineBaseService implements SessionService(Code) The SessionService allows thread-safe access to the current sessions of the current context. The session objects that are cached by this service are obtained through a listener, which must be configured via your web application's web.xml deployement descriptor as follows: <listener> <listener-class> org.apache.turbine.session.SessionListener </listener-class> </listener> author:    Quinton McCombs author:    Daniel Rall since:    2.3 version:    $Id: TurbineSessionService.java 534527 2007-05-02 16:10:59Z tv $ See Also:   org.apache.turbine.services.session.TurbineSession See Also:   org.apache.turbine.services.session.SessionListener Method Summary public  void addSession(HttpSession session)      Adds a session to the current list. public  Collection getActiveSessions()      Gets a list of the active sessions. public  Collection getActiveUsers()      Gets a collection of all user objects representing the users currently logged in. public  HttpSession getSession(String sessionId)      Gets the HttpSession by the session identifier Parameters:   sessionId - The unique session identifier. public  Collection getSessionsForUser(User user)      Get a collection of all session on which the given user is logged in. public  User getUserFromSession(HttpSession session)      Gets the User object of the the specified HttpSession. Parameters:   session - The session from which to extract a user. public  void init()      public  boolean isUserLoggedIn(User user)      Determines if a given user is currently logged in. public  void removeSession(HttpSession session)      Removes a session from the current list. public  void shutdown()      Returns to uninitialized state. Method Detail addSession public void addSession(HttpSession session)(Code) Adds a session to the current list. This method should only be called by the listener. Parameters:   session - Session to add getActiveSessions public Collection getActiveSessions()(Code) Gets a list of the active sessions. A copy of the list of HttpSession objects. getActiveUsers public Collection getActiveUsers()(Code) Gets a collection of all user objects representing the users currently logged in. This will exclude any instances of anonymous user that Turbine will use before the user actually logs on. A set of org.apache.turbine.om.security.User objects. getSession public HttpSession getSession(String sessionId)(Code) Gets the HttpSession by the session identifier Parameters:   sessionId - The unique session identifier. The session keyed by the specified identifier. getSessionsForUser public Collection getSessionsForUser(User user)(Code) Get a collection of all session on which the given user is logged in. Parameters:   user - the user Collection of HtttSession objects getUserFromSession public User getUserFromSession(HttpSession session)(Code) Gets the User object of the the specified HttpSession. Parameters:   session - The session from which to extract a user. The Turbine User object. init public void init()(Code) Initializes the service isUserLoggedIn public boolean isUserLoggedIn(User user)(Code) Determines if a given user is currently logged in. The actual implementation of the User object must implement the equals() method. By default, Torque based objects (liek TurbineUser) have an implementation of equals() that will compare the result of getPrimaryKey(). Parameters:   user - User to check for true if the user is logged in on one of theactive sessions. removeSession public void removeSession(HttpSession session)(Code) Removes a session from the current list. This method should only be called by the listener. Parameters:   session - Session to remove shutdown public void shutdown()(Code) Returns to uninitialized state. Methods inherited from org.apache.turbine.services.TurbineBaseService public void init(Object data) throws InitializationException(Code)(Java Doc) public void init(ServletConfig config) throws InitializationException(Code)(Java Doc) public void init(RunData data) throws InitializationException(Code)(Java Doc) public void init() throws InitializationException(Code)(Java Doc) public void shutdown()(Code)(Java Doc)
