Interface WebAppSessionManager

    public interface WebAppSessionManager
extends WebSessionManager
    This is the interface for the MicroStrategy Web session manager. This interface contains methods for all session management related functionality. It maintains a WebIServerSessionList of WebIServerSession objects. It has an active session, which is the session that all requests will be directed to.

    Note that the standard calls that should be called on every page are restoreStateFromRequest and initActiveSessionFromRequest. These will ensure that the active session is set up to reflect any information passed in the state or saved in session variables or cookies. If a live session is expected, the validateSession method should be called after the above methods to ensure that the active session is live.

    • Method Detail

      • changeLocale

        void changeLocale()
        Changes the locale on all sessions in a cluster with the active one to the setting which is set on the session's preferences. This method will look at those preferences, and if they do not match the locale on the session, change the session locale, if we have enough information to recreate the session.

      • changeSessionFlags

        void changeSessionFlags()
        Changes the session flags for the session. This method will check the user session's prefrerences for the session and all sessions in the same cluster of servers, and if the current session flags are not the same as the session flags in the preferences, the session flags will be changed, if there exists enough information to recreate the session.

      • changePassword

        void changePassword​(java.lang.String oldP,
                    java.lang.String newP)
             throws WebAppException
        Changes the active session's password from the old password given to the new password.
        Parameters:
        oldP - The old password. Needed to confirm the correct user's identity.
        newP - The new password.
        Throws:
        WebAppException - Thrown if an error occurs when attempting to change password.

      • getSession

        WebIServerSession getSession​(java.lang.String server,
                             int port,
                             java.lang.String project)
        Returns the WebIServerSession for the given server/project. Will return null if the server is not connected (or cannot be auto-connected). It will also be made the current session.
        Returns:
        The current active session.
        Since:
        MicroStrategy Web 9.0.0

      • isAdminUser

        boolean isAdminUser()
        Returns whether the active session's user is an administrative user or not. This is checked via checking privileges.
        Returns:
        True if the active session's user has administrative privileges, false otherwise.

      • getProjectsList

        java.util.ArrayList getProjectsList​(boolean refresh)
                             throws WebAppException
        Returns an ArrayList of ProjectInformation objects, which contain information about the projects we are connected to.
        Parameters:
        refresh - A boolean variable indicates whether we should refresh the project list. If this parameter is false, and there is cached result of this call, we will return the last result, or throw the same exception as last time. If this parameter is true, we will ingore the cache and refresh the project list.
        Returns:
        An ArrayList of ProjectInformation objects.
        Throws:
        WebAppException - Thrown if an error occurs.

      • removeAllSessions

        void removeAllSessions()
        Removes all sessions from the list, closing them if the external security manager setup on the application context says to do so.

      • removeActiveSession

        void removeActiveSession()
        Removes the active session from the list, closing it if the external security manager setup on the application context says to do so.

      • validateSession

        void validateSession()
              throws WebAppException
        This method attempts to validate the active session. If the session cannot be validated, then it can also attempt to recover for a specific set of error conditions. If the session cannot be validated or recovered, this method will throw an exception. If an exception is not thrown, then the session is valid. If there is result of previous validateSession call, it will not re-do the validation, install just returns the same validation result. If you need do the validation regardless the previous result, use validateSession(boolean) passing true as parameter.
        Throws:
        WebAppException - Thrown if the active session is confirmed to be invalid.

      • validateSession

        void validateSession​(boolean refresh)
              throws WebAppException
        This method attempts to validate the active session. If the session cannot be validated, then it can also attempt to recover for a specific set of error conditions. If the session cannot be validated or recovered, this method will throw an exception. If an exception is not thrown, then the session is valid.
        Parameters:
        refresh - The boolean vairable indicates whether we should use previous validation result. If this is false and there is result of previous validateSession call, it will not re-do the validation, install just returns the same validation result. Eitherwise, it will do the validation process.
        Throws:
        WebAppException - Thrown if the active session is confirmed to be invalid.
