Method Detail

getAllPrincipals

Object[] getAllPrincipals()

Obtains all the known principals in the SessionRegistry.

each of the unique principals, which can then be presented to getAllSessions(Object, boolean).

getAllSessions

SessionInformation[] getAllSessions(Object principal,
                                    boolean includeExpiredSessions)

Obtains all the known sessions for the specified principal. Sessions that have been destroyed are not returned. Sessions that have expired may be returned, depending on the passed argument.

Parameters:

principal - to locate sessions for (should never be null)

includeExpiredSessions - if true, the returned sessions will also include those that have expired for the principal

Returns:

the matching sessions for this principal, or null if none were found

getSessionInformation

SessionInformation getSessionInformation(String sessionId)

Obtains the session information for the specified sessionId. Even expired sessions are returned (although destroyed sessions are never returned).

Parameters:

sessionId - to lookup (should never be null)

Returns:

the session information, or null if not found

refreshLastRequest

void refreshLastRequest(String sessionId)

Updates the given sessionId so its last request time is equal to the present date and time. Silently returns if the given sessionId cannot be found or the session is marked to expire.

Parameters:

sessionId - for which to update the date and time of the last request (should never be null)

registerNewSession

void registerNewSession(String sessionId,
                        Object principal)
