      • doCheckExpired

        public java.util.Set<java.lang.String> doCheckExpired​(java.util.Set<java.lang.String> candidates,
                                                              long time)
        Description copied from class: AbstractSessionDataStore
        Implemented by subclasses to resolve which sessions in this context that are being managed by this node that should be expired.
        Specified by:
        doCheckExpired in class AbstractSessionDataStore
        Parameters:
        candidates - the ids of sessions the SessionCache thinks has expired
        time - the time at which to check for expiry
        Returns:
        the reconciled set of session ids that have been checked in the store
      • doGetExpired

        public java.util.Set<java.lang.String> doGetExpired​(long timeLimit)
        Description copied from class: AbstractSessionDataStore
        Implemented by subclasses to find sessions for this context in the store that expired at or before the time limit and thus not being actively managed by any node. This method is only called periodically (the period is configurable) to avoid putting too much load on the store.
        Specified by:
        doGetExpired in class AbstractSessionDataStore
        Parameters:
        timeLimit - the upper limit of expiry times to check. Sessions expired at or before this timestamp will match.
        Returns:
        the empty set if there are no sessions expired as at the time, or otherwise a set of session ids.
      • doCleanOrphans

        public void doCleanOrphans​(long time)
        Description copied from class: AbstractSessionDataStore
        Implemented by subclasses to delete sessions for other contexts that expired at or before the timeLimit. These are 'orphaned' sessions that are no longer being actively managed by any node. These are explicitly sessions that do NOT belong to this context (other mechanisms such as doGetExpired take care of those). As they don't belong to this context, they cannot be loaded by us. This is called only periodically to avoid placing excessive load on the store.
        Specified by:
        doCleanOrphans in class AbstractSessionDataStore
        Parameters:
        time - the upper limit of the expiry time to check in msec
      • setDatabaseAdaptor

        public void setDatabaseAdaptor​(DatabaseAdaptor dbAdaptor)
      • isPassivating

        @ManagedAttribute(value="does this store serialize sessions",
                          readonly=true)
        public boolean isPassivating()
        Description copied from interface: SessionDataStore
        True if this type of datastore will passivate session objects
        Returns:
        true if this store can passivate sessions, false otherwise
      • doExists

        public boolean doExists​(java.lang.String id)
                         throws java.lang.Exception
        Description copied from class: AbstractSessionDataStore
        Check if a session for the given id exists.
        Specified by:
        doExists in class AbstractSessionDataStore
        Parameters:
        id - the session id to check
        Returns:
        true if the session exists in the persistent store, false otherwise
        Throws:
        java.lang.Exception
