    • doStart

      protected void doStart() throws Exception
      Description copied from class: ContainerLifeCycle

      Overrides:
      doStart in class AbstractSessionDataStore
      Throws:
      AbstractLifeCycle.StopException - If thrown, the lifecycle will immediately be stopped.
      Exception - If there was a problem starting. Will cause a transition to FAILED state

    • doStop

      protected void doStop() throws Exception
      Description copied from class: ContainerLifeCycle
      Stops the managed lifecycle beans in the reverse order they were added.
      Overrides:
      doStop in class ContainerLifeCycle
      Throws:
      Exception - If there was a problem stopping. Will cause a transition to FAILED state

    • initialize

      public void initialize() throws Exception
      Throws:
      Exception

    • doLoad

      public SessionData doLoad(String id) throws Exception
      Description copied from class: AbstractSessionDataStore
      Load the session from persistent store.
      Specified by:
      doLoad in class AbstractSessionDataStore
      Parameters:
      id - the id of the session to load
      Returns:
      the re-inflated session
      Throws:
      Exception - if unable to load the session

    • delete

      public boolean delete(String id) throws Exception
      Description copied from interface: SessionDataMap
      Delete session data
      Parameters:
      id - identity of session to delete
      Returns:
      true if the session was deleted
      Throws:
      Exception - if unable to delete session data

    • doStore

      public void doStore(String id, SessionData data, long lastSaveTime) throws Exception
      Description copied from class: AbstractSessionDataStore
      Store the session data persistently.
      Specified by:
      doStore in class AbstractSessionDataStore
      Parameters:
      id - identity of session to store
      data - info of the session
      lastSaveTime - time of previous save or 0 if never saved
      Throws:
      Exception - if unable to store data

    • doInsert

      protected void doInsert(String id, SessionData data) throws Exception
      Throws:
      Exception

    • doUpdate

      protected void doUpdate(String id, SessionData data) throws Exception
      Throws:
      Exception

    • doCheckExpired

      public Set<String> doCheckExpired(Set<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 Set<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)

    • setSessionTableSchema

      public void setSessionTableSchema(JDBCSessionDataStore.SessionTableSchema schema)

    • 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(String id) throws 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:
      Exception
