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

newSessionData

public SessionData newSessionData(String id,
                                  long created,
                                  long accessed,

Specified by:

newSessionData in interface SessionDataStore

Overrides:

newSessionData in class AbstractSessionDataStore

Parameters:

id - the id

created - the timestamp when created

accessed - the timestamp when accessed

lastAccessed - the timestamp when last accessed

maxInactiveMs - the max inactive time in milliseconds

Returns:

a new SessionData object

delete

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)

Parameters:

candidates - the ids of sessions the SessionDataStore thinks has expired

Returns:

the reconciled set of session ids that this node should attempt to expire

isPassivating

@ManagedAttribute(value="does this store serialize sessions",
                  readonly=true)
