public DefaultSessionCache(AbstractSessionManager sessionManager,
 SessionStore sessionStore,
 boolean clusterEnabled)

Method Details

getMaxActiveSessions

public int getMaxActiveSessions()

setMaxActiveSessions

public void setMaxActiveSessions(int maxActiveSessions)

Description copied from interface: SessionCache

Sets the maximum number of active sessions allowed in this session cache. The number of active sessions exceeds this limit, attempts to create new sessions will be rejected. If set to 0 (the default), there is no limit.

Parameters:

maxActiveSessions - the maximum number of active sessions allowed in this session cache

doGet

protected ManagedSession doGet(String id)

Description copied from class: AbstractSessionCache

Get the session matching the key.

Specified by:

doGet in class AbstractSessionCache

Parameters:

id - the session id

Returns:

the Session object matching the id

doPutIfAbsent

protected ManagedSession doPutIfAbsent(String id,
 ManagedSession session)

Description copied from class: AbstractSessionCache

Put the session into the map if it wasn't already there.

Specified by:

doPutIfAbsent in class AbstractSessionCache

Parameters:

id - the identity of the session

session - the session object

Returns:

null if the session wasn't already in the map, or the existing entry otherwise

doComputeIfAbsent

protected ManagedSession doComputeIfAbsent(String id,
 Function<String,ManagedSession> mappingFunction)

Description copied from class: AbstractSessionCache

Compute the mappingFunction to create a Session object if the session with the given id isn't already in the map, otherwise return the existing Session. This method is expected to have precisely the same behaviour as ConcurrentHashMap.computeIfAbsent(K, java.util.function.Function<? super K, ? extends V>)

Specified by:

doComputeIfAbsent in class AbstractSessionCache

Parameters:

id - the session id

mappingFunction - the function to load the data for the session

Returns:

an existing Session from the cache

doDelete

protected ManagedSession doDelete(String id)

Description copied from class: AbstractSessionCache

Remove the session with this identity from the store.

Specified by:

doDelete in class AbstractSessionCache

Parameters:

id - the session id

Returns:

the Session object if removed; null otherwise

getActiveSessions

public Set<String> getActiveSessions()

Returns:

the identifiers of those sessions that are active on this node, excluding passivated sessions

getAllSessions

public Set<String> getAllSessions()

Returns:

the identifiers of all sessions, including both active and passive

doInitialize

protected void doInitialize()
                     throws Exception

Specified by:

doInitialize in class AbstractComponent

Throws:

Exception

doDestroy

protected void doDestroy()
                  throws Exception

Specified by:

doDestroy in class AbstractComponent

Throws:

Exception

toString

public String toString()

Overrides:

toString in class Object
