Constructor Detail

DefaultSessionCache

public DefaultSessionCache(SessionHandler sessionHandler,
                           SessionStore sessionStore,
                           boolean clusterEnabled)

Method Detail

getMaxSessions

public int getMaxSessions()

setMaxSessions

public void setMaxSessions(int maxSessions)

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:

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

doGet

protected DefaultSession doGet(java.lang.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 DefaultSession doPutIfAbsent(java.lang.String id,
                                       DefaultSession 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 DefaultSession doComputeIfAbsent(java.lang.String id,
                                           java.util.function.Function<java.lang.String,DefaultSession> 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 DefaultSession doDelete(java.lang.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:

true if removed; false otherwise

doReplace

protected boolean doReplace(java.lang.String id,
                            DefaultSession oldValue,
                            DefaultSession newValue)

Description copied from class: AbstractSessionCache

Replace the mapping from id to oldValue with newValue.

Specified by:

doReplace in class AbstractSessionCache

Parameters:

id - the session id

oldValue - the old value

newValue - the new value

Returns:

true if replacement was done

getAllSessions

public java.util.Set<java.lang.String> getAllSessions()

getActiveSessionCount

public long getActiveSessionCount()

Returns:

the number of sessions in the cache

getHighestSessionCount

public long getHighestSessionCount()

Returns:

the max number of sessions in the cache

getCreatedSessionCount

public long getCreatedSessionCount()

Returns:

a running total of sessions in the cache

getExpiredSessionCount

public long getExpiredSessionCount()

getRejectedSessionCount

public long getRejectedSessionCount()

resetStatistics

public void resetStatistics()

Description copied from interface: SessionCache

Resets the running total session count in the cache.

doInitialize

protected void doInitialize()
                     throws java.lang.Exception

Specified by:

doInitialize in class AbstractComponent

Throws:

java.lang.Exception

doDestroy
