Method Detail

containsJid

public boolean containsJid(BareJID jid)

Description copied from interface: OnlineJidsReporter

The method checks whether the given JID is known to the installation, either user connected to local machine or any of the cluster nodes. False result does not mean the user is not connected. It means the method does not know anything about the JID. Some clustering strategies may not cache online users information.

Specified by:

containsJid in interface OnlineJidsReporter

Overrides:

containsJid in class SessionManager

Parameters:

jid - a user's JID for whom we query information.

Returns:

true if the user is known as online to the installation, false if the method does not know.

everySecond

public void everySecond()

Description copied from class: AbstractMessageReceiver

Utility method executed precisely every second. A component can overwrite the method to put own code to be executed at the regular intervals of time.
Note, no extensive calculations should happen in this method nor long lasting operations. It is essential that the method processing does not exceed 1 second. The overriding method must call the the super method first and only then run own code.

Overrides:

everySecond in class SessionManager

everyMinute

public void everyMinute()

Description copied from class: AbstractMessageReceiver

Utility method executed precisely every minute. A component can overwrite the method to put own code to be executed at the regular intervals of time.
Note, no extensive calculations should happen in this method nor long lasting operations. It is essential that the method processing does not exceed 1 minute. The overriding method must call the the super method first and only then run own code.

Overrides:

everyMinute in class SessionManager

everyHour

public void everyHour()

Description copied from class: AbstractMessageReceiver

Utility method executed precisely every hour. A component can overwrite the method to put own code to be executed at the regular intervals of time.
Note, no extensive calculations should happen in this method nor long lasting operations. It is essential that the method processing does not exceed 1 hour. The overriding method must call the the super method first and only then run own code.

Overrides:

everyHour in class AbstractMessageReceiver

fastAddOutPacket

public boolean fastAddOutPacket(Packet packet)

Specified by:

fastAddOutPacket in interface SessionManagerClusteredIfc

Overrides:

                              XMPPResourceConnection conn)

Overrides:

public void handleLogin(BareJID userId,
                        XMPPResourceConnection conn)

Parameters:

binds - A mapping of key/value pairs, all of whose keys are Strings.

onNodeConnected

public void onNodeConnected(JID jid)

Overrides:

onNodeConnected in class BasicComponent

onNodeDisconnected

public void onNodeDisconnected(JID jid)

Overrides:

processingInThreads

public int processingInThreads()

Description copied from class: AbstractMessageReceiver

Concurrency control method. Returns preferable number of threads set for this component.

Overrides:

processingInThreads in class SessionManager

Returns:

preferable number of threads set for this component.

processingOutThreads

public int processingOutThreads()

Description copied from class: AbstractMessageReceiver

Concurrency control method. Returns preferable number of threads set for this component.

Overrides:

processingOutThreads in class SessionManager

Returns:

preferable number of threads set for this component.

processPacket

public void processPacket(Packet packet)

This is the main Packet processing method. It is called concurrently from many threads so implementing it in thread save manner is essential. The method is called for each packet addressed to the component.
Please note, the Packet instance may be processed by different parts of the server, different components or plugins at the same time. Therefore this is very important to tread the Packet instance as unmodifiable object.
Processing in this method is asynchronous, therefore there is no result value. If there are some 'result' packets generated during processing, they should be passed back using addOutPacket(Packet) method.


This is a standard component method for processing packets. The method takes care of cases where the packet cannot be processed locally, in such a case it is forwarded to another node.

Overrides:

processPacket in class SessionManager

Parameters:

packet - to be processed

processPacket

public void processPacket(Packet packet,
                          XMPPResourceConnection conn)

Specified by:

processPacket in interface SessionManagerClusteredIfc

Overrides:

processPacket in class SessionManager

processPresenceUpdate

public void processPresenceUpdate(XMPPSession session,
                                  Element packet)

Specified by:

processPresenceUpdate in interface SessionManagerClusteredIfc

Overrides:

processPresenceUpdate in class SessionManager

getComponentInfo

public ComponentInfo getComponentInfo()

Description copied from interface: ServerComponent

Allows to obtain various informations about components

Specified by:

getComponentInfo in interface ServerComponent

Overrides:

getComponentInfo in class BasicComponent

Returns:

information about particular component

getConnectionIdsForJid

public JID[] getConnectionIdsForJid(BareJID jid)

Retrieve all connection IDs (CIDs) for the given user.
If the installation knows about user's JID, that he is connected to the system, then this method returns all user's connection IDs. As an optimization we can forward packets to all user's connections directly from a single node.

Specified by:

getConnectionIdsForJid in interface OnlineJidsReporter

Overrides:

getConnectionIdsForJid in class SessionManager

Parameters:

jid - a user's JID for whom we query information.

Returns:

a list of all user's connection IDs.

getDiscoDescription

public String getDiscoDescription()

Description copied from class: BasicComponent

Method returns description used for service discovery responses.

Overrides:

getDiscoDescription in class SessionManager

Returns:

description of a component

getStatistics

public void getStatistics(StatisticsList list)

Description copied from class: AbstractMessageReceiver

Method returns component statistics. Please note, the method can be called every second by the server monitoring system therefore no extensive or lengthy calculations are allowed. If there are some statistics requiring lengthy operations like database access they must have Level.FINEST assigned and must be put inside the level guard to prevent generating them by the system monitor. The system monitor does not collect FINEST statistics.
Level guard code looks like the example below:

 if (list.checkLevel(Level.FINEST)) {
   // Some CPU intensive calculations or lengthy operations
   list.add(getName(), "Statistic description", stat_value, Level.FINEST);
 }

 

This way you make sure your extensive operation is not executed every second by the monitoring system and does not affect the server performance.

Specified by:

getStatistics in interface StatisticsContainerIfc

Overrides:

getStatistics in class SessionManager

Parameters:

list - is a StatistcsList where all statistics are stored.

getStrategy

public ClusteringStrategyIfc getStrategy()

Returns active clustering strategy object.

Returns:

active clustering strategy object.

Specified by:

getXMPPResourceConnections in interface SessionManagerClusteredIfc

getXMPPSessions

public ConcurrentHashMap<BareJID,XMPPSession> getXMPPSessions()

Specified by:

getXMPPSessions in interface SessionManagerClusteredIfc

hasCompleteJidsInfo

public boolean hasCompleteJidsInfo()

Description copied from interface: OnlineJidsReporter

Method checks whether the clustering strategy has a complete JIDs info. That is whether the strategy knows about all users connected to all nodes. Some strategies may choose not to share this information among nodes, hence the methods returns false. Other may synchronize this information and can provide it to further optimize cluster traffic.

Specified by:

hasCompleteJidsInfo in interface OnlineJidsReporter

Overrides:

hasCompleteJidsInfo in class SessionManager

Returns:

a true boolean value if the strategy has a complete information about all users connected to all cluster nodes.
