Method Detail

componentAdded

public void componentAdded(StatisticsContainer component)

Description copied from class: AbstractComponentRegistrator

Method provides a callback mechanism signaling that a new component implementing special interface has been added to the internal components collection.

Specified by:

componentAdded in class AbstractComponentRegistrator<StatisticsContainer>

Parameters:

component - is a reference to the component just added to the collection.

componentRemoved

public void componentRemoved(StatisticsContainer component)

Description copied from class: AbstractComponentRegistrator

Method provides a callback mechanism signaling that a component implementing special interface has been removed from the internal components collection.

Specified by:

componentRemoved in class AbstractComponentRegistrator<StatisticsContainer>

Parameters:

component - is a reference to the component removed from the collection.

initializationCompleted

public void initializationCompleted()

Description copied from interface: ServerComponent

Method is called by MessageRouter when all the startup components of the server have been loaded and configured through setProperties(...) call. At this point the whole server should be loaded and functional, except initializations taking place in this routine.

Specified by:

initializationCompleted in interface ServerComponent

Overrides:

initializationCompleted in class BasicComponent

processPacket

public void processPacket(Packet packet,
                          Queue<Packet> results)

Description copied from interface: ServerComponent

processPacket is a blocking processing method implemented by all components. This method processes packet and returns results instantly without waiting for any resources.

Specified by:

processPacket in interface ServerComponent

Overrides:

processPacket in class BasicComponent

Parameters:

packet - a Packet value

release

public void release()

Description copied from interface: ServerComponent

Method description

Specified by:

release in interface ServerComponent

Overrides:

release in class AbstractComponentRegistrator<StatisticsContainer>

shutdown

public String shutdown()

Specified by:

shutdown in interface ShutdownHook

getAllStats

public StatisticsList getAllStats()

getAllStats

public void getAllStats(StatisticsList list)

getComponentsNames

public List<String> getComponentsNames()

getComponentStats

public void getComponentStats(String name,
                              StatisticsList list)

getDefaults

public Map<String,Object> getDefaults(Map<String,Object> params)

Description copied from interface: Configurable

Returns default configuration settings for the component as a Map with keys as configuration property IDs and values as the configuration property values. All the default parameters returned from this method are later passed to the setProperties(...) method. Some of them may have changed value if they have been overwritten in the server configuration. The configuration property value can be of any of the basic types: int, long, boolean, String.

Specified by:

getDefaults in interface Configurable

Overrides:

getDefaults in class BasicComponent

Parameters:

params - is a Map with some initial properties set for the starting up server. These parameters can be used as a hints to generate component's default configuration.

Returns:

a Map with the component default configuration.

getDiscoFeatures

public List<Element> getDiscoFeatures(JID from)

Description copied from interface: XMPPService

Returns features for top level disco info

Specified by:

getDiscoFeatures in interface XMPPService

Overrides:

getDiscoFeatures in class BasicComponent

Parameters:

from - a request sender address. Some service disco elements are meant to be available only to system administrarors. The component is responsible to check whether the sender is the component administrator and return results appropriate.

Returns:

a list of elements with service discovery features.

getDiscoInfo

public Element getDiscoInfo(String node,
                            JID jid,
                            JID from)

Description copied from interface: XMPPService

Returns service discovery info for the component. If the jid is null then this is info for the top level request. SM may return disco info on the top level. Other components should not.

Specified by:

getDiscoInfo in interface XMPPService

Overrides:

getDiscoInfo in class BasicComponent

Parameters:

node - is service discovery node for which the request is made. Is normally null for the component top level request.

jid - is the jid to which the request has been made.

from - is the request sender address. Some service discovery information is only meant for administrators.

Returns:

returns an XML Element with service discovery data.

getDiscoItems

public List<Element> getDiscoItems(String node,
                                   JID jid,
                                   JID from)

Description copied from interface: XMPPService

Returns service discovery items for the component. If the JID is null then this is request for the top level request. SM may return disco items on the top level, other components should just return it's top level service discovery item for null node.

Specified by:

getDiscoItems in interface XMPPService

Overrides:

getDiscoItems in class BasicComponent

Parameters:

node - is a service discovery node for which the request has been made.

jid - is the jid to which the request has been made.

from - is the request sender address. Some service discovery information is only meant for administrators.

Returns:

a list of service discovery items for this component or the component itself disco item for the top level request.

getName in interface ShutdownHook

Overrides:

getName in class BasicComponent

isCorrectType

public boolean isCorrectType(ServerComponent component)

Description copied from class: AbstractComponentRegistrator

Method checks whether the component provides as method parameter is correct type that is implements special interface or extends special class. Result of the method determines whether the component can be added to the internal components collection.

Specified by:

isCorrectType in class AbstractComponentRegistrator<StatisticsContainer>
