public IQOfflineMessagesHandler()
Method Detail

handleIQ

public IQ handleIQ(IQ packet)
            throws UnauthorizedException
Description copied from class: IQHandler
Handles the received IQ packet.

Specified by:
handleIQ in class IQHandler
Parameters:
packet - the IQ packet to handle.
Returns:
the response to send back.
Throws:
UnauthorizedException - if the user that sent the packet is not authorized to request the given operation.

getInfo

public IQHandlerInfo getInfo()
Description copied from class: IQHandler
Returns the handler information to help generically handle IQ packets. IQHandlers that aren't local server iq handlers (e.g. chatbots, transports, etc) return null.

Specified by:
getInfo in class IQHandler
Returns:
The IQHandlerInfo for this handler

getFeatures

public Iterator<String> getFeatures()
Description copied from interface: ServerFeaturesProvider
Returns an Iterator (of String) with the supported features by the server. The features to include are the features offered and supported protocols by the SERVER. The idea is that different modules may provide their features that will ultimately be part of the features offered by the server.

Specified by:
getFeatures in interface ServerFeaturesProvider
Returns:
an Iterator (of String) with the supported features by the server.

getIdentities

public Iterator<org.dom4j.Element> getIdentities(String name,
                                                 String node,
                                                 JID senderJID)
Description copied from interface: DiscoInfoProvider
Returns an Iterator (of Element) with the target entity's identities. Each Element must include the categoty, type and name attributes of the entity.

Specified by:
getIdentities in interface DiscoInfoProvider
Parameters:
name - the recipient JID's name.
node - the requested disco node.
senderJID - the XMPPAddress of user that sent the disco info request.
Returns:
an Iterator (of Element) with the target entity's identities.

getFeatures

public Iterator<String> getFeatures(String name,
                                    String node,
                                    JID senderJID)
Description copied from interface: DiscoInfoProvider
Returns an Iterator (of String) with the supported features. The features to include are the features offered and supported protocols by the target entity identified by the requested name and node.

Specified by:
getFeatures in interface DiscoInfoProvider
Parameters:
name - the recipient JID's name.
node - the requested disco node.
senderJID - the XMPPAddress of user that sent the disco info request.
Returns:
an Iterator (of String) with the supported features.

getExtendedInfo

public XDataFormImpl getExtendedInfo(String name,
                                     String node,
                                     JID senderJID)
Description copied from interface: DiscoInfoProvider
Returns an XDataForm with the extended information about the entity or null if none. Each bit of information about the entity must be included as a value of a field of the form.

Specified by:
getExtendedInfo in interface DiscoInfoProvider
Parameters:
name - the recipient JID's name.
node - the requested disco node.
senderJID - the XMPPAddress of user that sent the disco info request.
Returns:
an XDataForm with the extended information about the entity or null if none.

hasInfo

public boolean hasInfo(String name,
                       String node,
                       JID senderJID)
Description copied from interface: DiscoInfoProvider
Returns true if we can provide information related to the requested name and node. For example, if the requested name refers to a non-existant MUC room then the answer will be false. In case that the sender of the disco request is not authorized to discover this information an UnauthorizedException will be thrown.

Specified by:
hasInfo in interface DiscoInfoProvider
Parameters:
name - the recipient JID's name.
node - the requested disco node.
senderJID - the XMPPAddress of user that sent the disco info request.
Returns:
true if we can provide information related to the requested name and node.

getItems

public Iterator<org.dom4j.Element> getItems(String name,
                                            String node,
                                            JID senderJID)
Description copied from interface: DiscoItemsProvider
Returns an Iterator (of Element) with the target entity's items or null if none. Each Element must include a JID attribute and may include the name and node attributes of the entity. In case that the sender of the disco request is not authorized to discover items an UnauthorizedException will be thrown.

Specified by:
getItems in interface DiscoItemsProvider
Parameters:
name - the recipient JID's name.
node - the requested disco node.
senderJID - the XMPPAddress of user that sent the disco items request.
Returns:
an Iterator (of Element) with the target entity's items or null if none.

initialize

public void initialize(XMPPServer server)
Description copied from class: BasicModule

Initializes the basic module.

Inheriting classes that choose to override this method MUST call this initialize() method before accessing BasicModule resources.

initialize in class IQHandler
Parameters:
server - the server hosting this module.

start

public void start()
           throws IllegalStateException
Description copied from class: BasicModule

Starts the basic module.

Inheriting classes that choose to override this method MUST call this start() method before accessing BasicModule resources.

IllegalStateException - If start is called before initialize successfully returns

stop

public void stop()
Description copied from class: BasicModule
