Method Detail

canHandle

public Authorization canHandle(Packet packet,
                               XMPPResourceConnection conn)

Description copied from interface: XMPPImplIfc

By default the method uses XMPPImplIfc.supElementNamePaths() and XMPPImplIfc.supTypes() method results to determine whether the plugin would process given packet. However, a plugin can implement own logic to determine packet processing capabilities or conditions. Please note, this method must be very fast and efficient. No I/O processing is recommended as it may impact performance of the whole system.

Specified by:

canHandle in interface XMPPImplIfc

Overrides:

canHandle in class XMPPProcessor

Parameters:

packet - is a Packet for processing.

conn - is a user session object or null.

Returns:

returns Authorization enum value or null. Null means the plugin is simply not processing the packet. Authorization.AUTHORIZED means the plugin can process the packet, any other Authorization enum value means an error which has to be returned to the sender.

init

public void init(Map<String,Object> settings)
          throws TigaseDBException

Description copied from interface: XMPPImplIfc

Method init is called just after the plugin has been loaded into memory. The idea behind this is to allow it to initialize or check the database. This might be especially useful for plugins which want to have a database access via non-standard stored procedures or need schema upgrade.

Specified by:

init in interface XMPPImplIfc

Overrides:

init in class XMPPProcessor

Parameters:

settings - is a Map with initial processor settings from the configuration file.

Throws:

TigaseDBException

id

public String id()

Description copied from interface: XMPPImplIfc

Method id returns a unique ID of the plugin. Each plugin has own, unique ID which is used in the configuration file to determine whether it needs to be loaded or not. In most cases the ID can be equal to XMLNS of the packages processed by the plugin.

Specified by:

id in interface XMPPImplIfc

Overrides:

id in class AnnotatedXMPPProcessor

Returns:

a String value

processFromUserToServerPacket

public void processFromUserToServerPacket(JID connectionId,
                                          Packet packet,
                                          XMPPResourceConnection session,
                                          NonAuthUserRepository repo,
                                          Queue<Packet> results,
                                          Map<String,Object> settings)
                                   throws PacketErrorTypeException

Description copied from class: XMPPProcessorAbstract

The method is called when a packet is send from the user who is owner of the session to the local server (ping, roster management, privacy lists, etc...). There is no default implementation for the method.

Specified by:

processFromUserToServerPacket in class XMPPProcessorAbstract

Parameters:

connectionId - is a JID instance with the session connection ID.

packet - is a Packet sent by the user.

session - is a XMPPResourceConnection instance with all the sending user session data.

repo - is a NonAuthUserRepository instance giving access to a part of the user repository which is accessible regardless the session is authenticated or not.

results - is a packets Queue with all the processing results from the plugin.

settings - is a Map with all the configuration settings passed to the plugin.

Throws:

PacketErrorTypeException - on attempt to send an error response to the error packet.

restorePacketForOffLineUser

public Queue<Packet> restorePacketForOffLineUser(List<String> db_ids,
                                                 XMPPResourceConnection conn,
                                                 MsgRepository repo)
                                          throws UserNotFoundException,
                                                 NotAuthorizedException

Throws:

UserNotFoundException

NotAuthorizedException

processServerSessionPacket

public void processServerSessionPacket(Packet packet,
                                       XMPPResourceConnection session,
                                       NonAuthUserRepository repo,
                                       Queue<Packet> results,
                                       Map<String,Object> settings)
                                throws PacketErrorTypeException

Description copied from class: XMPPProcessorAbstract

The method is called when a packet addressed to the server domain is received. Please note, if a local user sends a packet to the server, the packet is handled by the processFromUserPacket(...) method. This method is not called for such packets.

Specified by:

processServerSessionPacket in class XMPPProcessorAbstract

Parameters:

packet - is a Packet received by the server and addressed to the server - the server virtual domain name.

session - is a XMPPResourceConnection instance with all the server session data.

repo - is a NonAuthUserRepository instance giving access to a part of the user repository which is accessible regardless the session is authenticated or not.

results - is a packets Queue with all the processing results from the plugin.

settings - is a Map with all the configuration settings passed to the plugin.

Throws:

PacketErrorTypeException - on attempt to send an error response to the error packet.

supDiscoFeatures

public Element[] supDiscoFeatures(XMPPResourceConnection session)

Description copied from interface: XMPPImplIfc

Specified by:

supDiscoFeatures in interface XMPPImplIfc

Overrides:

supDiscoFeatures in class AnnotatedXMPPProcessor

Parameters:

session - a XMPPResourceConnection value

Returns:

an Element[] value

supElementNamePaths

Specified by:

supElementNamePaths in interface XMPPImplIfc

Overrides:

supElementNamePaths in class AnnotatedXMPPProcessor

Returns:

a String[][] value is an array for element paths for which the plugin offers processing capabilities. Each path is in form of a String array in order to reduce parsing overhead.

Method supNamespaces returns an array of name-spaces for stanzas which can be processed by this plugin. Each namespace corresponds to element name returned in array by supElemenets() method.

Specified by:

supNamespaces in interface XMPPImplIfc

Overrides:

supNamespaces in class AnnotatedXMPPProcessor

Returns:

a String[] value
