      • 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.

      • id

        public java.lang.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,

                                   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.

      • processServerSessionPacket

        public void processServerSessionPacket​(Packet packet,
                                       XMPPResourceConnection session,
                                       NonAuthUserRepository repo,
                                       java.util.Queue<Packet> results,

        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.
