          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:

    - #### processFromUserPacket

          public void processFromUserPacket​(JID connectionId,
                                            Packet packet,
                                            XMPPResourceConnection session,
                                            NonAuthUserRepository repo,
                                            java.util.Queue<Packet> results,
                                            java.util.Map<java.lang.String,​java.lang.Object> settings)
                                     throws PacketErrorTypeException

      Description copied from class: `XMPPProcessorAbstract`
      The method is called for all packets sent by the user, owner of this connection/session. Please note, it is likely that a user sends a packet addressed to his own server, like get server version information. In such a case only this method is called. Such a packet is not later passed to the `processServerSessionPacket(...)`. Note, the default implementation checks whether the packet is addressed to the server or is being sent to another XMPP entity. In the first case it calls `processFromUserToServerPacket(...)` method, otherwise it calls `processFromUserOutPacket`. You can overwrite the method to change the default behavior or implement the two called methods to handle each case separately.
      Overrides:
        `processFromUserPacket` 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.

    - #### processFromUserOutPacket

          public void processFromUserOutPacket​(JID connectionId,
                                               Packet packet,
                                               XMPPResourceConnection session,
                                               NonAuthUserRepository repo,
                                               java.util.Queue<Packet> results,
                                               java.util.Map<java.lang.String,​java.lang.Object> settings)

      Description copied from class: `XMPPProcessorAbstract`
      The method is called when a packet is sent from the user, owner of the session somewhere else to other XMPP entity (other user on the server, other user on a different server, different server, component, transport, etc....). The default implementation just forwards the packet doing nothing else, which is good enough in most cases. You can overwrite the method to change the default behaviour.
      Overrides:
        `processFromUserOutPacket` 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.

    - #### processFromUserToServerPacket

                                                    XMPPResourceConnection session,
                                                    NonAuthUserRepository repo,
                                                    java.util.Queue<Packet> results,
                                                    java.util.Map<java.lang.String,​java.lang.Object> settings)

      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.

    - #### processServerSessionPacket

          public void processServerSessionPacket​(Packet packet,

      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.
