      • 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
        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

        @Deprecated
public void init​(Map<String,​Object> settings)
          throws TigaseDBException
        Deprecated.
        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
        Parameters:
        settings - is a Map with initial processor settings from the configuration file.
        Throws:
        TigaseDBException

      • supDiscoFeatures

        public Element[] supDiscoFeatures​(XMPPResourceConnection session)
        Description copied from interface: XMPPImplIfc
        Method supDiscoFeatures returns an array of XML Elements with service discovery features which have to be returned to the client uppon request. Service discovery features returned by this method correspond to services supported by this plugin.
        Specified by:
        supDiscoFeatures in interface XMPPImplIfc
        Parameters:
        session - a XMPPResourceConnection value
        Returns:
        an Element[] value

      • supElementNamePaths

        public String[][] supElementNamePaths()
        Description copied from interface: XMPPImplIfc
        Method supElementNamePaths returns an array of element names in form of a full path to the XML element for stanzas which can be processed by this plugin. Each element name path corresponds to XMLNS returned in array by supNamespaces() method. The element path itself is represented by a String array with each path element as a separate String.
        Specified by:
        supElementNamePaths in interface XMPPImplIfc
        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.

      • supElements

public String[] supElements()
        Deprecated.
        Description copied from interface: XMPPImplIfc
        Method supElements returns an array of element names for stanzas which can be processed by this plugin. Each element name corresponds to XMLNS returned in array by supNamespaces() method. This method has been deprecated in favor of supElementNamePaths.
        Specified by:
        supElements in interface XMPPImplIfc
        Returns:
