    • 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
      canHandle in class XMPPProcessor
      packet - is a Packet for processing.
      conn - is a user session object or null.
      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 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
      a String value
    • process

      public void process(Packet packet, XMPPResourceConnection session, NonAuthUserRepository repo, Queue<Packet> results, Map<String,Object> settings) throws XMPPException
      Specified by:
      process in interface XMPPProcessorIfc
      packet - packet is which being processed. This parameter may never be null. Even though this is not immutable object it mustn't be altered. None of it's fields or attributes can be changed during processing.
      session - user session which keeps all the user session data and also gives an access to the user's repository data. It allows for storing information in a permanent storage or in memory only during the live of the online session. This parameter can be null if there is no online user session at the time of the packet processing.
      repo - this is a user data storage which is normally used when the user session (parameter above) is null. This is repository allows for a very restricted access only. It allows for storing some user private data (doesn't allow overwriting existing data) like messages for offline users and it also allows for reading user public data like VCard.
      results - this a collection with packets which have been generated as input packet processing results. Regardless a response to a user request is sent or the packet is forwarded to it's destination it is always required that a copy of the input packet is created and stored in the results queue.
      settings - this map keeps plugin specific settings loaded from the Tigase server configuration. In most cases it is unused, however if the plugin needs to access an external database that this is a way to pass database connection string to the plugin.
    • 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
      supDiscoFeatures in class XMPPProcessor
      session - a XMPPResourceConnection value
      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
      supElementNamePaths in class XMPPProcessor
      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.
    • supNamespaces

      public String[] supNamespaces()
      Description copied from interface: XMPPImplIfc
      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
      supNamespaces in class XMPPProcessor
      a String[] value
