Class IQPrivateHandler

  • All Implemented Interfaces:
    ChannelHandler, Module, ServerFeaturesProvider

    public class IQPrivateHandler
    extends IQHandler
    implements ServerFeaturesProvider
    Implements the TYPE_IQ jabber:iq:private protocol. Clients use this protocol to store and retrieve arbitrary application configuration information. Using the server for setting storage allows client configurations to follow users where ever they go.

    A 'get' query retrieves any stored data. A 'set' query stores new data.

    Currently an empty implementation to allow usage with normal clients. Future implementation needed.


    This handler assumes that the request is addressed to the server. An appropriate TYPE_IQ tag matcher should be placed in front of this one to route TYPE_IQ requests not addressed to the server to another channel (probably for direct delivery to the recipient).


    There should be a way of determining whether a session has authorization to access this feature. I'm not sure it is a good idea to do authorization in each handler. It would be nice if the framework could assert authorization policies across channels.

      • initialize

        public void initialize​(XMPPServer server)
        Description copied from class: BasicModule

        Initializes the basic module.

        Inheriting classes that choose to override this method MUST call this initialize() method before accessing BasicModule resources.

        Specified by:
        initialize in interface Module
        initialize in class IQHandler
        server - the server hosting this module.
      • getInfo

        public IQHandlerInfo getInfo()
        Description copied from class: IQHandler
        Returns the handler information to help generically handle IQ packets. IQHandlers that aren't local server iq handlers (e.g. chatbots, transports, etc) return null.
        Specified by:
        getInfo in class IQHandler
        The IQHandlerInfo for this handler
      • getFeatures

        public Iterator<String> getFeatures()
        Description copied from interface: ServerFeaturesProvider
        Returns an Iterator (of String) with the supported features by the server. The features to include are the features offered and supported protocols by the SERVER. The idea is that different modules may provide their features that will ultimately be part of the features offered by the server.
        Specified by:
        getFeatures in interface ServerFeaturesProvider
        an Iterator (of String) with the supported features by the server.
