  - ### Method Detail

    - #### getDiscoInfo

          Element getDiscoInfo(String node,
                               JID jid,
                               JID from)

      Returns service discovery info for the component. If the jid is null then this is info for the top level request. SM may return disco info on the top level. Other components should not.
      Parameters:
        `node` - is service discovery node for which the request is made. Is normally null for the component top level request.
        `jid` - is the jid to which the request has been made.
        `from` - is the request sender address. Some service discovery information is only meant for administrators.
      Returns:
        returns an XML Element with service discovery data.

    - #### getDiscoItems

          List<Element> getDiscoItems(String node,
                                      JID jid,
                                      JID from)

      Returns service discovery items for the component. If the JID is null then this is request for the top level request. SM may return disco items on the top level, other components should just return it's top level service discovery item for null node.
      Parameters:
        `node` - is a service discovery node for which the request has been made.
        `jid` - is the jid to which the request has been made.
        `from` - is the request sender address. Some service discovery information is only meant for administrators.
      Returns:
        a list of service discovery items for this component or the component itself disco item for the top level request.

    - #### getDiscoFeatures

          List<Element> getDiscoFeatures(JID from)

      Returns features for top level disco info
      Parameters:
        `from` - a request sender address. Some service disco elements are meant to be available only to system administrarors. The component is responsible to check whether the sender is the component administrator and return results appropriate.
