dbus: Methods and Signal

 
 2.5 Applying the functionality.
 ===============================
 
 Methods and signals are the communication means to D-Bus.  The following
 functions return their specifications.
 
  -- Function: dbus-introspect-get-method-names bus service path
           interface
      Return a list of strings of all method names of INTERFACE of
      SERVICE in D-Bus BUS at object path PATH.  Example:
 
           (dbus-introspect-get-method-names
             :session "org.freedesktop.xesam.searcher"
             "/org/freedesktop/xesam/searcher/main"
             "org.freedesktop.xesam.Search")
 
           ⇒ ("GetState" "StartSearch" "GetHitCount" "GetHits" "NewSession"
               "CloseSession" "GetHitData" "SetProperty" "NewSearch"
               "GetProperty" "CloseSearch")
 
  -- Function: dbus-introspect-get-method bus service path interface
           method
      This function returns METHOD of INTERFACE as XML element.  It must
      be located at SERVICE in D-Bus BUS at object path PATH.  METHOD
      must be a string, element of the list returned by
      ‘dbus-introspect-get-method-names’.  Example:
 
           (dbus-introspect-get-method
             :session "org.freedesktop.xesam.searcher"
             "/org/freedesktop/xesam/searcher/main"
             "org.freedesktop.xesam.Search" "GetHitData")
 
           ⇒ (method ((name . "GetHitData"))
                (arg ((name . "search") (type . "s") (direction . "in")))
                (arg ((name . "hit_ids") (type . "au") (direction . "in")))
                (arg ((name . "fields") (type . "as") (direction . "in")))
                (arg ((name . "hit_data") (type . "aav") (direction . "out")))
              )
 
  -- Function: dbus-introspect-get-signal-names bus service path
           interface
      Return a list of strings of all signal names of INTERFACE of
      SERVICE in D-Bus BUS at object path PATH.  Example:
 
           (dbus-introspect-get-signal-names
             :session "org.freedesktop.xesam.searcher"
             "/org/freedesktop/xesam/searcher/main"
             "org.freedesktop.xesam.Search")
 
           ⇒ ("StateChanged" "SearchDone" "HitsModified"
               "HitsRemoved" "HitsAdded")
 
  -- Function: dbus-introspect-get-signal bus service path interface
           signal
      This function returns SIGNAL of INTERFACE as XML element.  It must
      be located at SERVICE in D-Bus BUS at object path PATH.  SIGNAL
      must be a string, element of the list returned by
      ‘dbus-introspect-get-signal-names’.  Example:
 
           (dbus-introspect-get-signal
             :session "org.freedesktop.xesam.searcher"
             "/org/freedesktop/xesam/searcher/main"
             "org.freedesktop.xesam.Search" "HitsAdded")
 
           ⇒ (signal ((name . "HitsAdded"))
                (arg ((name . "search") (type . "s")))
                (arg ((name . "count") (type . "u")))
              )
