dbus: Arguments and Signatures

 
 2.7 The final details.
 ======================
 
 Methods and signals have arguments.  They are described in the ‘arg’ XML
 elements.
 
  -- Function: dbus-introspect-get-argument-names bus service path
           interface name
      Return a list of all argument names as list of strings.  NAME must
      be a ‘method’ or ‘signal’ XML element.  Example:
 
           (dbus-introspect-get-argument-names
             :session "org.freedesktop.xesam.searcher"
             "/org/freedesktop/xesam/searcher/main"
             "org.freedesktop.xesam.Search" "GetHitData")
 
           ⇒ ("search" "hit_ids" "fields" "hit_data")
 
      Argument names are optional; the function can return ‘nil’
      therefore, even if the method or signal has arguments.
 
  -- Function: dbus-introspect-get-argument bus service path interface
           name arg
      Return argument ARG as XML object.  NAME must be a ‘method’ or
      ‘signal’ XML element.  Example:
 
           (dbus-introspect-get-argument
             :session "org.freedesktop.xesam.searcher"
             "/org/freedesktop/xesam/searcher/main"
             "org.freedesktop.xesam.Search" "GetHitData" "search")
 
           ⇒ (arg ((name . "search") (type . "s") (direction . "in")))
 
  -- Function: dbus-introspect-get-signature bus service path interface
           name &optional direction
      Return signature of a ‘method’ or ‘signal’, represented by NAME, as
      string.
 
      If NAME is a ‘method’, DIRECTION can be either ‘in’ or ‘out’.  If
      DIRECTION is ‘nil’, ‘in’ is assumed.
 
      If NAME is a ‘signal’, and DIRECTION is non-‘nil’, DIRECTION must
      be ‘out’.  Example:
 
           (dbus-introspect-get-signature
             :session "org.freedesktop.xesam.searcher"
             "/org/freedesktop/xesam/searcher/main"
             "org.freedesktop.xesam.Search" "GetHitData" "in")
 
           ⇒ "sauas"
 
           (dbus-introspect-get-signature
             :session "org.freedesktop.xesam.searcher"
             "/org/freedesktop/xesam/searcher/main"
             "org.freedesktop.xesam.Search" "HitsAdded")
 
           ⇒ "su"
