Methods and signals are the communication means to D-Bus. The following functions return their specifications.
This function returns 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")
This function returns method of interface as an XML
element. It must be located at service in D-Bus bus at
object path path. method must be a string and a member 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"))))
This function returns 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")
This function returns signal of interface as an XML
element. It must be located at service in D-Bus bus at
object path path. signal must be a string and a member 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"))))
