callMethod Source

Arguments

:: Text	Entity to send the message to
-> ObjectPath	Object
-> Text	Interface
-> Text	Member (method) name
-> [SomeDBusValue]	Arguments
-> [Flag]	Method call flags
-> DBusConnection	Connection to send the call over
-> IO (STM (Either [SomeDBusValue] SomeDBusValue))

Asychronously call a method. Returns an STM action that waits for the returned value.

getAnswer :: IO (STM b) -> IO b Source

Wait for the answer of a method call

callMethod' Source

Arguments

:: (SingI (RepType a), Representable a, MonadThrow m, MonadIO m)
=> Text	Entity to send the message to
-> ObjectPath	Object
-> Text	Interface
-> Text	Member (method) to call
-> [SomeDBusValue]	Arguments
-> [Flag]	Method call flags
-> DBusConnection	Connection to send the call over
-> m a

Synchronously call a method. Returned errors are thrown as MethodErrors. If the returned value's type doesn't match the expected type a MethodSignatureMissmatch is thrown.
