39 * This interface handles all communication from the AudioManagerDaemon towards the system. It is designed in such a way that only callbacks with no return types are implemented. So when the CommandInterfacePlugins are designed in such a way that they broadcast signals to any node who is interested in the particular information (like signals on Dbus for example), more information can be retrieved via the CommandReceiveInterface.
\r
40 * There are two rules that have to be kept in mind when implementing against this interface:\n
\r
42 * 1. CALLS TO THIS INTERFACE ARE NOT THREAD SAFE !!!! \n
\r
43 * 2. YOU MAY NOT THE CALLING INTERFACE DURING AN SYNCHRONOUS OR ASYNCHRONOUS CALL THAT EXPECTS A RETURN VALUE.\n
\r
45 * Violation these rules may lead to unexpected behavior! Nevertheless you can implement thread safe by using the deferred-call pattern described on the wiki which also helps to implement calls that are forbidden.\n
