Detailed Description

The interface towards the Controlling Instance (e.g HMI).

It handles the communication towards the HMI and other system components who need to interact with the audiomanagement. There are two rules that have to be kept in mind when implementing against this interface:

Warning
  1. CALLS TO THIS INTERFACE ARE NOT THREAD SAFE !!!!
  2. YOU MAY NOT CALL THE CALLING INTERFACE DURING AN SYNCHRONOUS OR ASYNCHRONOUS CALL THAT EXPECTS A RETURN VALUE.

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.
For more information, please check CAmSerializer
