Detailed Description

Abstract interface to observe the BackgroundTask.

Note: since the BackgroundTask is accessed from different threads, there is no guarantee from which thread the observer is called. It may even be called from multiple threads simultaneously. The main idea of having this Observer is to implement different logging facilities.
