public abstract class AbstractAsynchrounousSampleObserver
extends AbstractWorkerThread
implements AsynchrounousSampleObserver

Abstract base class for asynchronous working sample observer components, which do depend on the service life cycle.

Main features:

• can be attached as observer for samples,
• does maintain an event collector to store observed samples in a thread safe queue for further processing,
• does run asynchronously as daemon worker thread,
• does implement the life cycle object behavior.

Can be extended to implement a specific kind of sample data processing in the AbstractWorkerThread.doWork() method of the thread.
