+Every time when CLogServOperationQueue::RunL() takes the execution control, an operation will be picked up
+from the pending queue and the StartL() method of the operation - called, for example: 
+CLogServOpEventAdd::StartL(). The operation's StartL() method will read the client data and calls an
+appropriate method from this interface - TaskEventAddL() for example.
