Detailed Description

The most CPU efficient Observer for the VXDTF filter tools (even if useless).

The VoidObserver is meant to be the simplest (and most useless) Observer for the VXDTF filter tools. It is notified of relevant information by the observed object via the notify method. This particular observer does not take any action to record the messages, hence the compiler will simply skip the call (in optimized compilation mode). More evolved and useful observers can derive from this one (even if not strictly necessary).
