Detailed Description

RWTraceSingleClientFilterImp is a filter implementation that accepts one client to which it forwards trace events. This class is intended to be the base class for filters that accept one client and is not intended to be directly instantiated.

Attempting to add a client if the filter already has one throws an RWTraceClientAlreadyAdded exception.
