Remarks

The source levels identify the TraceEventType events that are to be traced. The SourceSwitch class uses the SourceLevels enumeration to define the event level of the trace message to use for filtering messages to send to the trace listener.

The EventTypeFilter class uses the SourceLevels enumeration to determine whether a trace listener should emit a trace.
