Hinweise

The TraceReader class provides trace data reading functionality and access to data that is common to both the TraceServer class, the TraceTable class, and the TraceFile class.

The trace data reading functionality is also available on the TraceReaderWriter class, which is derived from the TraceReader class and is used in the construction of the TraceTable class and TraceFile class.
