TraceReaderWriter Class

Definition

The TraceReaderWriter class is an abstract Trace Objects class that is used in the construction of the TraceTable class and the TraceFile class.

Remarks

The TraceReaderWriter class provides trace data writing functionality that is common to both the TraceTable class and the TraceFile class.
