* Abstract:
*
* This module contains the code for dealing with the get, set, and
* instance name routines for the HrSWRunPerfEntry. Actual instrumentation code is
* supplied by the developer.
*
* Functions:
*
* A get and set routine for each attribute in the class.
*
* The routines for instances within the class.
