|
|
*
|
|
* This module contains the code for dealing with the get, set, and
|
|
* instance name routines for the HrStorage. 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.
