The example application

 

The example application is a great way to explore the capabilities of Performance Validator.

 

The source and projects are included in the installation, but you'll need to build the example application yourself.

 

You can then use nativeExample.exe in conjunction with Performance Validator to monitor the performance of the application as you use it.

How to use these examples

 

The best way to understand how Performance Validator works is by example.

 

We recommend launching the example application from Performance Validator and observing how the menu actions affect performance statistics and hotspots.

 

Examining the source code is the best way to see what's going on in the example application.

 

Resetting the statistics before and between using the menu items is a good way to easily see exactly what new code was marked as being time consuming.

 

The example runs some inline tests and some sorting methods. For convenience, below we have provided the source locations where each menu action runs a test.

 

Most test locations are in the CMainFrame class of nativeExample\mainfrm.cpp

 

 

File menu

instructionStep Test inline classes

OnFileTestinlineclasses()

Calls a small number of in-lined functions in a tight loop.

seeAlsoSee the comment in this function for details about in-line functions and the data collection mode.

instructionStep Exit

closes the example application

 

 

Sort menu

 

All the sorting routines populate an array with a certain number of items and then validate the result after sorting the array.

instructionStep Quick Sort

OnSortQuicksort()

sorts an array using qsort

instructionStep Comb Sort

OnSortCombsort()

sorts an array using doCombSort

instructionStep Heap Sort

OnSortHeapsort()

sorts an array using heapSort

instructionStep Merge Sort

OnSortMergesort()

sorts an array using mergeSort_sortCore

instructionStep Bubble Sort

OnSortBubblesort()

sorts an array using quite an inefficient algorithm

instructionStep Choose how many items to sort...

OnSortChoosehowmanyitemstosort()

sets the number of items being sorted by each of the above methods
