Detailed Description#

a Class to measure passing time.

The class computes passing time by counting the number of ticks per second. That is, the following code computes the execution time in seconds:

        TickMeter tm;
        tm.start();
        // do something ...
        tm.stop();
        cout << "Total time: " << tm.getTimeSec() << endl;

It is also possible to compute the average time over multiple runs:

        TickMeter tm;
        for (int i = 0; i < COUNT; i++)
        {
            tm.start();
            // do something ...
            tm.stop();
            cout << "Last iteration: " << tm.getLastTimeSec() << endl;
        }
        cout << "Average time per iteration in seconds: " << tm.getAvgTimeSec() << endl;
        cout << "Average FPS: " << tm.getFPS() << endl;
