Detailed Description

This class is used for profiling purposes in Guiliani.

You can measure the following things during runtime:

  • CPU

The CPU value is calculated by taking two different time-spans (processing time / complete time for one loop) The first one is the time which internal processing in Guiliani takes up. This one does not include acquiring new events from the InputDevice. This is done because, when there is no event the InputDevice will wait for a timeout. The second value is the time which elapses for the complete run.

So the term CPU-consumption might not be the correct one, since in a multi-tasking environment the scheduler might split one loop of Guiliani into several small parts, which are interrupted by other tasks. It is more like a percentage of the whole timeslice Guiliani has had to the part of the timeslice for processing. So 50% means that 50% of the time inside the Guiliani main-loop was spent for the input-device and 50% for processing, whereas 100% means that there was nearly no time consumed by waiting for events.

  • FPS

There are two different values for the FPS of Guiliani: 1. FPS measures only the time for redrawing the invalidated regions on the screen. This value may get really high if there is nothing to be drawn on the screen.

2. AbsFPS measures the time for a whole cycle through the main-loop of Guiliani, including processing time of internal stuff (Commands, DataPool, etc.) This value is comparable to the FPS-value you are used from games or other applications.

  • Memory

There a several measurements for memory-profiling available: 1. used memory the number of bytes currently used by allocation in Guiliani

2. maximum value for allocated memory 3. largest block ever allocated these two values can be reset during runtime for analyzing different situations

4. number of allocated blocks

Note: please keep in mind that only memory which is allocated by new/delete is counted. if you use the C-functions malloc/free the memory will not be tracked by the profiler.

It is also possible to display a bar of the consumed memory on the screen, where the color of the bar indicated if a threshold (which can be set seperately) was reached. The length of the bar is the total amount of memory available. The colored bar (green, yellow, red) indicates the currently used memory. The blue bar in the background indicates the maximum amount of allocated memory.

  • Graphics

for measuring graphics performance in various situations the duration of redraw and refresh are calculated and can be displayed during runtime.

◆ DoAnimate()

virtual void CGUIProfiler::DoAnimate ( const eC_Value &  vTimes = eC_FromInt(1))
virtual

Called when the timer of an animation callback belonging to this animatable has expired.

Parameters
vTimesThe factor of the registered callback time in relation to the actually elapsed time. For example, the elapsed time is 80ms, and the standard time is 50ms, then vTimes is 1.6. If the given time in GETTIMER.AddAnimationCallback is 0, It will be set to -1.
