Detailed Description

Profiles the execution time of main loop tasks.

The main loop task profiler collects samples of type MainLoopTaskProfilerSampleData, which include information about interval duration, start point, and main loop counter identifying the main loop iteration when the interval was measured.

For details on the information included in the sample, see MainLoopTaskProfilerSampleData. For an example of how the profiling sample is collected in main loop task profiling, see MainLoopTaskProfilingSampler.

The MainLoopTaskProfilerSampleData keeps samples in a circular sample buffer. Every time a new sample is added to the profiler, the statistics data is updated. To access the statistics data, use getProfilingStatistics().
