mrpt::system::CTimeLogger Class Reference

Detailed Description

A versatile "profiler" that logs the time spent within each pair of calls to enter(X)-leave(X), among other stats.

The results can be dumped to cout or to Visual Studio's output panel. This class can be also used to monitorize min/mean/max/total stats of any user-provided parameters via the method CTimeLogger::registerUserMeasure().

Optional recording of all data can be enabled via enableKeepWholeHistory() (use with caution!).

Cost of the profiler itself (measured on MSVC2015, Windows 10, Intel i5-2310 2.9GHz):

CTimeLoggerEntry
Note
The default behavior is dumping all the information at destruction.
