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. Recursive methods are supported with no problems, that is, calling "enter(X) enter(X) ... leave(X) leave(X)". enter()/leave() are thread-safe.

This class can be also used to monitorize min/mean/max/total stats of any user-provided parameters via the method CTimeLogger::registerUserMeasure()

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

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