The tool allows you to measure the time taken to execute a specific code segments. The tool only uses the standard library given in C++11 standard.
The library is in a single header file that can be included in any project that atleast uses C++ 11 standards.
Measuring the execution times of the code segments.
// include metric.h in the files where you would like to measure the execution time.
#include "metric.h"
// surround the code segment with the following lines
// Start the timer by declaring an object and give the operation a name so
// that multiple run's of the code segment could be used to calculate the min, max and avg runtimes.
metric::Timer timer1("Name of the operation");
// Code segment to be tested
// This stops the timer and adds the duration taken for executing code segment to the
// the average calculation.
timer1.stop();Printing the execution times in the main executable.
// include the metric.h
#include "metric.h"
// At the end of the excutable after all the timers have completed measuring execution time.
// Print the timer results.
// Print the results in hours:minutes:seconds:milliseconds
metric::TimerManager::print();
// Print the results in milliseconds
metric::TimerManager::print(true);An example can be seen in test.cpp.
This tool is based on the excellent sm_timing. But it depends on the boost library and including the boost library to use sm_timing is inefficient. Hence, this tool was written to work without the boost library.
