ChronoTimer

This is a simple stopwatch class. The main purpose of this class is to enable a developer to estimate a performance of hotspots in their C++ code.

Requrements:

• Operating system on Linux
• Compiler what support C++ 17

Installation:

Clone repository somewere and perform commands:

cd ./ChronoTimer
cmake ./CMakeLists.txt
make install

Example of usage:

#include<iostream>
#include<mutex>
#include<sstream>
#include"chronotimer.h"usingnamespacestd;// Measured functionautoTestFunction() {
cout << "Im a test function! Hello World!" << endl;
size_t n = 1'000'000;
do{
n--;
}while(n>0);
return"Well done!";
}
// Measured function with argumentsautoTestFunctionWithArg(std::string ret) {
cout << "Im a test function With arguments!" << endl;
size_t n = 2'000'000;
do{
n--;
}while(n>0);
return ret;
}
intmain() {
// Example of usage 1
{
Estimate::ChronoTimer timer(TestFunction);
cout << timer.Run() << endl << timer.GetTime<>() << endl;
}
// Example of usage 2
{
cout << Estimate::ChronoTimer(TestFunction).RunAndPrint(cout) << endl;
}
// Example of usage 3
{
Estimate::ChronoTimer timer(TestFunctionWithArg,"Good args!");
cout << timer.Run() << endl << timer.GetTime<>() << endl;
}
// Example of usage 4
{
cout << Estimate::ChronoTimer(TestFunctionWithArg,"Good args!").RunAndPrint(cout) << endl;
}
return0;
