Detailed Description

A simple Timer class to measure execution time.

Note

We might want to extend the functionality of the timer class by making HighPrecisionTimer a template parameter. API requirements for HighPrecisionTimer class – must be default constructible – timing functions: void start() void stop() void reset() – elapsed time functions: double elapsedTimeInSec() double elapsedTimeInMilliSec() double elapsedTimeInMicroSec()

We might want to add support for pausing and resuming the timer while accumulating the time differences

Example Usage:

utilities::Timer t;
t.start();
 
// code to measure its execution time
 
t.stop();
std::cout << "Elapsed Time: << t.elapsed() << std::endl;
 
t.reset();

Constructor & Destructor Documentation

Timer()

axom::utilities::Timer::Timer ( bool  startRunning = false )
