Detailed Description

Description of class 'Clock'

Aim: To provide functions to start and stop a timer. Is useful to get performance of algorithms.

The following code snippet demonstrates how to use Clock

#include <DGtal/base/Clock.h>
 
 Clock c;
 long duration;
 
 c.startClock();
 ...
 //do something
 ...
 duration = c.stopClock();
 
 std::cout<< "Duration in ms. : "<< duration <<endl;
