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;
...
//do something
...
duration = c.stopClock();
std::cout<< "Duration in ms. : "<< duration <<endl;
void startClock()

Member Function Documentation

◆ isValid()

bool DGtal::Clock::isValid ( ) const

Checks the validity/consistency of the object.

Returns
'true' if the object is valid, 'false' otherwise.

◆ restartClock()

double DGtal::Clock::restartClock ( )

Restart the clock.

Returns
the time (in ms) since the last 'startClock()' or 'restartClock()'.

Referenced by test_RestartClock().

◆ selfDisplay()

void DGtal::Clock::selfDisplay ( std::ostream &  out) const

Writes/Displays the object on an output stream.

Parameters
outthe output stream where the object is written.

◆ startClock()

void DGtal::Clock::startClock ( )

Starts a clock.

Referenced by SCENARIO(), test_loopTick(), test_MultipleLoop(), and test_RestartClock().

◆ stopClock()

double DGtal::Clock::stopClock ( ) const

Stops the clock.

Returns
the time (in ms) since the last 'startClock()' or 'restartClock()'.

Referenced by test_MultipleLoop(), and test_RestartClock().
