Detailed Description

A Chronograph for measuring time spent in code. Each instance of this class accumulates time spent by your program between calls to start() and stop(). The time can then be retrieved by elapsedTimeXXX() methods.

Example:

    Chronograph c;
    c.start();
    for(int i=0; i<10000; ++i) { / * do stuff * / }
    c.stop();
    cout << "Spent = " << c.elapsedTimeInSec() << " seconds" << endl;

Constructor & Destructor Documentation

sword::Chronograph::Chronograph (    )

Creates a Chronograph. The time measurement is not started yet. You must call start() once to start the chronograph.

Member Function Documentation

void sword::Chronograph::clear (    )

Clear (reset) the Chronograph. The accumulated elapsed time is lost, and you have to call start() again to start measuring again

word32 sword::Chronograph::elapsedTimeInMillis (    )

Get the accumulated time in milliseconds. This method can be called either 'during measurement' (between a start() and a stop() ), or 'post morten' (after a stop() ). See also: elapsedTimeInSec, start, stop

double sword::Chronograph::elapsedTimeInSec (    )

Get the accumulated time in seconds.

void sword::Chronograph::start (    )

Start measuring time. See also: start, elapsedTimeInMillis, elapsedTimeInSec

void sword::Chronograph::stop (    )

Stop measuring time. The time elapsed between the last call to start() and this call is accumulated in the chronograph See also: start, elapsedTimeInMillis, elapsedTimeInSec
