Detailed Description

A timer for measuring performance of code and dumping the results to a file.

e.g.

PerformanceCounter pc ("fish", 50, "/temp/myfishlog.txt");

for (;;)
{
    pc.start();

    doSomethingFishy();

    pc.stop();
}

In this example, the time of each period between calling start/stop will be measured and averaged over 50 runs, and the results printed to a file every 50 times round the loop.

Constructor & Destructor Documentation

PerformanceCounter()

PerformanceCounter::PerformanceCounter	(	const String &	counterName,
		int	runsPerPrintout = 100,
		const File &	loggingFile = File()
	)

Creates a PerformanceCounter object.

Parameters

counterName	the name used when printing out the statistics
runsPerPrintout	the number of start/stop iterations before calling printStatistics()
loggingFile	a file to dump the results to - if this is File::nonexistent, the results are just written to the debugger output

~PerformanceCounter()

PerformanceCounter::~PerformanceCounter

(

)

Destructor.

Member Function Documentation

getStatisticsAndReset()

PerformanceCounter::Statistics PerformanceCounter::getStatisticsAndReset

(

)

Returns a copy of the current stats, and resets the internal counter.

printStatistics()

void PerformanceCounter::printStatistics

(

)

Dumps the current metrics to the debugger output and to a file.

As well as using Logger::outputDebugString to print the results, this will write then to the file specified in the constructor (if this was valid).

start()

void PerformanceCounter::start ( )

noexcept

Starts timing.

stop

stop()

bool PerformanceCounter::stop

(

)

Stops timing and prints out the results.

The number of iterations before doing a printout of the results is set in the constructor.
