Constructor & Destructor Documentation

makVrv::DtInMemoryProfiler::DtInMemoryProfiler ( )

CTOR Max number of samples to be collected must be provided up front, so that mem allocations don't take up profiling time.

makVrv::DtInMemoryProfiler::~DtInMemoryProfiler ( )

DTOR.

Member Function Documentation

static std::size_t makVrv::DtInMemoryProfiler::calculateNumberOfSamples	(	float	estimatedFrequency,
		float	estimatedRunTimeSeconds
	)

static

Utility function: Given an approximate frequency and a run time in seconds will compute the upper bound on the number of samples needed.

void makVrv::DtInMemoryProfiler::init	(	std::size_t	numOfSamples,
		const std::string &	fileName
	)

std::size_t makVrv::DtInMemoryProfiler::numSamples ( ) const

Max number of samples that the profiler can profile.

void makVrv::DtInMemoryProfiler::start ( )

Start profiling (a given frame)

void makVrv::DtInMemoryProfiler::stop ( )

Stop profiling (a given frame)

void makVrv::DtInMemoryProfiler::reset ( )

discard current samples profiled (e.g. to start profiling anew)

bool makVrv::DtInMemoryProfiler::dumped ( ) const

were stats dumped already? This can happen if the number of samples to be collected exceed the capacity

void makVrv::DtInMemoryProfiler::dump ( )

bool makVrv::DtInMemoryProfiler::valid ( ) const

Is profiler valid. Will be false if it cannot allocate memory for requested number of samples or if the dump file cannot be written to, etc.

void makVrv::DtInMemoryProfiler::dumpStats ( )

protected

dump the min/max/and average
