Member Function Documentation
| virtual double ork::Timer::end | ( | ) | [virtual] |
Returns the delay since the last call to start() in micro seconds.
Reimplemented in ork::GPUTimer.
| virtual double ork::Timer::getAvgTime | ( | ) | [virtual] |
Returns the average delay at every call to end() in micro seconds.
This won't be accurate if the timer is not stopped.
Reimplemented in ork::GPUTimer.
| double ork::Timer::getCurrentTime | ( | ) | [protected] |
Returns the current time in microseconds.
The origin of time may depend on the platform.
| static void ork::Timer::getDateString | ( | char * | buffer, | |
| int | bufSize | |||
| ) | [static] |
Get a string based on the current date.
Buffer must be of sufficient length. Format YYYY.MM.DD
| static void ork::Timer::getDateTimeString | ( | char * | buffer, | |
| int | bufSize | |||
| ) | [static] |
Get a string based on the current date and time of the day.
Buffer must be of sufficient length. Format YYYY.MM.DD.HH.MM.SS
| double ork::Timer::getMaxDuration | ( | ) | const |
| double ork::Timer::getMinDuration | ( | ) | const |
| int ork::Timer::getNumCycles | ( | ) | const |
Returns the number of calls to start since last reset().
| virtual double ork::Timer::getTime | ( | ) | [virtual] |
Returns the delay recorded at the last end() call.
Reimplemented in ork::GPUTimer.
| static void ork::Timer::getTimeOfTheDayString | ( | char * | buffer, | |
| int | bufSize | |||
| ) | [static] |
Get a string based on the current time of the day.
Buffer must be of sufficient length. Format HH.MM.SS
| virtual void ork::Timer::reset | ( | ) | [virtual] |
Resets the statistics (total, average, min, and max durations).
| virtual double ork::Timer::start | ( | ) | [virtual] |
Starts this timer and returns the current time in micro seconds.
Reimplemented in ork::GPUTimer.
