Detailed Description

Clock class.

This class is used for measuring time in PTF. The implementation tries to use the best timer available for the system. On Linux the POSIX realtime clock is used. On MacOS X it is the Mach timer.

Member Function Documentation

void Clock::calculateClockResolution (  timespec &  tspec  )

Calculate the resolution of the clock. Most systems report a false clock resolution. So here it is calculated. The resolution is the value that is added when the clock changes. Parameters: tspec  a timespec structure which will store the clock resolution Definition at line 136 of file clock.cpp. References getClock(). Referenced by Clock(). Here is the call graph for this function:

void Clock::getClock (  timespec &  tspec  )

Get time and write it to a timspec structure. Parameters: tspec  timspec structure which the time will be written to Definition at line 102 of file clock.cpp. References PtfCore::getMessageLog(), and Singleton< PtfCore >::getSingleton(). Referenced by calculateClockResolution(), TimeInterval::measureA(), and TimeInterval::measureB(). Here is the call graph for this function:
