Detailed Description

Implements a timer mechanism that captures the wall clock, user time and system time that occur while the timer is running.

Constructor & Destructor Documentation

RWQETimer::RWQETimer ( )

inline

Constructs a new timer. The timer does not start running until start() is called.

Member Function Documentation

uint64_t RWQETimer::getElapsedSystemTime ( ) const

inline

The elapsed system time.

uint64_t RWQETimer::getElapsedUserTime ( ) const

inline

The elapsed user time.

uint64_t RWQETimer::getElapsedWallTime ( ) const

inline

The elapsed wall clock time.

void RWQETimer::reset ( )

inline

Reset the timer to 0.

static void RWQETimer::snapshot ( uint64_t *  system, uint64_t *  user, uint64_t *  wall  )

staticprivate

Utility function that returns the current snapshot time point for the requested values with millisecond precision.

void RWQETimer::start ( )

inline

Puts the timer in the "running" state. Time accumulates while in this state.

void RWQETimer::stop ( )

inline

Puts the timer in the "stopped" state. Time does not accumulate while in this state.
