Detailed Description

Record and report elapsed real time ("clock" or "wall" time) in seconds.

Constructor & Destructor Documentation

◆ Stopwatch()

OpenSim::Stopwatch::Stopwatch ( )
inline

This stores the start time as the current time.

References reset().

Member Function Documentation

◆ formatNs()

static std::string OpenSim::Stopwatch::formatNs ( const long long &  nanoseconds)
inlinestatic

Format the provided elapsed time in nanoseconds into a string.

The time may be converted into seconds, milliseconds, or microseconds. Additionally, if the time is greater or equal to 60 seconds, the time in hours and/or minutes is also added to the string. Usually, you can call getElapsedTimeFormatted() instead of calling this function directly. If you call this function directly, use getElapsedTimeInNs() to get a time in nanoseconds (rather than getElapsedTime()).

◆ getElapsedTime()

double OpenSim::Stopwatch::getElapsedTime ( ) const
inline

Return the amount of time that has elapsed since this object was constructed or since reset() has been called.

◆ getElapsedTimeFormatted()

std::string OpenSim::Stopwatch::getElapsedTimeFormatted ( ) const
inline

This provides the elapsed time as a formatted string (using format()).

References formatNs(), and getElapsedTimeInNs().

◆ getElapsedTimeInNs()

long long OpenSim::Stopwatch::getElapsedTimeInNs ( ) const
inline

Get elapsed time in nanoseconds.

See SimTK::realTimeInNs() for more information.
