Detailed Description

The MonitorTimer keeps track of the time when to emit monitor data.

Member Typedef Documentation

Clock

using Utopia::DataIO::MonitorTimer::Clock = std::chrono::high_resolution_clock

Data type for the clock.

DurationType

using Utopia::DataIO::MonitorTimer::DurationType = std::chrono::duration< double >

Data type for the time unit.

Time

using Utopia::DataIO::MonitorTimer::Time = std::chrono::high_resolution_clock::time_point

Data type for a time point.

Constructor & Destructor Documentation

MonitorTimer()

Utopia::DataIO::MonitorTimer::MonitorTimer ( const double  emit_interval )

inline

Constructor.

Construct a new Monitor Timer object. The _last_emit time is set to the time of construction.

Parameters

emit_interval

The time interval that defines whether the time has come to emit data. If more time than the _emit_interval has passed the time_has_come function returns true.

Member Function Documentation

get_emit_interval()

const DurationType Utopia::DataIO::MonitorTimer::get_emit_interval ( ) const

inline

Return the emit interval.

get_time_elapsed()

template<class DurationT = DurationType>

const DurationT Utopia::DataIO::MonitorTimer::get_time_elapsed ( ) const

inline

Get the time elapsed since the start of this timer.

get_time_elapsed_seconds()

double Utopia::DataIO::MonitorTimer::get_time_elapsed_seconds ( ) const

inline

Get the time elapsed since start of this timer, converted to seconds.

reset()

void Utopia::DataIO::MonitorTimer::reset ( )

inline

Reset the timer to the current time.

time_has_come()

bool Utopia::DataIO::MonitorTimer::time_has_come ( ) const

inline

Check for whether the time to emit has come or not.

Parameters

reset

Reset the internal timer to the current time if the _emit_interval has been exceeded.

Returns

true if the internal timer has exceeded the _last_emit time.

Member Data Documentation

_emit_interval

const DurationType Utopia::DataIO::MonitorTimer::_emit_interval

private

The emit interval.

_last_emit

Time Utopia::DataIO::MonitorTimer::_last_emit

private

The time of the last emit.

_start_time

const Time Utopia::DataIO::MonitorTimer::_start_time

private

The starting time of the timer.
