Detailed Description

The timer class provides a way for mlpack methods to be timed.

The three methods contained in this class allow a named timer to be started and stopped, and its value to be obtained. A named timer is specific to the thread it is running on, so if you start a timer in one thread, it cannot be stopped from a different thread.

DisableTiming()

static void DisableTiming ( )

static

Disable timing of mlpack programs.

Do not run this while timers are running!

EnableTiming()

static void EnableTiming ( )

static

Enable timing of mlpack programs.

Do not run this while timers are running!

Referenced by mlpack::util::EnableTimers(), mlpack::util::GetParamWithInfo(), and main().

Get()

static std::chrono::microseconds Get ( const std::string &  name )

static

Get the value of the given timer.

Parameters

name	Name of timer to return value of.

Referenced by Timers::Timers().

GetAllTimers()

static std::map<std::string, std::chrono::microseconds> GetAllTimers ( )

static

Returns a copy of all the timers used via this interface.

Referenced by mlpack::bindings::cli::EndProgram(), and Timers::Timers().

ResetAll()

static void ResetAll ( )

static

Stop and reset all running timers.

This removes all knowledge of any existing timers.

Referenced by mlpack::util::GetParamWithInfo(), and mlpack::util::ResetTimers().

Start()

static void Start ( const std::string &  name )

static

Start the given timer.

If a timer is started, then stopped, then re-started, then re-stopped, the final value of the timer is the length of both runs – that is, mlpack timers are additive for each time they are run, and do not reset.

Note

A std::runtime_error exception will be thrown if a timer is started twice.

Parameters

name	Name of timer to be started.

Referenced by Timers::Timers().

Stop()

static void Stop ( const std::string &  name )

static

Stop the given timer.

Note

A std::runtime_error exception will be thrown if a timer is started twice.

Parameters

name	Name of timer to be stopped.
