ScriptForge.Timer service

The Timer service measures the amount of time it takes to run user scripts.

A Timer measures durations. It can be:

Durations are expressed in seconds with a precision of 3 decimal digits (milliseconds). A duration value of 12.345 means 12 seconds and 345 milliseconds


A szolgáltatás igénybevétele

Before using the Timer service the ScriptForge library needs to be loaded or imported:

note

• Basic macros require to load ScriptForge library using the following statement:
GlobalScope.BasicLibraries.loadLibrary("ScriptForge")

• Python scripts require an import from scriptforge module:
from scriptforge import CreateScriptService


A Basic nyelvben

The example below creates a Timer object named myTimer and starts it immediately.


    GlobalScope.BasicLibraries.LoadLibrary("ScriptForge")
    Dim myTimer As Variant
    myTimer = CreateScriptService("Timer", True)
    'The timer starts immediately when the second argument = True, default = False
  

It is recommended to free resources after use:


    Set myTimer = myTimer.Dispose()
  
A Python nyelvben

    from scriptforge import CreateScriptService
    myTimer = CreateScriptService("Timer", start = True)
    # ...
    myTimer = myTimer.Dispose()

Típus

Leírás

Duration

Igen

Double

The actual running time elapsed since start or between start and stop (does not consider suspended time)

IsStarted

Igen

Boolean

True when timer is started or suspended

IsSuspended

Igen

Boolean

True when timer is started and suspended

SuspendDuration

Igen

Double

The actual time elapsed while suspended since start or between start and stop

TotalDuration

Igen

Double

The actual time elapsed since start or between start and stop (including suspensions and running time)


Tipp ikon

Note that the TotalDuration property is equivalent to summing the Duration and SuspendDuration properties.


Metódusok

All methods do not require arguments and return a Boolean value.

If the returned value is False, then nothing happened.

Continue

Resumes the Timer if it has been suspended

False if the timer is not suspended

Restart

Terminates the Timer and discards its current property values, restarting as a new clean Timer

False if the timer is inactive

Start

Starts a new clean timer

False if the timer is already started

Suspend

Suspends a running timer

False if the timer is not started or already suspended

Terminate

Stops a running timer

False if the timer is neither started nor suspended


Példa:

The examples below in Basic and Python illustrate the use of the methods and properties in the Timer service.

A Basic nyelvben

    myTimer.Start()
    Wait 500
    myTimer.Suspend()
    'The time elapsed while the Dialog box is open will be counted as suspended time
    MsgBox myTimer.Duration & " " & myTimer.SuspendDuration & " " & myTimer.TotalDuration
    myTimer.Continue()
    Wait 500
    'The time elapsed while the Dialog box is open will be counted as running time
    MsgBox myTimer.Duration & " " & myTimer.SuspendDuration & " " & myTimer.TotalDuration
    myTimer.Terminate()
    'Shows the final time measurements
    MsgBox myTimer.Duration & " " & myTimer.SuspendDuration & " " & myTimer.TotalDuration
  
note

Ha a Terminate metódust hívja meg, a Continue metódus későbbi hívásai nem folytatják az időmérést. Hasonlóképpen, miután egy időzítő megszűnt, a Start metódus hívása újraindítja azt, mintha egy tiszta új időzítő lenne.


A Python nyelvben

    from time import sleep
    bas = CreateScriptService("Basic")
    myTimer.Start()
    sleep(0.5)
    myTimer.Suspend()
    bas.MsgBox("{} {} {}".format(myTimer.Duration, myTimer.SuspendDuration, myTimer.TotalDuration))
    myTimer.Continue()
    sleep(0.5)
    bas.MsgBox("{} {} {}".format(myTimer.Duration, myTimer.SuspendDuration, myTimer.TotalDuration))
    myTimer.Terminate()
    bas.MsgBox("{} {} {}".format(myTimer.Duration, myTimer.SuspendDuration, myTimer.TotalDuration))
  
note

Be aware that the Wait function in BASIC takes in a duration argument in milliseconds whereas the sleep function in Python uses seconds in its argument.


Working with Multiple Timers

It is possible to instantiate multiple Timer services in parallel, which gives flexibility in measuring time in different parts of the code.

The following example illustrates how to create two Timer objects and start them separately.

A Basic nyelvben

    Dim myTimerA as Variant, myTimerB as Variant
    myTimerA = CreateScriptService("Timer")
    myTimerB = CreateScriptService("Timer")
    ' myTimerA elkezdése
    myTimerA.Start()
    Wait 1000 'Wait 1 second (1,000 milliseconds)
    MsgBox myTimerA.Duration & " " & myTimerB.Duration
    ' myTimerB elkezdése
    myTimerB.Start()
    Wait 1000
    MsgBox myTimerA.Duration & " " & myTimerB.Duration
    'Mindkét időzítő leállítása
    myTimerA.Terminate()
    myTimerB.Terminate()
  
A Python nyelvben

    from time import sleep
    myTimerA = CreateScriptService("Timer")
    myTimerB = CreateScriptService("Timer")
    myTimerA.Start()
    sleep(1)
    bas.MsgBox("{} {}".format(myTimerA.Duration, myTimerB.Duration))
    myTimerB.Start()
    sleep(1)
    bas.MsgBox("{} {}".format(myTimerA.Duration, myTimerB.Duration))
    myTimerA.Terminate()
    myTimerB.Terminate()
