Object PmaTimer (Timer)

Description:

The object watches the time period expiration. The onTick event is triggered with the certain period. The object is suitable first of all for periodic execution of the script or its execution in the daytime. It is possible to perform event larger functionality as for example the late execution of the script (see StartEx method). It is better to perform the more common way of time control by the PmaSequencer object.

No other Pma objects can be created in this object.
This object can be created in objects: PmaRoot, PmaFolder, PmaPrototype. Multiple objects of this type can be created in such objects.

Periods of triggering the onTick event can be changed on an ongoing basis (see Period property) or disabled on an ongoing basis (see Enabled property).
The period is entered in seconds but as it is of the Double type, it is possible to enter the time unit smaller than 1 second. The object is linked to the computer time that "ticks" with the maximum period of 10 ms (i.e. 0.01 second). But practically such short periods cannot be used in this object. It is also recommended not to use very small value because it puts higher performance load in the application.

This object inherits properties, methods and events of the PmaObject object.

Properties and methods of this object:

Counter	Counter restricting the number of runs
Emulate()	Tick emulation
Enabled	Enable/disable the timer
LastTick	Time of last triggering of the onTick event
Period	Timer period in seconds
StartEx()	Timer activation with the specified number of runs and the period

Root	Returns reference to the root application object PmaRoot

Events of this object:

onTick	Is triggered after every timer tick

Events inherited from the PmaObject object:
