Preconfiguration "Periodic time scheduler for running programmed tasks."
This preconfiguration can be activated when creating a new object (e.g. by
"New object ..." in the local object menu or by pressing the
Insert key after selecting the object) and is included in the group:
"/ Technology / Schedulers".
- The preconfiguration creates an object of the
PmaFolder type. The main object name is preconfigured to
"TaskScheduler".
- The preconfiguration is created including the panel (object of the
PmaPanel type) is functional also as
Web panel.
Preconfiguration of
PmaFolder with preconfigured objects
PmaPanel,
PmaDataTable and
PmaFolder
The
Panel contains a table (
PmfTable) with controls that can be used to periodically set the repetition of a task (subfolders of
Tasks). This can be done once or multiple times in the range of an hour (day, week or month).
The tasks themselves are programmed in
PmaFolder objects, which are subfolders of the
Tasks object. They have a user interface represented by the
GetParams and
Call methods.
The GetParams method publishes a list of usable parameters for the Call method.
The Call method then programs the desired task using the parameter if applicable.
The number of objects is not limited and each object can be programmed for a different desired task.
The
PmaDataTable object is used for continuous running of planned tasks. And also to store and retrieve the required task configuration. It is also used for saving the configuration state to a file in
json format and reloading it.
These configurators can be set before the preconfiguration is created:
| The name of created object | Name of the object created in the tree of Pma objects. The maximum name length is 30 characters. This is a system name, so it must contain only alphanumeric and must not contain any diacritics (i.e. national dependent chars), empty string, spaces and the first character must not be a number.
Default: "TaskScheduler" |

|
| Enable as Web component | Specifies whether this object has to be registered as a Web server component
After the preconfiguration is created, the "PmaPanel > Web server > Enable as Web component" configurator will be set to this value. |
|---|
| PmaWeb object | Path in the tree of Pma objects to the object PmaWeb, PmaWebFolder or PmaWebLang where the registration is carried out.
Macro expression can be used for input (it is evaluated after starting the application).
After the preconfiguration is created, the "PmaPanel > Web server > PmaWeb object" configurator will be set to this value. |
