Validation: IMetabaseObjectDescriptor
The Validation property determines the validation rule, on executing of which the task is performed.
The property is relevant if IScheduledTask.CreateChecker = ScheduledTaskCheckerType.Validation.
Executing the example requires:
Scheduled tasks container with the TASK_CONTAINER identifier that contains a task.
Time series database with the RUBRICATOR identifier containing validation rule with the VALIDATION identifier.
Add links to the Metabase, Fore system assemblies.
Sub UserProc;
Var
MB: IMetabase;
cont: IScheduledTasksContainer;
task: IScheduledTask;
TChecker: IScheduledTaskChecker;
ValidationChecker: IScheduledTaskValidationChecker;
Begin
MB := metabaseClass.Active;
cont := MB.ItemById("TASK_CONTAINER").Edit As IScheduledTasksContainer;
task := cont.Tasks.Item(0).Edit As IScheduledTask;
TChecker := task.CreateChecker(ScheduledTaskCheckerType.Validation);
ValidationChecker := TChecker As IScheduledTaskValidationChecker;
Debug.WriteLine("Task execution condition is set: ");
Select Case (TChecker.Type As Integer)
Case 0: Debug.WriteLine(" - Execute task if function is performed with result");
Case 1: Debug.WriteLine(" - Execute task if validation rule is performed with result");
End Select;
ValidationChecker.Validation := MB.ItemByIdNamespace("VALIDATION", MB.ItemById("RUBRICATOR").Key).Bind;
ValidationChecker.Condition := STValidationCheckerConditionType.Equal;
ValidationChecker.ExceptionCount := 0;
task.TaskChecker := TChecker;
(task As IMetabaseObject).Save;
End Sub UserProc;
After executing the example, task execution setup conditions are set:
The Perform the Task if Validation Rule is Executed with Result task execution condition is set.
Validation rule is selected.
Validation rule execution result is set.
