Constructor & Destructor Documentation

◆ __construct()

ilCounterDetector::__construct ( ilNode $context )

Default constructor, passing the context to the parent constructor.

Parameters

ilNode $context

Definition at line 41 of file class.ilCounterDetector.php.

         {
                 parent::__construct($context);
         }

Member Function Documentation

◆ getActualTriggerEvents()

ilCounterDetector::getActualTriggerEvents ( )

Returns the actual trigger events of the detector.

Returns: integer Number of past trigger events.

Definition at line 72 of file class.ilCounterDetector.php.

References $actual_trigger_events.

         {
                 return $this->actual_trigger_events;
         }

◆ getExpectedTriggerEvents()

ilCounterDetector::getExpectedTriggerEvents ( )

Returns the currently set number of expected trigger events.

Returns: integer

Definition at line 61 of file class.ilCounterDetector.php.

References $expected_trigger_events.

         {
                 return $this->expected_trigger_events;
         }

◆ setActualTriggerEvents()

ilCounterDetector::setActualTriggerEvents ( $count )

Sets the actual count of trigger events already taken place.

Reason this method exists, is to allow the workflow controller to "fast forward" workflows to set a non-default state. I.e. a workflow has to be set into a state in the middle of running. Use with care.

Parameters

integer $count Number of past trigger events.

Definition at line 87 of file class.ilCounterDetector.php.

                 if ($this->expected_trigger_events < (int) $count)

                 else 
                 {
                         // TODO: throw actual must be smaller than expected.
                 }
         }

◆ setExpectedTriggerEvents()

ilCounterDetector::setExpectedTriggerEvents ( $count )

Set the expected trigger event count before the detector is satisfied.

Parameters

integer $count

Definition at line 51 of file class.ilCounterDetector.php.

         {
                 $this->expected_trigger_events = (int) $count;
         }

◆ trigger()

ilCounterDetector::trigger ( $params )

Trigger this detector.

Params are an array. These are part of the interface but ignored here.

Todo:: Handle ignored $a_params.

Parameters

array $params

Returns: boolean False, if detector was already satisfied before.

Implements ilDetector.
