Creates a question from a QTI file.
Receives parameters from a QTI parser and creates a valid ILIAS question object
- Parameters:
-
object $item The QTI item object integer $questionpool_id The id of the parent questionpool integer $tst_id The id of the parent test if the question is part of a test object $tst_object A reference to the parent test object integer $question_counter A reference to a question counter to count the questions of an imported question pool array $import_mapping An array containing references to included ILIAS objects public
Reimplemented from assQuestionImport.
