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
