assClozeTestImport::fromXML ( &  $item,
  $questionpool_id,
&  $tst_id,
&  $tst_object,
&  $question_counter,
&  $import_mapping 
)

Creates a question from a QTI file.

Receives parameters from a QTI parser and creates a valid ILIAS question object

Parameters
object$itemThe QTI item object
integer$questionpool_idThe id of the parent questionpool
integer$tst_idThe id of the parent test if the question is part of a test
object$tst_objectA reference to the parent test object
integer$question_counterA reference to a question counter to count the questions of an imported question pool
array$import_mappingAn array containing references to included ILIAS objects public

Reimplemented from assQuestionImport.
