Here is the call graph for this function:

delete_files	(	$	questionid,
		$	contextid
	)		`[protected]`

Delete all the files belonging to this question.

Parameters:

int	$questionid	the question being deleted.
int	$contextid	the context the question is in.

Reimplemented from qtype_calculated.

Definition at line 288 of file questiontype.php.

Here is the call graph for this function:

get_possible_responses ( $ questiondata )

This method should return all the possible types of response that are recognised for this question.

The question is modelled as comprising one or more subparts. For each subpart, there are one or more classes that that students response might fall into, each of those classes earning a certain score.

For example, in a shortanswer question, there is only one subpart, the text entry field. The response the student gave will be classified according to which of the possible $question->options->answers it matches.

For the matching question type, there will be one subpart for each question stem, and for each stem, each of the possible choices is a class of student's response.

A response is an object with two fields, ->responseclass is a string presentation of that response, and ->fraction, the credit for a response in that class.

Array keys have no specific meaning, but must be unique, and must be the same if this function is called repeatedly.

Parameters:

object $question the question definition data.

Returns:: array keys are subquestionid, values are arrays of possible responses to that subquestion.

make_question_instance ( $ questiondata ) [protected]

Create an appropriate question_definition for the question of this type using data loaded from the database.

Parameters:

object $questiondata the question data loaded from the database.

Returns:: question_definition an instance of the appropriate question_definition subclass. Still needs to be initialised.
