Detailed Description

Multianswer (aka embedded, cloze) question type conversion handler.

Member Function Documentation

close_xml_writer()

moodle1_qtype_handler::close_xml_writer ( )

finalprotectedinherited

Question type handlers cannot close the xml_writer.

Reimplemented from moodle1_xml_handler.

get_component_name()

moodle1_plugin_handler::get_component_name ( )

inherited

Returns the normalized name of the plugin, eg mod_workshop.

Return values

string

get_converter()

moodle1_handler::get_converter ( )

inherited

Return values

moodle1_converter

the converter that required this handler

get_default_numerical_options()

moodle1_qtype_handler::get_default_numerical_options ( $oldquestiontextformat, $units )

protectedinherited

Returns default numerical_option structure.

This structure is not present in moodle.xml, we create a new artificial one here.

See also

write_numerical_options()

Parameters

int

$oldquestiontextformat

Return values

array

get_paths()

moodle1_qtype_handler::get_paths ( )

finalinherited

See also

self\get_question_subpaths()

get_question_subpaths()

moodle1_qtype_multianswer_handler::get_question_subpaths

(

)

Return values

array

Reimplemented from moodle1_qtype_handler.

has_xml_writer()

moodle1_xml_handler::has_xml_writer ( )

protectedinherited

Checks if the XML writer has been opened by self::open_xml_writer().

Return values

bool

log()

moodle1_handler::log ( $message, $level, $a = null, $depth = null, $display = false )

inherited

This function will be responsible for handling the params, and to call to the corresponding logger->process() once all modifications in params have been performed.

Implements loggable.

make_sure_xml_exists()

moodle1_xml_handler::make_sure_xml_exists ( $filename, $rootelement = false, $content = array() )

protectedinherited

Makes sure that a new XML file exists, or creates it itself.

This is here so we can check that all XML files that the restore process relies on have been created by an executed handler. If the file is not found, this method can create it using the given $rootelement as an empty root container in the file.

Parameters

string	$filename	relative file name like 'course/course.xml'
string | bool	$rootelement	root element to use, false to not create the file
array	$content	content of the root element

Return values

bool	true is the file existed, false if it did not

migrate_files()

moodle1_qtype_handler::migrate_files ( $text, $component, $filearea, $itemid )

protectedinherited

Migrate files belonging to one qtype plugin text field.

Parameters

array	$text	the html fragment containing references to files
string	$component	the component for restored files
string	$filearea	the file area for restored files
int	$itemid	the itemid for restored files

Return values

string

the text for this field, after files references have been processed

open_xml_writer()

moodle1_qtype_handler::open_xml_writer ( $filename )

finalprotectedinherited

Question type handlers cannot open the xml_writer.

Reimplemented from moodle1_xml_handler.

process_question()

moodle1_qtype_multianswer_handler::process_question	(	array	$data,
		array	$raw )

Appends the multianswer specific information to the question.

Note that there is an upgrade step 2008050800 that is not replayed here as I suppose there was an error on restore and the backup file contains correct data. If I'm wrong on this assumption then the parent of the embedded questions could be fixed on conversion in theory (by using a temporary stash that keeps multianswer's id and its sequence) but the category fix would be tricky in XML.

Reimplemented from moodle1_qtype_handler.

use_xml_writer()

moodle1_qtype_handler::use_xml_writer ( xml_writer $xmlwriter )

inherited

Provides a xml_writer instance to this qtype converter.

Parameters

xml_writer

$xmlwriter

write_answers()

moodle1_qtype_handler::write_answers ( array $answers, $qtype )

protectedinherited

Converts the answers and writes them into the questions.xml.

The structure "answers" is used by several qtypes. It contains data from {question_answers} table.

Parameters

array	$answers	as parsed by the grouped parser in moodle.xml
string	$qtype	containing the answers

write_dataset_definitions()

moodle1_qtype_handler::write_dataset_definitions ( array $datasetdefinitions )

protectedinherited

Writes the dataset_definitions structure.

Parameters

array

$datasetdefinitions

array of dataset_definition structures

write_numerical_options()

moodle1_qtype_handler::write_numerical_options ( array $numericaloption )

protectedinherited

Writes the numerical_options structure.

See also

get_default_numerical_options()

Parameters

array

$numericaloption

write_numerical_units()

moodle1_qtype_handler::write_numerical_units ( array $numericalunits )

protectedinherited

Writes the grouped numerical_units structure.

Parameters

array

$numericalunits

write_xml()

moodle1_xml_handler::write_xml ( $element, array $data, array $attribs = array(), $parent = '/' )

protectedinherited

Writes the given XML tree data into the currently opened file.

Parameters

string	$element	the name of the root element of the tree
array	$data	the associative array of data to write
array	$attribs	list of additional fields written as attributes instead of nested elements
string	$parent	used internally during the recursion, do not set yourself
