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_converterthe 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_calculated_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$filenamerelative file name like 'course/course.xml'
string | bool$rootelementroot element to use, false to not create the file
array$contentcontent of the root element
Return values
booltrue 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$textthe html fragment containing references to files
string$componentthe component for restored files
string$fileareathe file area for restored files
int$itemidthe itemid for restored files
Return values
stringthe 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_calculated_handler::process_question ( array $data,
array $raw )

Provides a xml_writer instance to this qtype converter.

Parameters
xml_writer$xmlwriter

◆ write_answers()

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

string$qtypecontaining the answers

◆ write_dataset_definitions()

moodle1_qtype_handler::write_dataset_definitions ( array $datasetdefinitions)
protectedinherited
