Member Function Documentation

close_xml_writer()

moodle1_xml_handler::close_xml_writer ( )

protected

Close the XML writer.

At the moment, the caller must close all tags before calling

Return values

void

Reimplemented in moodle1_qtype_handler.

get_converter()

moodle1_handler::get_converter ( )

inherited

Return values

moodle1_converter

the converter that required this handler

has_xml_writer()

moodle1_xml_handler::has_xml_writer ( )

protected

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() )

protected

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

open_xml_writer()

moodle1_xml_handler::open_xml_writer ( $filename )

protected

Opens the XML writer - after calling, one is free to use $xmlwriter.

Parameters

string

$filename

XML file name to write into

Return values

void

Reimplemented in moodle1_qtype_handler.

write_xml()

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

protected

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
