Member Function Documentation

add_result()

base_task::add_result ( $result )

inherited

Add the given info to the current plan's results.

See also

base_plan\add_result()

Parameters

array

$result

associative array describing a result of a task/step

build()

backup_activity_task::build ( )

inherited

Create all the steps that will be part of this task.

Reimplemented from base_task.

calculate_checksum()

base_task::calculate_checksum ( )

inherited

This function will return one unique and stable checksum for one instance of the class implementing it.

It's each implementation responsibility to do it recursively if needed and use optional store (caching) of the checksum if necessary/possible

Implements checksumable.

define_my_settings()

backup_chat_activity_task::define_my_settings ( )

protected

No specific settings for this activity.

Reimplemented from backup_activity_task.

define_my_steps()

backup_chat_activity_task::define_my_steps ( )

protected

Defines a backup step to store the instance data in the chat.xml file.

Reimplemented from backup_activity_task.

define_settings()

backup_activity_task::define_settings ( )

protectedinherited

Defines the common setting that any backup activity will have.

Reimplemented from base_task.

destroy()

base_task::destroy ( )

inherited

Destroy all circular references.

It helps PHP 5.2 a lot!

encode_content_links()

static backup_chat_activity_task::encode_content_links ( $content )

static

Encodes URLs to the index.php and view.php scripts.

Parameters

string

$content

some HTML text that eventually contains URLs to the activity instance scripts

Return values

string

the content with the URLs encoded

Reimplemented from backup_activity_task.

execute()

backup_activity_task::execute ( )

inherited

Exceptionally override the execute method, so, based in the activity_included setting, we are able to skip the execution of one task completely.

Reimplemented from base_task.

get_activityid()

backup_activity_task::get_activityid ( )

inherited

Return values

int	the id of the activity instance (id in the activity's instances table)

get_contextid()

backup_activity_task::get_contextid ( )

inherited

Return values

int	the id of the associated CONTEXT_MODULE instance

get_kept_roles()

backup_task::get_kept_roles ( )

inherited

Get the user roles that should be kept in the destination course for a course copy operation.

Return values

array

get_moduleid()

backup_activity_task::get_moduleid ( )

inherited

Return values

int	the course module id (id in the course_modules table)

get_modulename()

backup_activity_task::get_modulename ( )

inherited

Return values

string

the name of the module, eg 'workshop' (from the modules table)

get_progress()

base_task::get_progress ( )

inherited

Gets the progress reporter, which can be used to report progress within the backup or restore process.

Return values

core\progress\base

Progress reporting object

get_results()

base_task::get_results ( )

inherited

Return the current plan's results.

Return values

array|null

get_sectionid()

backup_activity_task::get_sectionid ( )

inherited

Return values

int	the course section id (id in the course_sections table)

get_setting()

backup_activity_task::get_setting ( $name )

inherited

Tries to look for the instance specific setting value, task specific setting value or the common plan setting value - in that order.

Parameters

string

$name

the name of the setting

Return values

mixed|null

the value of the setting or null if not found

Reimplemented from base_task.

get_taskbasepath()

backup_activity_task::get_taskbasepath ( )

inherited

Return values

string

full path to the directory where this task writes its files

Reimplemented from base_task.

get_weight()

base_task::get_weight ( )

inherited

Returns the weight of this task, an approximation of the amount of time it will take.

By default this value is 1. It can be increased for longer tasks.

Return values

int

Weight

Reimplemented in backup_final_task.

is_checksum_correct()

base_task::is_checksum_correct ( $checksum )

inherited

Given one checksum, returns if matches object's checksum (true) or no (false)

Implements checksumable.

log()

base_task::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.
