TODO: Finish phpdocs

Constructor & Destructor Documentation

__construct()

restore_task::__construct	(		$name,
			$plan = null
	)

Constructor - instantiates one object of this class.

Reimplemented from base_task.

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()

base_task::build ( )

abstractinherited

Function responsible for building the steps of any task (must set the $built property to true)

Reimplemented in backup_activity_task, backup_block_task, backup_course_task, backup_final_task, backup_root_task, backup_section_task, restore_activity_task, restore_block_task, restore_course_task, restore_final_task, restore_root_task, and restore_section_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_settings()

base_task::define_settings ( )

abstractprotectedinherited

This function is invoked on activity creation in order to add all the settings that are associated with one task.

The function will, directly, inject the settings in the task.

Reimplemented in backup_activity_task, backup_block_task, backup_course_task, backup_final_task, backup_root_task, backup_section_task, restore_activity_task, restore_block_task, restore_course_task, restore_final_task, restore_root_task, and restore_section_task.

destroy()

base_task::destroy ( )

inherited

Destroy all circular references.

It helps PHP 5.2 a lot!

execute()

base_task::execute ( )

inherited

Function responsible for executing the steps of any task (setting the $executed property to true)

Implements executable.

Reimplemented in backup_activity_task, backup_section_task, restore_activity_task, and restore_section_task.

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_setting()

base_task::get_setting (   $name )

inherited

Reimplemented in backup_activity_task, backup_section_task, restore_activity_task, and restore_section_task.

get_taskbasepath()

base_task::get_taskbasepath ( )

inherited

Reimplemented in backup_activity_task, backup_block_task, backup_course_task, backup_section_task, restore_activity_task, restore_block_task, restore_course_task, and restore_section_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.
