Constructor & Destructor Documentation

◆ __construct()

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

Constructor - instantiates one object of this class.

Reimplemented in backup_task, and restore_task.

Member Function Documentation

◆ add_result()

base_task::add_result (   $result)

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

See also
base_plan::add_result()
Parameters
array$resultassociative array describing a result of a task/step

◆ build()

base_task::build ( )
abstract

◆ calculate_checksum()

base_task::calculate_checksum ( )

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 ( )
abstractprotected

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 ( )

Destroy all circular references.

It helps PHP 5.2 a lot!

◆ execute()

base_task::execute ( )

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 ( )

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

Return values
core::progress::baseProgress reporting object

◆ get_results()

base_task::get_results ( )

Return the current plan's results.

Return values
array|null

◆ get_setting()

base_task::get_setting (   $name)

◆ get_taskbasepath()

base_task::get_taskbasepath ( )

◆ get_weight()

base_task::get_weight ( )

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
intWeight

Reimplemented in backup_final_task.

◆ is_checksum_correct()

base_task::is_checksum_correct (   $checksum)

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 
)

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.
