Detailed Description

Abstract class defining the basis for one execution (backup/restore) plan.

Member Function Documentation

add_result()

base_plan::add_result

(

$result

)

Add the passed info to the plan results.

At the moment we expect an associative array structure to be merged into the current results. In the future, some sort of base_result class may be introduced.

Parameters

array

$result

associative array describing a result of a task/step

calculate_checksum()

base_plan::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.

destroy()

base_plan::destroy

(

)

Destroy all circular references.

It helps PHP 5.2 a lot!

Reimplemented in restore_plan, and backup_plan.

get_progress()

base_plan::get_progress ( )

abstract

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

Return values

core

Reimplemented in restore_plan, and backup_plan.

get_results()

base_plan::get_results

(

)

Return the results collected via self::add_result() method.

Return values

array

get_setting()

base_plan::get_setting

(

$name

)

return one setting by name, useful to request root/course settings that are, by definition, unique by name.

Parameters

string

$name

name of the setting

Return values

base_setting

Exceptions

base_plan_exception

if setting name is not found.
