Detailed Description

Execution step that, conditionally (if there isn't preloaded information will load all the question categories and questions (header info only) to backup_temp_ids.

They will be stored with "question_category" and "question" itemnames and with their original contextid and question category id as paremitemids

Member Function Documentation

apply_date_offset()

restore_step::apply_date_offset ( $value )

inherited

Apply course startdate offset based in original course startdate and course_offset_startdate setting Note we are using one static cache here, but by restoreid, so it's ok for concurrence/multiple executions in the same request.

Note: The policy is to roll date only for configurations and not for user data. see MDL-9367.

Parameters

int

$value

Time value (seconds since epoch), or empty for nothing

Return values

int	Time value after applying the date offset, or empty for nothing

decrypt()

restore_step::decrypt ( $value )

inherited

Returns symmetric-key AES-256 decryption of base64 encoded contents.

This method is used in restore operations to decrypt contents encrypted with encrypted_final_element automatically decoding (base64) and decrypting contents using the key stored in backup_encryptkey config.

Requires openssl, cipher availability, and key existence (backup automatically sets it if missing). Integrity is provided via HMAC.

Parameters

string

$value

encrypted_final_element value to decode and decrypt.

Return values

string|null

decoded and decrypted value or null if the operation can not be performed.

define_execution()

restore_load_categories_and_questions::define_execution ( )

protected

Function that will contain all the code to be executed.

Reimplemented from restore_execution_step.

destroy()

base_step::destroy ( )

inherited

Destroy all circular references.

It helps PHP 5.2 a lot!

execute()

restore_execution_step::execute ( )

inherited

This function will perform all the actions necessary to achieve the execution of the plan/part/task.

Implements executable.

log()

base_step::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.
