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.

destroy()

base_step::destroy ( )

inherited

Destroy all circular references.
