It is not an abstract method for backward compatibility reasons.

Parameters

backup_nested_element $customfieldelement The custom field element to be backed up.

Reimplemented in customfield_textarea\data_controller.

◆ create()

static core_customfield\data_controller::create	(	int	$id,
		?\stdClass	$record = null,
		?field_controller	$field = null )

staticinherited

Creates an instance of data_controller.

Parameters $id, $record and $field can complement each other but not conflict. If $id is not specified, fieldid must be present either in $record or in $field. If $id is not specified, instanceid must be present in $record

No DB queries are performed if both $record and $field are specified.

Parameters

int	$id
stdClass \| null	$record
field_controller \| null	$field

Return values

data_controller

Exceptions
