public function MediaFileCopy::transform in Migrate File Entities to Media Entities 8

Performs the associated process.

Parameters

mixed $value: The value to be transformed.

\Drupal\migrate\MigrateExecutableInterface $migrate_executable: The migration in which this process is being executed.

\Drupal\migrate\Row $row: The row from the source to process. Normally, just transforming the value is adequate but very rarely you might need to change two columns at the same time or something like that.

string $destination_property: The destination property currently worked on. This is only used together with the $row above.

Return value

string|array The newly transformed value.
