public function MigrateExecutable::processRow in Drupal 8

Same name and namespace in other branches

1. 9 core/modules/migrate/src/MigrateExecutable.php \Drupal\migrate\MigrateExecutable::processRow()

Processes a row.

Parameters

\Drupal\migrate\Row $row: The $row to be processed.

array $process: (optional) A process pipeline configuration. If not set, the top level process configuration in the migration entity is used.

mixed $value: (optional) Initial value of the pipeline for the first destination. Usually setting this is not necessary as $process typically starts with a 'get'. This is useful only when the $process contains a single destination and needs to access a value outside of the source. See \Drupal\migrate\Plugin\migrate\process\SubProcess::transformKey for an example.

Throws

\Drupal\migrate\MigrateException
