Implementation of DrupalNodeMigration for Drupal 7 sources.

Class

DrupalNode7Migration

Handling specific to a Drupal 7 source for nodes.

Code

public function prepareRow($row) {
  if (parent::prepareRow($row) === FALSE) {
    return FALSE;
  }

  // The property 'tnid' cannot be handled via sourceMigration() method
  // because it might be 0 or the main node of translation set. We don't want
  // to create a stub for such cases.

      ->getMap()
      ->lookupDestinationID(array(
      $row->tnid,

        // updatable stubs.
