Details
__construct(MigrationInterface $migration, MigrateMessageInterface $message, OutputInterface $output, array $options = [])
Constructs a new migrate executable instance.
void
onMapSave(MigrateMapSaveEvent $event)
Counts up any map save events.
void
onMapDelete(MigrateMapDeleteEvent $event)
Counts up any rollback events.
void
onPreImport(MigrateImportEvent $event)
Reacts when the import is about to start.
protected void
handleMissingSourceRows(MigrationInterface $migration)
Handles missing source rows after import.
Detect if, before importing, the destination contains rows that are no
more available in the source. If we can build such a list, we dispatch
the \Drush\Drupal\Migrate\MigrateMissingSourceRowsEvent event, allowing
subscribers to perform specific actions on detected destination objects.
We also provide a default listener to this event that rolls-back the
items, if the --delete option has been passed.
Custom subscribers, provided by third-party code, may also subscribe,
with a higher priority, to the same event, and perform different tasks,
such as unpublishing the destination entity and then stopping the event
propagation, thus avoiding the destination object rollback, even when
the--delete option has been passed.
void
onMissingSourceRows(MigrateMissingSourceRowsEvent $event)
Reacts on detecting a list of missing source rows after an import.
Note that third-party code may subscribe to the same event, with a higher
priority, and perform different tasks, such as unpublishing the
destination entity and then stopping the event propagation, thus avoiding
the destination object deletion, even the --delete option was passed.
void
onPostImport(MigrateImportEvent $event)
Reacts to migration completion.
protected void
importFeedbackMessage(bool $done = true)
Emits information on the import progress.
void
onPreRollback(MigrateRollbackEvent $event)
Reacts when the rollback is about to starts.
void
onPostRollback(MigrateRollbackEvent $event)
Reacts to rollback completion.
protected void
rollbackFeedbackMessage(bool $done = true)
Emits information on the rollback execution progress.
void
onPreRowSave(MigratePreRowSaveEvent $event)
Reacts to an item about to be imported.
void
onPostRowSave(MigratePostRowSaveEvent $event)
Reacts aftre a row has been deleted.
void
onPostRowDelete(MigrateRowDeleteEvent $event)
Reacts to item rollback.
void
onPrepareRow(MigratePrepareRowEvent $event)
Reacts to a new row being prepared.
