add_datasets_to_history(datasets, for_output_dataset=None)[source]

Add datasets to the history this context points at.

persist_object(obj)[source]

No-op right now for the sessionless variant of this.

This works currently because either things are added to a target history with add_datasets_to_history or the parent LibraryFolder was added to the export store in persist_target_to_export_store.

flush()[source]

No-op for the sessionless variant of this, no database to flush.

add_output_dataset_association(name, dataset)[source]

No-op, no job context to persist this association for.
