‘after_load’ in database.load ‘after_backup’ in database.backup ‘before_unload’ in database.unload ‘configuration_defaults’ in configuration.set_defaults ‘before_repetititon’ in SM2_mnemosyne.grade_answer extra argument: card ‘after_repetititon’ in SM2_mnemosyne.grade_answer extra argument: card ‘dynamically_create_media_files’ in SQLite_sync extra argument: data ‘delete_unused_media_files’ in SQLite_sync
It is the ‘run’ method that will get called at the corresponding point in the program.
