## Adicionar a tarefa em segundo plano

Dentro de sua _função de operação de caminho_, passe sua função de tarefa para o objeto _tarefas em segundo plano_ com o método `.add_task()`:

```Python hl_lines="14"
{!../../docs_src/background_tasks/tutorial001.py!}
```

`.add_task()` recebe como argumentos:

- Uma função de tarefa a ser executada em segundo plano (`write_notification`).

        PatternSet source = new PatternSet();
        source.setExcludes( Arrays.asList( "first", "second", "third" ) );

        modelMerger.mergePatternSet_Excludes( target, source, true, null );

        assertThat( target.getExcludes(), contains( "first", "second", "third" ) );
    }
