## Casos de Uso { #use-cases }

Alguns casos de uso incluem:

* Converter requisições não-JSON para JSON (por exemplo, <a href="https://msgpack.org/index.html" class="external-link" target="_blank">`msgpack`</a>).
* Descomprimir corpos de requisição comprimidos com gzip.
* Registrar automaticamente todos os corpos de requisição.

      this.array = array;

## First Translation PR

When there's a first translation for a language, it will have a `docs/{lang code}/docs/index.md` translated file and a `docs/{lang code}/mkdocs.yml`.

For example, for Bosnian, it would be:

* `docs/bs/docs/index.md`
* `docs/bs/mkdocs.yml`

The `mkdocs.yml` file will have only the following content:

```YAML
INHERIT: ../en/mkdocs.yml
```

			ID uint
		}
		Level3 struct {
			ID       uint
			Level4ID sql.NullInt64 `sql:"index"`
			Level4   *Level4
		}
		Level2 struct {
			ID      uint
			Level3s []*Level3 `gorm:"many2many:level2_level3s"`
		}
		Level1 struct {
			ID       uint
			Level2ID sql.NullInt64 `sql:"index"`
			Level2   *Level2
		}
	)

   *     uniqueIndex(allColors, c -> c.toString());
   * assertThat(colorForName).containsEntry("red", red);
   * }
   *
   * <p>If your index may associate multiple values with each key, use {@link
   * Multimaps#index(Iterable, Function) Multimaps.index}.
   *
   * <p><b>Note:</b> on Java 8+, it is usually better to use streams. For example:

   * assertThat(colorForName).containsEntry("red", red);
   * }

 * This can help Google index your videos and display them in Google Video search results.
