# Scala

**Scala** is supported since **version 3.3.0**

To define **Scala** as the **target language** in a template file :

```
#set( $env.language = 'Scala' )
```

The information below shows the behavior of the generator when Scala is the current target language.

For a detailed description of type conversion and literal values see the generated documentation: \

## Types conversion&#x20;

The table below describes how model neutral types are automatically converted to Scala types with potential impact due to attribute annotations.

| Model type    | Scala type         |   |
| ------------- | ------------------ | - |
| string        | **String**         |   |
| byte          | **Byte**           |   |
| short         | **Short**          |   |
| int           | **Int**            |   |
| long          | **Long**           |   |
| decimal       | **BigDecimal**     |   |
| float         | **Float**          |   |
| double        | **Double**         |   |
| boolean       | **Boolean**        |   |
| date          | **LocalDate**      |   |
| time          | **LocalTime**      |   |
| timetz        | **OffsetTime**     |   |
| datetime      | **LocalDateTime**  |   |
| datetimetz    | **OffsetDateTime** |   |
| ~~timestamp~~ | **LocalDateTime**  |   |
| uuid          | **UUID**           |   |
| binary        | **Array\[Byte]**   |   |

### Annotations effects

* **@UnsignedType** : no effect
* **@ObjectType** : no effect
* **@NotNull** : no effect
* **@PrimitiveType**  : no effect

## Literal values

#### TRUE, FALSE, NULL

|       | Scala literal |
| ----- | ------------- |
| TRUE  | **true**      |
| FALSE | **false**     |
| NULL  | **null**      |
