"Kotlin" language specificities

Telosys version : 4.1.0

To define Kotlin as the target language call #set( $env.language = 'Kotlin' ) in the templates files.

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

Type conversion ( model type to language type )

The language type conversion has an impact on :

$attribute.type
$attribute.fullType
$attribute.simpleType
$attribute.wrapperType
$attribute.isPrimitiveType()

Model type	Default	@UnsignedType	@NotNull	@PrimitiveType	@ObjectType
string	String?	String?	String	String?	String?
byte	Byte?	UByte?	Byte	Byte?	Byte?
short	Short?	UShort?	Short	Short?	Short?
int	Int?	UInt?	Int	Int?	Int?
long	Long?	ULong?	Long	Long?	Long?
decimal	BigDecimal?	BigDecimal?	BigDecimal	BigDecimal?	BigDecimal?
float	Float?	Float?	Float	Float?	Float?
double	Double?	Double?	Double	Double?	Double?
boolean	Boolean?	Boolean?	Boolean	Boolean?	Boolean?
date	LocalDate?	LocalDate?	LocalDate	LocalDate?	LocalDate?
time	LocalTime?	LocalTime?	LocalTime	LocalTime?	LocalTime?
timestamp	LocalDateTime?	LocalDateTime?	LocalDateTime	LocalDateTime?	LocalDateTime?
binary	ByteArray?	ByteArray?	ByteArray	ByteArray?	ByteArray?

Remarks

'@UnsignedType' :
has effect only for 'byte', 'short', 'int' and 'long'
'@NotNull' :
no effect on types, use '$kotlin' object for 'nullable type' with '?'
'@PrimitiveType' :
no effect
'@ObjectType' :
no effect

Literals for TRUE, FALSE and NULL

TRUE	true
FALSE	false
NULL	null
