Kotlin

Kotlin is a predefined target language since Telosys version 4.1.0

To define Kotlin as the target language in a template file :

#set( $env.language = 'Kotlin' )

A "?" is automatically added to the end of the type if the attribute is "nullable" (no "@NotNull" annotation). To disable this behavior:

#set( $env.typeWithNullableMark = false )

The information below shows the behavior of the generator when Kotlin is the current target language. For a detailed description of type conversion, see the generated documentation : https://www.telosys.org/doc/latest/languages/language-kotlin.html

Types conversion

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

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

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

Annotations effects

• @UnsignedType has effect only for byte, short, int, long

• @ObjectType no effect

• @NotNull type not nullable => no "?" at the end of the type

• @PrimitiveType no effect

Literal values

TRUE, FALSE, NULL

TRUE	true
FALSE	false
