"Java" language specificities

Telosys version : 4.1.0

Java is the default target language
therefore it is not necessary to call '#set( $env.language = 'Java' )' in the templates files.

The information below shows the behavior of the generator when 'Java' 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	Byte	byte	byte	Byte
short	Short	Short	short	short	Short
int	Integer	Integer	int	int	Integer
long	Long	Long	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	byte[]	byte[]	byte[]	byte[]	byte[]

Remarks

'@UnsignedType' :
has no effect (all numeric types are signed in Java)
'@NotNull' :
switches to primitive type if possible (in order to avoid 'null' value)
'@PrimitiveType' :
switches to primitive type if possible (short, int, boolean, etc)
'@ObjectType' :
switches primitive types to standard wrapper types (Short, Integer, Long, Float, etc)

Literals for TRUE, FALSE and NULL

TRUE	true
FALSE	false
NULL	null
