Java
Java is the target language by default, so you don't have to define it explicitly.
However, you can define it with the following instruction :
#set( $env.language = 'Java' )
The information below shows the behavior of the generator when Java is the current target language. For a detailed description of type conversion, see the generated documentation :
https://www.telosys.org/doc/latest/languages/language-java.html
The table below describes how model neutral types are automatically converted to Java types with potential impact due to attribute annotations.
Model type | Java type | with annotation |
|---|---|---|
string | String | |
byte | Byte
byte
byte | @NotNull
@PrimitiveType |
short | Short short short | @NotNull
@PrimitiveType |
int | Integer
int int | @NotNull
@PrimitiveType |
long | Long long long | @NotNull
@PrimitiveType |
decimal | BigDecimal | |
float | Float float float | @NotNull
@PrimitiveType |
double | Double double double | @NotNull
@PrimitiveType |
boolean | Boolean boolean boolean | @NotNull
@PrimitiveType |
date | LocalDate (since v 4.0)
Date (before v 4.0) | |
time | LocalTime (since v 4.0)
Date (before v 4.0) | |
timestamp | LocalDateTime (since v 4.0)
Date (before v 4.0) | |
binary | byte [ ] | |
- @UnsignedType no effect (all numeric types are signed in Java)
- @ObjectType switches to the standard wrapper type for the current type (Byte, Short, Integer, Long, Float, Double, Boolean)
- @PrimitiveType switches to the primitive type if possible (byte, short, int, long, float, double, boolean)
- @NotNull switches to primitive type if possible in order to avoid 'null' value
- $attribute.fullType
- for an "object type" returns the fully-qualified class name (java.lang.String, java.lang.Integer, java.math.BigDecimal, etc )
- for a "primitive type" returns the primitive type as is( int, double, etc )
- $attribute.simpleType
- for an "object type" returns the simple class name ( String, Integer, Double, etc )
- for a "primitive type" returns the primitive type as is( int, double, etc )
- $attribute.wrapperType returns the Java wrapper type class associtated with the current type (Integer, Double, etc )
