Golang

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

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

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

Types conversion

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

Model type	Go type	with annotation
string	string
byte	byte uint8	@UnsignedType
short	int16 uint16	@UnsignedType
int	int32 uint32	@UnsignedType
long	int64 uint64	@UnsignedType
decimal	float64
float	float32
double	float64
boolean	bool
date	time.Time
time	time.Time
timetz	time.Time
datetime	time.Time
datetimetz	time.Time
timestamp	time.Time
uuid	uuid.UUID
binary	[ ] byte

Annotations effects

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

• @ObjectType no effect

• @NotNull no effect

• @PrimitiveType no effect

Specific types

• $attribute.fullType no effect (always returns the standard Go type)

• $attribute.simpleType

  no effect (always returns the standard Go type)

• $attribute.wrapperType no effect (always returns the standard Go type)

So, for Golang you can always use the basic "$attribute.type"

Literal values

TRUE, FALSE, NULL

	Golang literal
TRUE	true
FALSE	false
NULL	nil

Generated literal values

Below some examples of literal values generated for each type :

Model type	Golang type	Golang literal value
string	string	"AAA"
byte	byte uint8	1
short	int16 uint16	1
int	int32 uint32	100
long	int64 uint64	1000
decimal	float64	10000.77
float	float32	1000.5
double	float64	1000.66
boolean	bool	true or false
date	time.Time	nil
time	time.Time	nil
timestamp	time.Time	nil
binary	[ ] byte	nil
