C++

C++ language is supported since version 3.3.0

To define C++ as the target language in a template file :

#set( $env.language = 'C++' )

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

Types conversion

The table below describes how model neutral types are automatically converted to C++ types with potential impact due to annotations (@UnsignedType, @NotNull, @PrimitiveType, @ObjectType)

Model type	C++ type	with annotation
string	std::string
byte	char unsigned char	@UnsignedType
short	short unsigned short	@UnsignedType
int	int unsigned int	@UnsignedType
long	long unsigned long	@UnsignedType
decimal	double
float	float
double	double
boolean	bool
date	std::chrono::year_month_day
time	std::chrono::hh_mm_ss
timetz	std::chrono::hh_mm_ss
datetime	std::chrono::local_time
datetimetz	std::chrono::zoned_time
timestamp	std::chrono::local_time
uuid	std::string
binary	std::vector

Annotations effects

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

• @NotNull has no effect

• @PrimitiveType no effect

• @ObjectType no effect

Specific types

• $attribute.fullType no effect

• $attribute.simpleType no effect

• $attribute.wrapperType no effect

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

Literal values

TRUE, FALSE, NULL

	C++ literal
TRUE	true
FALSE	false
NULL	NULL

Generated literal values

Below some examples of literal values generated for each type :

Model type	C++ type	C++ literal value
string	string	"AAA"
byte	char unsigned char	1
short	short unsigned short	1
int	int unsigned int	100
long	long unsigned long	1000
decimal	double	10000.77
float	float	1000.5
double	double	1000.66
boolean	bool	true or false
date	std::tm	NULL
time		NULL
timestamp		NULL
binary		NULL
