C++ mappings for predefined IDL datatypes

Table 7-1 lists the CORBA IDL types predefined in EAServer and the equivalent C++ datatypes. You can also define additional types in IDL; when you generate stubs and skeletons, these are translated to C++ types using the standard CORBA IDL to C++ type mappings. For example, The BCD and MJD CORBA IDL modules define types to represent binary data, fixed-point numeric data, dates, and times. For details, see the generated Interface Repository documentation for these IDL modules.

**Table 7-1: C++ datatype mappings for predefined CORBA IDL types**
CORBA IDL type	Argument mode	IDL C++ type
short	in inout out return	CORBA::Short CORBA::Short& CORBA::Short_out CORBA::Short
long	in inout out return	CORBA::Long CORBA::Long& CORBA::Long_out CORBA::Long
long long	in inout out return	CORBA::LongLong CORBA::LongLong& CORBA::LongLong_out CORBA::LongLong Define JAG_LONGLONG Because there is no standard C++ type for an signed 64-bit integer, you must define the JAG_LONGLONG macro as your compiler’s type for a signed 64-bit integer.
float	in inout out return	CORBA::Float CORBA::Float& CORBA::Float_out CORBA::Float
double	in inout out return	CORBA::Double CORBA::Double& CORBA::Double_out CORBA::Double
boolean	in inout out return	CORBA::Boolean CORBA::Boolean& CORBA::Boolean_out CORBA::Boolean
string	in inout out return	char* char& CORBA::String_out char
BCD::Binary	in inout out return	BCD::Binary& BCD::Binary& BCD::Binary_out BCD::Binary*
BCD::Decimal	in inout out return	BCD::Decimal& BCD::Decimal& BCD::Decimal_out BCD::Decimal*
