Native C++ exceptions portability macros.

The following macros are used to write code portable between platforms with and without native C++ exception support. Their main goal is to hide the presence of the ACE_ENV_TYPE argument, but they collaborate with the ACE_TRY_* macros to emulate the try/catch blocks.

#define ACE_ENV_EMIT_CODE(X)   X
 Define a macro to emit code only when ACE_ENV_TYPE is used.
#define ACE_ENV_EMIT_CODE2(X, Y)   X,Y
 Another macro to emit code only when ACE_ENV_TYPE is used.
#define ACE_ENV_EMIT_DUMMY
 Helper macro.

#define ACE_ENV_SINGLE_ARG_DECL_WITH_DEFAULTS
#define ACE_ENV_SINGLE_ARG_DECL_NOT_USED   ACE_ENV_EMIT_CODE(ACE_ENV_TYPE &)
 Declare a ACE_ENV_TYPE argument for methods which don't use it.
#define ACE_ENV_ARG_PARAMETER

Detailed Description

Id:
CORBA_macros.h 80826 2008-03-04 14:51:23Z wotte

Writing code that is portable between platforms with or without native C++ exceptions is hard. The following macros offer some help on this task, mostly oriented to making the ORB code and the IDL generated code portable.

Value:
ACE_ENV_EMIT_CODE2(ACE_ENV_EMIT_DUMMY, \
                       ACE_ENV_TYPE &ACE_TRY_ENV)

Declare a ACE_ENV_TYPE argument as the last argument of a function Normally this macro is used as follows:

void my_funct (int x, int y ACE_ENV_ARG_DECL);

Its purpose is to provide developers (and users) with a mechanism to write code that is portable to platforms with and without native C++ exceptions.

Definition at line 493 of file CORBA_macros.h.

#define ACE_ENV_ARG_DECL_NOT_USED
Value:
ACE_ENV_EMIT_CODE2(ACE_ENV_EMIT_DUMMY, \
                       ACE_ENV_TYPE &)

Declare a ACE_ENV_TYPE argument that is not used by the function definition. Similar to ACE_ENV_ARG_DECL, but the formal parameter name is dropped to avoid warnings about unused parameters

Definition at line 515 of file CORBA_macros.h.

#define ACE_ENV_ARG_DECL_WITH_DEFAULTS
Value:
ACE_ENV_EMIT_CODE2(ACE_ENV_EMIT_DUMMY, \

                           ACE_DEFAULT_GET_ENV_METHOD ())

Declare a ACE_ENV_TYPE argument with the default value obtained from the ORB/application. It is similar to ACE_ENV_ARG_DECL. The name of the default environment getter method needs to be changed when switching ORBs or when used with another application.

Definition at line 504 of file CORBA_macros.h.

#define ACE_ENV_ARG_NOT_USED   ACE_ENV_EMIT_CODE(ACE_UNUSED_ARG(ACE_TRY_ENV))

Value:

                          ACE_DEFAULT_GET_ENV_METHOD ())

Declare a ACE_ENV_TYPE argument with a default value for methods that do not take any other parameters. The name of the default environment getter method needs to be changed when switching ORBs or when used in another application.

Definition at line 528 of file CORBA_macros.h.

#define ACE_ENV_SINGLE_ARG_PARAMETER   ACE_ENV_EMIT_CODE(ACE_TRY_ENV)
