Service Configurator macros

The following macros are used to define helper objects used in ACE's Service Configurator framework, which is described in Chapter 5 of C++NPv2 <www.cs.wustl.edu/~schmidt/ACE/book2/>. This framework implements the Component Configurator pattern, which is described in Chapter 2 of POSA2 <www.cs.wustl.edu/~schmidt/POSA/>. The intent of this pattern is to allow developers to dynamically load and configure services into a system. With a little help from this macros statically linked services can also be dynamically configured.

More details about this component are available in the documentation of the ACE_Service_Configurator class and also ACE_Dynamic_Service.

Notice that in all the macros the SERVICE_CLASS parameter must be the name of a class derived from ACE_Service_Object.

#define ACE_STATIC_SVC_DECLARE(SERVICE_CLASS)   extern ACE_Static_Svc_Descriptor ace_svc_desc_##SERVICE_CLASS ;
#define ACE_STATIC_SVC_DECLARE_EXPORT(EXPORT_NAME, SERVICE_CLASS)   extern EXPORT_NAME##_Export ACE_Static_Svc_Descriptor ace_svc_desc_##SERVICE_CLASS;
#define ACE_STATIC_SVC_DEFINE(SERVICE_CLASS, NAME, TYPE, FN, FLAGS, ACTIVE)   ACE_Static_Svc_Descriptor ace_svc_desc_##SERVICE_CLASS = { NAME, TYPE, FN, FLAGS, ACTIVE };
#define ACE_STATIC_SVC_REQUIRE(SERVICE_CLASS)
 Automatically register a service with the service configurator.

#define ACE_STATIC_SVC_REGISTER(SERVICE_CLASS)   do {} while (0)
#define ACE_FACTORY_DECLARE(CLS, SERVICE_CLASS)
#define ACE_Local_Service_Export
#define ACE_FACTORY_DEFINE(CLS, SERVICE_CLASS)
#define ACE_SVC_NAME(SERVICE_CLASS)   _make_##SERVICE_CLASS
 The canonical name for a service factory method.

#define ACE_SVC_INVOKE(SERVICE_CLASS)   _make_##SERVICE_CLASS (0)

Helper macros for services defined in the netsvcs library.

The ACE services defined in netsvcs use this helper macros for simplicity.

Value:

extern "C" CLS##_Export ACE_Service_Object *\
_make_##SERVICE_CLASS (ACE_Service_Object_Exterminator *);
Once the service implementation is dynamically loaded the Service Configurator uses a factory method to create the object. This macro declares such a factory function with the proper interface and export macros. Normally used in the header file that declares the service implementation.
Parameters:
CLS  must match the prefix of the export macro used for this service.
SERVICE_CLASS  must match the name of the class that implements the service.

#define ACE_FACTORY_DEFINE (  CLS,
SERVICE_CLASS    ) 
 

Value:

void _gobble_##SERVICE_CLASS (void *p) { \
  ACE_Service_Object *_p = ACE_static_cast (ACE_Service_Object *, p); \
  ACE_ASSERT (_p != 0); \
  delete _p; } \
extern "C" CLS##_Export ACE_Service_Object *\
_make_##SERVICE_CLASS (ACE_Service_Object_Exterminator *gobbler) \

  if (gobbler != 0) \
    *gobbler = (ACE_Service_Object_Exterminator) _gobble_##SERVICE_CLASS; \
  return new SERVICE_CLASS; \
}
The macro should be used in the header file where the service is declared, its only argument is usually the name of the class that implements the service.
Parameters:
SERVICE_CLASS  The name of the class implementing the service.

#define ACE_Local_Service_Export
 

Use with arguments matching ACE_FACTORY_DECLARE. Normally used in the .cpp file that defines the service implementation.

This macro defines both the factory method and the function used to cleanup the service object.

If this macro is used to define a factory function that need not be exported (for example, in a static service situation), CLS can be specified as ACE_Local_Service.

#define ACE_STATIC_SVC_DECLARE (  SERVICE_CLASS    )     extern ACE_Static_Svc_Descriptor ace_svc_desc_##SERVICE_CLASS ;
 

The macro should be used in the header file where the service is declared, its only argument is usually the name of the class that implements the service.

Parameters:
SERVICE_CLASS  The name of the class implementing the service.

#define ACE_STATIC_SVC_DECLARE_EXPORT (  EXPORT_NAME,
SERVICE_CLASS    )     extern EXPORT_NAME##_Export ACE_Static_Svc_Descriptor ace_svc_desc_##SERVICE_CLASS;
 

NT compilers require the use of explicit directives to export and import symbols from a DLL. If you need to define a service in a dynamic library you should use this version instead. Normally ACE uses a macro to inject the correct export/import directives on NT. Naturally it also the macro expands to a blank on platforms that do not require such directives. The first argument (EXPORT_NAME) is the prefix for this export macro, the full name is formed by appending _Export. ACE provides tools to generate header files that define the macro correctly on all platforms, please see $ACE_ROOT/bin/generate_export_file.pl

Parameters:
EXPORT_NAME  The export macro name prefix.
SERVICE_CLASS  The name of the class implementing the service.

#define ACE_STATIC_SVC_DEFINE (  SERVICE_CLASS,
NAME,
TYPE,
FN,
FLAGS,
ACTIVE    )     ACE_Static_Svc_Descriptor ace_svc_desc_##SERVICE_CLASS = { NAME, TYPE, FN, FLAGS, ACTIVE };
 

The service configurator requires several arguments to build and control an statically linked service, including its name, the factory function used to construct the service, and some flags. All those parameters are configured in a single structure, an instance of this structure is statically initialized using the following macro.

Parameters:
SERVICE_CLASS  The name of the class that implements the service, must be derived (directly or indirectly) from ACE_Service_Object.
NAME  The name for this service, this name is used by the service configurator to match configuration options provided in the svc.conf file.
TYPE  The type of object. Objects can be streams or service objects. Please read the ACE_Service_Configurator and ASX documentation for more details.
FN  The name of the factory function, usually the ACE_SVC_NAME macro can be used to generate the name. The factory function is often defined using ACE_FACTORY_DECLARE and ACE_FACTORY_DEFINE.
FLAGS  Flags to control the ownership and lifecycle of the object. Please read the ACE_Service_Configurator documentation for more details.
ACTIVE  If not zero then a thread will be dedicate to the service. Please read the ACE_Service_Configurator documentation for more details.

#define ACE_STATIC_SVC_REGISTER (  SERVICE_CLASS    )     do {} while (0)
 

The macro should be used in the header file where the service is declared, its only argument is usually the name of the class that implements the service.

Parameters:
SERVICE_CLASS  The name of the class implementing the service.

#define ACE_STATIC_SVC_REQUIRE (  SERVICE_CLASS    ) 
 

Value:

class ACE_Static_Svc_##SERVICE_CLASS {\
public:\
  ACE_Static_Svc_##SERVICE_CLASS() { \
    ACE_Service_Config::static_svcs ()->insert (\
         &ace_svc_desc_##SERVICE_CLASS); \
    } \
};\
static ACE_Static_Svc_##SERVICE_CLASS ace_static_svc_##SERVICE_CLASS;
Automatically register a service with the service configurator.

In some applications the services must be automatically registered with the service configurator, before main() starts. The ACE_STATIC_SVC_REQUIRE macro defines a class whose constructor register the service, it also defines a static instance of that class to ensure that the service is registered before main.

On platforms that lack adequate support for static C++ objects the macro ACE_STATIC_SVC_REGISTER can be used to explicitly register the service.

Todo:
One class per-Service_Object seems wasteful. It should be possible to define a single class and re-use it for all the service objects, just by passing the Service_Descriptor as an argument to the constructor.
