Name
Registration -- Registering CORBA objects to OAF.
Description
When writing a component which can be activated through
OAF by clients, you need to be register your component
to OAF once it is created.
Details
enum OAF_RegistrationResult
typedef enum
{
OAF_REG_SUCCESS,
OAF_REG_NOT_LISTED,
OAF_REG_ALREADY_ACTIVE,
OAF_REG_ERROR
}
OAF_RegistrationResult; |
oaf_active_server_register ()
Registers obj with iid in the local OAF daemon.
oaf_active_server_unregister ()
void oaf_active_server_unregister (const char *iid,
CORBA_Object obj); |
Unregisters obj with iid in the local OAF daemon.
struct OAFPlugin
typedef struct
{
const OAFPluginObject *plugin_object_list;
const char *description;
}
OAFPlugin; |
Components which want to be activated as
shared libraries must export an OAFPlugin
structure of name OAF_Plugin_info.
An exmaple of how to use it folows:
static CORBA_Object
hi_shlib_make_object (PortableServer_POA poa,
const char *iid,
gpointer impl_ptr,
CORBA_Environment *ev)
{
CORBA_Object object_ref;
object_ref = impl_Hi__create (poa, ev);
if (object_ref == CORBA_OBJECT_NIL
|| ev->_major != CORBA_NO_EXCEPTION) {
printf ("Server cannot get objref\n");
return CORBA_OBJECT_NIL;
}
oaf_plugin_use (poa, impl_ptr);
return object_ref;
}
static const OAFPluginObject hi_plugin_list[] = {
{
"OAFIID:Hi:20000923",
hi_shlib_make_object
},
{
NULL
}
};
const OAFPlugin OAF_Plugin_info = {
hi_plugin_list,
"Hi example"
}; |
struct OAFPluginObject
typedef struct
{
const char *iid;
/* This routine should call oaf_plugin_use(servant, impl_ptr),
* as should all routines which activate CORBA objects
* implemented by this shared library. This needs to be done
* before making any CORBA calls on the object, or
* passing that object around. First thing after servant creation
* always works. :)
*/
CORBA_Object (*activate) (PortableServer_POA poa,
const char *iid,
gpointer impl_ptr, /* This pointer should be stored by the implementation
* to be passed to oaf_plugin_unuse() in the
* implementation's destruction routine. */
CORBA_Environment * ev);
}
OAFPluginObject; |
oaf_plugin_use ()
void oaf_plugin_use (PortableServer_Servant servant,
gpointer impl_ptr); |
You should call this routine to activate a shared library-based
CORBA Object. It will be called by OAF if the component exports
correctly an OAFPlugin structure named "OAF_Plugin_info".
oaf_plugin_unuse ()
void oaf_plugin_unuse (gpointer impl_ptr); |
Side effects: May arrange for the shared library that the
implementation is in to be unloaded.
When a shlib plugin for a CORBA object is destroying an
implementation, it should call this function to make sure that the
shared library is unloaded as needed.
