BonoboMonikerSimple makes writing monikers really extremely easy. To implement a moniker you only have to write 1 function. To register create the moniker object you have to use only 1 call. It can't get much simpler. If you want to use monikers instead of implementing them, you probably want to see bonobo-moniker-util instead.
Few people need to implement monikers, but if they do, this is how they should do it:
Example 1. A cut down file: moniker implementation
Bonobo_Unknown bonobo_moniker_file_resolve (BonoboMoniker *moniker, const Bonobo_ResolveOptions *options, const CORBA_char *requested_interface, CORBA_Environment *ev) { const char *fname = bonobo_moniker_get_name (moniker); Bonobo_Unknown retval; g_warning ("Fname 's'", fname); if (!strcmp (requested_interface, "IDL:Bonobo/Stream:1.0")) { BonoboStream *stream; stream = bonobo_stream_open ("fs", fname, Bonobo_Storage_READ, 0664); if (!stream) { g_warning ("Failed to open stream 's'", fname); CORBA_exception_set (ev, CORBA_USER_EXCEPTION, ex_Bonobo_Moniker_InterfaceNotFound, NULL); return CORBA_OBJECT_NIL; } return CORBA_Object_duplicate (BONOBO_OBJREF (stream), ev); } return CORBA_OBJECT_NIL; } |
Example 2. Creating a new simple moniker
static BonoboObject * bonobo_std_moniker_factory (BonoboGenericFactory *this, const char *object_id, void *data) { g_return_val_if_fail (object_id != NULL, NULL); if (!strcmp (object_id, "OAFIID:Bonobo_Moniker_File")) return BONOBO_OBJECT (bonobo_moniker_simple_new ( "file:", bonobo_moniker_file_resolve)); else return NULL; } |
Bonobo_Unknown (*BonoboMonikerSimpleResolveFn) (BonoboMoniker *moniker, const Bonobo_ResolveOptions *options, const CORBA_char *requested_interface, CORBA_Environment *ev); |

BonoboMoniker* bonobo_moniker_simple_new (const char *name, BonoboMonikerSimpleResolveFn resolve_fn); |
Create a new instance of a simplified moniker.
name : | the display name for the moniker |
resolve_fn : | a resolve function for the moniker |
Returns : | the moniker object |
BonoboMoniker* bonobo_moniker_simple_construct (BonoboMonikerSimple *moniker, const char *name, BonoboMonikerSimpleResolveFn resolve_fn); |
Constructs a simple moniker
moniker : | the moniker to construct |
name : | the name of the moniker eg. 'file:' |
resolve_fn : | the function used to resolve the moniker |
Returns : | the constructed moniker or NULL on failure. |
