BonoboMonikerSimple — A super easy to use moniker implementation wrapper
struct BonoboMonikerSimple; struct BonoboMonikerSimpleClass; Bonobo_Unknown (*BonoboMonikerSimpleResolveFn) (BonoboMoniker *moniker, const Bonobo_ResolveOptions *options, const CORBA_char *requested_interface, CORBA_Environment *ev); BonoboMoniker* bonobo_moniker_simple_construct (BonoboMonikerSimple *moniker, const char *name, GClosure *resolve_closure); BonoboMoniker* bonobo_moniker_simple_new (const char *name, BonoboMonikerSimpleResolveFn resolve_fn); BonoboMoniker* bonobo_moniker_simple_new_closure (const char *name, GClosure *resolve_closure);
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; }
After implementing the resolve function, you need to create the new moniker in your standard factory:
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; }
struct BonoboMonikerSimpleClass { BonoboMonikerClass parent_class; };
BonoboMonikerSimple's class.
Bonobo_Unknown (*BonoboMonikerSimpleResolveFn) (BonoboMoniker *moniker, const Bonobo_ResolveOptions *options, const CORBA_char *requested_interface, CORBA_Environment *ev);
Type of callback function that implements a simple moniker resolution.
moniker : | the moniker |
options : | resolve options |
requested_interface : | the requested interface (repoid string) |
ev : | CORBA environment, in case an exception needs to be raised |
Returns : | a Bonobo_Unknown as the result of the resolution |
BonoboMoniker* bonobo_moniker_simple_construct (BonoboMonikerSimple *moniker, const char *name, GClosure *resolve_closure);
Constructs a simple moniker
moniker : | the moniker to construct |
name : | the name of the moniker eg. 'file:' |
resolve_closure : | the closure used to resolve the moniker |
Returns : | the constructed moniker or NULL on failure. |
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_new_closure (const char *name, GClosure *resolve_closure);
Create a new instance of a simplified moniker.
Instead of the Bonobo_ResolveOptions struct, the closure takes its contents as two arguments: BONOBO_TYPE_RESOLVE_FLAG and G_TYPE_LONG.
name : | the display name for the moniker |
resolve_closure : | a closure for the resolve process. |
Returns : | the moniker object |
