BonoboMonikerSimple
A super easy to use moniker implementation wrapper
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:
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:
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;
}
