Description

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;
}
