bonobo-storage — Abstract implementation of the Bonobo::Storage interface

Synopsis




void                bonobo_storage_copy_to              (Bonobo_Storage src,
                                                         Bonobo_Storage dest,
                                                         CORBA_Environment *ev);

Description

The BonoboStorage C interface is extremely simple, this is since the CORBA client interface is where the action occurs. It is anticipated that relatively few people need to implement the Bonobo/Storage IDL interface.

The common entry point for BonoboStorage is that of opening a storage using the bonobo_storage_open function, perhaps by a container to use to persist a compound document:

Example 23. An example storage use case

void
container_save (SampleApp         *app,
                const char        *filename,
                CORBA_Environment *ev)
{
	BonoboStorage *storage;
	Bonobo_Storage corba_storage;
	GList *components;
	int i;

	storage = bonobo_storage_open (STORAGE_TYPE, filename,
				       Bonobo_Storage_READ |
				       Bonobo_Storage_WRITE |
				       Bonobo_Storage_CREATE,
				       0664);
	g_return_if_fail (storage);

	corba_storage = BONOBO_OBJREF (storage);

	... 
	Serialize components to streams created in the storage
	...

	Bonobo_Storage_commit (corba_storage, ev);

	CORBA_exception_free (ev);

	bonobo_object_unref (BONOBO_OBJECT (storage));
}

bonobo_storage_copy_to ()

void                bonobo_storage_copy_to              (Bonobo_Storage src,
                                                         Bonobo_Storage dest,
                                                         CORBA_Environment *ev);

Implements a pure CORBA method for copying one storage into another, this is used by several BonoboStorage implemetations where a fast case localy copy cannot work.

src : the source storage
dest : the destination storage
ev : CORBA exception environment
