matecomponent-storage — Abstract implementation of the MateComponent::Storage interface

Synopsis

void                matecomponent_storage_copy_to       (MateComponent_Storage src,
                                                         MateComponent_Storage dest,
                                                         CORBA_Environment *ev);

Description

The MateComponentStorage 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 MateComponent/Storage IDL interface.

The common entry point for MateComponentStorage is that of opening a storage using the matecomponent_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)
{
	MateComponentStorage *storage;
	MateComponent_Storage corba_storage;
	GList *components;
	int i;
	storage = matecomponent_storage_open (STORAGE_TYPE, filename,
				       MateComponent_Storage_READ |
				       MateComponent_Storage_WRITE |
				       MateComponent_Storage_CREATE,
				       0664);
	g_return_if_fail (storage);
	corba_storage = MATECOMPONENT_OBJREF (storage);
	...
	Serialize components to streams created in the storage
	...
	MateComponent_Storage_commit (corba_storage, ev);
	CORBA_exception_free (ev);
	matecomponent_object_unref (MATECOMPONENT_OBJECT (storage));
}
