matecomponent-storagematecomponent-storage — Abstract implementation of the MateComponent::Storage interface |
void matecomponent_storage_copy_to (MateComponent_Storage src
,MateComponent_Storage dest
,CORBA_Environment *ev
);
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)); }
void matecomponent_storage_copy_to (MateComponent_Storage src
,MateComponent_Storage dest
,CORBA_Environment *ev
);
Implements a pure CORBA method for copying one storage into another, this is used by several MateComponentStorage implemetations where a fast case localy copy cannot work.
