## Description

## Details

### struct EDataFactory

    struct EDataFactory {
    	EDBusServer parent;
    	EDataFactoryPrivate *priv;
    };

Contains only private data that should be read and manipulated using the functions below.

Since 3.4

### struct EDataFactoryClass

    struct EDataFactoryClass {
    	EDBusServerClass parent_class;

    	GType backend_factory_type;

    	const gchar *factory_object_path;
    	const gchar *data_object_path_prefix;
    	const gchar *subprocess_object_path_prefix;
    	const gchar *subprocess_bus_name_prefix;

    	/* Virtual methods */
    	GDBusInterfaceSkeleton *
    			(*get_dbus_interface_skeleton)
    						(EDBusServer *server);
    	const gchar * (*get_factory_name) (EBackendFactory *backend_factory);
    	void		(*complete_open) (EDataFactory *data_factory,
    						 GDBusMethodInvocation *invocation,
    						 const gchar *object_path,
    						 const gchar *bus_name,
    						 const gchar *extension_name);

    	gpointer reserved[15];
    };

### e_data_factory_ref_backend_factory ()

    EBackendFactory *   e_data_factory_ref_backend_factory  (EDataFactory *data_factory,
                                                             const gchar *backend_name,
                                                             const gchar *extension_name);

Returns the EBackendFactory for "`backend_name`:`extension_name`", or `NULL` if no such factory is registered.

The returned EBackendFactory is referenced for thread-safety. Unreference the EBackendFactory with `g_object_unref()` when finished with it.

`data_factory` : | an EDataFactory
`backend_name` : | a backend name
`extension_name` : | an extension name
Returns : | the EBackendFactory for `hash_key`, or `NULL`

Since 3.6

### e_data_factory_get_registry ()

    ESourceRegistry *   e_data_factory_get_registry         (EDataFactory *data_factory);

Returns the ESourceRegistry owned by `data_factory`.

`data_factory` : | an EDataFactory
Returns : | the ESourceRegistry

Since 3.14

### e_data_factory_construct_path ()

    gchar *             e_data_factory_construct_path       (EDataFactory *data_factory);

Returns a new and unique object path for a D-Bus interface based in the data object path prefix of the `data_factory`

`data_factory` : | an EDataFactory
Returns : | a newly allocated string, representing the object path for the D-Bus interface.

Since 3.14
