   +----GDataAccessHandler

Prerequisites

GDataAccessHandler requires GDataEntry.

Known Implementations

GDataAccessHandler is implemented by GDataCalendarCalendar, GDataDocumentsEntry, GDataDocumentsFolder, GDataDocumentsPresentation, GDataDocumentsSpreadsheet and GDataDocumentsText.

Description

GDataAccessHandler is an interface which can be implemented by GDataEntrys which can have their permissions controlled by an access control list (ACL). It has a set of methods which allow the GDataAccessRules for the access handler/entry to be retrieved, added, modified and deleted, with immediate effect.

When implementing the interface, classes must implement an is_owner_rule function.

Details

GDataAccessHandler

typedef struct _GDataAccessHandler GDataAccessHandler;

All the fields in the GDataAccessHandler structure are private and should never be accessed directly.

Since 0.3.0


GDataAccessHandlerIface

typedef struct {
	GTypeInterface parent;

	gboolean (*is_owner_rule) (GDataAccessRule *rule);
} GDataAccessHandlerIface;

The class structure for the GDataAccessHandler interface.

GTypeInterface parent;

the parent type

is_owner_rule ()

a function to return whether the given GDataAccessRule has the role of an owner (of a GDataAccessHandler).

Since 0.3.0


gdata_access_handler_get_rules ()

GDataFeed *         gdata_access_handler_get_rules      (GDataAccessHandler *self,
                                                         GDataService *service,
                                                         GCancellable *cancellable,
                                                         GDataQueryProgressCallback progress_callback,
                                                         gpointer progress_user_data,
                                                         GError **error);

Retrieves a GDataFeed containing all the access rules which apply to the given GDataAccessHandler. Only the owner of a GDataAccessHandler may view its rule feed.

If cancellable is not NULL, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error G_IO_ERROR_CANCELLED will be returned.

A GDATA_SERVICE_ERROR_PROTOCOL_ERROR will be returned if the server indicates there is a problem with the query.

For each rule in the response feed, progress_callback will be called in the main thread. If there was an error parsing the XML response, a GDataParserError will be returned.

self :

a GDataAccessHandler

service :

a GDataService

cancellable :

optional GCancellable object, or NULL

progress_callback :

a GDataQueryProgressCallback to call when a rule is loaded, or NULL. [scope call]

progress_user_data :

data to pass to the progress_callback function. [closure]

error :

a GError, or NULL

Returns :

a GDataFeed of access control rules, or NULL; unref with g_object_unref(). [transfer full]

Since 0.3.0


gdata_access_handler_insert_rule ()

GDataAccessRule *   gdata_access_handler_insert_rule    (GDataAccessHandler *self,
                                                         GDataService *service,
                                                         GDataAccessRule *rule,

                                                         GError **error);

Inserts rule in the access control list of the GDataAccessHandler.

The service will return an updated version of the rule, which is the return value of this function on success.

If cancellable is not NULL, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error G_IO_ERROR_CANCELLED will be returned.

If the rule is marked as already having been inserted a GDATA_SERVICE_ERROR_ENTRY_ALREADY_INSERTED error will be returned immediately (there will be no network requests).

If there is an error inserting the rule, a GDATA_SERVICE_ERROR_PROTOCOL_ERROR error will be returned.

self :

a GDataAccessHandler

service :

a GDataService

rule :

the GDataAccessRule to insert

cancellable :

optional GCancellable object, or NULL

error :

a GError, or NULL

Returns :

an updated GDataAccessRule, or NULL; unref with g_object_unref(). [transfer full]

gdata_access_handler_update_rule ()

Updates rule in the access control list of the GDataAccessHandler.

The service will return an updated version of the rule, which is the return value of this function on success.

If cancellable is not NULL, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error G_IO_ERROR_CANCELLED will be returned.

If there is an error updating the rule, a GDATA_SERVICE_ERROR_PROTOCOL_ERROR error will be returned.

a GDataAccessHandler

service :

a GDataService

rule :

the GDataAccessRule to update

cancellable :

optional GCancellable object, or NULL

gdata_access_handler_delete_rule ()

gboolean            gdata_access_handler_delete_rule    (GDataAccessHandler *self,

Deletes rule from the access control list of the GDataAccessHandler.

If cancellable is not NULL, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error G_IO_ERROR_CANCELLED will be returned.

If there is an error deleting the rule, a GDATA_SERVICE_ERROR_PROTOCOL_ERROR error will be returned, unless the rule was the owner's rule; in which case, GDATA_SERVICE_ERROR_FORBIDDEN will be returned without any network activity.
