belongs that is suitable for
organizing the providers while displaying them in an user
interface.
This is a pure virtual method - a subclass must provide an implementation.

gboolean goa_provider_build_object (GoaProvider *provider
,GoaObjectSkeleton *object
,GKeyFile *key_file
,const gchar *group
,GDBusConnection *connection
,gboolean just_added
,GError **error
);
This method is called when construction account GoaObject from configuration data - it basically provides a way to add provider-specific information.
The passed in object
will have a GoaAccount interface
set. Implementations should validate and use data from key_file
to
add more interfaces to object
.
Note that this may be called on already exported objects - for example on configuration files reload.
This is a pure virtual method - a subclass must provide an implementation.
|
A GoaProvider. |
|
The GoaObjectSkeleton that is being built. |
|
The GKeyFile with configuation data. |
|
The group in key_file to get data from. |
|
The GDBusConnection used by the daemon to connect to the message bus. |
|
Whether the account was newly created or being updated. |
|
Return location for error or NULL . |
Returns : |
TRUE if data was valid, FALSE if error is set. |
GoaObject * goa_provider_add_account (GoaProvider *provider
,GoaClient *client
,GtkDialog *dialog
,GtkBox *vbox
,GError **error
);
This method brings up the user interface necessary to create a new
account on client
of the type for provider
, interacts with the
user to get all information needed and creates the account.
The passed in dialog
widget is guaranteed to be visible with vbox
being empty and the only visible widget in dialog
's content
area. The dialog has exactly one action widget, a cancel button
with response id GTK_RESPONSE_CANCEL. Implementations are free to
add additional action widgets, as needed.
If an account was successfully created, a GoaObject for the
created account is returned. If dialog
is dismissed, NULL
is
returned and error
is set to GOA_ERROR_DIALOG_DISMISSED
. If an
account couldn't be created then error
is set. In some cases,
for example, when the credentials could not be stored in the
keyring, a GoaObject can be returned even if error
is set.
The caller will always show an error dialog if error
is set unless
the error is GOA_ERROR_DIALOG_DISMISSED
.
Implementations should run the default main loop while
interacting with the user and may do so using e.g. gtk_dialog_run()
on dialog
.
This is a pure virtual method - a subclass must provide an implementation.
|
A GoaProvider. |
|
A GoaClient. |
|
A GtkDialog. |
|

|
Return location for error or NULL . |
Returns : |

with g_object_unref() ) or NULL if error is set. |
void goa_provider_set_preseed_data (GoaProvider *provider
,GVariant *preseed_data
);
Sets the "preseed-data" property to feed any information already collected that can be useful when creating a new account.
If the preseed_data
GVariant is floating, it is consumed to allow
'inline' use of the g_variant_new()
family of functions.
|
The GoaProvider |
|
A GVariant of type a{sv} |
GVariant * goa_provider_get_preseed_data (GoaProvider *provider
);
Gets the GVariant set through the "preseed-data" property.
|
The GoaProvider |
Returns : |
A GVariant that is known to be valid until the property is overridden or the provider freed. [transfer none] |
gboolean goa_provider_refresh_account (GoaProvider *provider
,GoaClient *client
,GoaObject *object
,GtkWindow *parent
,GError **error
);
This method brings up the user interface necessary for refreshing
the credentials for the account specified by object
. This
typically involves having the user log in to the account again.
Implementations should use parent
(unless NULL
) as the transient
parent of any created windows/dialogs.
Implementations should run the default main loop while interacting with the user.
This is a pure virtual method - a subclass must provide an implementation.
|
A GoaProvider. |
|
A GoaClient. |
|
A GoaObject with a GoaAccount interface. |
|
Transient parent of dialogs or NULL . [allow-none]
|
|
Return location for error or NULL . |

void goa_provider_ensure_credentials (GoaProvider *provider
,GoaObject *object
,GCancellable *cancellable
,GAsyncReadyCallback callback
,gpointer user_data
);
Ensures that credentials for object
are still valid.
When the result is ready, callback
will be called in the the goa_provider_ensure_credentials_finish()
to get the result
of the operation.
This is a virtual method where the default implementation simply
throws the GOA_ERROR_NOT_SUPPORTED
error. A subclass may provide
another implementation.
|
A GoaProvider. |
|
A GoaObject with a GoaAccount interface. |
|
A GCancellable or NULL . [allow-none]
|
|
The function to call when the request is satisfied. |

,GError **error
);
Like goa_provider_ensure_credentials()
but blocks the
calling thread until an answer is received.

|
A GCancellable or NULL . [allow-none]
|
|
Return location for error or NULL . |
Returns : |
TRUE if the credentials for the passed GoaObject are valid, FALSE if error is set. |
guint goa_provider_get_credentials_generation
(GoaProvider *provider
);
Gets the generation of credentials being used for the provider.
Implementations should bump this number when changes are introduced that may render existing credentials unusable.
For example, if an additional scope is requested (e.g. access to contacts data) while obtaining credentials, then this number needs to be bumped since existing credentials are not good for the added scope.
This is a virtual method where the default implementation returns 0.
|
A GoaProvider. |
Returns : |
The current generation of credentials. |
#define GOA_PROVIDER_EXTENSION_POINT_NAME "goa-backend-provider"
Extension point for GoaProvider implementations.
void goa_provider_get_all (GAsyncReadyCallback callback
,gpointer user_data
);
Creates a list of all the available GoaProvider instances.
When the result is ready, callback
will be called in the the goa_provider_get_all_finish()
to get the result of the operation.
See goa_provider_get_for_provider_type()
for details on how the providers
are found.
|
The function to call when the request is satisfied. |
|
Pointer to pass to callback . |
GoaProvider * goa_provider_get_for_provider_type (const gchar *provider_type
);
Returns a GoaProvider for provider_type
(if available).
If provider_type
doesn't contain any "/", a
GOA_PROVIDER_EXTENSION_POINT_NAME
extension for provider_type
is looked up
and the newly created GoaProvider, if any, is returned.
If provider_type
contains a "/", a
GOA_PROVIDER_FACTORY_EXTENSION_POINT_NAME
extension for the first part of
provider_type
is looked up. If found, the GoaProviderFactory is used
to create a dynamic GoaProvider matching the second part of provider_type
.
|
A provider type. |
Returns : |
A GoaProvider (that must be freed
with g_object_unref() ) or NULL if not found. [transfer full]
|
"preseed-data"
property"preseed-data" GVariant* : Read / Write
An GVariant of type a{sv} storing any information already collected that can be useful when creating a new account. For instance, this can be useful to reuse the HTTP cookies from an existing browser session to skip the prompt for username and password in the OAuth2-based providers by passing a GVariant with the following contents:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
{ "cookies": [ { "domain": "example.com", "name": "LSID", "value": "asdfasdfasdf" }, { "domain": "accounts.example.com", "name": "SSID", "value": "asdfasdfasdf" } ] } |
Unknown or unsupported keys will be ignored by providers.
Allowed values: GVariant<a{sv}>
Default value: NULL
