AgAccountService

AgAccountService — Account settings for a specific service

Functions

Types and Values

Description

The AgAccountService object provides access to the account settings for a specific service type. It is meant to be easier to use than the AgAccount class because it hides the complexity of the account structure and gives access to only the limited subset of account settings which are relevant to a service.

To get an AgAccountService one can use the AgManager methods ag_manager_get_account_services() or ag_manager_get_enabled_account_services(), which both return a GList of account services. Note that if the AgManager was instantiated for a specific service type, these lists will contain only those account services matching that service type. Another way to get an AgAccountService is to instantiate one using ag_account_service_new(): this is useful if one already has an AgAccount instance.

This is intended to be a convenient wrapper over the accounts settings specific for a service; as such, it doesn't offer all the editing possibilities offered by the AgAccount class, such as enabling the service itself: these operations should ideally not be performed by consumer applications, but by the account editing UI only.

Example 2. Querying available e-mail services

AgManager *manager;
GList *services, *list;

// Instantiate an account manager interested in e-mail services only.
manager = ag_manager_new_for_service_type ("e-mail");

// Get the list of enabled AgAccountService objects of type e-mail.
services = ag_manager_get_enabled_account_services (manager);

// Loop through the account services and do something useful with them.
for (list = services; list != NULL; list = list->next)
{
    AgAccountService *service = AG_ACCOUNT_SERVICE (list->data);
    GVariant *v_server, *v_port, *v_username;
    gchar *server = NULL, *username = NULL;
    gint port;
    AgAccount *account;

    v_server = ag_account_service_get_variant (service, "pop3/hostname", NULL);
    if (v_server != NULL)
        server = g_variant_dup_string (v_server, NULL);

    v_port = ag_account_service_get_variant (service, "pop3/port", NULL);
    if (v_port != NULL)
        port = g_variant_get_int16 (&v_port);

    // Suppose that the e-mail address is stored in the global account
    // settings; let's get it from there:
    account = ag_account_service_get_account (service);
    ag_account_select_service (NULL);
    v_username = ag_account_get_variant (account, "username", NULL);
    if (v_username != NULL)
        username = g_variant_dup_string (&v_username);

    ...

    g_free (username);
    g_free (server);
}
  

User applications (with the notable exception of the accounts editing application) should never use account services which are not enabled, and should stop using an account when the account service becomes disabled. The latter can be done by connecting to the “changed” signal and checking if ag_account_service_get_enabled() still returns TRUE. Note that if the account gets deleted, it will always get disabled first; so, there is no need to connect to the “deleted” signal; one can just monitor the “changed” signal.

Functions

ag_account_service_new ()

AgAccountService *
ag_account_service_new (AgAccount *account,
                        AgService *service);

Constructor. If service is NULL, the returned object will operate on the global account settings.

Parameters

account

an AgAccount.

[transfer full]

service

an AgService supported by account .

[transfer full][allow-none]

Returns

a new AgAccountService; call g_object_unref() when you don't need this object anymore.


ag_account_service_get_account ()

AgAccount *
ag_account_service_get_account (AgAccountService *self);

Get the AgAccount associated with self .

Parameters

self

the AgAccountService.

 

Returns

the underlying AgAccount. The reference count on it is not incremented, so if you need to use it beyond the lifetime of self , you need to call g_object_ref() on it yourself.

[transfer none]


ag_account_service_get_service ()

AgService *
ag_account_service_get_service (AgAccountService *self);

Get the AgService associated with self .

Parameters

self

the AgAccountService.

 

Returns

the underlying AgService. The reference count on it is not incremented, so if you need to use it beyond the lifetime of self , you need to call ag_service_ref() on it yourself.

[transfer none]


ag_account_service_get_enabled ()

gboolean
ag_account_service_get_enabled (AgAccountService *self);

Checks whether the underlying AgAccount is enabled and the selected AgService is enabled on it. If this method returns FALSE, applications should not try to use this object.

Parameters

self

the AgAccountService.

 

Returns

TRUE if the service is enabled, FALSE otherwise.


ag_account_service_get_value ()

AgSettingSource
ag_account_service_get_value (AgAccountService *self,

                              GValue *value);

ag_account_service_get_value has been deprecated since version 1.4 and should not be used in newly-written code.

Use ag_account_service_get_variant() instead.

Gets the value of the configuration setting key : value must be a GValue initialized to the type of the setting.

Parameters

self

the AgAccountService.

 

key

the name of the setting to retrieve.

 

value

an initialized GValue to receive the setting's value.

[inout]

Returns

one of AgSettingSource: AG_SETTING_SOURCE_NONE if the setting is not present, AG_SETTING_SOURCE_ACCOUNT if the setting comes from the account configuration, or AG_SETTING_SOURCE_PROFILE if the value comes as predefined in the profile.


ag_account_service_set_value ()

void
ag_account_service_set_value (AgAccountService *self,
                              const gchar *key,
                              const GValue *value);

ag_account_service_set_value has been deprecated since version 1.4 and should not be used in newly-written code.

Use ag_account_service_set_variant() instead.

Sets the value of the configuration setting key to the value value . If value is NULL, then the setting is unset.

Parameters

self

the AgAccountService.

 

key

the name of the setting to change.

 

value

a GValue holding the new setting's value.

[allow-none]

ag_account_service_get_variant ()

                                AgSettingSource *source);

Gets the value of the configuration setting key .

Parameters

self

the AgAccountService.

 

key

the name of the setting to retrieve.

 

source

a pointer to an AgSettingSource variable which will tell whether the setting was retrieved from the accounts DB or from a service template.

[allow-none][out]

Returns

a GVariant holding the setting value, or NULL. The returned GVariant is owned by the account, and no guarantees are made about its lifetime. If the client wishes to keep it, it should call g_variant_ref() on it.

[transfer none]

Since: 1.4


ag_account_service_set_variant ()

void
ag_account_service_set_variant (AgAccountService *self,
                                const gchar *key,
                                GVariant *value);

Sets the value of the configuration setting key to the value value . If value has a floating reference, the account will take ownership of it. If value is NULL, then the setting is unset.

Parameters

self

the AgAccountService.

 

key

the name of the setting to change.

 

value

a GVariant holding the new setting's value.

AgAuthData *
ag_account_service_get_auth_data (AgAccountService *self);

Reads the authentication data stored in the account (merging the service-specific settings with the global account settings) and returns an AgAuthData structure.
