Implemented Interfaces

AgAccount implements GInitable.

Description

An AgAccount is an object which represents an account. It provides a method for enabling/disabling the account and methods for editing the account settings.

Accounts are created by AgManager with ag_manager_create_account(), and deleted by AgAccount with ag_account_delete(). These operations, and any other operations which modify the account settings, must be followed by ag_account_store() before the changes are committed to the database.

Example 1. Creating a new AgAccount

GMainLoop *main_loop = NULL;

gboolean account_cleanup_idle (gpointer user_data)
{
    AgManager *manager;
    AgAccount *account = AG_ACCOUNT (user_data);
    manager = ag_account_get_manager (account);

    g_object_unref (account);
    g_object_unref (manager);

    g_main_loop_quit (main_loop);

    return FALSE;
}

void account_stored_cb (AgAccount *account,
                        const GError *error,
                        gpointer user_data)
{
    AgManager *manager = AG_MANAGER (user_data);

    if (error != NULL)
    {
        g_warning ("Account with ID '%u' failed to store, with error: %s",
                   account->id,
                   error->message);
    }
    else
    {
        g_print ("Account stored with ID: %u", account->id);
    }

    /* Clean up in an idle callback. */
    g_idle_add (account_cleanup_idle, account);
    g_main_loop_run (main_loop);
}

void store_account (void)
{
    AgManager *manager;
    GList *providers;
    const gchar *provider_name;
    AgAccount *account;

    main_loop = g_main_loop_new (NULL, FALSE);
    manager = ag_manager_new ();
    providers = ag_manager_list_providers (manager);
    g_assert (providers != NULL);
    provider_name = ag_provider_get_name ((AgProvider *) providers->data);
    account = ag_manager_create_account (manager, provider_name);

    ag_provider_list_free (providers);

    /* The account is not valid until it has been stored. */
    ag_account_store (account, account_stored_cb, (gpointer) manager);
}
