## Properties

      "dbus-daemon"              TpDBusDaemon*         : Read / Write / Construct Only

## Description

This factory constructs various TpProxy subclasses as well as TpContact, which guarantees that at most one instance of those objects will exist for a given remote object or contact. It also stores the desired features for contacts and each type of proxy.

Note that the factory will not prepare the desired features: it is the caller's responsibility to do so. By default, only core features are requested.

Currently supported classes are TpAccount, TpConnection, TpChannel and TpContact. Those objects should always be acquired through a factory, rather than being constructed directly.

One can subclass TpSimpleClientFactory and override some of its virtual methods to construct more specialized objects. See TpAutomaticClientFactory for a subclass which automatically constructs subclasses of TpChannel for common channel types.

An application using its own factory subclass would look like this:

    int main(int argc, char *argv[])
    {
      TpSimpleClientFactory *factory;
      TpAccountManager *manager;

      g_type_init ();

      factory = my_factory_new ();
      manager = tp_account_manager_new_with_factory (factory);
      tp_account_manager_set_default (manager);

      ...
      tp_proxy_prepare_async (manager, am_features, callback, user_data);
      ...
    }

The call to `tp_account_manager_set_default()` near the beginning of `main()` will ensure that any libraries or plugins which also use Telepathy (and call `tp_account_manager_dup()`) will share your TpAccountManager.

The class structure for TpSimpleClientFactory.

TpSimpleClientFactory maintains a cache of previously-constructed proxy objects, so the implementations of `create_account`, `create_connection`, `create_channel`, and `create_contact` may assume that a new object should be created when they are called. The default implementations create unadorned instances of the relevant classes; subclasses of the factory may choose to create more interesting proxy subclasses.

The default implementation of `dup_channel_features` returns TP_CHANNEL_FEATURE_CORE, plus all features passed to `tp_simple_client_factory_add_channel_features()` by the application. Subclasses may override this method to prepare more interesting features from subclasses of TpChannel, for instance. The default implementations of the other `dup_x_features` methods behave similarly.

`create_connection` () | create a TpConnection; see `tp_simple_client_factory_ensure_connection()`

### tp_simple_client_factory_new ()

    TpSimpleClientFactory * tp_simple_client_factory_new    (TpDBusDaemon *dbus);

Creates a new TpSimpleClientFactory instance.

`dbus` : | a TpDBusDaemon
Returns : | a new TpSimpleClientFactory

### tp_simple_client_factory_get_dbus_daemon ()

    TpDBusDaemon *      tp_simple_client_factory_get_dbus_daemon

`self` : | a TpSimpleClientFactory object
Returns : | the value of the "dbus-daemon" property. [transfer none]

### tp_simple_client_factory_ensure_account ()

    TpAccount *         tp_simple_client_factory_ensure_account
                                                            (TpSimpleClientFactory *self,
                                                             const gchar *object_path,

Returns a TpAccount proxy for the account at `object_path`. The returned TpAccount is cached; the same TpAccount object will be returned by this function repeatedly, as long as at least one reference exists.

Note that the returned TpAccount is not guaranteed to be ready; the caller is responsible for calling `tp_proxy_prepare_async()` with the desired features (as given by `tp_simple_client_factory_dup_account_features()`).

`self` : | a TpSimpleClientFactory object
`object_path` : | the object path of an account
`immutable_properties` : | the immutable properties of the account, or `NULL`. [transfer none][element-type utf8 GObject.Value]
`error` : | Used to raise an error if `object_path` is not valid
Returns : | a reference to a TpAccount; see `tp_account_new()`. [transfer full]

Return a zero-terminated GArray containing the TpAccount features that should be prepared on `account`.

`self` : | a TpSimpleClientFactory object
`account` : | a TpAccount
Returns : | a newly allocated GArray. [transfer full][element-type GLib.Quark]

Since 0.15.5

### tp_simple_client_factory_add_account_features ()

    void                tp_simple_client_factory_add_account_features

Add `features` to the desired features to be prepared on TpAccount objects. Those features will be added to the features already returned be `tp_simple_client_factory_dup_account_features()`.

It is not necessary to add `TP_ACCOUNT_FEATURE_CORE` as it is already included by default.

Note that these features will not be added to existing TpAccount objects; the user must call `tp_proxy_prepare_async()` themself.

`self` : | a TpSimpleClientFactory object
`features` : | an array of desired features, ending with 0; `NULL` is equivalent to an array containing only 0. [transfer none][array zero-terminated=1][allow-none]

Since 0.15.5

### tp_simple_client_factory_add_account_features_varargs ()

    void                tp_simple_client_factory_add_account_features_varargs
                                                            (TpSimpleClientFactory *self,

                                                             ...);

The same as `tp_simple_client_factory_add_account_features()`, but with a more convenient calling convention from C.

`self` : | a TpSimpleClientFactory
`feature` : | the first feature
`...` : | the second and subsequent features, if any, ending with 0

### tp_simple_client_factory_ensure_connection ()

Returns a TpConnection proxy for the connection at `object_path`. The returned TpConnection is cached; the same TpConnection object will be returned by this function repeatedly, as long as at least one reference exists.

Note that the returned TpConnection is not guaranteed to be ready; the caller is responsible for calling `tp_proxy_prepare_async()` with the desired features (as given by `tp_simple_client_factory_dup_connection_features()`).

`self` : | a TpSimpleClientFactory object
`object_path` : | the object path of a connection
`immutable_properties` : | the immutable properties of the connection. [transfer none][element-type utf8 GObject.Value]
`error` : | Used to raise an error if `object_path` is not valid

Add `features` to the desired features to be prepared on TpConnection objects. Those features will be added to the features already returned be `tp_simple_client_factory_dup_connection_features()`.

It is not necessary to add `TP_CONNECTION_FEATURE_CORE` as it is already included by default.

Note that these features will not be added to existing TpConnection objects; the user must call `tp_proxy_prepare_async()` themself.

Returns a TpChannel proxy for the channel at `object_path` on `connection`. The returned TpChannel is cached; the same TpChannel object will be returned by this function repeatedly, as long as at least one reference exists.

Note that the returned TpChannel is not guaranteed to be ready; the caller is responsible for calling `tp_proxy_prepare_async()` with the desired features (as given by `tp_simple_client_factory_dup_channel_features()`).

Returns a TpContact representing `identifier` (and `handle`) on `connection`. The returned TpContact is cached; the same TpContact object will be returned by this function repeatedly, as long as at least one reference exists.

Note that the returned TpContact is not guaranteed to be ready; the caller is responsible for calling `tp_connection_upgrade_contacts()` with the desired features (as given by `tp_simple_client_factory_dup_contact_features()`).

For this function to work properly, `tp_connection_has_immortal_handles()` must return `TRUE` for `connection`.
