## Description

This base class makes it easier to write TpSvcClient implementations. Subclasses should usually pass the filters they want and override the D-Bus methods they implement.

For many applications, the provided TpSimpleObserver, TpSimpleApprover and TpSimpleHandler subclasses can be used instead of deriving from this class.

## Details

### TpBaseClient

    typedef struct _TpBaseClient TpBaseClient;

Data structure representing a generic TpSvcClient implementation.

Since 0.11.5

### struct TpBaseClientClass

    struct TpBaseClientClass {
        GObjectClass parent_class;
        TpBaseClientClassObserveChannelsImpl observe_channels;
        TpBaseClientClassAddDispatchOperationImpl add_dispatch_operation;
        TpBaseClientClassHandleChannelsImpl handle_channels;
    };

The class of a TpBaseClient.

The virtual methods `observe_channels`, `add_dispatch_operation` and `handle_channels` can be also implemented by calling `tp_base_client_implement_observe_channels()`, `tp_base_client_implement_add_dispatch_operation()` and `tp_base_client_implement_handle_channels()`. This is compatible with telepathy-glib versions older than 0.11.13.

GObjectClass `parent_class`; | the parent class
TpBaseClientClassObserveChannelsImpl `observe_channels`; | the function called to observe newly-created channels matching this client's observer filter (since 0.11.13)
TpBaseClientClassAddDispatchOperationImpl `add_dispatch_operation`; | the function called to request user approval of unrequested (incoming) channels matching this client's approver filter (since 0.11.13)
TpBaseClientClassHandleChannelsImpl `handle_channels`; | the function called to handle channels matching this client's handler filter (since 0.11.13)

Register a new channel class as Observer.ObserverChannelFilter. The TpBaseClientClass.observe_channels virtual method will be called whenever a new channel's properties match the ones in `filter`.

This method may only be called before `tp_base_client_register()` is called, and may only be called on objects whose class implements TpBaseClientClass.observe_channels.

Register a new channel class as Observer.ObserverChannelFilter. The TpBaseClientClass.observe_channels virtual method will be called whenever a new channel's properties match the ones in `filter`.

This method may only be called before `tp_base_client_register()` is called, and may only be called on objects whose class implements TpBaseClientClass.observe_channels.

If the variant is floating (see `g_variant_ref_sink()`), ownership will be taken, allowing for uses like this:

    tp_base_client_add_observer_filter_vardict (client,
       g_variant_new_parsed ("{ %s: <%s>, %s: <%u>, ... }",
           TP_PROP_CHANNEL_CHANNEL_TYPE, TP_IFACE_CHANNEL_TYPE_TEXT,
           TP_PROP_CHANNEL_TARGET_HANDLE_TYPE, (guint32) TP_HANDLE_TYPE_CONTACT,

The same as `tp_base_client_add_observer_filter()`, but ownership of `filter` is taken by `self`. This makes it convenient to call using `tp_asv_new()`:

    tp_base_client_take_observer_filter (client,
       tp_asv_new (
           TP_PROP_CHANNEL_CHANNEL_TYPE, G_TYPE_STRING,
               TP_IFACE_CHANNEL_TYPE_TEXT,
           TP_PROP_CHANNEL_TARGET_HANDLE_TYPE, G_TYPE_UINT,
               TP_HANDLE_TYPE_CONTACT,

### tp_base_client_set_observer_recover ()

    void                tp_base_client_set_observer_recover (TpBaseClient *self,
                                                             gboolean recover);

Set whether the channel dispatcher should attempt to recover this Observer if it crashes. (This is implemented by setting the value of its Recover D-Bus property.)

Normally, Observers are only notified when new channels appear. If an Observer is set to recover, when it registers with `tp_base_client_register()`, it will also be told about any channels that already existed before it started.

For Observers that are activatable as a D-Bus service, if the Observer exits or crashes while there are any channels that match its filter, it will automatically be restarted by service-activation.

This method may only be called before `tp_base_client_register()` is called, and may only be called on objects whose class implements TpBaseClientClass.observe_channels.

`self` : | a TpBaseClient
`recover` : | the value of the Observer.Recover property

                                                             gboolean delay);

Set whether the channel dispatcher should wait for `tp_observe_channels_context_accept()` or `tp_observe_channels_context_fail()` to be called before calling TpBaseClientClass.add_dispatch_operation on appropriate Approvers.

This is implemented by setting the value of the DelayApprovers D-Bus property.

This method may only be called before `tp_base_client_register()` is called, and may only be called on objects whose class implements TpBaseClientClass.observe_channels.

`self` : | a TpBaseClient
`delay` : | the value of the Observer.DelayApprovers property

### tp_base_client_be_a_handler ()

    void                tp_base_client_be_a_handler         (TpBaseClient *self);

Register `self` as a Client.Handler with an empty list of filters. This is useful if you want to create a client that only handle channels for which it's the PreferredHandler.

This method may only be called before `tp_base_client_register()` is called, and may only be called on objects whose class implements TpBaseClientClass.handle_channels.

### tp_base_client_set_handler_request_notification ()

    void                tp_base_client_set_handler_request_notification
                                                            (TpBaseClient *self);

Indicate that `self` is a Handler willing to be notified about requests for channels that it is likely to be asked to handle. This means that the "request-added" and "request-removed" signals will be fired and `tp_base_client_get_pending_requests()` will return the list of pending requests.

This method may only be called before `tp_base_client_register()` is called, and may only be called on objects whose class implements TpBaseClientClass.handle_channels.

`self` : | a TpBaseClient

Since 0.11.6

### tp_base_client_register ()

    gboolean            tp_base_client_register             (TpBaseClient *self,
                                                             GError **error);

Publish `self` as an available client. After this method is called, as long as it continues to exist, it will receive and process whatever events were requested via the various filters.

Methods that set the filters and other immutable state, such as `tp_base_client_add_observer_filter()`, cannot be called after this one.

`self` : | a TpBaseClient, which must not have been registered with `tp_base_client_register()` yet
`error` : | used to indicate the error if `FALSE` is returned
Returns : | `TRUE` if the client was registered successfully

Since 0.11.5

### tp_base_client_unregister ()

    void                tp_base_client_unregister           (TpBaseClient *self);

Remove this client object from D-Bus, if `tp_base_client_register()` has already been called.

If the object is not registered, this method may be called, but has no effect.

Releasing the last reference to the object also has the same effect as calling this method, but this method should be preferred, as it has more deterministic behaviour.

If the object still exists, `tp_base_client_register()` may be used to attempt to register it again.

`self` : | a client, which may already have been registered with `tp_base_client_register()`, or not

Since 0.11.6

### tp_base_client_get_bus_name ()

    const gchar *       tp_base_client_get_bus_name         (TpBaseClient *self);

Return the bus name of `self`. Note that doesn't mean the client is actually owning this name; for example if `tp_base_client_register()` has not been called yet or failed.

`self` : | a TpBaseClient
Returns : | the bus name of the client

Since 0.11.5

### tp_base_client_get_object_path ()

    const gchar *       tp_base_client_get_object_path      (TpBaseClient *self);

Return the object path of `self`. Note that doesn't mean the client is actually registered on this path; for example if `tp_base_client_register()` has not been called yet or failed.

`self` : | a TpBaseClient
Returns : | the object path of the client

Since 0.11.5

### tp_base_client_get_dbus_daemon ()

    TpDBusDaemon *      tp_base_client_get_dbus_daemon      (TpBaseClient *self);

Return the "dbus-daemon" construct-only property, which represents the D-Bus connection used to export this client object.

The returned object's reference count is not incremented, so it is not necessarily valid after `self` is destroyed.

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

Since 0.11.11

### tp_base_client_get_name ()

    const gchar *       tp_base_client_get_name             (TpBaseClient *self);

Return the "name" construct-only property, which is used as part of the bus name and object path.

`self` : | a TpBaseClient
Returns : | the value of "name"

Since 0.11.11

### tp_base_client_get_uniquify_name ()

    gboolean            tp_base_client_get_uniquify_name    (TpBaseClient *self);

Return the "uniquify-name" construct-only property; if this is true, the bus name and object path will be made unique by appending a suffix that includes the D-Bus unique name and a per-process counter.

`self` : | a TpBaseClient
Returns : | the value of "uniquify-name"

Since 0.11.11

### tp_base_client_get_account_manager ()

    TpAccountManager *  tp_base_client_get_account_manager  (TpBaseClient *self);

### Warning

`tp_base_client_get_account_manager` is deprecated and should not be used in newly-written code. New code should not use this function, it may return `NULL` in the case `self` was constructed with a TpSimpleClientFactory.

Return the "account-manager" construct-only property, which is the account manager used to look up or create TpAccount objects.

The returned object's reference count is not incremented, so it is not necessarily valid after `self` is destroyed.

It is not guaranteed that any particular features are prepared on this object; enable and wait for features with `tp_proxy_prepare_async()`.

`self` : | a TpBaseClient
Returns : | the value of "account-manager". [transfer none]

Since 0.11.14

### tp_base_client_set_channel_factory ()

    void                tp_base_client_set_channel_factory  (TpBaseClient *self,
                                                             TpClientChannelFactory *factory);

### Warning

`tp_base_client_set_channel_factory` is deprecated and should not be used in newly-written code. since 0.15.5. The factory is taken from "account-manager".

Change the value of the "channel-factory" property. It can't be changed once `self` has been registered.

`self` : | a TpBaseClient
`factory` : | an object implementing the TpClientChannelFactoryInterface interface

### Warning

`tp_base_client_get_channel_factory` is deprecated and should not be used in newly-written code. since 0.15.5. The factory is taken from "account-manager".

Return the "channel-factory" property.

`self` : | a TpBaseClient

## Property Details

### The `"account-manager"` property

      "account-manager"          TpAccountManager*     : Read / Write / Construct Only

### Warning

`TpBaseClient:account-manager` is deprecated and should not be used in newly-written code. New code should not use this property, it may be `NULL` in the case `self` was constructed with a TpSimpleClientFactory.

Account manager for this base client, used to look up or create TpAccount objects. This may be specified in the constructor in order to get existing TpAccount objects.

It is not guaranteed that any of its features have been prepared, and it is not necessary to wait for any features before specifying this property in the constructor.

Clients that interact with the TpAccount should usually set this property instead of "dbus-daemon". Doing this will ensure that each account, connection or contact is represented by a single TpAccount, TpConnection or TpContact object, shared between all the cooperating modules that have the same TpAccountManager.

If the "dbus-daemon" is set to the result of `tp_dbus_daemon_dup()`, then this property defaults to the result of `tp_account_manager_dup()`.

This property may be `NULL` initially, but will always be non-`NULL` after the TpBaseClient has been constructed.

It is an error to specify both a non-`NULL` account manager, and a non-`NULL` "dbus-daemon" that is not the same as the account manager's "dbus-daemon".

Since 0.11.14

### The `"channel-factory"` property

      "channel-factory"          GObject*              : Read / Write / Construct Only

### Warning

`TpBaseClient:channel-factory` is deprecated and should not be used in newly-written code. since 0.15.5. The factory is taken from "account-manager".

The object implementing the TpClientChannelFactoryInterface interface that will be used to create channel proxies. While `tp_base_client_register()` has not yet been called, this property can be changed using `tp_base_client_set_channel_factory()`.

If no channel factory is specified then TpAutomaticProxyFactory is used.

Since 0.13.2

### The `"dbus-daemon"` property

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

TpDBusDaemon object encapsulating this object's connection to D-Bus. Read-only except during construction.

This property can't be `NULL` after construction.

Since 0.11.14 this property may be `NULL` or unspecified in `g_object_new()`, but only if "account-manager" is provided instead, in which case its "dbus-daemon" property will be used.

Since 0.11.5

### The `"factory"` property

      "factory"                  TpSimpleClientFactory*  : Read / Write / Construct Only

Factory for this base client, used to look up or create TpAccount objects.

Since 0.15.5

### The `"name"` property

      "name"                     gchar*                : Read / Write / Construct Only

The name of the client. This is used to register the D-Bus service name and object path of the service.

This property can't be `NULL`.

Default value: NULL

Since 0.11.5

### The `"uniquify-name"` property

      "uniquify-name"            gboolean              : Read / Write / Construct Only

If `TRUE`, `tp_base_client_register()` will append an unique token to the service bus name and object path to ensure they are unique.

Default value: FALSE

Since 0.11.5

## Signal Details

### The `"request-added"` signal

    void                user_function                      (TpBaseClient     *self,
                                                            TpAccount        *account,
                                                            TpChannelRequest *request,
                                                            gpointer          user_data)      : Has Details

Emitted when a channels have been requested, and that if the request is successful, they will probably be handled by this Handler.

This signal is only fired if `tp_base_client_set_handler_request_notification()` has been called on `self` previously.

`self` : | a TpBaseClient
`account` : | the TpAccount on which the request was made, with `TP_ACCOUNT_FEATURE_CORE`, and any other features added via `tp_base_client_add_account_features()` or `tp_simple_client_factory_add_account_features()`, prepared if possible
`request` : | a TpChannelRequest having its object-path defined but is not guaranteed to be prepared.
`user_data` : | user data set when the signal handler was connected.

Since 0.11.6

### The `"request-removed"` signal

    void                user_function                      (TpBaseClient     *self,
                                                            TpChannelRequest *request,
                                                            gchar            *error,
                                                            gchar            *message,
                                                            gpointer          user_data)      : Has Details

Emitted when a request has failed and should be disregarded.

This signal is only fired if `tp_base_client_set_handler_request_notification()` has been called on `self` previously.

`self` : | a TpBaseClient
`request` : | the TpChannelRequest being removed
`error` : | the name of the D-Bus error with which the request failed.
`message` : | any message supplied with the D-Bus error.
`user_data` : | user data set when the signal handler was connected.
