## Description

This class provides functionality for watching for changes on a given addressbook opened with an EBookClient. Use `e_book_client_get_view()` to create an EBookClientView.

## Details

### struct EBookClientView

    struct EBookClientView {
    };

Contains only private data the should be read and manipulated using the functions below.

Since 3.2

### struct EBookClientViewClass

    struct EBookClientViewClass {
    	/* Signals */
    	void		(*objects_added) (EBookClientView *client_view,
    						 const GSList *objects);
    	void		(*objects_modified) (EBookClientView *client_view,
    						 const GSList *objects);
    	void		(*objects_removed) (EBookClientView *client_view,
    						 const GSList *uids);
    	void		(*progress)		(EBookClientView *client_view,
    						 guint percent,
    						 const gchar *message);
    	void		(*complete)		(EBookClientView *client_view,
    						 const GError *error);
    };

Class structure for the EBookClient class.

`objects_added` () | Signal emitted when contacts are added in the view
`objects_modified` () | Signal emitted when contacts in the view are modified
`objects_removed` () | Signal emitted when contacts are removed from the view
`progress` () | Signal emitted intermittently while loading a view after calling `e_book_client_view_start()`
`complete` () | Notification that loading a view has completed, after calling `e_book_client_view_start()`

Since 3.2

### e_book_client_view_ref_client ()

    struct _EBookClient * e_book_client_view_ref_client     (EBookClientView *client_view);

Returns the "client" associated with `client_view`.

The returned EBookClient is referenced for thread-safety. Unreference the EBookClient with `g_object_unref()` when finished with it.

`client_view` : | an EBookClientView
Returns : | an EBookClient

Since 3.10

### e_book_client_view_get_connection ()

    GDBusConnection *   e_book_client_view_get_connection   (EBookClientView *client_view);

Returns the GDBusConnection used to create the D-Bus proxy.

`client_view` : | an EBookClientView
Returns : | the GDBusConnection. [transfer none]

Since 3.8

### e_book_client_view_get_object_path ()

    const gchar *       e_book_client_view_get_object_path  (EBookClientView *client_view);

Returns the object path used to create the D-Bus proxy.

`client_view` : | an EBookClientView
Returns : | the object path

Since 3.8

### e_book_client_view_is_running ()

    gboolean            e_book_client_view_is_running       (EBookClientView *client_view);

### e_book_client_view_set_fields_of_interest ()

    void                e_book_client_view_set_fields_of_interest
                                                            (EBookClientView *client_view,
                                                             const GSList *fields_of_interest,
                                                             GError **error);

Client can instruct server to which fields it is interested in only, thus the server can return less data over the wire. The server can still return complete objects, this is just a hint to it that the listed fields will be used only. The UID field is returned always. Initial views has no fields of interest and using `NULL` for `fields_of_interest` will unset any previous changes.

Some backends can use summary information of its cache to create artifical objects, which will omit stored object parsing. If this cannot be done then it will simply return object as is stored in the cache.

`client_view` : | an EBookClientView
`fields_of_interest` : | List of field names in which the client is interested. [element-type utf8]
`error` : | return location for a GError, or `NULL`

### e_book_client_view_start ()

    void                e_book_client_view_start            (EBookClientView *client_view,
                                                             GError **error);

Tells `client_view` to start processing events.

`client_view` : | an EBookClientView
`error` : | return location for a GError, or `NULL`

### e_book_client_view_stop ()

    void                e_book_client_view_stop             (EBookClientView *client_view,
                                                             GError **error);

Tells `client_view` to stop processing events.

`client_view` : | an EBookClientView
`error` : | return location for a GError, or `NULL`

### e_book_client_view_set_flags ()

    void                e_book_client_view_set_flags        (EBookClientView *client_view,
                                                             EBookClientViewFlags flags,
                                                             GError **error);

Sets the `flags` which control the behaviour of `client_view`.

`client_view` : | an EBookClientView
`flags` : | the EBookClientViewFlags for `client_view`
`error` : | return location for a GError, or `NULL`

Since 3.4

### e_book_client_view_get_client ()

    struct _EBookClient * e_book_client_view_get_client     (EBookClientView *client_view);

### Warning

`e_book_client_view_get_client` has been deprecated since version 3.10 and should not be used in newly-written code. Use `e_book_client_view_ref_client()` instead.

Returns the "client" associated with `client_view`.

`client_view` : | an EBookClientView
Returns : | an EBookClient. [transfer none]
