## Includes

## 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.

## Functions

### 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.

#### Parameters

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.

#### Parameters

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.

#### Parameters

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.

#### Parameters

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.

#### Parameters

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.

#### Parameters

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` .

#### Parameters

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);

`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` .

#### Parameters

client_view | an EBookClientView |

#### Returns

an EBookClient.

[transfer none]

## Types and Values

### struct EBookClientView

    struct EBookClientView {
    };

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

    struct EBookClientViewClass {
    	/* Signals */
    	void		(*objects_added) (EBookClientView *client_view,
    						 const GSList *objects);
    	void		(*objects_modified) (EBookClientView *client_view,
