Details

struct GeocodeForward

struct GeocodeForward;

All the fields in the GeocodeForward structure are private and should never be accessed directly.


struct GeocodeForwardClass

struct GeocodeForwardClass {
};

All the fields in the GeocodeForwardClass structure are private and should never be accessed directly.


geocode_forward_new_for_string ()

GeocodeForward *    geocode_forward_new_for_string      (const char *str);

Creates a new GeocodeForward to perform forward geocoding with. The string is in free-form format.

str :

a string containing a free-form description of the location

Returns :

a new GeocodeForward. Use g_object_unref() when done.

geocode_forward_new_for_params ()

GeocodeForward *    geocode_forward_new_for_params      (GHashTable *params);

Creates a new GeocodeForward to perform geocoding with. The GHashTable is in the format used by Telepathy, and documented on Telepathy's specification site.

See also: XEP-0080 specification.

params :

a GHashTable with string keys, and GValue values. [transfer none][element-type utf8 GValue]

Returns :

a new GeocodeForward. Use g_object_unref() when done.

geocode_forward_set_answer_count ()

void                geocode_forward_set_answer_count    (GeocodeForward *forward,
                                                         guint count);

Sets the number of requested results to count.

forward :

a GeocodeForward representing a query

count :

the number of requested results

geocode_forward_search_async ()

void                geocode_forward_search_async        (GeocodeForward *forward,
                                                         GCancellable *cancellable,
                                                         GAsyncReadyCallback callback,
                                                         gpointer user_data);

Asynchronously performs a forward geocoding query using a web service. Use geocode_forward_search() to do the same thing synchronously.

When the operation is finished, callback will be called. You can then call geocode_forward_search_finish() to get the result of the operation.

forward :

a GeocodeForward representing a query

cancellable :

optional GCancellable forward, NULL to ignore.

callback :

a GAsyncReadyCallback to call when the request is satisfied

user_data :

the data to pass to callback function

geocode_forward_search_finish ()

GList *             geocode_forward_search_finish       (GeocodeForward *forward,
                                                         GAsyncResult *res,
                                                         GError **error);

Finishes a forward geocoding operation. See geocode_forward_search_async().

forward :

a GeocodeForward representing a query

res :

a GAsyncResult.

error :

a GError.

Returns :

A list of places or NULL in case of errors. Free the returned list with g_list_free() when done. [element-type GeocodePlace][transfer container]

geocode_forward_search ()

GList *             geocode_forward_search              (GeocodeForward *forward,
                                                         GError **error);

Gets the result of a forward geocoding query using a web service.

forward :

a GeocodeForward representing a query

error :

a GError

Returns :

A list of places or NULL in case of errors. Free the returned list with g_list_free() when done. [element-type GeocodePlace][transfer container]
