Tizen Native API  5.5
Geocoder

This provides APIs for Geocoder Service.

The Maps Geocoding API allows translating an address to its geographical location defined in terms of latitude and longitude; the input can be a qualified, structured address or a free form single search text with full or partial address information.
The Maps Reverse Geocoding API allows to inverse translating a geographical location (longitude, latitude) to an address; it can be used to answer the question "Where am I?".

Typedef Documentation

typedef bool(* maps_service_geocode_cb)(maps_error_e result, int request_id, int index, int total, maps_coordinates_h coordinates, void *user_data)

Called once for each position coordinates converted from the given address information.

The Maps Service invokes this callback while iterating through the list of obtained coordinates of the specified place.
If search is failed, the value of total is 0 and coordinates is NULL.

Since :
2.4
Remarks:
The parameter coordinates must be released using maps_coordinates_destroy().
This error code will be reported.
MAPS_ERROR_NONE
MAPS_ERROR_OUT_OF_MEMORY
MAPS_ERROR_INVALID_PARAMETER
MAPS_ERROR_NOT_FOUND.
Parameters:
[in]resultThe result of request
[in]request_idThe ID of request
[in]indexThe current index of coordinates in result set, start from 0
[in]totalThe total number of results
[in]coordinatesThe coordinates of the place
[in]user_dataThe user data passed from maps_service_geocode() or maps_service_geocode_inside_area()
Returns:
true to continue with the next iteration of the loop,
false to break out of the loop
Precondition:
maps_service_geocode() or maps_service_geocode_inside_area() will invoke this callback.

maps_service_geocode()
maps_service_geocode_inside_area()
maps_service_cancel_request()
typedef bool(* maps_service_multi_reverse_geocode_cb)(maps_error_e result, int request_id, int total, maps_address_list_h address_list, void *user_data)

Called when respond to a request of multi reverse geocoding.

The Maps Service invokes this callback once when gets the response from map service provider.
The value of total is same with requested coordinates list size. Even though one of address is not provided valid address handle is retrieved.

Since :
3.0
Remarks:
You can get the respective address information of address_list using maps_address_list_foreach().
This error code will be reported.
MAPS_ERROR_NONE
MAPS_ERROR_OUT_OF_MEMORY
MAPS_ERROR_INVALID_PARAMETER
MAPS_ERROR_NOT_FOUND.
Parameters:
[in]resultThe result of request
[in]request_idThe ID of request

[in]address_listThe converted address list from the requested coordinates list
[in]user_dataThe user data pointer passed from maps_service_multi_reverse_geocode()
Returns:
true to continue with the next iteration of the loop,
false to break out of the loop
Precondition:
maps_service_multi_reverse_geocode() will invoke this callback.
