java.lang.Objectnet.rim.device.api.lbs.Locator
public final class Locator
Locator is a geocoding service that allows you to obtain location information for an address. You can use
the Locator class to obtain latitudinal and longitudinal information using either an AddressInfo
object for formatted input or a String object for non-formatted input. A successful request for geocode
information return an enumeration of Landmark objects.
Requests for geocode information are synchronous, but can be interrupted by invoking
Locator.cancel(). An application can use the Locator class to make only one request at a time.
Making more than one request results in a MapServiceException.
An application must request geocode information outside of the event dispatch thread.
Requests made on the event dispatch thread will be denied and result in a MapServiceException.
Each request for geocode information is sent to the LBS Locator Server. If a request fails, a
LocatorException is thrown with an error code that indicates the reason for the failure.
If the LBS Map API module is not installed on the BlackBerry device, requests for geocode information will throw
a MapServiceException.
Request results are not cached on the BlackBerry device.
Freeform String geocode request
Returns to landmarkArray an array of Landmark objects that fit the “Waterloo” search criteria.
Landmark[] landmarkArray = Locator.geocode(“Waterloo”, null);

public static Landmark[] geocode(AddressInfo address,
Coordinates startCoords)
throws LocatorException
AddressInfo object as input.
address - The AddressInfo object to use for requesting geocoding information.
Supported fields include: STREET, POSTAL_CODE,
CITY, STATE, COUNTRY or COUNTRY_CODE.startCoords - The Coordinates for starting the search specified in the request. This is used to refine a request
from an initial location starting point. This parameter may be null.
Landmarks. The first array element contains the most relevant Landmark to the locator request.
LocatorException - if the request could not be fulfilled.
To obtain the reason the request is not fulfilled, invoke LocatorException.getErrorCode().
MapServiceException - if the LBS Map API is not installed on the BlackBerry device or if an application makes more than
one request at a time.
IllegalThreadStateException - if a request is made on the event dispatch thread.
IllegalStateException - thrown if there is no valid connectivity to send the request upon.
public static Landmark[] geocode(String freeformString,
Coordinates startCoords)
throws LocatorException
String as input.
freeformString - The search String used as input to request geocode information.startCoords - The Coordinates for starting the search specified in a request. This request uses this data to
refine the starting point. This parameter can be null.
Landmarks. The first array element contains the most relevant Landmark to the locator request.
LocatorException - if the request could not be fulfilled.
To obtain the reason the request is not fulfilled, invoke LocatorException.getErrorCode().MapServiceException - if the LBS Map API is not installed on a BlackBerry device or if an application makes more than
one request at a time.
IllegalThreadStateException - if a request is made on the event dispatch thread.
IllegalStateException - thrown if there is no valid radio/wi-fi connection to send the request to.
public static Landmark[] reverseGeocode(Coordinates coord,
int searchType)
throws LocatorException
Coordinates object.
The reverse geocoding request blocks until it completes, cancels, or times out.
coord - A Coordinates object that contains at least the latitude and longitude.searchType - The type of the search to perform, which can be one of the following:
ADDRESS, COUNTRY, PROVINCE_STATE, POSTAL_CODE, or CITY.
Landmarks.
LocatorException - if the request could not be fulfilled. To obtain the reason the request is not fulfilled,
invoke LocatorException.getErrorCode().
IllegalThreadStateException - if a request is made on the event dispatch thread.
IllegalStateException - thrown if there is no valid radio/wi-fi connection to send the request to.
public static Landmark[] reverseGeocode(int latitude,
int longitude,
int searchType)
throws LocatorException
latitude - The latitude of the address, specified as decimal degrees
to five decimal places, multiplied by 100000.longitude - The longitude of the address, specified as decimal degrees
to five decimal places, multiplied by 100000.searchType - The type of the search to perform, which can be one of the following:
ADDRESS, COUNTRY, PROVINCE_STATE, POSTAL_CODE, or CITY.
LocatorException - If the request could not be fulfilled. To obtain the reason the request is not fulfilled,
invoke LocatorException.getErrorCode().
IllegalThreadStateException - if a request is made on the event dispatch thread.
IllegalStateException - thrown if there is no valid radio/wi-fi connection to send the request to.public static void cancel()
