Constructor Detail

OSMGeoHandler

public OSMGeoHandler(GeoCoordinate where,
                     int radius)
Creates the handler for the geocoder's xml stream. It needs the data provided, as it does not use delegation to filter out locations.

Parameters:
where - position around which is coded
radius - maximum distance to the location
