GClientGeocoder [class]

http://www.google.com/apis/maps/docu­mentation/

Version 2 （2006.6新規）

This class is used to communicate directly with Google servers to obtain geocodes for user specified addresses. In addition, a geocoder maintains its own cache of addresses, which allows repeated queries to be answered without a round trip to the server.

Constructor

Constructor Description
GClientGeocoder(cache?) Creates a new instance of a geocoder that talks directly to Google servers. The optional cache parameter allows one to specify a custom client-side cache of known addresses. If none is specified, a GFactualGeocodeCache is used. (Since 2.55)

Methods

Methods Return Value Description
getLatLng(address, callback) none Sends a request to Google servers to geocode the specified address. If the address was successfully located, the user-specified callback function is invoked with a GLatLng point. Otherwise, the callback function is given a null point. In case of ambiguous addresses, only the point for the best match is passed to the callback function. (Since 2.55)
getLocations(address, callback) none Sends a request to Google servers to geocode the specified address. A reply that contains status code, and if successful, one or more Placemark objects, is passed to the user-specified callback function. Unlike the GClientGeocoder.getLatLng method, the callback function may determine the reasons for failure by examining the code value of the Status field. (Since 2.55)
getCache() GGeocodeCache Returns currently used geocode cache, or null, if no client-side caching is performed. (Since 2.55)
setCache(cache) none Sets a new client-side caching. If this method is invoked with cache set to null, client-side caching is disabled. Setting a new cache discards previously stored addresses. (Since 2.55)
reset() none Resets the geocoder. In particular this method calls the GGeocodeCache.reset method on the client-side cache, if one is used by this geocoder. (Since 2.55)
