Build

As the project is managed with Maven you simply clone it and issue mvn install or mvn package inside the clone's directory.

git clone git://github.com/kohanyirobert/sggc.git
cd sggc/
mvn package
# and/or

Usage

Geocoding

// acquire a geocoder instance
Geocoder<Request, Response> geocoder = Geocoders.geocoder();

// create a geocoding request
String address = "1600 Amphitheatre Parkway Mountain View, CA 94043";
Request request = Requests.create(address);

// then you pass this to the geocoder to get a response
Response response = geocoder.geocode(request);

// inspect the response
if (response.status() == Status.OK)
  for (Result result : response.results())
     ...

Generics

// define a *packer* function
Function<String, Request> packer = new Function<String, Request>() {
  @Override public Request apply(String input) {
    return Requests.create(input);
  }
};

// and an *unpacker*
Function<Response, List<String>> unpacker = new Function<Response, List<String>>() {
  @Override public List<String> apply(Response input) {
    return Lists.transform(input.results(), new Function<Result, String>() {
      @Override public String apply(Result input) {
        return input.formattedAddress();
      }
    });
  }
};

// then obtain the custom geocoder
Geocoder<String, List<String>> geocoder = Geocoders.geocoder(packer, unpacker);
