ModelGeoValue class

Define a model GeoValue that stores location information.

The base value is given as value. If not given, latitude and longitude are set to 0.

This can be passed to the server for searching by GeoHash.

位置情報を保存するGeoValueをモデルとして定義します。

ベースの値をvalueとして与えます。与えられなかった場合緯度・経度が0としてセットされます。

これをサーバーに渡すことでGeoHashによる検索が可能です。
