Blackberry引路蜂地图开发示例：地址查询
引路蜂地图API中同样提供了地址查询，路径查询，本地搜索，IP地址查询，地址反编码（通过经纬度查地名）等。 地址查询（或称为地址编码）是将输入的地名（如南京林业大学）转换成对应的经纬度坐标然后将其显示在地图上

}所有的地图服务都是采用异步方式调用，在调用RasterMap.getLocation(address)前，需要设置好返回结果时的回调函数RasterMap.setGeocodingListener，回调函数接口定义为IGeocodingListener。 回调方法为public void done(String query,MapPoi
