How to use Solrj annotations to index Lat/Long

I have an object that I want to add to my Solr server that I've annotated using solrj's @Field annotation, but I can't find any documentation about what Java data type to use for Solr's location type. Here is my Bean I want to add:

@Field
private UUID id;
@Field
LatLonType location; // what should the Java data type of this field be???
@Field
private EventType eventType;
@Field
private int maxCapacity;
@Field
private int minCapacity;
@Field
private double price;
@Field
private Date startDate;
@Field
private Date endDate;

Any ideas?

The best solution to the problem is if you want to use addBean() method(s) you'd create a property on the object and annotate that like so:

public class MyBean {

   private double latitude;
   private double longitude;

   public String getLocation() {
      return latitude + "," + longitude;
   }

   @Field
   public void setLocation( String value ) {
      String[] split = value.split(",");
      latitude = Double.parseDouble(split[0]);
      longitude = Double.parseDouble(split[1]);
   }
}

The appropriate type on Java side is a simple String with both the lat and lon separated by a comma, e.g. "1.2,3.4".
