Class GeophileSpatialIndexJoinPlan

java.lang.Object

com.apple.foundationdb.record.spatial.geophile.GeophileSpatialIndexJoinPlan

@API(EXPERIMENTAL)
public class GeophileSpatialIndexJoinPlan
extends Object

Something like a query plan for joining spatial indexes. This is not a real RecordQueryPlan because the signature of the cursor can't match until queries support actual joins.
