Add @Query to Entity properties #27

Open gjrwebber opened 9 years ago

gjrwebber commented 9 years ago

It would be nice to be able to add the @Query annotation above a referenced Collection of @Entities and have it fetched when the Object is loaded from the graph.

Eg


@Entity
//@NodeEntity if using Neo4j annotations.
public class Person {

    private String firstName;
    private Location myLocation;
    //... 

    @Query("graph.V().has('firstName', @firstName)")
    private Set<Person> peopleWithSameName;

    @Query(value = "SELECT expand(in('located_at')) FROM (SELECT FROM Location WHERE [latitude,longitude,$spatial] NEAR [@myLocation.latitude,@myLocation.longitude,{\"maxDistance\":0.05f}])", nativeQuery = true)
    private Set<Person> peopleNearMe;

    // ...

}
