what is the purpose of @Edge and @Vertex annotation in OrientDB?

I saw these annotations on Spring Data Orientdb project and I'm wondering if I can use it on java pojo objects to create vertices and relationships.

The scenario will be something like that:

@Vertex
public class User{

@Edge
public class Follow {

OrientGraph orientGraph = factory.getTx();
User george = new User();
User richard = new User();
Follow follow = new Follow();
orientGraph.addEdge(null, george, richard, follow);

It doesn't work because the addEdge method needs 2 Vertex classes and Edge class. Maybe annotations is not suited for this.

I use the orientdb Studio and seems to be very simple to create Objects that inherit from V(Vertex) and E(Edge) classes and link each others. I'm wondering something like that in java code.

Does anyone has same use case scenario? Possible solutions or approaches? Thanks

What is your final needs? Do you want to connect vertexes with an edge? Have you seen docs regarding object binding: http://orientdb.com/docs/last/Object-2-Record-Java-Binding.html ? – Oleksandr Gubchenko Jun 28 '16 at 07:09
Yes I need to connect two vertex with an edge. I saw the doc but cannot figure out how to do it. – daniele montagni Jun 28 '16 at 07:24
You could look [this](http://stackoverflow.com/questions/26548408/can-i-register-my-java-classes-as-orientdb-vertices-and-or-edges). Hope it helps – Alessandro Rota Jun 28 '16 at 08:09
Already checked out but it's a sort of workaround. I'm looking for some standard or official approach – daniele montagni Jun 28 '16 at 10:39
