Hi, Im trying to define multiple OneToMany Relationships to the same class and I do not know what is the best way to do it.
I have classses A and B:

class A{

long id;
List<B> leftList;
List<B> rightList;

}

B would be

OPTION 1
class B{

long id;
A leftA;
A rightA;
}

or

OPTION 2
class B{
long id;
A linkToA;
String type; // WHere type could be or "RIGHT" or "LEFT"
}


Which option is better to define class B?
How I have to define the relationship in B to use linkToA+type as a FK to A and Hibernate could handle it properly?

Thanks in advance!!
