Proper use of Column.ForeignKeyAction.CASCADE

Question

If I have a relation like this, and what I want is that whenever I call delete() on an User, the vehicle field is also deleted.

@Table (name = "Users")
public class User extends Model {
    @Column(name = "Name", unique = true, onUniqueConflict = Column.ConflictAction.REPLACE) name;
    @Column(name = "Vehicle") Vehicle vehicle;
}

@Table (name = "Vehicles")
public class Vehicle extends Model {
    @Column(name = "Name", unique = true, onUniqueConflict = Column.ConflictAction.REPLACE) name;
}

I think this can be accomplished by using onDelete = Column.ForeignKeyAction.CASCADE on Vehicle.name but I'm not so sure so I'll just go ahead and ask.
