Question

I have an existing google app engine java application runs with jpa and now i am trying to move to objectify for many different purposes.

Current application has the below representation of the entities.

Class Parent{
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Key key;

    @OneToMany(cascade=CascadeType.ALL, mappedBy="parent")
    private List<Child> childs = null;
}

Class Child{
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Key key;

    @ManyToOne  
    private Parent parent;

}

How can i get the above representation in Objectify? I am using objectify4.
I have seen @Parent, but it seems not possible to load the list of child entities directly while fetching a parent?

Thanks,

Ramesh.V
