I have four classes A, B, C, D. Now, I have one object of B and one object of C in every object of A. In B i have a list and in c i have a list of object of class D.
Now, for every object in D i want to access the object of B.

Every class extend MinimalEObjectImpl.Container class.

Let's write in down:

class A{
protected B b;
protected C c;
A(){
super();
}
}

class B{
List<Integer> al;
B(){
super();
}}

class C{
List<D> al;
C(){
super();
}
}

class D{
List<Integer> al;
D(){
super();
}
}

now, object of a contains object of b and c and object of c contains a list of objects of D.
I want to get the specification of the list that is present in object of B to give some values in the list of an object of type D.
How can i do that?

Thanks in advance.

There's a bit of hint that this is a modeling question. But it's worded in such a way that it's most a riddle...

Yes, This is EMF modelling based project.
I will try to explain a little more..
I have a class A and for each of that class object we have one, one object of class B and C linked to that object of class A.
Now, in B, I have a list of something.
In c, I have a list of objects of type D class.
In D class, I have some properties for which i need to access the list present in B.
How can i do that?

A
B
C
D
