How model circular dependency in dagger2?

Question

How can I model circular dependency using dagger2? Lets say we have only two classes. First injection is via constructor and second is via method as in example below:

class A{
    private B b;

    @Inject
    public A(B b)
    {
        this.b = b;
    }
}

class B{
    private A a;

    @Inject
    public B() { }

    @Inject
    public void injectA(A a)
    {
        this.a = a;
    }
}

Answer 1

You can use lazy injection:

class B{
    private Lazy<A> a;

    @Inject
    public B(Lazy<A> a) {
       this.a = a;
    }
}

Alternatively you can inject Provider<A>, but be aware that provider returns new instance of A each time Provider::get is invoked (assuming default scope), while Lazy::get returns the same instance.
