Say you have

class A {
}

class B {
}

One type dependency is “method parameter”:

class A {
}

class B {
  public void M(A a) {
  }
}

Another is “method returns”:

class A {
}

class B {
  public A M() {
  }
}

Then C, an adapter from A to B, could be identified by a class that exhibits both of the above dependency characteristics:

class C {
  public B M(A a) {
  }
}

I just seems like something that could be approached with some formal methods and I’d be interested to read about them if they are out there?
