How to access the top level/enclosing class instance having the instance of the inner class

NOTE: I’m not talking about the way of accessing the enclosing class FROM the inner class, that is not the problem at all. What I’m talking about is the following:

class TopLevel {

    class InnerClass {
    }
}


// in some other class A.java
public void execute(InnerClass ic) {

}

Here, in the execute() method, we have the instance of the InnerClass passed as an argument. So what I actually want is to access the instance of Enclosing class, inside which the InnerClass instances that was passed to execute() was created.

How can this be achieved?
