Is it possible to intercept method of unnamed instances of interfaces?

[Scott Babcock]

I'm trying to intercept a method defined in an interface. Instances of this interface are created via 'new' with a closure that defines the interface methods:

public interface Foo {

    void bar();

}

public static void main(String[] args) {
    Foo myFoo = new Foo() {
        @Override
        public void bar() {
            System.out.println("FOOBAR");
        }
    };
}

Is it possible to define a transformation to intercept 'bar()' in the myFoo instance?

Yes, this will be conpiled to an anonymous class named Outer$1 which behaves like a regular class. TypeDescription also lets you check if a class is anonymous.
