Direct methods access of interfaced object

Question

Hi, gurus!
My situation like this:
IHost.as:
Code:
public interface IHost {
    function doSomething() : void;
Host.as:
Code:
import IHost;
public class Host implements IHost {
    public function doSomething() : void { trace("doSomething"); }
    public function doAnotherThing() : void { trace("doAnotherThing"); }
    public function loadChild() : void {
        var loader : Loader = new Loader();
        with (loader.contentLoaderInfo) {
                addEventListener(SecurityErrorEvent.SECURITY_ERROR, onChild);
                addEventListener(IOErrorEvent.IO_ERROR, onChild);
                addEventListener(Event.COMPLETE, onChild);
        var context : LoaderContext = new LoaderContext();
        context.applicationDomain = ApplicationDomain.currentDomain;
        context.securityDomain = SecurityDomain.currentDomain;
        loader.load(new URLRequest("Child.swf"), context);
    public function onChild(event : Event) : void {
        event.target.content.testIt(this);
Child.as:
Code:
import IHost;
public class Child extends Sprite {
    public function testIt(host : IHost) : void {
        // call method 1
        host.doSomething(); // It works...
        // call method 2
        Object(host).doAnotherThing(); // It also works!!!
And the question is - how I can allow "call method 1", but deny "call method 2" from loaded objects? I cant declare doAnotherThing method as private - i need it in other chasses (not loaded) to be public...

Answer 1

just what are you asking?
if you pass a host instance (and the testIt() method in the Child class should be passed a Host instance not an IHost instance), all the public methods of the Host class will be available to that instance.
i'm not sure what role casting that instance as an object is supposed to have.
