ActionScript 3.0 :: Dynamically Loading Interface Implementation Class?
Jun 14, 2010
I am working on a project were I'd like to implement a sort of MVC. The idea is the following: have a Viewer app that connects to a database and reads the object to be displayed (based on some ID); have a Setter app that connects to the database and sets the object to be displayed for a particular ID.
What i am trying to do is have an interface that declares common methods for the Object class (like draw, etc.) and have implementations of that interface be loaded dynamically from the database in the Viewer.

I have created the following classes for sharing images. They implement an interface, but I need a way of switching between them with user interaction. I've done it the following way:As you can see, service 1 and service 2 implement iSharingServices, and inherit from PolimorphSharing.PolimorphSharing is simply and an abstract class that implements the methods I want public from Service 1 and Service 2. Those methods will then be overridden on the Service 1 and Service 2. Because I need a way to switch the service in runtime, I've created a gateway class that inherits from PolimorphSharing. I can then call it the following way:
private var sharingService:PolimorphSharing = new SharingServicesGW('svc1').createService();
This all works flawlessly, and I can now switch between services with no problem whatsoever. However, I feel there's something wrong about it, so I would like to ask you guys for some advice on how to better implement this.
UPDATE:
Just adding some more insight to this. Basically the idea here is for my client to be able to upload images with various different public sharing services such as imageshack, imgur etc. I want my client to be able to select the service in which the image is to be published to (hence the "switching between them with user interaction" bit of the question.
The method that does the uploading bit, is requestShareImage(), processResults() simply turns whatever gets returned to a unique format, so my client can read off it always the same way. getObject() is my accessor, and onIOError will handle exceptions with any of the public API's

In C#, it's possible implementing interface methods without making implementing method as public. For example,
void ITest.SomeMethod()
{
// ...
}
Is there equivalent for ActionScript3?

Is there a way to generate an instance of a class that implements an interface based on the name of the class?
I am trying:
var ClassReference:Object = getDefinitionByName("movement.OuterSpaceMovement") as IMovement;
var m:IMovement = new ClassReference as IMovement;
trace("startup..." + m);
-But I am getting an error message ReferenceError: Error #1065 (OuterSpaceMovement) not defined.
I have several classes that implement the same interface (IMovement) but I need to be able to generate new instances of these classes and then pass these instances as a datatype (IMovement datatype) to other classes...
So then I tried:
var ClassReference:Class = getDefinitionByName("OuterSpaceMovement") as Class;
var m:IMovement = new ClassReference() as IMovement;
and this doesn't seem to work...but the following
var m:IMovement = new OuterSpaceMovement();

I'm trying to load a RSL library into a flash animation developed with Flash CS5 IDE, that extends a custom class and implements an interface. I have reduced the problem to the simplest setup and find that I can have my main class extend another class or implement an interface, but not do both at the same time if I want to load an RSL.I have a very simple class to extend:
import flash.display.Sprite;
public class MySprite extends Sprite
{[ code]...........
but if I want both I get the VerifyError: Error #1014 with MySprite not found and ReferenceError: Error #1065.

Working in a very large Flash application, previously in AS2/CS3 I would have a setup like the following:
root.swf-- modules---- code_a.swf---- code_b.swf-- views---- view_a.swf---- view_b.swfUsing _exclude.xml files, I could exclude the classes defined in code_a and code_b from the ouptut .swf of view_a and view_b. root.swf would be responsible for loading the code modules before view_a or view_b, ensuring that class definitions that view_a and view_b depended on existed.
The Problem:We've recently migrated to using Actionscript 3/CS5. *_exclude.xml files no longer exist. To get the same functionality as above, I've tried the following: My setup now looks something like:
root.swf-- modules---- class_a.as---- class_b.as-- views---- view_a.swf---- view_b.swfUse mxmlc to compile root.swf, view_a.swf and view_b.swf, passing it -externs option to specify classes that will be loaded externally (the two classes in modules).
This ensures that the class is excluded from the compiled swf.Use compc to compile class_a.as and class_b.as into classes.swf, using -directory=true to access library.swf for external loading.However,when I try running one of the two view files which depend on classes.swf, I get runtime errors telling me that a class definition is not present.
Current Workaround
I've devised a workaround which I'm currently not happy with as it's backwards to the modular approach that I was previously using:Rather than loading the code modules, I statically link all class definitions required by child movies intoroot.swf. When building root.swf, I use the -link-report option of mxmlc to provide a list of included classes. When building child swfs, I can the use -load-externs to ensure that class definitions that already exist will not be included in the compile output.
Is there a way that anyone is aware of to replicate the AS2/_exclude.xml solution that I had using AS3/CS5?

i am working on a project where i have some common code which i import in different movie clips and different files the code is in actionscript 2 in an external .as file. this is not a class its just a bucnh of functions and temporary variables.Problem is when i use the check syntax button or auto format button i get the following error."ActionScript 2.0 class scripts may only define class or interface constructs."this used to work fine in flash 8 but it always gives this error since i started using flash 9.the code works fine too. its just that my auto format button and the check syntax doesn't work.

I'm trying to publish a swf with Flash CS3.
I have one .fla file and two .as files. I think my problem is I don't know how to set the path for the action scripts. All three files are in the same directory
The files:
dtd.fla
TransformItem.as
TransformManager.as
The error: The class or interface 'gs.TransformManager' could not be loaded.
dtd.fla code appears to have an appropriate import: import gs.TransformManager; var manager_obj = new TransformManager([], onTransformEvent, true, false, false, false, false, true, true);
TransformManager.as code appears to have an appropriate import: import gs.TransformItem;

I've created simple swf with interface:
public class Test extends MovieClip implements ITest
{
public function Test()
{
[Code]....
So if I have test.swf in the same directory(local way) it work's fine. But if I'm placing it on the dedicated server: (event.target.content as ITest) returns null. However, I can access speak() without interface like this event.target.content.speak("a!");

I'm doing a simple link code. I've tried many diferrent ways to do this but this error keeps comming up saying The class or interface could not be loaded...
home_btn.addEventListener(MouseEvent.CLICK, gotoURL);
function gotoURL(event:MouseEvent):Void{
navigateToURL(new URLRequest("my site"));}
This is the most recent method I've tried in doing this. I've tried changing the publishing settings of the document to and from Action Script 3.0- using an import command. But thats too complicated.

Can I implement more than one interface to the same class?One option is to make interface A extend interface B and than have my class inplementing interface A. Is there any other way that I can implement two or more interfaces directly to the same class?

Quick question. Does a class have to implement a interface directly to be accepted, or can it be a child of a parent class that implements it. so If I pass a child object into a method that only accepts IOBJECT, but the child class parent implements IOBJECT. will child object be accepted ?

I am getting an error with RegExp class at my flash document. I am using an Action Script 2.0 at my document. Is RegExp class is not supported in AS1/AS2 ?
My code is as follows
function validateEmailAddress(emailString:String):Boolean {
var myRegEx:RegExp = /(w|[_.-])+@((w|-)+.)+w{2,4}+/;
var myResult:Object = myRegEx.exec(emailString);
if(myResult == null) {return false;}return true;
} if(validateEmailAddress(email) == false) {
contacterror = "Error ! Please Enter Valid Email Address";}
If RegExp not supported in ActionScript 2.0 then how to validate email address at ActionScript 2.0 ?

whats the purpose of having to have an extra class such as abstract class in Flash where the methods has no implementation,but the subclasses declare those implementations.The advantage of having the methods declared in subclass than the superclass is that it would not affect the other subclasses when there are certain changes.That makes me wonder, isn't it better not to extend(inherit) empty methods but directly create a class as its own? unless there is something that the child could use from parent.Anyone could give me examples of how applicable using abstract classes/interfaces?

I think I understand how to make a interface but the problem is im unsure as to how to add it to my existing code! To make a interface (as far as i know) You can create classes such as mainScreen, intructions and so on. Ok i get that, make the classes then add ther buttons from the library i these classes. But i followed a tutorial bu Emmanuel Feronto, and adapted that to the needs of my game.
So im unsure as how to add these 'Screens' to my current class, the I currently only have 1 class, Main which currently has 300 lines of code, and i dont know how to break it up into smaller classes. Thats the problem i think, The main is quite large, normally i have heard people keep this clear... But then say i made a bland main, and added the screens into that then how do i make the main that makes the game play on the play button?

Not sure if this is possible but I would like to reflect a swf or swc file selected by the user at runtime to find any classes that implement a certain interface. Can this be done or do you actually need a reference to the class you want to reflect using describeType();
Note - this would be done in actionscript.
