On my personal project, I'm starting to use tons of interfaces and I got to thinking how nice it'd be to know which of my class' members serve which of its interfaces. For instance, my class might implement 5 different interfaces, but I only want to see the members that play a role in 1 of those.
View 3 RepliesI hsve a setp where a couple of classes inherit from a base class (events, plus common math). All derived classes implement the same set of methods. Another part of the program wants to instantiate any of these classes. So far I was creating empty functions in the base class and overriding them. Could an interface improve on that? I tried to list the common functions in an interface and use that as a datatype, but that would not let me use functions that the base class already inherits, in particular event dispatcher. Would I need to add these to the interface?
View 4 RepliesI'm trying, without success, to make a class to manage a XML file configuration. This class has some methods to get a XML file and return a object E4X (XML) to user (programmer).
Then I created a package:
components.datahandlers
And the class to handler XML config file:
XMLConfigHandler.as
The code, that class, is below:
package components.datahandlers{
import flash.net.URLLoader;
import flash.net.URLRequest;
import flash.xml.XMLDocument;
import flash.events.*;
import flash.errors.*;
public class XMLConfigHandler {

The trace above shows: NOT. But if I get a trace inside onLoaded method, it is show: YES. Why "xmlLoaded" property don't change to YES? How can I make this works?

View 2 RepliesFor some reason, in the past few days, the auto complete feature doesn't work well when I'm creating a new class file. I'm trying to write a new class which uses away3D, and even though the auto-complete works well when I start a new AS3 file, it just doesn't work as far as away3D is concerned when I try to create a new AS3 Class file. Other features of the auto-complete don't work as well, for some reason.

View 1 RepliesHow to use interfaces?
View 2 RepliesOur company is about to create and distribute (and possibly to sell ) the utility to convert Silverlight apps to its equivalents on Flash.For this purpose we're writing our own AS3-compiler. The compiler for correct work must know how to interact with the classes
backed into the FlashPlayer. The Flex Builder solves it by using the playerglobal.swc that is the part of its distribution package.As far as I know we have no right to redistribute the separate playerglobal.swc without the rest of Flex SDK.
And here is the question: Tehnically we're able to learn all the class interfaces defined inside of the playerglobal.swc with the help of e.g. the plugin ExportSWC (shipped for FlashDevelop) and redeclare them inside of our own swc (e.g. named PlayerGlobalInterfaces. swc) or somehow else.It would be enough for the correct work of our AS3-compiler without the need of using playerglobal.swc at all. But I'm not sure would it violate any copyrights or not?
Is there any way to create a sort of interface for variables? In other words to enforce a class to create and use a variable if they implement an interface or subclass something?
View 1 RepliesWhat I was told, which sparked my curiosity on this topic:Java gui classes can implement hundreds of Listeners and Callbacks and many books teach you to implement all these interfaces in your gui class. Alternatively, these aspects can be implemented in inner classes, so methods called by that listeners do not get mixed up.'d like to know how to do this in ActionScript, which doesn't have inner classes, but has private classes. But, I don't think I fully realize what inner classes are about, so I'm merely trying to wrap my head around the situation where I would use them to organize a class' methods by their usages.

View 2 RepliesDoes anybody know a way to apply an Interface to ObjectProxy, so that you don't have to declare the Interface implementations within the proxy?In other words, if the purpose of ObjectProxy is to proxy the Object in question (passing requests for properties and methods silently to the embedded Object), is it possible to tell the interface "hey, the functions you are looking for are already proxied, so don't bug me about them!"[code]But the function declarations kinda defeat the purpose of using ObjectProxy to begin with... I'd like the Interface to just "know" that "nemesis" is managed by the proxy, but still use the Interface for displaying context-help.which is how to code the context help so people using my MeatwadProxy will see context-help for the Meatwad class it contains?(And yes, I can already hear DrkStr and ASWC snickering at me in the background for continuing to believe in ActionScripts Proxy class. I also believe in Santa Claus, so there!)

View 8 RepliesShould each button get a class and a listener, or should I dump everything into one Object and use e.target.name to figure out what is getting clicked? That way I can just use one listener, but then I won't be able to recycle anything. I could probably work around that though.
View 1 RepliesI am trying to get a handle on interfaces with AS3 and am kind of at a sticking point. Someone tried to explain them to me using legos and conceptually I get the idea of consistent interaction. Where I seem to get stuck is, I don't really see how the implementation of interfaces accomplishes this.

What's the best way around this problem with interfaces?
public interface ITest {
function set testField(test:String):void;
}[code]......
Test does have a setter for testField (an implicit one).I don't want to define an explicit one for every single field I have defined in my interface.There doesn't seem to be a way to define getters/setters in interfaces (or the syntax just escapes me).Do I have to do this explicit getter/setter nonsense in order to use interfaces in this way?

I'm making a game which loads map .swfs at runtime. The maps will contain graphics and code, which can both vary from map to map. I've decided to make all the maps implement an interface, so they can all be used in the same way by the game. I'm using a .swc to contain the interface, like in this page.
I can get classes to work in the .swc, but not interfaces!

The following code seems to create an ambiguity for the compiler (please see error commented near the bottom). Is it not possible to have getters and setters split between interfaces?

From what I read, interfaces are basically classes for methods, right? If two classes implements the same interface, then they should both have methods described in the interface.
Now, how is this useful? Let's say I want to call foo()

I have two interfaces that declare functions with the same name but incompatible signatures:
interface IDog
{
function bark() : void;
}
[code]....
1) Missing 'public' qualifiers in the class definition were a typo. I fixed it.
2) I missed an additional requirement that interfaces CAN'T be modified (for the purpose of this question). In the real project they're defined in two different libraries that are a part of a large project. Multiple classes implement both interfaces (separately). So, any changes of interfaces will require cascading updates of all those classes, recompilation, testing, etc. So, I wanted first to find out if there was a solution without such intrusive modifications. It doesn't seem there is.
Let us assume I have classes "Main", "Sub1" and "Sub2". I also have interface "Inter".[code] Basically, I want the constructor function of any class implementing "Inter" to take the same parameters, and thus avoid initialization errors. (So as that the code above gives a compiler error) With any other function,[code]But As the constructor name differs from function to function, I cannot do this.

I would like people to be able to change this custom scrollItem class, but as the scroller class has some interaction with this scrollItem class (sets id etc), I have the scrollItem class implement an interface to guarantee the presence of the required methods.This works fine, but only if I keep the type of the scrollingItem class within the scroller class. I would prefer to substitute in the interface type for each scrolling item. However, I cant, as the interface is not a DisplayObject. I can get around this by casting the interface type as a DisplayObject whenever it needs to do DisplayObject type things, but this seems like a hideous hack.
