ActionScript 3.0 :: What Happens If Override Internal Method In Different Package
Aug 29, 2009
Well, basically, you know the question already What bugs me is that I cannot get an answer to this because compiler doesn't like overriding internal functions in different packages, but, I would like to know what you think it should do, if it would have compiled?
I.e. imagine: I have foo.bar:A class and foo.abc:B class. Then foo.abc:B extends foo.bar:A.
foo.bar:A defines internal function f(). foo.abc:B overrides internal function f(). Now, the question: Can foo.abc.C call foo.abc:B#f()?
I'am trying to import an actionscript file in a internal package in my project. From Java and am used to this to like this import Services.myClass. But the IDE doesn't suggest any classes when I type import Services. So how can I import my AbstractIdManager.as file? Inside this actionscript file, there is a public class named AbstractIdManager which extends EventDispatcher My project structure looks like this: I want to use the AbstactIdManager class in my View videochat.mxml
Is it possible for a class to override it's own methods at runtime? I know this is possible to do in JavaScript by simply assigning a new function to the method name, but this doesn't appear to work in AS3.
Example: Let's say I have a DisplayObject with many accessors and methods. The user is allowed to load a dynamic library that overrides several of the functions and methods in the DisplayObject. As author of the DisplayObject, I have no idea what methods the user's library is going to override... only that they can. IS this possible?
The only thing I can come up with so far is to literally override every single method and accessor in the DisplayObject, then performing a check whenever they get called:
I'm using flash to draw objects, then I export them and use them from flex, and I'm a beginner in flash.
I'm trying to do the override a method from the MovieClip I created. The method I'm trying to override is stop() method. I didn't write a single line of code, my movie clip is created using entirely the flash interface. I figured out how to add actions to the movie clip when a frame is reached but I'm stucked now when I'm trying to override a MovieClip method.
Is it possible to override/replace a method of a class in AS3? When I say "replace", I don't mean subclass it and override it. I mean I literally want to replace the existing method with my own. For instance, AS3 has the built-in HTMLLoader class which has a load method. I want to say, in essence: HTMLLoader.load = function() { trace("Overridden"); }; Therefore, when *anybody* makes a new HTMLLoader object and calls the load method, it will call my method instead.
I've tried a couple things, and so far I've gotten this far: HTMLLoader.prototype.load = function() { trace("Overridden") }; And I compile it with -as3=false -es=true -strict=false. The problem is it doesn't override the already-existing load method. It looks in the class first before looking in the prototype, thus making it not work. There must be a way. Even if I can't override it, can I proxy it like a decorator in Python or a macro in LISP? (So mine gets called then it gets called.)
override a custom class method with a function expression? For instance, if I want to change the destination of a button on the fly, I could theoretically type:
Code: var new_destination:Function = function(evt:Event):void{ go_to_new_place();}; myButtonClass.mouse_clicked = new_destination;
but unfortunately that generates an error because the class method "mouse_clicked" is already defined in my class (with the eventListener tied to it). I tried using the "override" keyword in the Function Expression but that didn't work either.
I have two classes, both in the same package, one of which parses xml and adds a value to the second via an internal set method. This initially works fine but as soon as add a public get method to the second class I get an error (1059: Property is read-only).
The problem goes away if I make both methods public or internal but in this situation I would like to have one of each. Is this possible? I thought I had done this in the past without any problems but maybe not.
I've a custom itemRenderer for my datagrid. To set the actual data I use the following method:
override public function set data(side:Object):void{ ... }
As soon as I use this function the cell doesn't show up any item Editor anymore. Why is that? When I remove this function the itemEditor is working but with the wrong initialization data.
I always have a question about override custom event. I am not sure why or what do to inside override function. I searched google but didn't get too many feedbacks. EDIT: My projects seem work fine even though I use my custom event without override. Anyone could explain it?
when i write prototype method and declare a variable inside the prototype method. this is fine but as sonn as i declare another variable with the same name i get an error. conflict with "variable" namespace internal. i've contact other users and they claim they don't get this same issue. i'm using flash CS3, i have flash player 10 installed but cs3 only supports up to 9 so i have 9 selected. and i'm using AS3. this is some code you can use to test to see if you get this issue:
I am having troubles passing an x and y argument into a package function that creates a projectile on stage at the tank.gun's x and y.I have attached a zip of the code I am working on.[code]
I'm running into this weird thing with ASDoc. It will only document one package function per package.For example.I have these two functions:
gs.util.printf gs.util.ftrace
In these files:
gs/util/printf.as gs/util/ftrace.as
The only function that get's documented in ASDocs is "printf". But I know it can do more than one. As an example, in the livedocs [URL] There are more than one functions documented.
C:demoABC.as: Error: A file found in a source-path must have the same package structure '', as the definition's package, 'demo'.Where is wrong above command?
This is with Flexbuilder 3.2, Eclipse 3.3.2.I am moving my development environment to a new machine. Actionscript classes that compiled in the old environment now get a compile error:
A file found in a source-path must have an externally visible definition. If a definition in the file is meant to be externally visible, please put the definition in a package.I do declare the package in these classes - I think failure to declare the package is the usual reason for this error.To add to the mystery, many classes in this project compile without errors.
I have classes witch resides in this package :com.network.interface_as. When I try to load one class from that package in another class in the same package like this:
I have a Flex 3.2 application for which I am developing a custom style. Basically the first stylesheet gets applied first, and then my custom stylesheet. I am wondering how I can completely empty a value set in the first stylesheet with a value set in the second. The value has to be blank because if the horizontal-center value is set then any other positioning values are ignored.
if i add = null, (even in the class whose method i am overriding) i get that error: override protected function rollOverHandler(e:MouseEvent = null):void {
I'm tryng to make a public static method call another method, but Flash throws error 1180, sayng that the method called by the static method is undefined.
i have a fortran method which creates random numbers. i want to convert this method to a flash method . I want to get numbers from this method and use them in the delay method of flash.
the fortran method is the folowing
real znew1 , zold1 ,a,m,z1,p,TIME1 a= 16807. m=2147483647 B=2
I have a class called Animal that has a method foo() and I call it out within the Animal class.
Code: protected function foo():void { trace("Animal"); }
I also have a class called Cat that extends Animal and overrides the method foo()
Code: override protected function foo():void { trace("Cat"); }
However when calling the function foo() from the superclass it traces out Animal not Cat (using a Cat object).How can I make superclass call out methods in the subclass?
