there are classes definitions where all their methods are private my question is why are they private, because i've tried a code wherein i changed all the private access modifier to public and nothing changed!
what if you make an instance of that class with all its method private, how are you be able to access that on another class. coz i know private methods are only accessible to the class where they are declared! will the instance of that class be able to access the superclass's private methods!
on private variables, it's still not clear to me as to why make a private variable and then use a getter and setter, when you can simply make it public! are these variables called static?cause on the way i understand it private functions and private variables are static?
is there a difference between classifying a function 'private' or 'private static' in a singleton? It seems that they both do the same thing. Maybe some difference in performance?
[Code].....
how to retrieve these in other functions.
In my main class (package) I have a function (tipTrendHandler) which creates an object TextBox. The instance in the example is ttrend. The class is imported. However when trying to access the object and apply e.g. a method, declared in another function (e.g. displaySequence) it seems this object is unknown.
ActionScript Code:
package com {
import flash.display.*
import com.mycompany.TextBox;
[Code]....
Okay so you've got your private vars in your AS2 Class, you think they're all safe right? Wrong.
Doing a trace(MyClass.myvar); will spit out an error that the var is private and you can't touch it.
But a trace(MyClass["myvar"]); will work perfectly fine. You can use it normal, without any setters getters outside the class.
Is there a way to protect against this? I think this is a huge security flaw. I know it's simple OOP, but a private var in an object should have rules.
Why static method cant access private properties in the same class?

i'm trying to modify some code and can't figure out what the issue i'm having it. this is the(shortened) code:
public static function Lose():void {
trace("OVER!");
Clock.stop();[code]...
this is the error i get: 1180: Call to a possibly undefined method OverIt.i just want to call a function from inside of the public static funtion.both function are inside this class:
public class Game extends MovieClip {
}
I have the below script as part of a small application I'm building. The script just creates cue-points along a movies timeline so we can add events etc to those cue-points.
[Code]....
It's creating the cue-points well, although I'd like to use the below variable outside of this function.
Code: var stampName When I try and use it I get an access of undefined property error, which I believe relates to the variables being private and within the function - but I can't seem to find a method to get this varibale public.
How do I call a private function from an external ActionScript3 document? I'm working in Flash Builder 4, and I need to call a private function from an external AS3 document. I think I've imported it correctly....
import myapp.utils.WebcamFaceDetector;
import myapp.utils.FaceDetector;
But I want to call a function from "FaceDetector". Here's the part of the code in FaceDetector...
public class FaceDetector
{
private var detector :ObjectDetector;
private var options :ObjectDetectorOptions;
[Code]....
I want to call "private function FaceDetector()" to initiate at a certain point in another AS3 file. How do I properly declare it and get it to run?
These two functions are taken out of my as class file, even though the setInterval is never cleared it only calls generateParticles 1 time. Someone please help me figure this out. I have been messing around with it over an hour but still can find why its only called once. emit is a private var Number declared outside the function in the class.

I'm building a drag and drop quiz. each draggable mc (drag#) has a base class of DragDrop. I want to detect when an drag mc has been dropped on a target
Code:
if(this.hitTestObject(target)) {}
And then add a new drag from the drops Array. so that each time a drag finds its target a new one appears. I tried to make a public var named dropped to switch from "yes" to "no" in the drop function. and even tried making the drop function public.
This code is on the timeline
stop();
var drag1:Drag1;
drag1 = new Drag1;
addChild(drag1);
drag1.x = 100;
drag1.y = 100;

In Actionscript 2 I find that I cannot have a "private function set" without returning the error "A member attribute was used incorrectly." If I change it to "public function set" I'm fine but that defeats the goal of trying to protect the function from setting externally
View 2 RepliesI have written a framework that facilitates RPC calls between AS3 and PHP 5 called FlashMOG. I recently got a forum request that has introduced a pretty bizarre question regarding access control. This will be a lot easier to discuss if you have access to the FlashMOG 0.3.1 client source which is here:
[code]...
The basic idea is that I have a FlashMOGService class which has an RPCSocket member that it may share with other FlashMOGService objects. The idea is that you can create two distinct FlashMOGService objects and have them both connect to the same host/port via socket. I use my special RPCSocket class for two reasons:
1) Let developers use one port but separate functionality into two distinct services...a form of multiplexing i guess
2) RPCSocket adds functionality to the standard Socket class that works to serialize and unserialize data and get it where it needs to go. The essence of the problem here is that created a class with a FlashMOGService object as a member and has tried to assign a private method of his class as an event handler to the FlashMOGService object:
[Code]....
My initial thought is that this should be fine because it's all done within the class. However, when I consider the monkey chain that results in this function being called, it seems almost logical that it wouldn't work. The problem is that the browser freezes when a socket message arrives that tries to call the service's client method, _service.client.firstClientMethod. This client firstClientMethod is attempted when data arrives from the server on the Socket (an RPCSocket, actually). The RPCSocket class deserializes the socket data and extracts an array with a service name, a method name, and an array of arguments. It looks into its own private class variable (an array of services using the RPCSocket) and tries to invoke whatever function was assigned thusly:
[Code]....
I'm guessing there's some kind of infinite loop going on to check access control for the various intertwined classes.
I've worked with AMFPHP for a while, but with Adobe supporting ZendAMF, I was wondering if I should migrate.
One of the major disadvantages for AMFPHP is that class mappings need to be public, so not only does that mean public members on the PHP side, but also on the Flex side. I was wondering if it is the same case for ZendAMF.
I've been taught that when you have a private variable in a class it can't be accessed, let alone be altered, outside of the class. So how come I can do the mentioned actions on an objects private variables within a fla?

private var foo;

Is there any way to mimic the in operator, but testing for the existence of protected or private fields?For example, this:
<mx:Script><![CDATA[
public var pub:Boolean = true;
protected var prot:Boolean = true;
private var priv:Boolean = true;
[code]...
When I want to see:
pub: true
prot: true
priv: true
bad: false
I need it in FlexUnit to test private methods. Is there any possibility to do this via reflection by using describeType or maybe flexUnit has some build in facility? I dislike artificial limitation that i cannot test private functions, it greatly reduces flexibility. Yes it is good design for me to test private functions, so please do not advise me to refactor my code. I do not want to break the encapsulation for the sake of unit testing.
View 4 Repliesis it possible to mark parameters as private, only accessible/useful for the class that owns the function?
example:
//PRIVATE CLASS (.SWC)
public function set AutoBounce(value:Boolean):void
{
if (value)
[Code].....
rather than redirecting, is there any better way to dealing with this issue? maybe "better way" is a poor choice of words. is there a way to refactor this code without using a forwarding function or having to force the user to include the event parameter.
I would like to implement some security in some of the Flash/PHP applications that I have. I have some Flash apps that communicate with PHP files, and the PHP is sending the data as get string (E.g.: name=John&sname=Doe&age=24&balance=12.4). Instead of all these variables, I would like it to send a single variable (E.g.: flashvar=jr9afgaw9-fg90agfawf7gw) that would contain those values, so then Flash would decrypt the string and get the real and useful vars.
I want to encrypt this using a private key and use the same private key to decrypt this inside Flash. If someone would want to decode the message PHP sends, he would have to decompile the flash file and find the private key I'm using in Flash to decode the message and then decode it. The reason I posted here is because I want to use an encryption algorithm that allows only the use of a private key for encryption/decryption.
what does public and private mean in this statement and when do I need to use it?this is not my code just using it as an example.
package {
import flash.display.Sprite;
import flash.net.URLRequest;
import flash.net.URLLoader;

Is there a way to use the sortOn() method of the Array class to sort an array of objects by a private property?I've tried using a getter function, but Flash didn't like it.It doesn't seem right to leave a property as public, but the sortOn() method is very handy -

I can't seem to get my private variable, x, to be private. From my understanding of private variables, tracing n.x should throw an error, and adding 150 should throw an error. I've tried changing the variable's name, and the cast type, to no avail. The first trace goes through, the addition goes through, and the second trace goes through.
I'm new to classes, so I could easily be overlooking something vital. But the vars need to be private, because I want to use get/set to update the variables when one or another changes. For instance, if 50 is added to the y value, the magnitude and unit vectors would change, so I want to update them using getMag and getUnit. That whole system would be thrown off if the user had direct access to the properties.

I've heard it's considered best practice to keep all class properties private and to change them using getter and setter methods.
View 5 Repliesmy understanding of extending classes is that you gain all the functions and methods of that class thus You could over ride any one of them. How ever I am confused on weather or not you inherit and can over ride private methods of the class you are extending or if you have to have all methods public in an extended class.

Can ASDoc be set to document private members ala JavaDoc?
View 1 RepliesI have flash (AIR) application running on a single controlled system (there is only one computer running it and nobody has access to it).I will host some files on Amazon's S3 and I need to make sure that only my flash app running locally on that computer can access those files.I'm wondering what the best (most secure) approach would be for doing this.My initial thought is to make the files on S3 private and store the secret key on the local computer running the flash app. Then when I needed to access the files from flash I would send out an authenticated query string with some expiration time. The only problem with this is that I don't know how to generate the S3 signature in flash. Also I'm a little skeptical about storing the secret key on the flash machine (even though it's a privately owned machine with no other users using it).Is there a better approach perhaps?I have access to a server with PHP, so I could maybe use that as some kind of proxy, I'm just not sure how while keeping the file access secure and not creating a bottleneck through the web server (as opposed to direct access to S3).
View 1 RepliesI try to serialize objects with their private attributes, in Flex.
The introspection API does not seem to allow it:
"The describeType() method returns only public members. The method does not return private members of the caller's superclass or any other class where the caller is not an instance."
Is there another way for an instance to know the name of its private members?
