Actionscript 3 :: Packages Name Conflicting With Getters And Setters?
Jun 13, 2010
I've came across this compilation error a while ago.. As there's an easy fix and I didn't find anything relevant at the time, I eventually let it go.I just remembered it and I'm now wondering if this is really part of the language grammar (which I highly doubt) or if it's a compiler bug. I'm being purely curious about this -- it doesn't really affect development, but it would be nice to see if any of you have seen this already.

import flash.display.Sprite;
public class Main extends Sprite {

Is there a way to synthesize getters/setters in AS3? It's very common that you have a class with lots of variables, especially in math calculations (Model in MVC pattern), that you'd like to expose. Is there something like synthesize property in Objective-C, that allows to generate getters/setters?

Is there a way to use getters and setters for Vectors?Say, in my Main class, I would like to write
myVector.push(item);
and in another class, I have written:
public function get myVector():Vector.<int> {
return _opponentCardList;
}
public function set myVector(myVector:Vector.<int>):void {
_myVector = myVector;
}
This doesn't really work as you have to set _myVector to a Vector. But what if you just want to push(), pop() or splice?

package

import flash.display.Sprite;
public class AbstractTarget extends Sprite [codee]................
And then I have a class called "Target" that extends AbstractTarget...how do I access the __movement property? Do I have to write the getter and setter in my Target class also and override both functions/methods?

fact: using my setup, a class that inherits from another class does not inherit the parent class' getter/setter methods.

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?

In the following:
//track of whether the player has the key public function get hasKey():Boolean {
return _hasKey;
} public function set hasKey(keyState:Boolean) {
//trace(keyState);
_hasKey = keyState; }
These functions don't even work until a value is passed to keyState in the set function correct? As you can see I did a trace keyState and the trace didn't return anything until it was true.

I have a class (Wall) that inherits from Sprite.Sprite already has width and height properties. But for wall, I need to do some other additional calculations when the properties change (f.e. make sure the new size won't cause it to overlap any other walls).So, how do I set the width property inherited from the Sprite class from within the width setter of the Wall? (or perhaps there is an alternative way to do my bounds checking whenever width is set?)[code]

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?

if getters and setters are the best option in a specific case. The case is when I have class 'A' instantiating classes 'B' and 'C'. Class A contains public getters and setters for classes B and C to access so data is centralised.Is this best practice or would it be best to pass the data to classes B and C through parameters?

I don't understand why adobe set them up that way. As far as I can tell, all the setter does is change the value of the varible and nothing else. does anyone know why adobe set things up this way or what the x and y setter do other than changing the value of the varible?

I am plain stumped. I am working in F8/as2.0.I have a class that extends the MovieClip class. I have a blank_mc in the library that is linked to the class. Here is the constructor:
ActionScript Code:
public function MyMC (target_mc:MovieClip){
var _mc:MovieClip = this;
_mc = target_mc.attachMovie (.....);
}
That works all fine and dandy. Where I am having issues is basically I have properties x, y that DON't overwrite the _mc's _x & _y props. Instead, the use getter & setters that take values and then calculate the needed number to set the actuall _mc._x, _y props. This doesn't seem to work at all and i don't know why. Here is the code:
[Code]
So I got this to work by NOT extending the MC. Instead I have a variable ref to a _mc prop in the class.However I am unable to set event functions to it even if I make some ref to the _mc prop. Is there a good way of approaching this by say a decorator pattern?

I'll admit that I'm a scripting novice. So I'm having trouble with some onRollOver, nRollOut, and onDragOver in some code of mine. It's an XML driven menu I borrowed from a tutorial. It allows you to drag items into any order. Anyway, I've tried to implement a movieClip that is visible when you RollOver as well as a seperate movieClip that is visible onPress and onDrag. The code may be too ambiguous but maybe not. I'm at my wits end. Starting to thrash code around. What I'm aiming for is movieClip that appears when you rollOver and goes away when you rollOut. And a movieClip that stays visible when you hold and drag the item around.

I am using Flash Builder 4 and need a VideoDisplay component that works with Cue Points. The newer version of theOSMF classes that Flex's VideoDisplay are based on handles this already. The idea is to roll my own VideoDisplay component rather than monkey patch the existing one. To do this, I have created a project with the newer version of the OSMF classes, and another project with which I would build the new VideoDisplay, in a separate package name.
The issue is that since the Flex 4.1 SDK contains the majority of the OSMF classes with their original package names, a statement such as import org.osmf.media.MediaPlayer; references the class located at

My question deals directly with ActionScript 3, although it could possibly appear in other languages. Consider the global trace function found in AS3. Calling the method requires no imports and is globally available from all classes.
class A {
public function A() {
trace("Hello, A!"); // Hello, A!
}}
Now, what if I create my own class method of the same name? In AS3, if I have a class method trace and then make a call to trace elsewhere in my class, the call is made to the class method over the global function. Essentially, I've blocked my ability to call the global trace method.
class B {
public function B() {
trace("Hello, B!"); // no output
} public function trace(s:String):void {
// do something else.
}}
Now, I know the obvious answer is to say, "don't create a class method called trace." But what if I'm unaware of the existence of the global trace function? Or what if I have a desire to "override" or "block" the global function? Is doing so bad programming? Or is this just another example of how AS3 is a poor object oriented language?

Dear goodness, am I the only person on the web trying to send a VO object from Flash to AMF where the properties are read only/getters? If I add a setter that does nothing but throws an Error it works. If no setting is present in Flash, it fails. Is there a way to send objects to AMF that have getters and not setters?

I need to change a text field every time values in an array is updated, and I tried putting the code in the setter. However, the code is not being called. Even if I do this
public function set resources(value:*) {
//this function does not seem to matter at all
}
Nothing happens. I think AS3 overrides setters for arrays, how do I get the functionality other than inserting a changeTextFields(); every time I change the array?

I'm finally reading up on commenting code with ASDoc (http:url]....) but the way ASDoc is set up doesn't seem to agree with the way I write my getter/setters.Here is how I write them:
Code:
//I want to add the ASDoc tags here, before this chunk of code
private var _enabled:Boolean = true;
public function get enabled():Boolean[code]...
if I ad the tags where I want them, if I understand correctly, they will comment the private variable instead. Bummer.So, either I change the coding style I have been using for the past three years, or insert the tags inside of my code, making it ugly and less structured. I'm leaning towards option A.how do YOU write your getter/setters so they are ASDoc friendly?
