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?

View 6 RepliesIs 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?
View 4 RepliesIs 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?
I am trying to put getters and setters into my inteface but I get the following error1053:

How are you suppose to put getters and setters into a interface. for as3
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.
View 2 RepliesWhat'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.
1. How parameters we can send to a Setter ?
2. What are the best practices of setters and getters?
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.
package view {
import flash.display.Sprite;
public class Main extends Sprite {
[code].....
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]

View 7 RepliesI 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?
anyway im using flash as3 for about 6 months, and im still kinda confuse in this things like getters and setters, and idk what you call that but here's and example :
private function myBoolean():boolean
{

idk how to use it, and what it differs from getters and setters,
how bad is this practice? I am having trouble getting to some stuff so i am taking the easy way out
Code:
private static var _interrupted:Boolean;
public static function setInterrupted(value:Boolean):void{
_interrupted = value;
}
my main class is Editor my sub class is a CustomTextField i need my Editor to keep track of what the active CustomTextField is, since there can be more than one. i want to have a variable, activeTextField:String to keep track of the active CustomTextField. i created getters and setters on editor to keep track of activeTextField. how do i call these getters and setters from the editor w/out using static getters and setters on the editor? this has to be confusing to read because i am utterly confused writing it...

View 1 RepliesI think this is a pretty simply problem but I do not seem to be able to pull it off. Basically I have a parent class A, and a child class B.Class A instantiates class B with addChild.There is a shared object which is being updated from a java server (red5) that has an event listener attached to it in class A.I have a function in class A which will pass certain, specific updates from this shared object to class B.The problem occurs is that when class B is instantiated, the event listener from class A doesn't work anymore. I have not removed the event listener from A.?

I'm beginner in Flex 4. I'm trying to pop up a Flex WindowTitle custom component, and after the user choose some values, the parent window must be refreshed.I'm showing the modal window, the user can't interact with other components, but the problem I detect is the execution of the program flows, even I choosing to show the Input window as modal, the next methods to refresh the page is called before the user close the modal page. I don't know if flex or ActionScript works different from Java, where I used to code. see the comments on the code example:

For a program i'm writing I need to marshal ActionScript classes to a format that is later to be read by Java (and back again).
What solutions exists for such a need ? Is there a way (like when using Java through XMLEncoder/XMLDecoder) to generate that XML using standard flex libraries (that would be compatible with later decoding using XMLDecoder) ?
EDIT Yes, this question is a duplicate of Are there any tool mapping of JavaBeans to ActionScript Class through xml serialization and deserialization?, but I will accept correct answers and eventually start a bounty if no answer satisfies my needs. (in other words, i plan to make the previous - unanswered - question a duplicate of mine).
EDIT 2 To be even more precise, I have an application divided in two parts : one Flex GUI and one Java core. They communicate over a non http layer which requires data to be sent in XML. In this context, I replicated my Java objects in Flex (using GAS3) and now want some of these objects to be sent from Flex to Java and back again.For that purpose, I have to serialize objects (on the Flex end) in XML and deserialize them in Java (and all that back again).
[code]All clips are squared.Ok, on the PlayerPlane, there are little soldiers, which have hotkeys. The effect I'm trying to create is I want to position the GameStage so that the currently selected soldier appears in the center of the GameClicker clip.The GameStage is movable by the player (to scan other areas of the map)by holding the CTRL key, so it's easy to kinda lose track of where your players are.I have tried using localTo Global and globalToLocal techniques, but I think I'm lost on the actual math of getting the GameStage to move the correct distance so that the selected soldier is centered to the GameClicker.[code]

View 1 RepliesSelect a school listed in the first datagrid, and display all the student records /details of that school in the next datagrid. But, since datagrid is editable and requirement mentions : "Use a Wrapper class around the object to get the data, set the same and save. Ensure wrapper is bindable to take into consideration the updates being made to datagrid text fields."
I have an object which is a type of a Data Access Objects i.e. DO.
mySchool:mySchoolDO.
The mySchoolDO is an actionScript class of following code :
public class mySchoolDO
{
public var schoolName:String;
public var schoolLocation:String;
[code]....
The showSchoolStudents will display all the details of students on to the datagrid. But, my datagrid is editable. And, I want to use WRAPPER CLASS around this object such that
a> I can retrieve individual values as present in studentsDO i.e. studentID, studentCourses, studentGender, studentPhone.
b> I shouldbe able to set the values as they are updated in the visual datagrid.
c> Finally save all the data and submit on submit click.
