When using ObjectUtil.copy() on my object, I get the following error
Argument count mismatch on foo.bar::MyObject(). Expected 1, got 0.
MyObject's constructor takes in one parameter. Is there a way for me to clone, or copy it?
I have the Class and the parameters of its contructor as an object. What I need to do is a function that returns an instance of this class, passing this parameters to the constructor.
This is the code:
Some random and unmodifiable class:
public Foo {
public function Foo(a:int, b:String) {
// constructor
}
}
And some function (in some another class):
function bar(params:Object):* {
var baz:Foo = new Foo(params.a, params.b);
return baz;
}
What I need to do is make this function generic, without pass params as parameter to Foo constructor because I can't modify it. Something like:
function bar2(clazz:Class, params:Object):* {
var baz:* = new clazz(/*some magic way to transform params in comma separated parameters*/);
return baz;
}
I am working on a side-scrolling platformer game. Because of this, I have a class that acts as a floor. I also have a class representing enemies. I am having problems with passing a parameter to a custom class' constructor. The class (SkullDemon.as) extends MovieClip. I am trying to pass an instance (called "floorL1") of a customer class called "FloorLevel1." "FloorLevel1" also extends MovieClip (I do not have a written .as file for "FloorLevel1"; I just exported the floor MovieClip to that class).
I am trying to pass an instance of "FloorLevel1" so that the "SkullDemon" object can land on the floor just like in a platformer. My main class is called "TME2_Main." This is the class from which I try to pass the "floorL1" instance to the "SkullDemon" class. This is how I try to create a Skull Demon instance and pass "floorL1" to its constructor:

What am I doing wrong here? I have spent a while looking for solutions (including moving code outside of TME2_Main's constructor),
I want to serialize ThugtrisShapes' children (heritage/polymorphism) but his children like Right_LShape take constructor parameters,i have to assign it a default value (in my case null because they receive an Array type), but i get this error even when implementing IExternalizable.
Take Note: IForm extends IExternalizable.
here is a link i found about it but it still does not work...[URL]
Code:
public class ThugtrisShapes extends Sprite implements IForm
{
var squares_:Array;
var numsquares_:int=MAX_SQUARES;

I know that not all class' can be cloned , but cloning is an important aspect of OO programming.... There should be a solution for my problem,besides taking the parameter out of the constructor and add a setter.
Is it possible to create a class instance dynamically and specifiy the constructor parameters dynamically?
So for example, imagine I have a class 'TestClass' which as constructor takes two parameters, (Array, int)[code]...
I know I can create instances from a string like this:
var classFromClassPath:Class = getDefinitionByName(classPath) as Class;
var instance:Object = new classFromClassPath()
I know I can call some function with a parameter array like this
var x:Function = someFunction;
x.apply(null,args);
But does anyone know if I can pass parameters like that when I construct a class?
I am trying to store my Application.application.parameters to my local variables
For example: var myVar:Object = Application.application.parameters;
So here is the tricky part, is I do ObjectUtil.toString(myVar)
I can see all the values and properties. However if I do myVar.clientName or any other properties I always get null or undefined.
I've been starting to create my own classes for a project and I've encountered an error that I don't know how to solve. This is for a Game class collection.
How do I create an object with ActionScript if I only know the name of it? I have a class that should add an object as a "grid" and place it accordingly, so if I have a Square box that I want to place by 4x4 on the screen it calculates it automatically. Well, that's the goal anyway.
I have a function in my Grid class, Add_Background that accepts an Object to be added as the grid background. I use a movieclip (don't know if I can use a graphic element).
I call the function myGrid.add_background("name_of_my_movieclip") or myGrid.add_background(new name_of_my_movieclip());
The first one I don't know how to use, I don't know how the syntax for creating an object this way (etc: grid[a][b] = new name_of_my_movieclip() doesn't work...) so there has to be some other kind of way on how to pass this to the function and that it knows what to do with it.
The other thing I've tried is passing the object to the function (new Grid_Background() etc) but I can't clone the object anyway I try it and the ActionScript reference site says there's an mx.utils.ObjectUtil that I can use for this, but I have no access to it that I know of (tried it).
I've read through the Sticky in ActionScript 3.0 forum and looked through other threads in the topic but maybe I'm not using the right search terms. My problem is creating a new object in the constructor method, I've created a package "com.weenz.shutters" and created many class files within that package. The compiler is giving me the following 2 errors for the "Window.as" file[code]...

I'm unsuccessfully attempting to instantiate a reference of a class that is passed as a parameter to another class. In this example there are 3 classes:
MainClass, Canvas, MyCircle
From the MainClass I am creating an instance of Canvas, which is passed a class reference of MyCircle as I want to create instances of MyCircle from within Canvas. However, the MyCircle constructor contains required parameters that are created from within Canvas. How can I pass and instantiate a class reference with required parameters?
MyCircle:
package {
//Imports
import flash.display.Shape;
//Class
public class MyCircle extends Shape {

I'm working on a very simple dependency injector, reflecting on a types constructor parameters.But when ever I use the describeType on my custom classes, all I get in the constructor packet of the returned XML is something like this:

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.
View 4 RepliesI just posted a message asking how to call a method from the constructor which has the parameters e: Event. I mistakenly ticked that post as answered when in reality it isnt. I was told I could add = null in the parameter of the function to make it work, like this:

So I usually use an object in the constructor to receive the parameters like new Class({param1:00,param2:0099,etc).To be able to access those parameters from other functions inside the class I create an object, and copy it:
Code:
public class MyClass {
var params = {};
public function MyClass(p){

I've got a function wich can accept a varible number of parameter with a rest operator. I want create an object passing the argument collected with the rest operator directly to a constructor without create an object and call an initializing function and without passing the entire array but the parameters ah I do with apply() function.

View 1 RepliesThere is a library component represented by Class A. But constructor of this class requires some parameters. When the component needs to be added dynamically, it's fine because of code :
var abc:A = new A(param1,param2)
But what if my movieclip is already present on the stage. I notice it gives out error, that the parameters are null.
Is their any way to insert constructor parameters for movieclips already on stage.
I have my flex object embedded to JSP page.The JSP page retrieves user information like user name and group from portal profile object and stores in http session parameters. The flex Object makes a remote call to Employee.class to perform persona based operation.
I retrieved the session id in JSP and also in the Employee.class both are same. But I am not able to retrieve the username stored in the http session from FlexSession. I read in the internet that the FelxSession will hold all httpSession information as well. It's always coming as null. Correct me if I am wrong.

View 1 RepliesI found a really weird behavior when using deep copy for objects (ObjectUtil of Flex framework).Imagine we have a class B which extends class A. Class A has property body which is of type ByteArray.I create object b (instance of B). Then I make a deep copy object bCopy, BUT this bCopy object does not contain body property at all! All others properties (of scalar types) defined in Class A are copied properly.When I define property of type ByteArray directly in class B, then this property is copied properly..

How to create new class instance without calling constructor function, meanwhile constructor function must exist and is requiring 1 parameter.

Is it OK to use the constructor to set properties for a value object class or must I use dot notation and set each one, one-by-one? I recently read an article that was saying I should do it one-by-one as value objects should only contain properties and went on to say using the constructor is not OK (best-practice wise).
Code:
