[Flashcoders] Array like access to custom class?
Can I provide array like access to a custom collection object?
E.g.
Class MyClass
{
private var myArray:Array;
public function getArray():Array
{
return this.myArray;
}
}
This would allow access to the array items as so:
var someClass:MyClass = new MyClass;
thisItem = someClass.getArray[0];
How can I change it so I can achieve the same thing but with access to
the items like this:
var someClass:MyClass = new MyClass;
thisItem = someClass[0];
Hope that makes some sort of sense?
Cheers,
DannyT

Use __resolve:
class MyClass
{
private var myArray:Array;
public function __resolve(name:String):Object
{
if (!isNaN(name)) {
return myArray[Number(name)];
} else {
return false;
}
}
}
But it will not strict type properly at all, so you lose major
benefits of using as2 this way. I'd do it:
class MyClass
{
private var myArray:Array;
public function elem(n:Number):Object
{
return myArray[n];
}
}
And:
var someClass:MyClass = new MyClass;
thisItem = someClass.elem(0);
Then you will get proper validation of argument, parameter and return types.

Re: [Flashcoders] Array like access to custom class?
someClass.elem(0) = myObj; Nope - of course not. elem is a function - you can't use it that way. You can do anything you like, though. Create your own function for instance: someClass.setElem(0, myObj); Or a general addElem, that doesn't take a position argument but just pushes to the end: someClass.addElem(myObj); Anything you like :) -- Morten Barklund - Information Architect - Shockwaved Gothersgade 49, 4th floor - DK-1123 Copenhagen K, Denmark Phone: +45 7027 2227 - Fax: +45 3369 1174 ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
Re: [Flashcoders] Array like access to custom class?
Can I provide array like access to a custom collection object? The easiest way would be to extend Array. Then you start with all the functionality of the Array object, and you can add or remove functionality as needed. ryanm ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
