Re: [Flashcoders] create an object of type defined with a string
If you need an object that already exists to be converted into an instance
of the class you can use the XT Prototype class
Prototype.makeInstanceof(obj, Array);
and using Zimmen's suggestion
Prototype.makeInstanceof(obj, _global[tType]);
good luck! you'll find the class at
http://codext.com/code/9

test = makeObject("Array")
as well (this is what the findClass method does eventually. :)

If you were using Flex, I think there is a way to do it: let us know if you use
Flex.

Asunto: [Flashcoders] create an object of type defined with a string
I want to have a function makeObject(tType:String) which returns an object
of class tType. So makeObject("Array") should return a new Array object. Any
good way to do this? I'm sure it's something simple.
And before you ask, yes, there is a reason why I need to do it this way...

Makes total sense! Valuable info for the rare occasion I do a
Director/Flash hybrid. Thanks for indulging me. :)

I've been hitting some memory problems when using Director's newObject()
function, which creates a new object inside an embedded Swf. Because the
object is unnamed, I have no way to destroy it in the Flash movie - it seems
to go somewhere in the global space. So instead, I'm making my own
tempObject function, which creates a new object in an array pTempObjects in
the Flash movie. When I've finished working with it, I run a
clearTempObjects() function to flush them out.
So I have this function:
function tempObject(tName:String) {
var tObj:Object =
pTempObjects.push(tObj)
return tObj
}
Now Director can call this function, get a new temporary Flash object and
work on it, then tell Flash to do something with the object (eg, setting the
properties of a TextFormat object before applying it to a field), and then
finally clear it out.
More detail than I think you wanted, but since you asked :)

RE: [Flashcoders] create an object of type defined with a string
Danny,
Out of curiosity, why do you need a function that returns an object of a
type passed as a string? It's a neat idea, but I'm scratching my head as to
where one might apply it.

Re: [Flashcoders] create an object of type defined with a string
Hi Danny,
mx.utils.ClassFinder.findClass("SomeClass") returns the constructor
function for a class.
e.g.
var className:String = 'String';
var cls:Function = mx.utils.ClassFinder.findClass(className);
var object:Object = new cls();
Hope that helps,
Ian
