text: We're not going to have that functionality in this version of AS3. You'll need to do something different. Like simulate by creating the object with a no-arg constructor and then having a well-known function like "initArgs" which you could call via Function.apply.
  public function createInstance (className:String, args:Array) : Object { var myClass : Class = getClassByName(className); var inst : Object = new myClass(); inst.initArgs.apply(inst, args); return inst; } Matt -----Original Message----- From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Vadim Melnik Sent: Thursday, March 02, 2006 5:28 AM To: flexcoders@yahoogroups.com Subject: [flexcoders] Re: How to dynamically invoke AS3 class constructor ? This code is similar to "var a:* = new A(1,2,3);" in my original post. Arguments count is statically specified at compile time. But I am looking for the way to pass different number of arguments to constructor at runtime. Arguments type and count are unknown at compilation time, that is why someArgs:Array used. Flex 1.5/AS2 implements class constructor as AS2 Function object and we were able to call it like Function.apply(context, args). Now we are looking for something similar in AS3... -- Thanks, Vadim Melnik. --- In flexcoders@yahoogroups.com, Alisdair Mills <[EMAIL PROTECTED]> wrote: > > haven't tried it but maybe try... > > import flash.util.getClassByName; > > then.... > var ClassReference:Class = getClassByName("A"); > var instance:Object = new ClassReference(1,2,3); > > cheers, Al > > > > On 2 Mar 2006, at 12:25, Vadim Melnik wrote: > > > Hi All, > > > > It is going to be easy, but I can't figure the way to implement it. > > We have certain Class object referencing to some class with > > constructor accepting any ... numbers of arguments.
