RE: [flexcoders] Re: Clone / Copy Array

[Bjorn Schultheiss]

The bytearray option is the best function clone(source:Object):*{     var myBA:ByteArray = new ByteArray();     myBA.writeObject(source);     myBA.position = 0;     return(myBA.readObject()); } This will guarantee all nested Objects are not references. slice() will copy the array but the objects within the array will remain references.   Regards,   Bjorn Schultheiss Senior Flash Developer QDC Technologies   From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Daniel Sent: Thursday, 14 September 2006 6:09 AM To: flexcoders@yahoogroups.com Subject: [flexcoders] Re: Clone / Copy Array Thanks for your reply, however, I've already seen that solution. What I'm looking for is a more explicit solution. I have an array and want to copy it into another array.
