* vs Object

[Paul Hardiman <pa...@hardiman.com>]

Vector.<*> seems to cause abc byte code issues. Compiler seems happier with Vector.<Object>.
What’s the difference?

Also something I forgot you could be interested in, even though it doesn't matter for Vector.

var undefinedValue:* = undefined; // returns undefined
var undefinedObject:Object = undefined; // returns null

but

vector.push(undefined);
objects.push(undefined)

Both insert null as the type vector checking and conversion seems to be on Object.

So, at the end, it seems there are no differences in the usage, both are equivalent to Vector.<Object>, personally , I still use Vector.<*> when I've got no idea what it will go inside (uint, int, Object, ...) and use Vector.<Object> when I don't don't the subtype but it is a matter of style, it won't make any differences as far as I'm aware of.

What code and what error do you get ?

> What’s the difference?

* stands for: undeterminated type
Object for: Object and therefore its subclasses, so, given 1 instanceof Object == true

var vector:* = new Vector.<*>(); // will return a Vector.<*> even though vector is typed *
var objects:Vector.<Object> = new Vector.<Object>();

vector.push(1);
vector.push(new Object());

objects.push(1);
objects.push(new Object());

both work.
