Actionscript 3- Vector to Array

Actionscript, Flex Add comments

There’s currently no way to convert a Vector to an Array (or ArrayCollection), so here’s a simple util that’ll do it. Accepts any type within the Vector, so the parameter is just an Object, then we convert it back to a vector before the Array conversion. Phew.

public static function VectorToArray( v:Object ):Array
{
    var vec : Vector. = Vector.(v);
    var arr : Array = new Array()
    for each( var i : Object in vec ) {
        arr.push(i);
    }
    return arr;
}

    Hi there!
    
Just found this post. Am I allowed to clean and speed it up a bit?
    

    public static function VectorToArray( v:Object ):Array
    
{
    
    var vec : Vector. = v as Vector.,
    
        arr : Array = [];
    
    for each( var i : Object in vec )
    
    {
    
        arr[arr.length] = i;
    
    }
    
    return arr;
    
}
    

    Cheers,
    
 Daniel
    

    PostScriptum: Note this: fast instanceiation(I think the word is wrong, but you know what I mean :) ) is like
    
new ['here', 'it', 'is'];
