  1. POFlex How To Call A Function With A Variable Number Of Parameters?
    text
    copied!<p>Let's Say I Have This Class:</p> <pre><code>package{ import flash.display.Sprite; public class Main extends Sprite{ public function Main(){ trace(getAverage(1,2,3)); trace(getAverage(1,2,3,4)); trace(getAverage(1,2,3,4,5)); } public function getAverage (...numbers) { var total = 0; for (var i = 0; i &lt; numbers.length; i++) { total += numbers [i]; } return total / numbers.length; } } } </code></pre> <p>How do I accomplish the "opposite" of this? Namely, how could I now CALL 'getAverage' with a dynamic number of paraemters?</p> <p>For instance, if I wanted to do something <strong>LIKE</strong>:</p> <pre><code>var r:int=Math.random()*6; var a:Array=new Array(); for (i:int=0;i&lt;r;i++) { a[i]=Math.random()*22; } // Now I have 'r' Number Of Parameters Stored In 'a' // How Do I Call getAverage, with all the values in 'a'?? // getAverage(a) isn't right, is it? // I'm looking for something similar to getAverage(a[0],a[1],a[...]); var av:Number=getAverage(???); </code></pre> <p>What I want to know, is if I have a function that takes a variable number of arguments, that's great, but how can I CALL IT with a variable number of arguments, when that number isn't known at runtime? Possibly it's impossible... I'm just not sure, since 'callLater' seems to be able to take an array and generate a dynamic number of parameters from it somehow...</p> <p><strong>NOTE:</strong> Answers consisting solely of "Why Do You Want To Do This?", will be downvoted.</p> <p>P.S. This <strong>IS NOT about calculating Averages!</strong> I <em>REALIZE</em> There Are Way Simpler Ways Of Doing All Of This! (I could just write getAverage to accept a single array as its only parameter) The Above is just an EXAMPLE to Illustrate my Question. HOW TO PASS A DYNAMIC NUMBER OF PARAMETERS TO A FUNCTION?</p>
