    <p>There is a function called forEach which both Vector and Array has which you can use. Basically it calls a function for each element in the vector. This is how it works:</p> <pre><code>var myVector:Vector.&lt;Foo&gt; = new Vector(); var myArray:Array = []; myVector.forEach(arrayConverter); function arrayConverter(element:*, index:int, array:Array):void{ myArray[myArray.length] = element; } </code></pre> <p>But I couldn't find a function which just moves all the values from the Vector to an Array. Another solution could be that you create a class which extends the Vector class and then you have a public function called toArray() and then you have that code in that function so you don't have to write it each time you want to convert. </p> <p><a href="http://help.adobe.com/en_US/AS3LCR/Flash_10.0/Vector.html" rel="noreferrer">Vector documentation</a> </p> <p><strong>Edit:</strong> Found this old question today and thought it would be interesting to do a benchmark test of all the different methods this sunday morning. </p> <p>I used a vector with 1000000 items in and made 2 tests for each loop. One using the built in array functions push and one using regular array operations.</p> <ul> <li>For loop, not push: <strong>520</strong> ms</li> <li>For loop, push: <strong>1027</strong> ms</li> <li>Foreach loop, not push: <strong>1753</strong> ms</li> <li>Foreach loop, push: <strong>2264</strong> ms</li> <li>While loop, not push: <strong>2775</strong> ms</li> <li>While loop, not push: <strong>3282</strong> ms</li> <li>Util loop, not push: <strong>4059</strong> ms</li> <li>Util loop, push: <strong>4570</strong> ms</li> </ul> <p>And here is a benchmark using 1000 items:</p> <ul> <li>For loop, not push: <strong>1</strong> ms</li> <li>For loop, push: <strong>2</strong> ms</li> <li>Foreach loop, not push: <strong>2</strong> ms</li> <li>Foreach loop, push: <strong>3</strong> ms</li> <li>While loop, not push: <strong>3</strong> ms</li> <li>While loop, not push: <strong>4</strong> ms</li> <li>Util loop, not push: <strong>4</strong> ms</li> <li>Util loop, push: <strong>5</strong> ms</li> </ul> <p>Basically it's when you get over 10 000 items you start to see the real difference. So between 0 and 10 000 items it doesn't really matter which you use. </p> <pre><code>package { public class Loops{ public static function forLoop(vector:Vector.&lt;Foo&gt;, usePush:Boolean = false):Array{ var result:Array = []; for(var i:int = 0; i &lt; vector.length; i++){ if(usePush){ result.push(vector[i]); }else{ result[result.length] = vector[i]; } } return result; } public static function foreachLoop(vector:Vector.&lt;Foo&gt;, usePush:Boolean):Array{ var result:Array = []; for each(var key:String in vector){ if(usePush){ result.push(vector[key]); }else{ result[result.length] = vector[key]; } } return result; } public static function whileLoop(vector:Vector.&lt;Foo&gt;, usePush:Boolean):Array{ var result:Array = []; var i:int = 0; while(i &lt; vector.length){ if(usePush){ result.push(vector[i]); }else{ result[result.length] = vector[i]; } } return result; } public static function arrayUtilLoop(vector:Vector.&lt;Foo&gt;, usePush:Boolean):Array{ var result:Array = []; function arrayUtilForeach(element:*, index:int, array:Array):void{ if(usePush){ array.push(element); }else{ array[result.length] = element; } } vector.forEach(arrayUtilForeach); return result; } } } </code></pre> <p>I used the getTimer function to do the benchmark, so it might not be 100% accurate but there's so much difference between the different loops so I don't think it matters.</p> <p>I hope someone found this useful. </p>

    1. COvery nice, but extremely slow ... you realize how many calls this makes?

    2. COyes, in my opinion it's nicer than using a for/for each loop. It's a function call for each element in the Vector. How much slower exactly is this approach?

    3. COyou don't want to call myVector.length in every loop. by removing it i've more than doubled the performance, http://pastebin.com/0waTqaER checking length each time = 491 not checking length each time = 209

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
